Formula

The formula for calculating the monthly mortgage payment is:

Where:

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

Example

Let’s consider an example. For a loan amount of $200,000, an interest rate of 4%, and a loan term of 30 years:

$r = 12 \times 100 4% = 0.003333$

$n = 30 \times 12 = 360$

$M = 200, 000 \times ( 1 + 0.003333 ) ^{360} - 1 0.003333 ( 1 + 0.003333 ) ^{360}$

Result:

$M \approx 954.83$

So, the estimated monthly mortgage payment is approximately $954.83.
