Car Affordability Calculator
Calculate the maximum car price you can afford based on your monthly budget, loan terms, and down payment.
Setting your monthly budget realistically
A common guideline suggests keeping total vehicle costs (payment, insurance, fuel, and maintenance combined) under about 15-20% of take-home pay — meaning your loan payment alone should typically be less than that full percentage, since insurance and fuel add meaningfully on top.
It's worth budgeting for these additional costs before deciding your maximum monthly payment — a car that's affordable on payment alone can still strain a budget once insurance, fuel, and maintenance are factored in, especially for newer or higher-performance vehicles.
How loan term affects what you can afford
A longer loan term lowers the monthly payment for the same total loan amount, which can make a more expensive car appear 'affordable' — but it also means paying more in total interest and staying in debt longer, sometimes longer than the car's useful life or warranty coverage.
It's worth running this calculator with a couple of different term lengths to see the trade-off directly — a shorter term with a smaller max car price is often the more financially conservative choice, even if it means buying a less expensive vehicle.
Frequently asked questions
Should my monthly payment be my only car budget consideration?
No — insurance, fuel, and maintenance add meaningfully on top of the loan payment. A common guideline suggests keeping total vehicle costs under roughly 15-20% of take-home pay, not just the loan payment alone.
Does a longer loan term let me afford a more expensive car?
It lowers the monthly payment for the same loan amount, which can make a pricier car fit your budget on paper, but it also increases total interest paid and extends how long you're in debt — worth weighing against the immediate affordability benefit.
