This mortgage calculator helps you estimate your monthly mortgage payments based on loan amount, interest rate, and loan term. It uses standard amortization calculations to provide an accurate estimate of your mortgage payments.
How to Use This Calculator
To use this mortgage calculator, follow these simple steps:
- Enter the loan amount you're planning to borrow.
- Input the annual interest rate for your mortgage.
- Select the loan term in years.
- Click the "Calculate" button to see your estimated monthly payment.
The calculator will display your estimated monthly payment, total interest paid over the life of the loan, and a breakdown of your payments over time.
Mortgage Payment 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 accounts for the interest on the loan balance and ensures that the loan is fully repaid over the selected term.
Example Calculation
Let's look at an example to understand how the mortgage calculator works.
Example Scenario
- Loan amount: $200,000
- Annual interest rate: 4.5%
- Loan term: 30 years
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:
M = $200,000 [ 0.00375(1 + 0.00375)^360 ] / [ (1 + 0.00375)^360 - 1 ]
4. Calculate the monthly payment: $200,000 × 0.005249 ≈ $1,049.85
In this example, the estimated monthly payment would be $1,049.85.
