Our Car Finance Calculator UK makes it easy to estimate your monthly repayments and the total cost of financing a vehicle.
The calculator also shows your loan-to-value ratio, total interest, total repayments and the overall amount paid for the vehicle.
Car finance allows buyers to spread the cost of a vehicle over several years rather than paying the full amount upfront.
HP agreements spread the cost over fixed monthly payments and ownership passes to you at the end.
PCP agreements typically have lower monthly payments but may include a balloon payment at the end.
Some buyers use a bank loan to finance their car purchase.
Hire Purchase (HP) is one of the most popular ways to finance a car in the UK. With HP finance, you typically pay a deposit followed by fixed monthly payments over an agreed period. Once all repayments have been made, ownership of the vehicle transfers to you.
Advantages of HP finance include:
However, monthly payments are usually higher than PCP finance because you are paying off the entire value of the car.
Personal Contract Purchase (PCP) is another popular option in the UK. PCP agreements generally have lower monthly payments because you are only financing the depreciation of the vehicle rather than its full value.
At the end of the agreement, you normally have three options:
PCP finance can be attractive for drivers who like changing cars every few years.
Some buyers choose to use a personal loan from a bank or building society to purchase a car. With a personal loan, you own the vehicle immediately and repay the loan over an agreed term.
Benefits include:
Personal loans can be a flexible alternative to dealer finance.
Putting down a larger deposit reduces the amount you need to borrow and may lower your monthly repayments.
Many buyers aim for a deposit of between 10% and 20% of the vehicle price.
A larger deposit may:
Interest rates play an important role in determining the overall cost of car finance.
Even a small difference in APR can significantly affect the amount paid over several years.
Higher interest rates generally mean:
Comparing finance offers carefully may save thousands of pounds over the life of an agreement.
APR (Annual Percentage Rate) represents the yearly cost of borrowing, including interest and certain lender charges where applicable. A lower APR generally means lower borrowing costs, although the overall amount paid also depends on the finance term, deposit and loan amount.
Loan-to-Value (LTV) compares the amount borrowed with the vehicle's purchase price. A lower LTV usually means lower financial risk and may improve your chances of receiving competitive finance offers.
For example, borrowing £20,000 for a £25,000 vehicle gives an LTV of 80%.
A balloon payment is a large optional payment due at the end of many PCP agreements. Choosing a higher balloon payment usually reduces your monthly repayments, although it increases the amount required if you decide to purchase the vehicle at the end of the agreement.
HP finance is often suitable for drivers who intend to keep their vehicle for many years. PCP finance may suit those who prefer changing cars regularly and want lower monthly payments.

Increasing the deposit and reducing the term may lower the overall interest paid.
Requirements vary between lenders, but stronger credit histories may improve approval chances and result in lower interest rates.
Many agreements allow early repayment, although fees or settlement charges may apply.
PCP often offers lower monthly payments, but HP may cost less overall if you intend to keep the car.
A deposit of 10% to 20% is common, although larger deposits can reduce borrowing costs.
Yes. Increasing your deposit reduces the amount borrowed, which usually lowers both your monthly repayments and the total interest paid over the agreement.
Some lenders specialise in bad credit car finance, although interest rates may be higher.
Many buyers focus only on the monthly repayment, but the total amount paid over the finance agreement is often a better measure of affordability. Comparing total borrowing costs can help you choose between different finance offers.
