Car Financing Calculator

Estimate monthly payment, total interest and total payable using a flat monthly interest (interest is not calculated on a reducing balance).

Enter monthly rate as a percentage (not annual).

This calculator uses a flat monthly interest model: Total Interest = Principal × (monthly rate) × (months). Monthly payment = (Principal + Total Interest) ÷ Months.

Designed for quick estimates. For amortized (reducing-balance) schedules, use a different calculator.
