How Does a Mortgage Work?

A mortgage is a loan specifically used to purchase real estate. When you take out a mortgage, you agree to pay back the principal (the amount you borrowed) plus interest over a set period, typically 15 or 30 years.

Understanding how your monthly payment is calculated is crucial for budgeting and determining how much house you can afford. Our mortgage calculator breaks down your payments so you can see exactly how much you're spending on the principal versus interest.

Key Components of Your Payment

While our calculator provides a streamlined view of your core loan costs, it's important to know the four main components of a standard mortgage payment, often referred to as PITI:

• Principal: The portion of your payment that pays down the actual loan balance.
• Interest: The cost you pay to the lender for borrowing the money. Interest is heavily front-loaded in the early years of a standard amortized loan.
• Taxes: Property taxes assessed by your local government, usually collected monthly and held in escrow.
• Insurance: Homeowners insurance to protect the property, and potentially Private Mortgage Insurance (PMI) if your down payment is less than 20%.

The Impact of Interest Rates and Loan Terms

Small changes in your interest rate can dramatically affect both your monthly payment and the total cost of the loan over time. A lower interest rate can save you tens of thousands of dollars over a 30-year term.

Additionally, choosing a 15-year mortgage instead of a 30-year mortgage will result in higher monthly payments, but you will pay significantly less total interest and build equity in your home much faster. Use our calculator to experiment with different rates and terms to see which scenario fits your financial goals.
