How does the car finance calculator work?
Thinking about a new set of wheels? Our car loan calculator can help you get an idea of what it might cost if you buy using a personal loan.
While it isn’t able to help with the costs for personal contract purchase (PCP) or hire purchase (HP), you can use it to work out your potential monthly repayments and how much much you might be able to borrow using a personal loan.
If you already know how much you'd like to borrow for a car
The calculator will give you an idea of your monthly payments, as well as showing the total interest you'll pay on your borrowing.
If you'd rather start with what's affordable to pay monthly
You'll be given an estimate of how much you could borrow, broken down into the loan amount and interest
Keep in mind that the actual amount you can borrow and rate you're offered when you apply depends on your financial situation and the lender's criteria.
How to use our car loan calculator
See how much you can borrow
-
1. Select ‘What can I borrow?’
2. Put in how much you can afford to repay every month
3. Choose how many years you'd like to pay back the car loan
4. Add in the APR (annual percentage rate) – if you have a poor credit score, you’ll typically have to pay a higher APR (more interest)
You can change the numbers – for example, the size of your monthly payment – to see how it affects what you can borrow or how much interest you’d pay.
See your monthly repayments
1. Choose ‘What are my repayments?’
2. Put in the amount you want to borrow
3. Decide how long you want to pay it back
4. Add in your APR
Want to play around with the numbers? Try shortening the loan term or stretching it out to see how it changes your payments. You can also look at the impact of a higher or lower interest rate.
When you’re weighing up different loan lengths, think about how long you’ll keep the car. You don't want to end up with a loan that you're still paying off after you've replaced it.
If you’re happy with one of the loans you’re likely to be eligible for, you can make a full application which will involve a hard credit check and show up on your credit record.
Remember: always double-check that you can comfortably manage the monthly repayments through to the end of the loan before applying.
You can check your credit score for free to help you get a more accurate idea of whether you're likely to be offered a competitive APR on your loan. Generally, the better your credit score, the lower the interest rate you'll pay.

What our expert says...
"A car finance calculator is often where affordability becomes real. Looking at the monthly payment across different car finance products over different repayment terms can make it easier to judge whether a deal still feels manageable over time."
