How to Use

The calculator is designed for ease of use. Enter the loan amount, interest rate, and loan term. Click the “Calculate” button, and the tool will provide you with the monthly payment for your home loan.

Formula

The formula for calculating monthly mortgage payments is based on the loan amount ( $P$ ), interest rate ( $r$ ), and loan term in months ( $n$ ). The accurate formula is:

$M = ( 1 + 12 r ) ^{12 \cdot n} - 1 P \cdot 12 r \cdot ( 1 + 12 r ) ^{12 \cdot n}$

Where:

$M$ is the monthly payment.
$r$ is the monthly interest rate (annual rate divided by 12).
$n$ 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 loan term of 30 years. Using the formula:

$M = ( 1 + 120.04 ) ^{12 \cdot 30} - 1200000 \cdot 120.04 \cdot ( 1 + 120.04 ) ^{12 \cdot 30}$

The calculated monthly payment is approximately $955.73.
