Estimate Monthly Payment
Understanding Your Mortgage
A mortgage is likely the largest debt you will ever take on. Understanding how your monthly payments are calculated is crucial for financial planning.
Key Factors Affecting Your Payment
- Principal: The total amount of money you borrow to purchase your home.
- Interest Rate: The cost of borrowing money, expressed as a percentage. Even a small difference (e.g., 0.5%) can save you thousands over the life of the loan.
- Loan Term: The length of time you have to repay the loan. 30-year and 15-year terms are the most common in the US.
How to use this tool
Enter the total loan amount (house price minus down payment), the current annual interest rate, and the number of years for the loan. The calculator will output the portion of your monthly payment that goes toward principal and interest.
