UK rates are fixed for 2 or 5 years, then revert to your lender's standard variable rate — often much higher. The Mortgage Ledger helps you understand your numbers in plain language, without selling you anything.

This calculator is provided for illustration purposes only and does not constitute financial advice, a mortgage offer, or a recommendation of any specific product or lender. The interest rate shown is a national average sourced from the Bank of England — your actual rate will depend on your personal circumstances, credit profile, deposit, and chosen lender, and is likely to differ from the figure shown here.

Stamp Duty/LBTT/LTT and Council Tax/Domestic Rates figures are estimates based on published national rates and averages at the time of writing; actual amounts depend on your local authority and the specific details of your purchase. Always confirm exact figures with HMRC, Revenue Scotland, the Welsh Revenue Authority, or your conveyancer before relying on them.

A UK repayment mortgage payment is principal and interest only — council tax and buildings insurance are separate bills, not part of the monthly figure the way US property tax is. Most UK buyers fix for two to five years and then remortgage. This calculator shows the monthly repayment for your rate, term, and deposit.

How this calculator works

The monthly repayment pays both interest and capital so the balance reaches zero over the term (typically 25–30 years). Interest-only mortgages, where you repay the capital separately, are now rare for residential buyers.

Unlike the US, council tax and buildings insurance aren't blended into the mortgage payment — they're billed separately — so the figure here is your pure mortgage cost.

Because UK deals are usually fixed for a short window, the payment shown is for your current rate; when the fix ends most borrowers remortgage rather than drift onto the lender's higher standard variable rate.

A worked example

A £300,000 home with a 25% deposit, 25-year term at a 6.5% example rate:

Deposit (25%)
£75,000
Loan amount
£225,000
Monthly repayment @ 6.5%
£1,519/mo
Council tax & insurance
billed separately

Stamp duty is a one-off cost at purchase, not part of the monthly payment — see the stamp duty calculator.

Who it's for

  • You're budgeting the monthly repayment before choosing a deal.
  • You want to compare terms and deposit sizes.
  • You're checking the cost of a specific fixed rate.

Frequently asked questions

What does a UK mortgage payment include?

Just capital and interest on a repayment mortgage. Council tax, buildings insurance, and any service charge are separate bills, not part of the monthly mortgage figure.

What mortgage term is normal in the UK?

25 to 30 years is typical. A longer term lowers the monthly payment but increases the total interest; a shorter term does the reverse.

Should I fix my rate?

Most UK borrowers take a two- to five-year fix for payment certainty, then remortgage. A tracker follows the base rate instead — cheaper when rates fall, riskier when they rise.

Is stamp duty part of the monthly payment?

No — stamp duty (SDLT/LBTT/LTT) is a one-off tax paid at purchase. Use the stamp duty calculator to work it out separately.
