What this calculator does
Estimate an affordable vehicle price from a monthly payment budget, financing terms, down payment, trade-in, taxes, and fees.
How it works
The calculator evaluates loan principal = payment × annuity PV factor; vehicle price solves financed amount = price + tax + fees − down payment − trade-in. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
