Mortgage Payment Calculator
What Is a Mortgage Payment Calculator?
A mortgage payment calculator helps home buyers determine their estimated monthly mortgage payments based on principal loan amount, interest rate, and loan term. Understanding your monthly obligation is essential before buying a home or refinancing your existing loan.
Mortgage Formula Explained
M = P × [ r(1+r)^n ] ÷ [ (1+r)^n − 1 ]
- M: Monthly payment
- P: Principal loan amount
- r: Monthly interest rate (Annual rate ÷ 12)
- n: Total number of monthly payments (Years × 12)
Example: A $250,000 mortgage at 6.5% annual interest over 30 years results in a monthly payment of $1,580.17. Total repayment over 30 years equals $568,861, including $318,861 in total interest.
Key Factors Affecting Your Mortgage Payment
1. Down Payment: A larger down payment reduces the total principal borrowed, lowering both monthly payments and total interest paid.
2. Interest Rate: Even a 0.5% rate reduction can save tens of thousands of dollars over the life of a loan.
3. Loan Term: A 15-year mortgage has higher monthly payments than a 30-year loan, but significantly lowers overall interest paid.
