Whether you're saving for a house deposit, dream holiday, emergency fund, or retirement, having a clear savings goal and plan dramatically increases your chances of success. Studies show people with specific financial goals save more than those without clear targets.
This guide explains how to calculate your monthly savings requirements, choose the right savings accounts, and use compound interest to reach your goals faster.
Basic Savings Calculation
The fundamental savings calculation is straightforward:
Savings Goal ÷ Number of Months = Monthly Savings
Example: £15,000 deposit in 3 years
£15,000 ÷ 36 months = £417 per month

The Power of Compound Interest
Earning interest on your savings—and then interest on that interest—accelerates your progress. The earlier you start, the more compound interest works in your favour.

Use Savings CalculatorISA Allowance for 2025/26
Individual Savings Accounts (ISAs) are the cornerstone of tax-efficient saving in the UK. For the 2025/26 tax year (6 April 2025 to 5 April 2026), the ISA allowance remains at £20,000 per person. This means you can save up to £20,000 across all your ISA accounts without paying tax on the interest earned.
The £20,000 annual allowance can be split across the following ISA types:
- Cash ISA: The simplest option. Your savings earn interest completely free of Income Tax. Interest rates vary, with the best easy-access Cash ISAs currently offering 4-5% AER. Fixed-rate Cash ISAs may offer slightly higher rates for locking your money away for 1-5 years.
- Stocks and Shares ISA: Invest in funds, shares, and bonds. Returns are not guaranteed but historically deliver higher long-term growth than cash savings. Any capital gains and dividends within the ISA are completely tax-free.
- Innovative Finance ISA: Allows you to hold peer-to-peer loans within a tax-free wrapper. Higher potential returns but also higher risk, as these investments are not protected by the FSCS.
- Lifetime ISA (LISA): Available if you are aged 18-39. You can save up to £4,000 per year (which counts towards your £20,000 ISA limit), and the government adds a 25% bonus on top of your contributions.
Remember that any unused ISA allowance does not carry over to the next tax year. If you do not use your full £20,000 by 5 April, that allowance is lost permanently.
The Power of Compound Interest
Compound interest is the single most powerful force in long-term savings. It means you earn interest not only on your original deposit but also on the interest that has already been added. Here are examples showing the impact of compound interest on UK savings:
- £200/month at 4% for 5 years: You contribute £12,000 in total. With compound interest, your savings grow to approximately £13,260 -- earning £1,260 in interest.
- £200/month at 4% for 10 years: You contribute £24,000 in total. With compound interest, your savings grow to approximately £29,500 -- earning £5,500 in interest.
- £200/month at 4% for 20 years: You contribute £48,000 in total. With compound interest, your savings grow to approximately £73,300 -- earning £25,300 in interest.
- £200/month at 4% for 30 years: You contribute £72,000 in total. With compound interest, your savings grow to approximately £138,900 -- earning £66,900 in interest.
The key takeaway is that time is the most important factor. The interest earned in years 20-30 is dramatically more than in years 1-10, because your accumulated interest itself earns interest. Starting to save even small amounts as early as possible maximises the benefit of compounding.
Regular Saver Accounts
Regular saver accounts are a popular option for UK savers who want to build a savings habit. These accounts typically require a fixed monthly deposit and offer higher interest rates than standard savings accounts, though they come with restrictions:
- How they work: You commit to depositing a set amount each month, usually between £25 and £250. In return, the bank offers a premium interest rate for the first 12 months.
- Current top rates: The best regular saver accounts in the UK offer 6-8% AER, significantly above standard savings rates. However, because you build up the balance gradually, the effective return on your total deposits is roughly half the headline rate.
- Examples: First Direct Regular Saver, Nationwide Regular Saver, and HSBC Regular Saver are consistently among the best options. Most require you to hold a current account with the same bank.
- After 12 months: The account typically reverts to a standard easy-access rate. At this point, you can transfer the balance to a higher-paying account or ISA and open a new regular saver for another year.
Regular saver accounts are particularly effective for building an emergency fund or saving towards a specific goal within a 12-month timeframe.
Lifetime ISA (LISA) for First-Time Buyers and Retirement
The Lifetime ISA is one of the most generous savings incentives available to young UK savers. Here is how it works:
- Eligibility: You must be aged 18 to 39 to open a LISA. You can continue contributing until you turn 50.
- Contribution limit: Up to £4,000 per tax year. The government adds a 25% bonus, meaning you receive up to £1,000 in free money each year.
- First home purchase: You can use your LISA savings to buy your first home worth up to £450,000. The bonus is applied to your purchase.
- Retirement: After age 60, you can withdraw all funds (including the bonus) completely tax-free.
- Early withdrawal penalty: If you withdraw for any reason other than buying a first home or after age 60, you lose 25% of the amount withdrawn. This effectively means you lose the government bonus plus a portion of your own contributions.
Over 20 years, a LISA with maximum annual contributions of £4,000 plus the £1,000 government bonus at 4% interest could grow to approximately £150,000, making it one of the most effective long-term savings vehicles for eligible UK savers.
Frequently Asked Questions
How much should I have saved by age 30 in the UK?
Financial advisers commonly suggest having the equivalent of one year's salary saved by age 30. For the UK median salary of approximately £34,000, this would mean having £34,000 in savings and investments. However, many UK adults fall short of this target. A more practical starting point is to build an emergency fund covering 3-6 months of essential expenses (typically £5,000-10,000), then focus on longer-term saving and investing.
Are my savings protected if my bank fails?
Yes, the Financial Services Compensation Scheme (FSCS) protects up to £85,000 per person, per authorised financial institution. If you have more than £85,000, spread your savings across multiple banks or building societies to ensure full protection. Note that some banking brands share the same banking licence (for example, Halifax and Bank of Scotland are both under Lloyds Banking Group), so check that your banks are separately authorised.
Should I save in a Cash ISA or a regular savings account?
This depends on whether you have used your Personal Savings Allowance (PSA). Basic rate taxpayers can earn up to £1,000 in savings interest tax-free through the PSA, while higher rate taxpayers get £500. If your interest earnings are within these limits, a regular savings account with a higher headline rate may be more beneficial than a Cash ISA. However, if you are a higher earner or have substantial savings, a Cash ISA provides permanent tax-free growth with no annual limit on interest earned within the wrapper.
What is the best way to save for a house deposit in the UK?
For first-time buyers aged 18-39, a Lifetime ISA offers the best returns thanks to the 25% government bonus. Combine this with a high-interest regular saver account and a Cash ISA for amounts above the £4,000 LISA limit. A realistic target for most first-time buyers is saving 5-10% of the property price as a deposit, though a 15-20% deposit unlocks significantly better mortgage rates.
Saving Money in the UK: Rates, Accounts, and Government Schemes
The UK savings market has undergone significant changes in recent years, with the Bank of England base rate rising from historic lows of 0.1 percent in 2021 to over 5 percent by late 2023, before stabilising. This has created much more attractive savings rates for UK savers, with easy-access accounts offering 4 to 5 percent and fixed-term bonds offering up to 5.5 percent from competitive providers. UK households collectively hold over 1.9 trillion pounds in savings deposits, according to Bank of England data.
Individual Savings Accounts (ISAs) remain one of the most important savings vehicles for UK residents. The annual ISA allowance is currently 20,000 pounds per person, within which all interest earned is completely tax-free. This is particularly valuable for higher-rate and additional-rate taxpayers, who would otherwise pay 40 percent or 45 percent tax on savings interest above their Personal Savings Allowance (500 pounds for higher-rate, zero for additional-rate taxpayers). Types of ISAs include Cash ISAs, Stocks and Shares ISAs, Innovative Finance ISAs, and the Lifetime ISA for first-time buyers and retirement saving.
The UK government's Premium Bonds, offered through National Savings & Investments (NS&I), are the nation's most popular savings product with over 24 million holders. Rather than paying a fixed interest rate, Premium Bonds enter each pound saved into a monthly prize draw with a current prize fund rate of 4 to 4.5 percent. The maximum holding is 50,000 pounds per person, and all prizes (ranging from 25 pounds to 1 million pounds) are tax-free. While the expected return is comparable to a savings account, the actual return depends on luck, and some savers will earn significantly above or below the published rate.
For children's savings, the Junior ISA (JISA) allows parents to save up to 9,000 pounds per tax year per child, with all returns tax-free. The money is locked until the child turns 18 but can be invested in cash or stocks and shares. Regular saving from birth at 100 pounds per month into a well-performing stocks and shares JISA could grow to over 25,000 pounds by the child's 18th birthday.
Practical Savings Tips for UK Residents
- Use your full ISA allowance first: Before putting money into standard savings accounts, maximise your 20,000-pound annual ISA allowance to ensure interest is earned completely tax-free. This is especially important if you are a higher-rate taxpayer with a reduced Personal Savings Allowance of just 500 pounds.
- Set up a regular saver account: Many UK high street banks offer regular saver accounts with elevated interest rates (sometimes 6 to 8 percent) in exchange for depositing a fixed amount each month, typically between 25 and 250 pounds. These are excellent for building a savings habit alongside a competitive return.
- Automate your savings: Set up a standing order to transfer money into your savings account on the same day you receive your salary. Treating savings as a fixed expense rather than saving whatever is left over at the end of the month consistently produces better results.
- Build a three-to-six-month emergency fund: UK financial advisers recommend maintaining an emergency fund covering three to six months of essential expenses in an easily accessible account before saving toward longer-term goals.
