Deposit Impact Calculator
Wondering how much deposit to put down? This calculator shows your monthly payment and total interest at four deposit levels — 0%, 10%, 20%, and 30% — so you can see exactly how your deposit affects the cost of finance.
Frequently asked questions
How much deposit should I put down on a car?
There is no fixed rule, but 10–20% is typical in the UK. A larger deposit reduces monthly payments and total interest. However, tying up too much cash in a depreciating asset may not be wise — consider whether the money could earn more elsewhere.
Can I get car finance with no deposit?
Yes, many lenders offer 0% deposit car finance. However, your monthly payments and total interest will be higher, and you may need a stronger credit score to qualify. Some PCP deals include manufacturer deposit contributions to reduce the upfront cost.
Does a bigger deposit affect my APR?
Potentially. A larger deposit reduces the lender's risk (lower loan-to-value ratio), which may qualify you for a lower APR. However, the representative APR advertised is available to at least 51% of applicants regardless of deposit.
What is a deposit contribution?
A deposit contribution (or manufacturer contribution) is a discount offered by the car manufacturer, applied as part of your deposit. It reduces the amount you need to finance. Always check whether a cash discount is available instead, which may save more overall.
