Mortgage Calculator
A mortgage calculator is an essential tool for anyone considering taking out a mortgage or refinancing their existing home loan. It helps you estimate your monthly payments based on the loan amount, interest rate, and term length. Understanding these payments can help you make informed financial decisions and plan your budget effectively. The formula used in this calculator is designed to simplify the calculation of your monthly mortgage payment, enabling you to see how different variables affect your overall payment.
Formula
The formula for calculating the monthly mortgage payment is:
P = L[c(1 + c)ⁿ] / [(1 + c)ⁿ – 1]
Where:
- P is the monthly payment,
- L is the loan amount,
- c is the monthly interest rate (annual interest rate divided by 12),
- n is the number of payments (loan term in years multiplied by 12).
How to Use
- Input the loan amount you wish to borrow.
- Enter the annual interest rate (as a percentage).
- Specify the loan term in years.
- Click the “Calculate” button to obtain your estimated monthly payment.
Example
For example, if you are looking to borrow $300,000 at an annual interest rate of 4% for a term of 30 years, the calculation would proceed as follows:
- Loan Amount (L): $300,000
- Annual Interest Rate: 4% → Monthly Rate (c): 0.33% (4/12)
- Loan Term (n): 30 years → 360 payments (30*12)
Using the formula, the monthly payment (P) can be calculated. For this example, the result will show approximately $1,432.25 as the monthly payment.
