EMI / Finance Calculator

Work out your monthly car payments. Typical UK used-car APR: 6–12%.

Car finance, decoded

Here is the number that actually decides most UK car purchases: not the £27,000 on the windscreen, but the figure that leaves your bank account on the first of every month. The vast majority of new cars in Britain are bought on finance — hire purchase or PCP — which means the monthly payment, the APR and the total amount payable matter far more than the headline price. The DrivePedia car finance calculator turns those three inputs into clarity: enter the car’s price, your deposit and the APR you have been offered, and it shows your monthly payment, the total you will pay, and exactly how much of that is interest.

Dealers love to negotiate on monthly payments because it hides the true cost of the deal — a longer term or a higher APR can quietly add thousands while the monthly figure barely moves. Running the numbers yourself before you walk in changes the dynamic completely. You will know what £2,700 down at 9.9% APR over four years should cost, so when the finance manager slides a quote across the desk, you can spot padding, compare lenders, and negotiate from knowledge instead of hope.

How this calculator works

Start by selecting your car — the calculator fills in its real on-the-road price automatically — or type any price manually for a used car or a negotiated deal. Then set three things: your deposit (as a percentage or a cash amount), the APR you have been quoted, and the term in months, from 12 up to 60. The calculator instantly shows your monthly payment, the total amount payable over the full term, and the total interest — the difference between what you pay and what the car costs. Adjust any slider and every figure recalculates live, so you can watch what an extra £1,000 deposit or a two-point APR rise does to your monthly outgoings before committing to anything.

Worked example

Take the Nissan Qashqai 2024 at £27,000. Put down a 10% deposit — £2,700 — leaving £24,300 to finance at 9.9% APR over 48 months. The calculator returns a monthly payment of £619.73. Over the full four years you will pay £29,747 in instalments, plus your deposit, making £32,447 in total — meaning roughly £5,447 of the deal is interest, the price of spreading the cost. For context, the database’s own standard HP illustration on the same car works out at £615.14 a month over 48 months — so if a dealer quotes you far above either figure, the rate has likely been marked up. Now the useful part: nudge the deposit to 20% (£5,400) and the monthly payment falls while the interest shrinks, because you are borrowing less. That single experiment, done in seconds, is worth more than an hour of haggling — it shows you precisely which lever to pull.

Frequently asked questions

What is APR and why does it matter so much?
APR — Annual Percentage Rate — is the yearly cost of borrowing expressed as a percentage, including interest and mandatory charges. A single point of APR on a £24,000 loan over four years is worth roughly £500. Dealers can mark up the APR above the lender’s base rate, so always ask what rate you are actually being offered and run it here first.
Should I choose HP or PCP finance?
With hire purchase (HP) you pay the whole car off and own it at the end; with PCP your monthly payments are lower but a large final “balloon” payment remains if you want to keep the car. This calculator models straightforward HP-style amortisation. For PCP, the maths differs — but the total-payable discipline still applies: never judge a deal on the monthly figure alone.
Does a bigger deposit always help?
Almost always. Every extra pound of deposit is a pound you are not borrowing at 9.9% APR, so it cuts both the monthly payment and the total interest. On the Qashqai example above, doubling the deposit from 10% to 20% saves hundreds in interest alone. The only reason to hold cash back is if you genuinely need the liquidity elsewhere.
Is this calculator a finance quote or an offer?
Neither — it is an illustration tool. It shows what a given price, deposit, APR and term would cost under standard amortisation, so you can compare deals and spot expensive ones. It is not a credit decision, and actual offers depend on your credit profile. Always read the lender’s own paperwork before signing anything.
Can I use it for a used car?
Yes. Just type the car’s price manually instead of picking from the database. Bear in mind that used-car finance often carries higher APRs than new-car deals, and older cars may not qualify for the longest terms — so enter the actual rate you have been quoted rather than assuming new-car figures will apply.

Estimate only — actual offers depend on credit status and lender terms.
