Formula Used

The mortgage payment calculation uses the standard amortized loan formula:

Mortgage Payment Formula

M = P [i(1 + i)ⁿ] / [(1 + i)ⁿ - 1]

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (amortization period × payment frequency per year)

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

Worked Example

Let's calculate a mortgage payment for a $300,000 loan with a 5-year term at 5% annual interest, paid monthly.

Example Calculation

Principal (P): $300,000

Amortization Period: 5 years

Annual Interest Rate: 5%

Payment Frequency: Monthly

Monthly Interest Rate (i): 5% ÷ 12 = 0.4167%

Number of Payments (n): 5 × 12 = 60

Calculation:

M = $300,000 [0.004167(1 + 0.004167)⁶⁰] / [(1 + 0.004167)⁶⁰ - 1]

M ≈ $300,000 [0.004167 × 1.2816] / [1.2816 - 1]

M ≈ $300,000 [0.005305] / 0.2816

M ≈ $300,000 × 0.01884 / 0.2816

M ≈ $5,652.50 / 0.2816

Result: $20,075.00 per month

This example shows that with a 5% interest rate, your monthly payment would be approximately $20,075 for a $300,000 loan over 5 years.
