How to calculate what I can afford to spend on my car? 💸

Our Hire Purchase calculator can help you understand the amount you’d have to pay monthly, but this won't tell you how much you can afford to spend. You'll also need to think about your monthly affordability before committing to a finance agreement. 

Using our ‘Affordability Calculator’ below you can find out how much car finance you can afford by following a few simple steps.

Hit calculate to see your estimated monthly disposable income


Now that you know what you can afford, use our car finance calculator to see how much you can spend on your car

The use of this Affordability Calculator to determine your disposable income is not a guarantee of the availability of credit facilities from Carmoola

Step 1: Your monthly income

How much do you earn each month? Is it a regular amount? If not, try to average out the past 6 months.

Step 2: Your monthly outgoings

How much do you spend each month? This amount should be your individual monthly spending on the following:

  • Housing (i.e. rent or mortgage)
  • Utilities and other bills (i.e. council tax, gas, electricity, water, home insurance, broadband, TV, mobile phone)
  • Food
  • Childcare
  • Commuting and car costs (i.e. commuting costs, car insurance, MOT, servicing, road tax)
  • Your monthly credit commitments (i.e. loans, credit cards)

Step 3: Calculate your monthly disposable income

Now you've got your monthly income and monthly spend, you can deduct the spend
from the income to see roughly what your monthly disposable income might be. For example, if you earn £1,500 per month, and you spend £1,000 per month, your disposable income would be £500.

When calculating your disposable income, you should always allow yourself a little buffer for any unplanned events or activities to ensure that you’ll be able to afford your monthly car loan repayments.

Step 4: Investigate your credit history

There's loads of free tools out there where you can find out more about your credit score. Credit Karma and ClearScore are great free options, as they also give you cool tips on how to improve your credit score! If you're not familiar, you can start to get up close and personal with your score, and this could help you understand what sort of rate you might be offered by car finance companies.

Step 5: Calculator time!

Now you have a clear understanding of your disposable income and credit score, the next step is using our hire purchase car finance calculator to better understand how much you want to borrow, and how much it might cost to finance a used car. Don't forget, you may have some savings or an old car to part-exchange as part of the purchase.

FAQs About Calculating Car Finance

Check below for the answers to some of our most frequently asked questions, related to our Hire Purchase car finance calculator. Got more questions? Check out our FAQs page 👍

How does the car finance calculator work?

Our calculator uses a number of variables to work out your result including the amount you’d like to spend on your car, the length of the agreement and the APR applied to the car finance. It uses these figures to help illustrate an example of what monthly repayments on this loan example might be.

How are interest rates calculated?

Each lender has specific criteria that looks at your individual financial circumstances and calculates the interest rate based on these details. Car finance rates usually range between 6% and 30% APR. Car loan rates are subject to change.

What is a good APR for car finance?

Car finance lenders determine the APR they can offer you, based on your individual credit profile. A good APR for one person, may be a terrible APR for another! To find out what APR you would get, why not answer a few quick questions on Carmoola? We only run a soft credit search when you do this, so there's no impact on your credit score just to find out.

Does deposit make a difference in my monthly payments?

Yes! Here's an example to help you understand how it works. Let's say you're buying a car that costs £10,000. Some lenders such as Carmoola will be able to help you borrow the whole £10,000 if you want to. However, if you decide to add a small deposit, let's say £2,000, then you'd only need to borrow £8,000 to buy the car. Borrowing less, means your monthly payments will be less, and you'll pay less interest overall.

Are interest rates fixed?

When you take out a Hire Purchase car finance agreement, your APR is set at the beginning and is fixed throughout the term you choose.
