Formula for Early Payoff Calculation

The monthly car loan payment for a fixed-rate loan is calculated using:

Monthly Payment (M) = [P × r × (1 + r)^n] ÷ [(1 + r)^n – 1]

Where:

  • P = Current loan balance
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Remaining number of payments

When adding extra payments:

  1. Subtract the extra payment from the principal each month.
  2. Recalculate interest on the new principal.
  3. Continue until the loan is fully paid.

This reduces both the total interest paid and the remaining loan term.


Example Calculation

Suppose you have a $15,000 remaining balance on a car loan with 5% annual interest and 36 months left, and you plan to pay an extra $100 per month.

  1. Monthly interest rate: r = 5 ÷ 12 ÷ 100 = 0.004167
  2. Standard monthly payment:

M = [15,000 × 0.004167 × (1 + 0.004167)^36] ÷ [(1 + 0.004167)^36 – 1]

Step-by-step:

  • (1 + 0.004167)^36 ≈ 1.161
  • Numerator = 15,000 × 0.004167 × 1.161 ≈ 72.64
  • Denominator = 1.161 – 1 = 0.161
  • M ≈ 72.64 ÷ 0.161 ≈ $451.25/month
  1. Add extra payment: 451.25 + 100 = $551.25/month

By paying $551.25 monthly, the loan will be paid off faster, and total interest will be reduced significantly.
