How our mortgage calculator works

A mortgage calculator can help you work out your monthly repayments or understand how much you could borrow. Our calculator estimates monthly repayments for a repayment mortgage using the standard amortisation formula.

A mortgage calculator should not replace a full affordability assessment or illustration from your lender — it should only be used for quick calculations and estimates.

Key assumptions

  • Interest is compounded monthly
  • The best available rate used by the calculator is assumed to apply for the full mortgage term
  • Results are estimates and do not replace a full affordability assessment

For example

If you're buying a property worth £335,000, put down a £50,000 deposit, and borrow over 30 years at a 4.26% interest rate:

  • Your monthly repayment is £1,404
  • You're borrowing £285,000
  • The total amount repayable over those 30 years is £505,332

What you can use this mortgage calculator for

  • Estimate your monthly repayments by inputting the purchase price (or outstanding balance for remortgage), deposit or equity, and term
  • Check if the repayments seem affordable before a full affordability check
  • Understand the total cost of borrowing, and how shortening and lengthening the term affects your monthly repayments and total amount payable

A mortgage calculator is less about giving an exact quote and more about helping you make the most informed decision before you speak with a lender or broker.

How changing the rate or term affects your mortgage

These examples assume borrowing £200,000 at 4.26% over 25 years.

Important: These examples are illustrative only and assume the interest rate stays the same for the full mortgage term.

This calculator provides an estimate based on the inputs you enter. Estimated rates may be generated using AI or static LTV bands — they are not mortgage offers, quotations, or recommendations. MortgageEasy offers regulated mortgage advice — your home may be repossessed if you do not keep up repayments on your mortgage. See our initial disclosures for more information.
