Before you start punching in numbers, it’s helpful to understand the terms you’ll encounter in a mortgage calculator:

• Home price: The home price is the purchase price you have agreed to with the home seller, which may differ from the listing price or your initial offer. This figure is important for determining the home loan amount and the type of mortgage loan you will need.

• Down payment: The down payment is the amount the homebuyer pays up front, often expressed as a percentage of the total purchase price. Most buyers put down between 3% and 20% of a home’s value for a conventional loan. If you put down at least 20%, you won’t need private mortgage insurance (PMI). A down payment calculator can help you decide on the right number.

• Loan term: The loan term is the length of time you have to repay the mortgage. Terms are typically 15 or 30 years. A shorter term reduces the total amount of interest you’ll pay over the life of the loan but leads to higher monthly payments.

• Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the home loan amount. Interest rates vary based on your credit score, market trends, and the type of mortgage loan you choose. A higher credit score can secure a lower interest rate, reducing your monthly payments and the total cost of the loan over time.

• Annual property tax: Property tax can be a significant component of your monthly mortgage payment. This tax is based on the assessed value of your home and is administered by the local government.

• Total monthly payment: The total monthly payment includes the principal and interest on a mortgage loan, as well as the monthly property tax. This comprehensive figure gives you a clear understanding of your monthly financial commitment.

• Total interest paid: The total interest paid is the amount of interest you will pay over the life of the home loan. This figure can be substantial, especially for longer loan terms. Securing a lower mortgage rate can help reduce your monthly payments and total interest costs.

• Total loan cost: The total loan cost is the all-in amount you will repay for the home loan, including principal and interest. Factors like the length of your loan term, your interest rate, and your down payment amount all impact the total cost of your loan.
