Formula

The formula for calculating the monthly mortgage payment for a fixed-rate loan is:

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

Where:

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

Example

Let’s consider a loan amount of $200,000, an annual interest rate of 4%, and a 30-year loan term. Plugging these values into the formula:

$M = 200, 000 \cdot ( 1 + 0.04/12 ) ^{30 \cdot 12} - 1 0.04/12 ( 1 + 0.04/12 ) ^{30 \cdot 12}$

After calculation, the monthly mortgage payment is approximately $954.83.
