Use this mortgage calculator to determine your monthly payments, total interest paid, and amortization schedule. Whether you're a first-time homebuyer or refinancing, this tool provides clear insights into your mortgage obligations.
How the Mortgage Calculator Works
The mortgage calculator uses standard financial formulas to compute your monthly payments based on the loan amount, interest rate, and loan term. It also provides an amortization schedule showing how your loan balance decreases over time.
Key Terms
- Principal: The amount borrowed for the mortgage
- Interest Rate: The annual percentage rate charged by the lender
- Loan Term: The length of the mortgage in years
- Monthly Payment: The amount paid each month including principal and interest
- Total Interest: The total amount paid in interest over the life of the loan
How to Use the Calculator
- Enter the loan amount you're seeking
- Input the annual interest rate offered by your lender
- Select the loan term in years
- Click "Calculate" to see your monthly payment and other details
This calculator assumes a fixed interest rate and monthly payments. It does not account for property taxes, insurance, or other closing costs. For a more comprehensive estimate, consult with a mortgage professional.
Mortgage Formula
The monthly mortgage payment is calculated using the following formula:
Mortgage Payment Formula
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 uses the standard annuity payment calculation where payments are made at the end of each period. The calculator applies this formula to determine your monthly payment and then calculates the total interest paid over the life of the loan.
Worked Example
Let's calculate a mortgage payment for a $200,000 loan at 4.5% annual interest for 30 years.
Example Calculation
Principal (P) = $200,000
Annual Interest Rate = 4.5% or 0.045
Monthly Interest Rate (i) = 0.045 / 12 = 0.00375
Number of Payments (n) = 30 years × 12 = 360
Monthly Payment (M) = $200,000 [ 0.00375(1 + 0.00375)360 ] / [ (1 + 0.00375)360 - 1 ]
Calculated Monthly Payment ≈ $1,073.64
For this example, the monthly payment would be approximately $1,073.64. Over 30 years, you would pay a total of $282,472 in interest, with the total amount repaid being $482,472.
| Description | Amount |
|---|---|
| Monthly Payment | $1,073.64 |
| Total Interest Paid | $282,472 |
| Total Amount Repaid | $482,472 |
