Equity Release vs RIO Mortgage Calculator UK 2026

Equity Release vs RIO Calculator

Enter your figures below. The calculator runs both products in parallel: a lifetime mortgage (compound interest, no monthly payments) and a Retirement Interest Only mortgage (monthly interest payments, capital unchanged), then shows the total debt and impact on inheritance at the end of the projection period.

What is equity release? Lifetime mortgages explained

Equity release is an umbrella term covering two products that let UK homeowners aged 55+ unlock the value of their home without selling. The dominant product (over 99% of the UK market in 2026) is the lifetime mortgage, which is a loan secured against your home where interest is added (rolled up) to the balance each month. You make no monthly payments. The loan plus all accumulated interest is repaid when you die or move into permanent long-term care, usually from the sale of the property by your executors.

The second, much smaller product is the home reversion plan, where you sell a percentage (typically 25%-100%) of your home to a reversion provider in exchange for a lump sum and a lifetime lease. Home reversions account for less than 1% of new equity release business in the UK and are rarely the right product for new borrowers because the reversion company receives a corresponding percentage of any future house price growth.

The lifetime mortgage market is regulated by the Financial Conduct Authority under the Mortgages and Home Finance: Conduct of Business sourcebook (MCOB) and, additionally, by the voluntary standards of the Equity Release Council. The Council's five core guarantees provide consumer protections that exceed the FCA's baseline requirements, and reputable lenders (Aviva, Just, Legal & General, More 2 Life, Pure Retirement, Royal London, LV=, Canada Life) are all members.

The Equity Release Council reports that £2.6 billion was advanced in 2024, with the average new lifetime mortgage size of approximately £109,000 and the average age of new customers at 70 years. The most common reason for borrowing is to repay an existing interest-only mortgage that has reached the end of its term, followed by home improvements, helping family with house deposits, and supplementing retirement income.

What is a Retirement Interest Only (RIO) mortgage?

The Retirement Interest Only mortgage is a separate FCA-regulated product class created in 2018 to fill the gap between standard interest-only mortgages (which usually end at age 70-75) and lifetime mortgages (which require no income). A RIO is a standard interest-only mortgage with no fixed end date — you pay the monthly interest from your pension or other retirement income, and the capital is repaid in full when the last borrower dies, moves into care, or sells the property.

Unlike a lifetime mortgage, a RIO does not roll up interest. The capital balance stays exactly the same throughout the life of the loan (assuming all monthly payments are made on time). If you borrow £100,000 today and live another 25 years, the eventual repayment is still £100,000 — plus any unpaid interest on the final months.

Key features of a UK RIO mortgage in 2026:

• Minimum age 50 or 55 depending on lender (Hodge Bank from 50, Leeds Building Society from 55, Bath Building Society from 55, LiveMore Capital from 55, Aldermore from 55, Family Building Society from 55).
• No maximum age — the term runs to death, sale or care.
• Capital repayments allowed at any time without early repayment charges on most plans.
• Affordability tested at application — you must prove that your retirement income comfortably covers the monthly interest under stress scenarios (5%-7% future rate).
• Joint applicants must individually pass the affordability test, so the surviving spouse can continue paying after the first death.
• No no-negative-equity guarantee (capital is fixed and is repaid from the eventual sale).

RIO is regulated under the same FCA MCOB rulebook as standard residential mortgages. The product was created precisely to extend mainstream mortgage options into later life, so the regulatory burden and consumer protections are higher than non-mortgage credit products but slightly less prescriptive than equity release.

Eligibility side-by-side: equity release vs RIO

The threshold differences below explain why most borrowers gravitate to one product or the other. Affordability is the single biggest splitting variable.

The split is clear: if you cannot afford monthly interest payments, RIO is unavailable and equity release is your only practical option. If you can comfortably afford the monthly payments and want to preserve the maximum inheritance, RIO is dramatically cheaper because it avoids compounding.

Lifetime mortgage loan-to-value (LTV) by age

Lifetime mortgage borrowing is age-driven because the lender's risk increases with the projected duration of the loan. Younger borrowers compound for longer, so the lender lends a smaller percentage of property value. Older borrowers compound for less time, so a higher LTV is acceptable.

Enhanced (medically underwritten) lifetime mortgages can lift these figures by 10-15 percentage points where the applicant has health or lifestyle conditions that reduce projected longevity. Conditions commonly attracting enhanced terms include diabetes, history of cardiovascular events, chronic respiratory disease, cancer treatment within the past five years, and smoker status.

Worked case study: Margaret, age 65, £400,000 home, £100,000 borrowed

Margaret is a 65-year-old widow with a paid-off home in Surrey valued at £400,000 and a State Pension plus small DB pension totalling £18,000 per year. She wants £100,000 to help her two children with house deposits and to repay a £20,000 credit card balance.

Lifetime mortgage option: £100,000 at 6.5% per annum, compounded monthly, no monthly payments. After 5 years the balance is £138,160. After 10 years it is £190,895. After 20 years it is £364,950. After 25 years it is £504,470. Margaret's life expectancy at 65 is approximately age 87 (22 years), so the projected debt at her death is around £409,000.

RIO mortgage option: £100,000 at 5.5% per annum, monthly interest payments of £458. Capital stays at £100,000 throughout. Over 22 years she pays £120,912 in interest (cash flow from pension). Capital of £100,000 is repaid by her estate from the eventual sale of the home.

Total cost comparison:

For Margaret, the choice depends on her appetite for cash flow risk. If her pension is robust and inheritance preservation matters, RIO saves her family approximately £188,088. If she fears her income could fall (long-term care fees, loss of widow's pension), the lifetime mortgage's zero-payment structure eliminates default risk at the cost of substantially larger interest accumulation.

Worked case study: Geoff and Susan, joint applicants age 70, £550,000 home, £150,000 borrowed

Geoff (70) and Susan (68) own their home outright in the Cotswolds, valued at £550,000. They want £150,000 to fund extensive home modifications (downstairs bedroom, walk-in shower, stairlift) plus a five-year travel budget. Joint pensions are £42,000 per year.

Lifetime mortgage option: £150,000 at 6.3% per annum (best available 2026 rate for this age band), compounded. After 17 years (Susan's projected life expectancy as the younger borrower), the balance reaches £426,300. After 20 years it is £515,750. The borrowers select a 25% inheritance protection guarantee, accepting a slightly lower maximum loan in exchange for a guaranteed minimum to pass to beneficiaries.

RIO mortgage option: £150,000 at 5.4% (best available 2026 rate), £675 per month. Capital unchanged at £150,000. Affordability test: combined monthly net retirement income of £2,940 supports the £675 payment with 22.9% income utilisation — comfortably within the 35-40% lender threshold.

17-year comparison:

• Lifetime mortgage compound debt at year 17: £426,300
• RIO mortgage capital at year 17: £150,000 + £137,700 cumulative interest paid
• RIO saves the estate approximately £138,600 in compounding cost.
• RIO requires £675/month of cash flow from joint pensions; lifetime mortgage requires £0/month.

For Geoff and Susan, RIO is the financially superior choice as long as both retain reliable pension income. The lifetime mortgage is only attractive if cash flow is uncertain or if one spouse predeceases the other and the survivor cannot afford the monthly payments alone (joint life RIO is stress-tested for this scenario in the underwriting).

Worked case study: Helen, age 75, £300,000 home, £75,000 borrowed

Helen is 75, recently widowed, with State Pension only (£11,500 per year) and a £300,000 home in Yorkshire. She needs £75,000 to repay an existing interest-only mortgage reaching the end of its term, plus £10,000 for essential boiler and roof repairs.

RIO is not available because £75,000 at 5.5% costs £344 per month, which is 43.9% of Helen's £784 monthly State Pension — beyond the lender stress-test threshold of 35-40%. Her income simply cannot service the loan.

Lifetime mortgage is the only realistic option. At age 75, Helen qualifies for a 50% LTV lifetime mortgage (£150,000 maximum), so £75,000 sits comfortably at 25% LTV. The 2026 rate for her age band is 6.4%. After 12 years (Helen's projected life expectancy is approximately age 87), the balance reaches £160,200. After 15 years it is £193,150.

Helen's family inheritance is reduced by the eventual interest, but the no-negative-equity guarantee protects them from owing more than the house sells for. If the property grows in value at 2% per year (a conservative UK assumption), the house is worth £380,400 at year 12 — leaving £220,200 of equity for Helen's children, plus the home repairs Helen funded preserved its saleability.

Without the lifetime mortgage Helen would have had to sell her home at age 75 and rent for the remainder of her life. The product served its core purpose: keeping her in her home with adequate cash flow.

The five Equity Release Council standards in detail

The Equity Release Council (ERC) is the UK industry body whose standards have applied since 1991 and represent the consumer-protection backbone of the lifetime mortgage market. ERC member lenders include all major UK providers: Aviva, Legal & General Home Finance, Just, Pure Retirement, More 2 Life, Royal London, LV=, Canada Life, Standard Life Home Finance, OneFamily and Hodge.

1. No negative equity guarantee (NNEG)

The borrower or their estate will never owe more than the property sells for. If the compounded loan exceeds the sale price, the lender absorbs the shortfall — the estate has no further liability. This protects against the dual risk of unexpectedly long lifespan and unexpectedly weak property prices.

2. Right to remain

You have the right to live in your home for life or until you move into permanent long-term care, no matter how the loan compounds. The lender cannot force a sale during your lifetime so long as you maintain the property and meet the basic obligations of the contract.

3. Right to move

You have the right to port the loan to a new property, subject to the lender's criteria on the new home. The criteria typically exclude retirement villages with restrictive covenants, flats above commercial premises, and non-standard construction. If your new home is worth less than your current one, you may have to repay a portion of the loan to maintain the lender's LTV ratio.

4. Fixed or capped rates

The interest rate is fixed for the life of the loan, or capped at a defined maximum. This protects against runaway interest rate rises — important on a loan that may compound for 25+ years. Variable-rate lifetime mortgages exist but are rare and require ERC approval of the cap structure.

5. Independent legal advice

You must receive face-to-face legal advice from an independent solicitor (not the lender's). The solicitor checks you understand the compounding effect, the impact on inheritance, the alternatives you have considered, and the contractual obligations. This safeguard is unique to equity release and absent in mainstream mortgages.

How compounding works on a lifetime mortgage

The single most important concept in equity release is compound interest. Each month, the lender adds the month's interest to the outstanding balance, and the next month's interest is calculated on the higher balance. Over decades, this compounds dramatically.

Worked compounding example: £60,000 loan at 6% per annum

Notice how the interest accrued in the final 5-year period (£96,530, from year 25 to year 30) exceeds the original loan amount. This is the compounding pattern that makes equity release expensive in cumulative terms even at moderate single-digit rates. To slow the compounding, most modern ERC plans allow voluntary partial repayments of 10% of the initial loan per year without early repayment charges. Even modest annual repayments materially reduce the eventual debt — paying £6,000 a year on a £60,000 loan keeps the balance flat.

Inheritance protection options on lifetime mortgages

Most ERC-member lenders offer features designed to preserve a portion of property value for beneficiaries:

• Inheritance protection guarantee. Ring-fence a percentage of property value (typically 25%-50%) as a guaranteed minimum inheritance, in exchange for a slightly lower initial maximum loan. Useful for borrowers who prioritise leaving something specific to children or grandchildren.
• Voluntary repayments. Pay 10% of the initial loan amount per year without early repayment charges. Borrowers can pay any amount up to this annual cap to slow or stop the compounding.
• Drawdown facility. Take a smaller initial lump sum and reserve future borrowing capacity in a drawdown account. Interest accrues only on amounts drawn, materially reducing the average balance and therefore total interest.
• Downsizing protection. Some plans allow you to repay the loan in full without early repayment charges if you downsize after a defined period (often 5 years), preserving inheritance from any equity surplus.
• Interest serviced payments. A few plans allow you to optionally pay some or all monthly interest, switching back to rolled-up at any time. Effectively a hybrid between lifetime mortgage and RIO.

Always ask your adviser to model the inheritance impact with and without these features. The trade-off (slightly smaller loan or some monthly payments) usually preserves £50,000-£150,000 of inheritance on a 20-year hold.

How RIO affordability assessment works

Unlike a lifetime mortgage, a RIO mortgage requires a full affordability assessment under FCA MCOB rules. The lender will test:

1. Confirmed retirement income. State Pension, defined-benefit pension, annuity income, investment income, rental income. Earned income may be considered but with a haircut as retirement progresses.
2. Joint income on death of first borrower. The surviving spouse must individually pass the affordability test. Lenders typically assume State Pension widow's allowance plus survivor's portion of any defined-benefit pension.
3. Stress test at higher interest rates. Most lenders model affordability at a notional 5%-7% rate (the 'stressed rate'), even though your initial fixed rate may be lower. This ensures you can afford the payment if rates rise on later remortgaging.
4. Essential expenditure. Council tax, utilities, food, insurance, transport, medical costs. Affordability is calculated on the residual income after these are paid.
5. Future income volatility. Defined-contribution pension drawdowns and investment income carry an affordability haircut because of sequence-of-returns risk. Lenders prefer guaranteed annuity income or DB pensions for the highest LTV.

The typical affordability threshold is that monthly interest payments should be no more than 35%-40% of net retirement income. Below this threshold the loan is approvable; above it, the lender will reduce the offered loan or decline the application.

Interest rate environment for 2026

The 2026 UK later-life lending market continues to feel the effect of the 2022-2024 base-rate cycle. Lifetime mortgage rates peaked at over 8% in autumn 2023, have softened to a 6.0%-7.5% range in 2026, and are expected to settle in the high 5s through 2027 if Bank of England base rates continue gently falling. Below are typical headline rates for new-build plans, before borrower-specific adjustments.

For exact current rates always check directly with an FCA-authorised independent adviser. RIO rates are quoted as Annual Percentage Rate of Charge (APRC); lifetime mortgage rates are quoted as Monthly Equivalent Rate (MER) or Annual Equivalent Rate (AER). Confirm which basis your quote uses before comparing.

Tax treatment of equity release and RIO

Both products are tax-neutral in most circumstances, but there are subtle differences worth understanding.

Income tax

The capital you receive from either an equity release lump sum or a RIO drawdown is not taxable income — it is a loan, not earnings, dividends or capital gains.

Inheritance tax (IHT)

Reducing the value of your estate via borrowing can lower the inheritance tax bill on death. A £100,000 equity release reduces your taxable estate by the outstanding loan plus interest (assuming property values do not collapse). Provided your overall estate exceeds the £325,000 nil-rate band plus £175,000 residence nil-rate band (where applicable), IHT savings of 40% of the borrowed amount can apply. Always model this with a tax adviser; gifting drawn-down funds within 7 years is subject to the taper rules.

Capital gains tax (CGT)

Capital gains tax does not apply to your main residence under the Principal Private Residence (PPR) relief, regardless of whether the home is encumbered by equity release or RIO. CGT may apply if you have rented out part of the property or used part exclusively for business.

Means-tested benefits

The lump sum you receive can affect Pension Credit, Council Tax Reduction, Housing Benefit and Universal Credit. Capital above £10,000 reduces benefits and above £16,000 typically removes Pension Credit altogether. Drawdown plans (where you take cash in tranches) mitigate this because undrawn funds are not counted as capital.

Always refer to HMRC's guidance on Inheritance Tax and the Department for Work and Pensions on Pension Credit before taking either product.

Common use cases for equity release and RIO

The MoneyHelper service, run by the Money and Pensions Service, identifies the following typical reasons UK borrowers take a lifetime mortgage or RIO. These reasons are quoted at advice stage and consistent across multiple ERC and FCA datasets:

• Repaying an interest-only mortgage reaching end of term. The single biggest use case — about 35% of new lifetime mortgages and RIOs.
• Home improvements and accessibility adaptations. Downstairs bedrooms, walk-in showers, stairlifts, kitchen and bathroom modernisation. Roughly 20% of new business.
• Helping family financially. House deposits for children/grandchildren, business start-up capital, university fees. About 15% of new business.
• Supplementing retirement income. Topping up insufficient pension income, particularly via lifetime mortgage drawdown facilities. About 12% of new business.
• Repaying other unsecured debt. Credit cards, personal loans, car finance. About 8% of new business — controversial because it converts unsecured debt into secured.
• Travel and lifestyle. Cruises, world trips, second-hand car upgrades, hobbies. About 6% of new business.
• Care fees and adaptation. Funding live-in carers, adaptations for declining mobility, respite care. About 4% of new business.

The MoneyHelper guide on equity release provides a comprehensive overview and a decision tree for assessing alternatives before borrowing against your home.

Alternatives to equity release and RIO

Before taking either product, consider the five mainstream alternatives. The Money and Pensions Service recommends exhausting cheaper options before borrowing against a property whose interest may compound for the rest of your life.

1. Downsizing

Sell a larger home and buy a smaller one, releasing the difference in cash. No loan, no interest, no compounding. The downside is moving costs (£8,000-£25,000 typically), stamp duty on the new property, emotional attachment to the existing home, and the loss of potential future house-price growth on the surplus released as cash. Downsizing is usually the cheapest option in pure financial terms but has the highest non-financial cost.

2. Use existing pension savings

If you have a defined-contribution pension or other investment portfolio, drawing down those funds is almost always cheaper than borrowing against the home. The 25% tax-free lump sum entitlement (within the new lump-sum allowance from April 2024) is particularly attractive.

3. Family loans or gifts

Borrowing from adult children or accepting a deed-of-trust over a portion of the property. The capital cost is low or zero, the emotional and family dynamics complications can be high. Always document the arrangement professionally.

4. Standard interest-only mortgage

If your retirement income is robust and you are under 75, some lenders offer mainstream interest-only mortgages up to age 80 or 85. Rates are typically lower than RIO and there is no later-life premium. Eligibility is narrower, however.

5. Government grants

The Disabled Facilities Grant can fund home adaptations up to £30,000 in England. The Warm Homes Discount, Cold Weather Payments and various local authority grants can support specific costs without borrowing.

Costs and fees on equity release and RIO

Both products carry one-off setup costs plus the ongoing interest. Typical 2026 figures:

Many lifetime mortgage providers offer 'free legals' or 'free valuation' promotions that reduce total setup cost by £600-£1,000. RIO setup costs are generally lower because there is no requirement for ERC-approved independent legal advice. Both products are subject to the FCA's MCOB rules on fee disclosure.

Frequently asked questions

What is the difference between equity release and a RIO mortgage?

Equity release (specifically a lifetime mortgage) is a loan secured against your home where no monthly payments are required: interest rolls up onto the balance and the loan plus interest is repaid in full when you die or move into long-term care. A Retirement Interest Only (RIO) mortgage is a standard interest-only mortgage marketed to over-50s and over-55s, where you pay monthly interest from pension income and the capital is repaid when you die, sell or move into care.

What age can I take equity release versus RIO?

For a lifetime mortgage, the minimum age is 55 across all Equity Release Council approved plans. For RIO, the minimum is 50 or 55 depending on the lender — Hodge Bank and LiveMore from 50, Leeds and Bath Building Societies from 55. There is no maximum age for either product.

How much can I borrow?

Lifetime mortgage LTV is age-driven: 25%-30% at age 55, rising to 50%-55% at 75, and 55%-60% at 85+. RIO is affordability-driven: a 65-year-old couple with £30,000 combined retirement income could typically borrow £150,000-£200,000 at 5.5%. Both products typically cap at 60% LTV.

Is interest compounded on equity release?

Yes. Each month's interest is added to the loan balance and the next month's interest is calculated on the higher balance. £60,000 at 6% compounds to £109,460 over 10 years, £199,830 over 20 years, £364,950 over 30 years. Voluntary partial repayments of 10% per year can slow or stop compounding.

Will equity release affect my state pension or benefits?

Equity release does not reduce the State Pension (non-means-tested), but the lump sum can reduce means-tested benefits such as Pension Credit, Council Tax Reduction and Universal Credit. Capital above £10,000 starts to reduce benefits; above £16,000 typically removes Pension Credit altogether. Drawdown plans help mitigate this.

How does RIO interest compare to lifetime mortgage rates?

RIO rates are 5.4%-6.2% fixed in 2026, similar to standard mortgages. Lifetime mortgages are 6.0%-7.5% fixed for life because the lender shoulders longevity risk and the no-negative-equity guarantee. On a £100,000 loan, RIO costs £458/month with capital unchanged; lifetime mortgage compounds to about £352,000 over 20 years with no monthly payments.

What is the no negative equity guarantee?

The Equity Release Council standard ensuring borrowers and their estates will never owe more than the property sells for. If the compounded loan exceeds the sale price, the lender absorbs the shortfall. Applies only to lifetime mortgages from ERC member lenders. RIO does not have an NNEG (capital is fixed and small).

Can I move house with equity release or RIO?

Yes — ERC members guarantee the right to move home, subject to lender criteria on the new property. RIO mortgages can also be ported on lender consent, with the affordability test potentially re-run if loan size changes materially.

What happens to the loan when I die?

On the death of the last surviving borrower (or move into permanent care), the loan plus accrued interest becomes due. The estate has 12 months to repay, usually from the sale of the property. Beneficiaries can refinance or pay from other estate funds if they want to keep the home. With the NNEG, any shortfall on equity release is absorbed by the lender.

Will equity release reduce my children's inheritance?

Yes, materially. £100,000 at 6.5% compounds to £351,850 over 20 years — that is £351,850 less inheritance, all else equal. Mitigate with an inheritance protection guarantee (ring-fence 25%-50% of property value), voluntary partial repayments, or a smaller initial loan with a drawdown facility.

What are the alternatives?

Downsizing (no loan at all), drawing down existing pension wealth, family loans or gifts, standard interest-only mortgages (under 75), and government grants such as the Disabled Facilities Grant. Always exhaust cheaper alternatives before borrowing against your home for the rest of your life.
