UK mortgage repayment guide

Repayment vs interest-only

Repayment mortgages pay down capital and interest each month so the loan is cleared by term end. Interest-only mortgages pay only interest — you need a separate plan to repay the capital.

Most residential buyers use repayment. Interest-only is more common for buy-to-let with documented repayment vehicles.

UK-specific considerations

Deposit requirements typically start around 5–10% for residential purchases, with better rates at 15–25% deposit. Loan-to-value (LTV) bands affect the rate you are offered.

Use our stamp duty calculator for SDLT in England and Northern Ireland. Scotland uses LBTT and Wales uses LTT with different bands and reliefs.

  • Standard variable rate (SVR) and tracker products differ from fixed-rate deals.
  • Stress tests apply — lenders assess affordability at higher rates.
  • Arrangement fees can be added to the loan or paid upfront.

Frequently asked questions

?What are my mortgage repayments in the UK?
UK repayment mortgages combine principal and interest so the loan is fully paid off by the end of the term. Enter property price, deposit, rate, and term to see your monthly repayment in GBP.
?How much are repayments on a £250,000 mortgage?
On a £250,000 loan over 25 years at 5.5%, monthly repayment is roughly £1,535. Exact amounts depend on deposit, rate, and term — adjust the calculator for your scenario.
?What is the difference between repayment and interest-only?
Repayment mortgages pay off the loan by the end of the term. Interest-only mortgages pay only interest each month — the full balance is due at the end, usually via savings, sale, or remortgage.
?What rate is used on preset pages?
Scenario pages default to 5.5% unless you change the rate in the calculator.
?What is LTV?
Loan-to-value is your mortgage divided by property value. A £180,000 loan on a £200,000 home is 90% LTV.
?How long are typical UK mortgage terms?
25–30 year terms are common, though shorter terms reduce total interest paid.
