Estimate vehicle financing from price, entered credits, financed fees, rate, and term.
The calculator keeps the balance, rate convention, payment timing, fees, and term visible so you can reproduce the result and compare it with an actual offer or statement.
The cash-flow relationship
Place every amount at the correct time
Amount financed = vehicle price − down payment − trade-in credit + financed fees; that balance uses level monthly amortization.

Read the result in context
Use the estimate with its contract assumptions
A 30,000 vehicle with 5,000 down, 2,000 trade-in credit, and 500 financed fees leaves 23,500 to finance.
Enter only confirmed amounts. The calculator does not guess taxes, registration costs, trade-in debt, insurance, dealer charges, or location-specific fees.
Quick guide
How to use this calculator
Enter every amount in one consistent currency.
Use the nominal annual rate and whole-number monthly timing requested by each label.
Read the result together with the stated timing convention and calculator-specific exclusions.
Calculation method
Calculation method
Amount financed = vehicle price − down payment − trade-in credit + financed fees; that balance uses level monthly amortization.
Entered monetary components are aggregated as exact fixed decimals. Amortization keeps full calculation precision and rounds only for presentation; a nonzero supported result is never displayed as zero.
Worked example
Worked example
A 30,000 vehicle with 5,000 down, 2,000 trade-in credit, and 500 financed fees leaves 23,500 to finance.
Amount financed = vehicle price − down payment − trade-in credit + financed fees; that balance uses level monthly amortization.
Supported inputs
Precision and limits
Visible input limits
Amounts are capped at 1e12, nominal annual rates at 1000%, schedules at 1,200 months, and fixed-decimal inputs at 12 decimal places.
Estimate, not an offer
Results model only the entered values. A lender or contract may use different payment dates, day counts, compounding, fee treatment, statement rounding, or allocation rules.
International scope
No currency, country, tax, credit-scoring system, consumer-credit law, or lender policy is assumed. Location-dependent amounts must be entered explicitly.
Calculator-specific assumptions
Enter only confirmed amounts. The calculator does not guess taxes, registration costs, trade-in debt, insurance, dealer charges, or location-specific fees.
