Car Affordability Calculator
Estimate how much car you can afford based on income, running costs, down payment, and loan terms.

Protect room for running costs before calculating the loan
The calculator first limits total monthly car cost as a share of take-home income, then removes insurance, fuel or charging, maintenance, tax, parking, and other running costs. Only the remainder supports a loan payment. This order prevents a lender-approved instalment from consuming the money needed to keep the car on the road.
Use realistic costs for the specific model and your driving. An older cheap car may need more repairs; a newer financed car may require comprehensive insurance and lose value quickly. Keep some down-payment cash back for registration, immediate maintenance, tyres, and an emergency reserve rather than putting every available euro into the purchase.
A real-world check
A €300 car budget does not mean a €300 loan payment
If insurance, fuel, parking, and maintenance average €190 a month, only €110 remains for finance. Ignoring running costs could approve a much larger loan on paper and leave the owner short every month the car is actually used.
How to read the result
Little room for a loan
Running costs already use most of the target. Consider a lower price, cash purchase, different model, or transport alternative.
A high maximum price
Treat it as a ceiling, not a shopping target. Buying below it preserves flexibility and reduces depreciation exposure.
A long term raises the price
The payment falls, but interest and the risk of owing more than the car is worth can increase.
What this calculator cannot know
- The result excludes dealer fees, taxes, depreciation, repairs, changing fuel prices, loan fees, and differences in insurance coverage.
- Trade-in estimates can change after inspection, and the old loan balance must be settled before treating all trade-in value as equity.
What to do next
- Get insurance quotes and a realistic annual maintenance estimate for the exact model.
- Compare total loan cost and vehicle price separately from the monthly payment.
- Keep a repair reserve after the down payment and first ownership costs.

Common questions
About this calculator
Should insurance and fuel count in affordability?
Yes. The payment is only one part of car cost. Running costs can make a cheap loan unaffordable.
Is a longer car loan better?
A longer loan lowers monthly payment but can increase total interest and negative equity risk.
How it works
The target car budget is a percentage of monthly take-home income.
Running costs are subtracted before estimating the loan payment capacity.
The affordable loan amount is converted to a car price by adding down payment and trade-in value.
Educational planning estimate. It does not replace an official calculation or individualized financial, tax, or legal advice.
