Formula Used

The mortgage payment is calculated using the standard amortization formula:

Mortgage Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

  • P = Principal loan amount
  • r = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to fully amortize a loan over the specified term.

Worked Example

Let's calculate a $25,000 auto loan with a 5.5% annual interest rate over 5 years:

  1. Principal (P) = $25,000
  2. Annual interest rate = 5.5% or 0.055
  3. Monthly interest rate (r) = 0.055 / 12 ≈ 0.004583
  4. Number of payments (n) = 5 × 12 = 60

Calculation Steps

1. Calculate (1 + r)^n = (1.004583)^60 ≈ 1.3458

2. Calculate the numerator: P × r × (1 + r)^n = 25000 × 0.004583 × 1.3458 ≈ 159.38

3. Calculate the denominator: (1 + r)^n - 1 = 1.3458 - 1 = 0.3458

4. Monthly Payment = 159.38 / 0.3458 ≈ $460.99

Your estimated monthly payment would be $461.00, with a total interest paid of $1,860.00 and a final payoff date approximately 5 years from today.
