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
Take a $22,000 car loan at 5.9% annual interest over 48 months.
- Monthly rate r = 5.9 ÷ 100 ÷ 12 = 0.00491667, and (1 + r)48 = 1.265442.
- Monthly Payment = 22,000 × 0.00491667 × 1.265442 ÷ (1.265442 − 1) = $515.66.
- Total Cost, the payment applied across all 48 months, = $24,751.80.
- Total Interest = 24,751.80 − 22,000.00 = $2,751.80.
