How does the loan repayment calculator work?

Our bank loan calculator helps you estimate either your monthly loan repayments or how much you could borrow, depending on what you'd like to work out.

If you know how much you’d like to borrow

Add the details and you'll be shown your potential monthly repayments, along with the loan amount and total interest you could pay over the loan term

If you’d rather start with what you can afford each month

The calculator will figure out how much you might be able to borrow and also break this down into a loan amount and interest payments.

Play around with the numbers to see how changes such as a shorter loan term or lower interest rate could affect your repayments or interest paid.

Bear in mind...

These results are estimates only. The amount you can borrow and the rate you’re offered will depend on the lender and your personal circumstances.

Using the calculator to see your potential repayments

Choose ‘How much will my repayments be?’

Put in the amount you want to borrow

Set the loan term

That’s the length of time you plan to replay the loan over

Put in the APR

This is the ‘annual percentage rate’, which is the interest plus any fees. If you have a poor credit rating, you’re more likely to be offered a higher APR

Using the calculator to see what you could borrow

Choose ‘How much could I borrow?’

Enter the amount you can realistically afford to repay each month

Input the loan term

That’s how long you’ll take to repay the loan

Set the APR

This is the ‘annual percentage rate’, which includes the interest plus any fees

What factors affect the size of the loan repayment?

When looking for a personal loan, it’s important to compare your options to make sure you don’t pay more than you need to. Here’s what to consider:

Did you know?

When a loan is advertised, the representative APR tells you how much it would cost 51% or more of successful applicants to borrow that amount of money for the specified period. But the rate that you're offered could be higher or lower depending on your credit rating.

How can I cut the cost of a loan?

Repay early

You can usually pay off a loan early to save on interest, although the lender can charge you an early repayment fee. Your loan agreement will detail any early repayment charges.

Make extra payments (overpay)

Overpaying your bank loan could reduce your interest payments. By law, you can make full or partial overpayments of up to £8,000 per year without being charged a fee.

Switch loan providers

Switching an unsecured loan to one with a lower interest rate could save you money. But check that the amount you’ll save in interest is more than the early repayment charge.
