Starter & First-Time Buyer Mortgages (£50K - £175K)

Mortgage payment calculators for smaller loans, ideal for first-time buyers, shared ownership schemes, or properties outside major cities. These amounts often qualify for first-time buyer stamp duty relief.

Mid-Range Mortgages (£200K - £300K)

The most common UK mortgage range, covering the average UK house price. These calculators are ideal for typical family homes and help you compare costs across different interest rates and terms.

How Are Monthly Mortgage Payments Calculated?

UK mortgage repayments are calculated using the standard annuity formula, which takes into account the loan amount, interest rate, and term length. Here is an example for common mortgage amounts at 4.5% interest over 25 years:

Mortgage AmountMonthly PaymentTotal InterestTotal Repaid
£150,000£834£100,169£250,169
£200,000£1,111£133,559£333,559
£250,000£1,389£166,949£416,949
£300,000£1,667£200,339£500,339
£500,000£2,779£333,898£833,898

Note: These figures assume a repayment mortgage at 4.5% fixed rate over 25 years. Your actual payments will vary depending on your specific interest rate, term, and whether you choose repayment or interest-only.

Upper Mid-Range Mortgages (£350K - £500K)

Mortgage calculators for higher-value properties, common in London commuter towns, larger family homes, and regional city centres. Stamp duty becomes a significant factor at these levels.

High-Value Mortgages (£550K - £1M)

Payment calculators for premium properties and London homes. At these levels, mortgage affordability assessments are stricter, and many lenders require larger deposits. Higher stamp duty rates also apply.

How Interest Rates Affect Your Monthly Payments

Even a small change in interest rate can significantly impact your monthly mortgage payments and total cost. Here is how rates affect a £250,000 mortgage over 25 years:

Interest RateMonthly PaymentTotal InterestDifference vs 4%
3.5%£1,252£125,537-£28,575
4.0%£1,319£145,734
4.5%£1,389£166,949+£21,215
5.0%£1,461£189,115+£43,381
5.5%£1,535£212,154+£66,420
6.0%£1,611£235,989+£90,255

Key takeaway: A 1% increase in interest rate on a £250,000 mortgage adds roughly £130-£150 to your monthly payment and £40,000-£45,000 in total interest over 25 years.

Mortgage Payment FAQs

How much are the monthly payments on a £200,000 mortgage?

Monthly payments on a £200,000 mortgage depend on the interest rate and term. At 4.5% over 25 years, you would pay approximately £1,111 per month, totalling £333,559 over the full term. At 5.5% over the same period, payments rise to around £1,228 per month. Extending the term to 30 years at 4.5% reduces the monthly payment to roughly £1,013 but increases total interest paid.

What is the difference between a repayment and interest-only mortgage?

With a repayment (capital and interest) mortgage, your monthly payments cover both the interest charge and a portion of the loan balance, so the mortgage is fully repaid at the end of the term. With an interest-only mortgage, you only pay the interest each month, meaning the full loan amount remains outstanding at the end. Interest-only payments are significantly lower, but you need a separate plan to repay the capital.

How much deposit do I need for a UK mortgage?

Most UK lenders require a minimum deposit of 5-10% of the property value. A larger deposit of 15-25% typically gives you access to significantly better interest rates. For example, on a £300,000 property, a 10% deposit would be £30,000, meaning you would need a £270,000 mortgage. Government schemes such as Help to Buy and shared ownership can help with smaller deposits.

How does the mortgage term affect monthly payments?

A longer mortgage term reduces your monthly payments but increases the total amount of interest you pay. For example, a £300,000 mortgage at 5% costs approximately £1,754 per month over 25 years with £226,125 total interest. Over 30 years, the monthly payment drops to around £1,610 but total interest rises to £279,767. That is an extra £53,642 in interest for the benefit of lower monthly payments.
