How does our repayment tool calculate mortgage payments?

Results should only be used as a guide. To get a better idea about repayments, use our mortgage finder to see the repayments against actual mortgage deals.

What is a mortgage repayment?

A mortgage repayment is the regular payment made by you (the borrower) to the mortgage provider (lender) to repay the money you borrowed. This includes any interest charges and fees.

You and the lender will work out how much you’ll pay each month when you take out your mortgage as well as when you will make payments each month.

How do mortgage interest rates work?

When you take out a mortgage or loan, the lender charges you interest on the amount you borrow. This interest is a percentage of your loan amount and adds to your monthly mortgage payments.

If your mortgage interest changes, so will your repayments. Use our calculator to check how any change may affect your monthly costs by inputting different interest rate values. Once you've found a repayment amount you're comfortable with, use our rate finder to see what mortgages are available.

What are mortgage repayments made up of?

Mortgage repayments are a combination of two key parts: capital and interest.

Capital: This refers to the actual amount of money you borrow. Each repayment chips away at this borrowing amount, bringing you closer to owning your home outright.

Early on in your mortgage journey, a larger portion of your payment goes towards interest, with a smaller amount reducing the capital. As you near the end of your term, this flips, with most of your payment going towards capital repayment.

Interest: This is the fee you pay to the lender for borrowing their money. The interest rate is typically expressed as an annual percentage rate (APR), and it's applied to the remaining balance of your loan each month.

So, the more you owe, the more interest you'll accrue. Remember, interest adds up over time, so making additional payments towards your borrowed amount can significantly reduce the overall interest you pay.

It's important to note that some mortgages, like interest-only mortgages, only cover the interest portion in the monthly payments. With these types of mortgages, you'll need to have a separate plan in place to repay the original loan amount at the end of the term.

Does using the mortgage repayment calculator affect your credit score?

No, using our mortgage repayment calculator will not affect your credit score in any way. These calculators are simply tools that estimate your monthly payments based on factors like mortgage amount, interest rate, and loan term.

They don't access your credit report or leave any inquiries that lenders can see. So, feel free to play around with different scenarios and interest rates without worrying about any negative impact on your creditworthiness.

Our Mortgage Affordability calculator will search through a pool of over 50 lenders to find an estimate of your mortgage affordability. No credit checks required.

Your monthly payments could be £1,754
