This mortgage calculator helps you estimate your monthly payments, total interest, and amortization schedule. Whether you're a first-time homebuyer or looking to refinance, this tool provides clear insights into your mortgage costs.

How to Use This Calculator

Using the mortgage calculator is simple:

Enter your loan amount in the "Loan Amount" field.
Input your interest rate (APR) in the "Interest Rate" field.
Select the loan term in years from the dropdown menu.
Click "Calculate" to see your monthly payment and other details.
Use the "Reset" button to clear all fields and start over.

The calculator will display your estimated monthly payment, total interest paid over the life of the loan, and a breakdown of how much principal and interest you'll pay each month.

Formula Explained

The mortgage payment calculation uses the standard formula for amortized loans:

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

Where:

M = Monthly payment
P = Principal loan amount
i = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years multiplied by 12)

This formula accounts for the interest you'll pay each month and how it compounds over the life of the loan. The calculator uses this formula to provide an accurate estimate of your monthly payments.

Worked Example

Let's say you're taking out a $200,000 mortgage at 4% interest for 30 years. Here's how the calculation works:

Convert the annual interest rate to a monthly rate: 4% ÷ 12 = 0.3333%
Calculate the number of payments: 30 years × 12 = 360 payments
Plug the values into the formula:

M = $200,000 [ 0.003333(1 + 0.003333)³⁶⁰ ] / [ (1 + 0.003333)³⁶⁰ - 1 ]
The calculation results in a monthly payment of approximately $1,073.64.

This example shows how the mortgage calculator can help you understand your financial commitment when purchasing a home.

Frequently Asked Questions

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total cost of credit over one year, including any fees. The interest rate is the portion of APR that represents the cost of borrowing. APR is typically higher than the interest rate because it includes fees.

How does a mortgage term affect my payments?

A longer mortgage term means lower monthly payments but more total interest paid over the life of the loan. A shorter term results in higher monthly payments but less total interest. Choose a term that fits your budget and financial goals.

What is PMI and when do I need it?

PMI (Private Mortgage Insurance) is required when you put down less than 20% of the home's value. It protects the lender if you default. PMI is typically removed once your equity reaches 20%.
