Formula Explained

The calculator uses the standard mortgage payment formula:

Mortgage Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12)
n = Number of payments (loan term × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the specified term.

Worked Example

Let's calculate a mortgage payment for a $300,000 loan at 4.5% annual interest over 30 years:

Input	Value
Loan Amount	$300,000
Annual Interest Rate	4.5%
Loan Term	30 years
Repayment Type	Principal and Interest

Using the formula:

Calculation Steps

1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375

2. Calculate number of payments: 30 × 12 = 360

3. Plug values into formula: $300,000 × (0.00375(1 + 0.00375)^360) / ((1 + 0.00375)^360 - 1)

4. Result: $1,643.89 per month

This means you would pay approximately $1,644 per month for 30 years to fully repay the $300,000 loan.

Interpreting Results

When you run the calculator, you'll see several key results:

Monthly Payment: The fixed amount you'll pay each month.
Total Interest: The total amount paid in interest over the loan term.
Total Cost: The sum of the principal and total interest paid.

Use these results to compare different loan options and make informed decisions about your mortgage.

Important Note

These calculations are estimates based on the inputs you provide. Actual mortgage payments may vary based on additional fees, taxes, and market conditions.

Frequently Asked Questions

What is the difference between principal and interest payments?

Principal payments reduce the amount you owe on the loan, while interest payments cover the cost of borrowing. Principal and interest payments together make up your total monthly mortgage payment.

How does the interest rate affect my monthly payment?

A higher interest rate will increase your monthly payment because you'll be paying more in interest. Conversely, a lower interest rate will reduce your monthly payment.

What is the difference between fixed and variable rate mortgages?

Fixed rate mortgages have a constant interest rate throughout the loan term, while variable rate mortgages have an interest rate that can change based on market conditions. Fixed rates typically offer more stability.

How can I lower my mortgage payments?

You can lower your mortgage payments by making larger down payments, extending the loan term, or negotiating a lower interest rate. However, these options may affect your total cost of borrowing.
