What Moves the Needle Most
How much each factor changes your Max Affordable Car across its full range. Interest Rate has the biggest impact.
Focus your attention on Interest Rate — getting it right matters most. Factors lower down move the result less, so rough estimates there are fine.
Confidence & Assumptions
The outcome is fairly stable across best and worst cases — this is a robust decision.
Max Car Price: €29,998 (worst) → €6,172,303 (expected) → €5,000 (best)
These are the estimates the result depends on. Adjust them (and the Advanced inputs) to match your real situation — the closer they are to reality, the more reliable your decision.

How This Calculator Works
What this calculator does
This calculator determines the maximum car price you can afford based on your monthly income, expenses, down payment, and loan terms. It uses the rule that your car payment should not exceed a set percentage of your income.
How the calculation works
We calculate the maximum monthly payment you can afford (as a % of income), then derive the maximum loan amount from that payment using the loan EMI formula. Adding your down payment gives the maximum car price.
Formula
Max Payment = Monthly Income × Max % Max Loan = Payment × [(1+r)^n - 1] / [r × (1+r)^n] Max Car Price = Max Loan + Down Payment r = monthly rate, n = total months
Example
€4,000/month income, 15% max payment = €600/month. At 7% for 5 years, max loan = €30,330. With €5,000 down, max car price = €35,330.

Factors to Consider
- Financial experts recommend spending max 15-20% of income on total car costs
- A larger down payment reduces your loan and monthly payment
- Shorter loan terms mean higher payments but less total interest
- Remember insurance, fuel, and maintenance on top of the payment
- Your emergency fund should not be used as down payment
Common Mistakes
- Buying a car that costs more than half your annual income
- Taking long loans (7+ years) just to afford the monthly payment
- Forgetting insurance, fuel, and maintenance in the budget
- Using the full approved loan amount instead of what you can afford
- Not considering depreciation on new vs used cars
Frequently Asked Questions
How much should I spend on a car?+
A common rule is the 20/4/10 rule: 20% down, 4-year loan, total car costs under 10% of income. More conservatively, keep the car price under 50% of your annual income.
Should I put 20% down?+
A 20% down payment prevents being underwater on the loan (owing more than the car is worth) and reduces monthly payments and total interest.
What is the 20/4/10 rule?+
Put at least 20% down, finance for no more than 4 years, and keep total monthly car costs (payment + insurance + fuel) under 10% of your gross income.
