About Car Finance Calculator (UK — HP)
Work out the real monthly cost of a car on UK hire purchase before you visit the dealership. The default scenario — £18,000 financed at 9.9% over 4 years — is typical for UK HP finance; replace it with your quote to see the instalment, total interest and the year-wise payoff schedule. Knowing your number first is the strongest negotiating position at the finance desk. This models hire purchase (HP): you finance the full balance, own the car after the final payment, and the quoted APR amortizes on a reducing balance — unlike PCP, where a large balloon (the GMFV) is deferred and monthly payments cover mostly depreciation plus interest. If you're comparing a PCP quote, remember its lower monthly is not a lower cost: interest accrues on the balloon all term long. UK consumer-credit law gives HP borrowers voluntary-termination rights once half the total amount payable is paid, and lenders cannot repossess without court action once a third is paid — useful backstops if circumstances change. FCA rules also banned discretionary commission models that let brokers inflate APRs; still, always ask the dealer for the APR with zero commission flex and compare a personal-loan quote from your bank.

Frequently asked questions
What monthly payment should I expect on a £18,000 car loan?+
At 9.9% over 4 years the reducing-balance formula gives the instalment shown above, and lifetime interest equal to the "Total interest" figure. A shorter tenure or a bigger down payment cuts that interest directly — every unit of principal you avoid borrowing saves its compounded interest.
HP or PCP — which suits me?+
HP if you keep cars long: higher monthly, but you own it outright and pay less total interest. PCP if you swap every 2–3 years and want optionality: lower monthly, then either pay the balloon, refinance it, or hand the car back. Model the HP here and ask the dealer for the PCP's total amount payable to compare like-for-like.
What is voluntary termination on car finance?+
Under the Consumer Credit Act you may return the car and walk away once you've paid 50% of the total amount payable (including interest and fees) on HP/PCP, subject to fair-condition and mileage clauses. It's a statutory right, not a favour — check your agreement's 'half rule' figure before negotiating an early settlement.
Should I pick the longest tenure the lender offers?+
Only if cash flow forces it. Long tenures on a depreciating asset often leave you "underwater" — owing more than the car is worth in the middle years. If you must stretch the term, plan voluntary prepayments in the first half of the loan, when the interest component of each instalment is largest.
