How to Use

Formula

The formula to calculate the monthly mortgage payment is as follows:

$M = P \times ( 1 + r ) ^{n} - 1 r ( 1 + r ) ^{n}$

Where:

$M$ is the monthly mortgage payment.
$P$ is the loan amount.
$r$ is the monthly interest rate (annual rate divided by 12 and multiplied by 0.01).
$n$ is the total number of payments (loan term in years multiplied by 12).

Example

Let’s say you have a $300,000 loan with an annual interest rate of 4% for 30 years. The calculation would be:

$M = 300, 000 \times ( 1 + ( 0.04/12 ) ) ^{30 \times 12} - 1 ( 0.04/12 ) ( 1 + ( 0.04/12 ) ) ^{30 \times 12}$
