What changes a £200,000 payment

Rate and term do most of the work. At 25 years, moving the rate by half a point changes the payment by about £58 a month up or £56 down. Shortening the term raises the payment but removes a lot of interest: 20 years at 4.5% is £1,265 a month and £103,672 in interest, against £1,013 and £164,813 over 30 years.

Where each payment goes

In the first year, £8,909 of your payments is interest and only £4,431 reduces the loan, so interest is 67% of what you pay. The principal part of the payment overtakes the interest part in month 116 (year 10). After 5 years you have repaid £24,284, which is 12.1% of the loan, and you still owe £175,716. Half the loan is gone by month 191.

Deposit and stamp duty on the home you are buying

A £200,000 mortgage is a loan, not a price. With a 20% deposit it buys a £250,000 home; a bigger deposit lowers the price you need to reach, a smaller one raises it. Stamp Duty Land Tax (England and Northern Ireland) is charged on the price, not the loan: on £250,000 it is £2,500 for a home mover, £0 for a first-time buyer and £15,000 for an additional property. The last column adds the deposit and the standard-rate stamp duty, the cash you need before costs such as legal fees. Rates checked 23 October 2026 on GOV.UK; Scotland and Wales have their own taxes.

Before you rely on these numbers

  • The 4.5% rate is an example. Rates change often and depend on your deposit, credit and lender, so use the rate on an actual quote.
  • Fees such as arrangement, valuation and legal costs are not included. When a fixed or discounted deal ends the rate changes, so re-run the calculator with the new rate and your remaining term.
  • This is general information, not a quote or financial advice.
