Your Summary
Explanation
About Vehicle Finance Calculator
Whatever you are financing on wheels, the payment depends on three things: how much you borrow, the annual rate, and how many months you take to repay. Enter those here and the vehicle finance calculator returns the monthly payment.
It also totals the interest and the overall cost for the full term.
Formula & Mathematical Calculation
pmt = r === 0 ? (p ÷ n) : (p × r × pow(1 + r, n)) ÷ (pow(1 + r, n) - 1)
tot = pmt × n
Derived directly from the verified calculation function in the tool engine.
Calculation Example
Financing $31,000 at 6.0% annual interest over 66 months works out as follows.
- Monthly rate r = 6.0 ÷ 100 ÷ 12 = 0.005, and (1 + r)66 = 1.389825.
- Monthly Payment = 31,000 × 0.005 × 1.389825 ÷ (1.389825 − 1) = $552.61.
- Total Cost, the payment applied across all 66 months, = $36,472.55.
- Total Interest = 36,472.55 − 31,000.00 = $5,472.55.
