A quick overview of mortgage repayments

When you take out a mortgage, you repay the debt over an agreed term length and are charged monthly interest over the course of the agreement. When your mortgage term has run its course, the loan amount will have been repaid and the property is yours outright.

You can read more about how this works in our guide to mortgage repayments.

Factors that determine your mortgage repayments

The amount you pay for your mortgage will depend on the following factors.

  • The interest rate you qualify for

  • The term length you agree with the lender

  • Product type, such as fixed rate or tracker

  • Repayment type, such as capital repayment or interest only

Mortgage repayment examples

A typical mortgage would be one taken out on a capital repayment basis with a 25 year term and a 4% interest rate. This table shows what the monthly mortgage repayments for different mortgage amounts would look like if taken out with these variables in place.

FAQs

Your first mortgage payment is often higher because it covers interest for a period longer than a standard month. It typically includes the interest accrued from the day your mortgage completed up to your first scheduled payment date, plus your regular monthly instalment. After this initial payment, your direct debit should settle to the agreed monthly amount.

THINK CAREFULLY BEFORE SECURING OTHER DEBTS AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON A MORTGAGE OR ANY OTHER DEBT SECURED ON IT.

IF YOU ARE THINKING OF CONSOLIDATING EXISTING BORROWING YOU SHOULD BE AWARE THAT YOU MAY BE EXTENDING THE TERMS OF THE DEBT AND INCREASING THE TOTAL AMOUNT YOU REPAY.
