How Much Car Finance Can I Get?

Updated August 2026  ·  7 min read  ·  By MotifyMe®

There is no single figure. How much car finance you can get comes down to what you can comfortably afford, not just your salary. Lenders look at your income, your regular outgoings, any existing credit and your credit history to work out what you can realistically repay, and a bigger deposit or a longer term lowers the monthly payment. The sensible amount is the one that sits comfortably in your budget, not the maximum a lender will approve. Here is what shapes the number, and how to estimate it for yourself.

What decides how much you can borrow

Salary matters, but on its own it does not set your finance amount. Lenders assess affordability: your income minus your regular outgoings, so they can see what is genuinely left to cover a monthly payment. Two people on the same salary can be offered very different amounts depending on their commitments and credit history.

The main things a lender weighs up are:

The rough rule of thumb (and why it is only rough)

A common guide is to keep your total monthly car costs - finance plus running costs like insurance, fuel and tax - within roughly 15 to 20 percent of your take-home pay. Some people also use the idea that a car's price should sit somewhere around a third to a half of their annual salary. These are useful starting points, but they are only guides. The lender makes the actual decision based on your full circumstances, so treat any rule of thumb as a sense check, not a promise.

How your deposit and term change the picture

For any given monthly budget, two levers change how much car you can afford:

The calculator above lets you try different amounts, deposits and terms and watch the monthly payment change. That is the quickest way to work out what fits your budget before you enquire.

What if I am self-employed or have a thin credit file?

You can still be considered. Self-employed applicants are usually asked for proof of income such as accounts or bank statements, and a limited credit history is not an automatic no. Finance is available across a range of circumstances, though the amount and rate offered depend on the lender and your individual profile. Any credit assessment is carried out by the lender, with your consent.

Borrow what you can comfortably afford, not the maximum offered. The largest amount a lender will approve is not always the sensible amount to take. Leave room in your budget for insurance, servicing, fuel and the unexpected.

How to find out your figure

Use the calculator to see what different amounts would cost each month, then make a no-obligation finance enquiry. MotifyMe® introduces you to Presto Finance Ltd, who work with a panel of lenders. Their initial check is usually a soft search that does not affect your credit score, and a hard credit search is only ever run with your permission if you decide to go ahead.
