Mortgage Formula

The monthly mortgage payment is calculated using the following formula:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

Where:

M = Monthly payment
P = Principal loan amount (Home price - Down payment)
i = Monthly interest rate (Annual rate / 12 / 100)
n = Number of payments (Amortization period in years × 12)

This formula accounts for the interest you'll pay over the life of the loan and how it affects your monthly payments.

Worked Example

Let's calculate a mortgage for a $400,000 home with a 20% down payment, a 25-year amortization period, and a 5% annual interest rate.

Principal (P) = $400,000 - ($400,000 × 0.20) = $320,000
Monthly interest rate (i) = 5% / 12 / 100 = 0.004167
Number of payments (n) = 25 × 12 = 300
Plugging into the formula: M = $320,000 [ 0.004167(1 + 0.004167)³⁰⁰ ] / [ (1 + 0.004167)³⁰⁰ - 1 ]
Calculating gives approximately $2,178.42 per month

This example shows that with these terms, your monthly payment would be about $2,178.42. The total interest paid over 25 years would be approximately $242,520.

Frequently Asked Questions

What is the difference between fixed and variable mortgage rates?

A fixed-rate mortgage has an interest rate that stays the same for the entire loan term, while a variable-rate mortgage (also called adjustable-rate mortgage) has an interest rate that can change over time based on market conditions. Fixed rates typically offer more stability, while variable rates may offer lower initial rates.

How does the amortization period affect my mortgage?

The amortization period is the length of time you have to pay back your mortgage. A longer amortization period (e.g., 30 years) means lower monthly payments but more total interest paid over time. A shorter period (e.g., 15 years) means higher monthly payments but less total interest.

What is a mortgage pre-payment penalty?

A pre-payment penalty is a fee charged by your lender if you pay off your mortgage before the agreed-upon term. These penalties are common with variable-rate mortgages and can discourage early repayment. Always check your mortgage agreement to understand any pre-payment penalties.

Can I get a mortgage with a low credit score?

It's possible to get a mortgage with a low credit score, but you may face higher interest rates or require a larger down payment. Some lenders specialize in helping people with lower credit scores. It's important to shop around and compare offers to find the best terms for your situation.
