How to use the online car finance calculator
Four inputs. Thirty seconds. Instant results. Our car finance calculator strips away the guesswork and shows your estimated monthly payments across both HP and PCP — before you speak to anyone.
Enter how much you want to borrow. Type in the amount you need, anywhere between £3,000 and £50,000. This is the total car loan you're looking to take out, not the price of the car itself.
Add your deposit. Put in your deposit amount: between £100 and £10,000. A larger deposit reduces your finance amount, which directly lowers your monthly repayments.
Select your credit rating. Choose from the dropdown: Excellent through to Poor. Your credit score shapes the APR a lender is likely to offer you, so pick the option that honestly reflects your situation.
Choose your loan term. Pick 24, 36, 48, or 60 monthly instalments. Longer terms spread the cost further, but you'll pay more interest overall, the calculator shows you both sides instantly.
Hit "Get car finance quote" and compare. Results appear side by side for hire purchase and personal contract purchase. You'll see the monthly payment, interest rate, amount of interest, and total amount repayable for each so you can choose the right type of finance with confidence.
Explaining credit scores and the car finance calculator
Your credit score determines what car finance options are available to you. Banks and lenders use it to judge how reliably you'll repay a car loan and it directly affects the APR, your monthly repayments, and the total cost of car finance.
The calculator can help you understand the relationship between your credit rating and your monthly payment. Select your credit rating in the tool and the calculator gives you an instant estimate so you can see how a poor credit score affects what you'll pay before you apply.
Several scoring systems exist across the UK, but most lenders rate borrowers along the same broad scale. Here's what each band typically means:
- Excellent — extensive credit history, no missed payments, no outstanding convictions, and no past credit denials. You'll access the lowest interest rates and the strongest car finance options.
- Good — very few missed payments and rare loan denials. Lenders will offer competitive rates, though not always the lowest available.
- Fair — some missed payments or a credit limit breach in your history. Expect fewer choices and higher interest rates than those with a stronger profile.
- Poor — past loans taken at high interest, significant missed payments, or a history of credit difficulties. Financing a car remains possible, but lenders will price the risk into your APR.
- Bad — multiple missed payments, defaults, or past financial difficulties such as bankruptcy. We still offer bad credit car finance, find out how much you could borrow using our calculator.
How does a car finance calculator work?
Enter your numbers and get your monthly picture instantly. Use our car finance calculator to estimate your regular monthly payments based on how much you want to borrow, your deposit, your credit rating, and your chosen loan period.
The calculator will allow you to compare two of the most popular car finance options side by side: hire purchase finance and PCP finance. Both are distinct products, and the numbers they produce look very different.
Hire purchase (HP) spreads the full cost of a car across fixed regular monthly payments. The finance is secured against the car throughout the agreement. You don't own the car outright until you make the final payment but once you do, it's yours with nothing left to settle.
Personal contract purchase (PCP) keeps your monthly payments lower by deferring a large portion of the cost to the end of the agreement. That deferred amount is the balloon payment. At that point, you choose to pay the balloon payment and buy the car, hand it back, or use the value of the car as a deposit on your next car.
The annual percentage rate (APR) runs through every calculation. A lower APR reduces the total cost of a car over the loan length. A higher APR increases it. The calculator to find the right balance is right here, and the figures it produces reflect your specific inputs, not a generic estimate.

FAQ
Can our car finance calculator help if you have bad credit?
Yes, select your credit rating in the calculator to see what your monthly repayments could look like. We offer bad credit car finance, and a poor credit score doesn't automatically disqualify you. Lenders on our panel consider your full financial picture, not just your credit history.
How much can I borrow to buy a car?
You can borrow between £3,000 and £50,000 through our calculator. The amount a lender approves depends on your credit score, income, and the deposit you put down. Use our car finance calculator to find a borrowing figure that fits your budget.
How much will my monthly car loan repayments be?
That depends on how much you borrow, your APR, and your loan term. Use the finance calculator to estimate monthly costs across both HP and PCP, adjust the loan period and deposit to see how each change affects what you pay each month.
How are interest rates calculated?
Lenders set your interest rate based on your credit score, the loan amount, and the loan term. The annual percentage rate reflects the true yearly cost of borrowing, including fees. A stronger credit profile consistently unlocks lower rates.
What is a good APR for car finance?
A good APR sits between 9% and 12% for most borrowers in the UK. Your actual rate depends on your credit score and which lender matches your application. Applying with a deposit reduces the finance amount and can improve the rate you're offered.
Does paying a deposit make a difference to my monthly payments?
Yes, a larger deposit reduces the amount you need to borrow, which directly lowers your regular monthly payments. It can also reduce the total amount of interest you pay across the full finance agreement. Even a modest deposit makes a measurable difference.
Are car finance interest rates fixed?
Yes, for both HP and PCP the interest rate is fixed at the start of your finance agreement. Your monthly payment stays the same for the entire loan period, so you can budget with certainty from day one.
What length of loan is right for you?
The right loan period balances affordable monthly repayments against the total amount you repay overall. A longer loan reduces what you pay each month but you'll pay more interest across the full term. Use the calculator to see how 24, 36, 48, and 60 monthly instalments each affect your costs, then choose the loan length that fits your budget without overextending it.
What costs should I think about?
Start with the obvious ones: your deposit, monthly repayments, and APR. But factor in the full picture too: car tax, car MOT, insurance, and fuel all add to the monthly cost of running the car you choose. On a PCP agreement, decide early whether you plan to pay the balloon payment at the end or hand the car back, that decision shapes which finance product makes more sense from the outset.
