Fixed-Rate Mortgage Calculator
Understanding Your Mortgage Payments
Purchasing a home is likely the biggest financial decision of your life. Before committing to a loan, it is crucial to understand exactly what your monthly financial obligation will look like. Our Fixed-Rate Mortgage Calculator helps you estimate your monthly "Principal & Interest" (P&I) payments based on standard loan parameters.
How This Calculator Works
This tool uses the standard amortization formula used by most lenders for fixed-rate mortgages. By inputting a few key figures, you can see how different interest rates or down payments affect your long-term costs.
- Home Price: The total purchase price of the property.
- Down Payment: The amount of cash you are paying upfront. The loan amount is the Home Price minus the Down Payment.
- Loan Term: How many years you have to repay the loan. Standard terms are typically 15 or 30 years. Shorter terms usually have lower interest rates but higher monthly payments.
- Interest Rate: The annual percentage rate you pay to borrow the money. Even a small fraction of a percentage point can significantly impact your total interest paid over time.
An Example Scenario
Imagine you are buying a home listed at $400,000. You have saved a 20% down payment, which is $80,000. This means you need to borrow a principal amount of $320,000.
If you secure a 30-year fixed-rate loan at an interest rate of 7.0%, plugging these numbers into the calculator above reveals that your monthly Principal & Interest payment would be approximately $2,129.00.
Over the full life of that 30-year loan, you would end up paying over $446,000 just in interest alone, making the total cost of the loan over $766,000.
Important Note on Escrow
Keep in mind that the figure calculated here is only for Principal and Interest. Most homeowners also pay property taxes and homeowners insurance into an escrow account each month, which are added on top of the P&I payment calculated above. You may also need to factor in Private Mortgage Insurance (PMI) if your down payment is less than 20%.
