A mortgage is a loan secured against a property. The amount borrowed, interest rate, repayment method and term all affect payments and the total cost. Read the lender's illustration and offer carefully, and seek a suitably authorised mortgage adviser where you need help choosing a contract.

Understand the components

  • The loan amount is distinct from the property's purchase price and your deposit.
  • A repayment mortgage pays capital and interest over the agreed schedule.
  • An interest-only arrangement requires a separate, acceptable plan for repaying the capital.
  • Fees, introductory periods and early-repayment terms can change the overall comparison.

A calculator can illustrate payments from the numbers you enter, but it cannot assess the lender's full criteria or establish that the loan is affordable for you. Check how payments might change when an initial rate ends and keep other household costs in the budget.

Use MoneyHelper's mortgage information as a general starting point. Confirm specific terms with the lender or adviser and remember that failing to maintain secured-loan payments can put the home at risk.

Frequently asked questions

Is a mortgage calculator result a lender’s offer?

No. It is an illustration using the amount, rate and term entered. A lender makes its own affordability and property assessments and may offer different terms or no loan.

Does the monthly payment include every cost of buying?

Usually a repayment calculation covers the loan payment under its stated assumptions. Keep arrangement fees, conveyancing, surveys, purchase tax, insurance and removal costs separate unless the calculation explicitly includes them.
