How to Use

Input the loan amount in the designated field.
Enter the annual interest rate associated with your mortgage.

Press the “Calculate” button to obtain your monthly mortgage payment.

Formula

The formula used for calculating the monthly mortgage payment is as follows:

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

Where:

$M$ is the monthly 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 an example: a $200,000 loan with an annual interest rate of 4.5% over a 20-year term. Plugging these values into the formula yields the monthly payment.

$M = 200, 000 \times ( 1 + 0.00375 ) ^{240} - 1 0.00375 ( 1 + 0.00375 ) ^{240}$
