Formula Used

The mortgage payment calculator uses the standard mortgage payment 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 (loan term in years multiplied by 12)

This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.

Worked Example

Let's calculate the monthly payment for a $100,000 loan with a 5% annual interest rate over 30 years.

Convert the annual interest rate to a monthly rate: 5% ÷ 12 = 0.4167% or 0.004167 in decimal form.
Calculate the number of payments: 30 years × 12 = 360 payments.
Plug the values into the formula:

M = $100,000 [ 0.004167(1 + 0.004167)^360 ] / [ (1 + 0.004167)^360 - 1 ]
Calculate the numerator: 0.004167 × (1.004167)^360 ≈ 1.703
Calculate the denominator: (1.004167)^360 - 1 ≈ 1.703 - 1 = 0.703
Divide the numerator by the denominator: 1.703 / 0.703 ≈ 2.423
Multiply by the principal: $100,000 × 2.423 ≈ $242,300
Divide by the number of payments: $242,300 / 360 ≈ $673.06

The estimated monthly payment for this loan is $673.06.
