How Much Car Can I Afford?

A lender approving you for a certain loan amount isn't the same as that amount being genuinely affordable for your budget — lenders often approve more than is comfortable once you factor in your full financial picture.

A common budgeting guideline

A widely used rule of thumb is keeping total vehicle costs — payment, insurance, fuel, and maintenance combined — under about 15-20% of your monthly take-home pay. This is a starting guideline, not a hard rule, but it's a useful gut-check against a lender's approval amount.

Costs beyond the monthly payment

• Insurance, which varies significantly by vehicle type, your driving record, and location
• Fuel costs based on your typical driving distance and the vehicle's efficiency
• Routine maintenance and the likelihood of repairs based on the vehicle's age and mileage
• Registration and any ongoing state fees

How to set your real number

Add up your essential monthly expenses and savings goals first, then see what's realistically left over for total vehicle costs — not just a payment that happens to fit what's left after everything else, calculated backward. This keeps the car within your actual financial picture rather than stretching it.
