Car Affordability Calculator UK – How Much Car Can You Really Afford?

Quick rule of thumb for UK car affordability

A simple guideline many UK drivers use is to keep car finance payments between 10% and 15% of your net (take-home) income, and only go towards 20% if you are comfortable prioritising the car over other spending. For example, if you take home £2,000 per month, a typical safe range for the finance payment alone is around £200–£300 per month.

The calculators on this site use those UK-style affordability percentages together with your income, deposit, term and APR to estimate a maximum monthly payment and car price. You can then adjust the inputs until the result fits comfortably within your budget.

What Is a Car Affordability Calculator?

A car affordability calculator estimates the price of a vehicle you can comfortably finance based on your: monthly income, existing financial commitments, deposit available, loan or finance term, and estimated interest rate.

The calculator then estimates: maximum monthly payment, recommended car price, total loan amount, and interest payable over time. This allows you to avoid over-borrowing and stay within a safe financial range.

Many car buyers only focus on the monthly payment offered by dealerships. However, without understanding the total cost, you may end up paying thousands more than necessary.

Why Car Affordability Matters

Car finance has become extremely common in the UK. In fact, over 90% of new cars are purchased using finance agreements such as PCP or HP.

While finance can make vehicles more accessible, it also means buyers can easily commit to payments that stretch their budget.

A car affordability calculation helps you avoid common mistakes such as: choosing a car that consumes too much of your monthly income; underestimating insurance and fuel costs; ignoring interest charges; and committing to long finance terms to reduce payments.

By calculating affordability first, you can choose a vehicle that fits comfortably within your financial situation.

How Much Car Can I Afford in the UK?

A commonly recommended guideline is that your total car expenses should not exceed 15% to 20% of your monthly take-home pay.

However, affordability also depends on: housing costs, existing loans, family expenses, fuel usage, and insurance costs. Our calculator considers these factors to help estimate a realistic vehicle budget rather than an overly optimistic one.

Understanding Car Finance in the UK

Before deciding how much car you can afford, it's important to understand the main types of car finance available in the UK.

Personal Contract Purchase (PCP)

PCP is one of the most popular forms of car finance. With PCP: you pay a deposit; make monthly payments for the finance term; and have a final optional balloon payment. At the end of the agreement you can: return the car; pay the balloon payment and keep the vehicle; or trade it in for another car. PCP often results in lower monthly payments, but the final balloon payment can be substantial.

Hire Purchase (HP)

Hire Purchase is simpler than PCP. With HP: you pay a deposit; make monthly payments; and own the car outright at the end. Monthly payments are typically higher than PCP, but there is no balloon payment at the end.

Personal Loans

Some buyers choose to take a bank loan or personal loan instead of dealership finance. Advantages include: full ownership of the vehicle immediately; no mileage limits; and freedom to sell the car whenever you want. However, interest rates may vary depending on your credit score.

Costs to Consider Beyond the Car Payment

When calculating car affordability, it's important to include the true cost of car ownership, not just the finance payment.

Insurance

Car insurance in the UK can range from around £500 per year for experienced drivers to £1,500+ for younger drivers. Insurance is often the second biggest car expense after finance.

Fuel or Charging

Fuel costs depend on mileage and fuel type. Typical estimates: petrol £120 – £250 per month; diesel £100 – £220 per month; electric charging £40 – £100 per month.

Vehicle Tax (VED)

Road tax varies depending on emissions and vehicle value. Typical range: £0 for some electric vehicles; £180+ per year for petrol/diesel cars.

Maintenance and Servicing

Cars require regular servicing and occasional repairs. Average estimates: servicing £200 – £400 annually; tyres £300 – £600 every few years; plus unexpected repairs. Including these costs ensures your affordability calculation reflects real ownership costs.

How Deposits Affect Car Affordability

A larger deposit significantly improves affordability. Benefits include: lower monthly payments, lower interest costs, and access to better finance rates. Typical deposits in the UK range from 10% to 20% of the car price.

Even a modest increase in deposit can reduce monthly payments substantially.

How Interest Rates Affect Affordability

Interest rates (APR) have a major impact on the total cost of car finance. Typical UK car finance rates include: 3% – 6% APR for excellent credit; 7% – 12% APR for average credit; 15%+ APR for poor credit.

Over a 5-year loan, the difference between 5% APR and 10% APR can add thousands of pounds to the cost of the car. Using a calculator allows you to see how interest affects: monthly payment, total interest paid, and overall affordability.

What Car Price Fits Your Budget?

Many buyers begin their search by browsing cars first and considering affordability later. A smarter approach is to: calculate a safe monthly payment; estimate your deposit; choose a finance term; and determine the vehicle price that fits that payment.

These figures vary depending on deposit, interest rate, and finance term.

Tips for Buying a Car You Can Comfortably Afford

Avoid Focusing Only on Monthly Payments

Dealerships may extend loan terms to reduce monthly payments, which increases interest costs. Always consider total repayment amount.

Compare Finance Offers

Interest rates vary widely between lenders. Compare offers from: dealership finance, banks, credit unions, and online lenders.

Consider Nearly New Vehicles

Cars lose a large portion of their value in the first few years. Buying a 2–3 year old vehicle can offer significant savings.

Factor in Running Costs

Fuel efficiency, insurance group, and servicing costs can dramatically affect affordability.
