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
Imagine borrowing $18,500 for a used car at 7.25% annual interest over 54 months.
- Monthly rate r = 7.25 ÷ 100 ÷ 12 = 0.00604167, and (1 + r)54 = 1.384402.
- Monthly Payment = 18,500 × 0.00604167 × 1.384402 ÷ (1.384402 − 1) = $402.54.
- Total Cost, the payment applied across all 54 months, = $21,736.95.
- Total Interest = 21,736.95 − 18,500.00 = $3,236.95.
