Car Affordability Calculator
Estimate a vehicle budget from income.
What this car affordability calculator does
Estimate a vehicle budget using income, expenses, down payment and financing assumptions.
How to use the calculator
Start with a monthly budget you can comfortably maintain rather than the largest payment a lender might approve. Include insurance, fuel, maintenance and registration in your broader transportation budget.
How the calculation works
The calculator uses your stated income and budget assumptions to estimate a vehicle price or payment range. It is a planning model, not a lending decision.
What the result means
The number shown is best used as a planning estimate. Change one assumption at a time to see which inputs have the largest effect. For financial decisions, compare the result with current statements, lender disclosures, employer information or other authoritative records.
Important assumptions and limitations
CFPB recommends considering the full cost of vehicle ownership—not only the loan payment—including insurance, maintenance and fuel. Compare lenders before financing.
