Formula Used in Mortgage Loan Calculations

The Mortgage Loan Calculator uses the standard mortgage repayment formula:

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

Where:

• M = Monthly mortgage payment
• P = Principal loan amount
• r = Monthly interest rate
• n = Total monthly payments

This formula calculates fixed monthly mortgage installments over the selected loan term.

Example of a Mortgage Loan Calculation

Suppose a borrower applies for a mortgage loan with the following details:

• Loan amount: $500,000
• Interest rate: 5%
• Loan term: 30 years

Estimated Results

• Monthly payment: Approximately $2,684
