Mortgage Calculator UK

Use our Mortgage Repayment Calculator to estimate your monthly repayments and the total cost of borrowing. Whether you are buying your first home, moving, or remortgaging, this simple tool gives you a clear starting point.

Mortgage Repayment Calculator

If you’re trying to get your head around what a mortgage might cost each month, this tool gives you a quick, realistic idea. It’s a repayment mortgage calculator, so the monthly figure includes both the part that reduces your balance and the interest charged by the lender.

If you’re more focused on how much you can actually borrow, you might find our Affordability Calculator useful too. A lot of people check both tools before speaking to us.

Just enter the loan amount, the interest rate, and the term. The results update straight away so you can see the monthly repayment and the total interest over the whole mortgage. It’s a simple way to check whether a deal feels affordable before you go any further.

If you want a more accurate picture for your own situation, our advisers can compare real deals from across the market. The service is fee-free and we do all the heavy lifting for you.

IMPORTANT This information is generated by a computer and is based on many assumptions. It should be used as a rough guide to calculate general figures to help give you a rough idea. If you want a more accurate figure, obtain an exact calculation from your lender or broker before making any decisions. We hold no responsibility for any potential errors that may occur in the figures presented.

How to Use This Calculator

You only need three things:

Loan amount: the amount you want to borrow
Interest rate: the rate you’re expecting or have been offered
Mortgage term: how long you want the mortgage to run

Once you fill those in, the calculator shows:

your monthly repayment
the total interest over the term

If you’re just exploring options, it’s a great place to start.

Frequently Asked Questions

How do repayment mortgages work?

A repayment mortgage means you pay back a mix of interest and capital each month. As time goes on, more of your payment reduces the balance. By the end of the term, the whole mortgage is cleared. The calculator shows you roughly how this plays out over the years.

Why does the amount change when I adjust the rate or term?

Because both have a big impact. A lower rate reduces the monthly payment. A longer term spreads the cost out but increases the total interest. A shorter term does the opposite. The calculator helps you see these differences instantly.

Is this calculator accurate enough to plan with?

It’s a solid guide, but not a full lender quotation. Lenders include fees, product types, and affordability checks that can affect the final figure. Use the calculator to explore options, then get a personalised illustration before making a decision.

Can this be used for remortgaging?

Yes. Just enter the amount you still owe and adjust the rate and term. Many people use this tool to compare their current mortgage with what’s available elsewhere.

Do repayment mortgages always cost more each month than interest-only?

Usually yes, because you’re paying down the balance as well as the interest. Some people prefer repayment because you finish the term owing nothing. If you’re unsure what’s right for you, we can talk you through both options.

Can a broker help me get a lower repayment?

Sometimes. We can look at lower-rate lenders, check your eligibility with different banks, and help you compare product fees that might affect the monthly cost. Our service is fee-free, so it doesn’t cost anything to see what your options are.
