Calculator Definitions

• 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.

• Down payment: The down payment is the amount the homebuyer pays upfront. Most buyers put down between 3% and 20%, with a 20% down payment eliminating the need for private mortgage insurance (PMI). A down payment calculator computes the percentage you’d be putting down based on your dollar amount.

• Loan term: The loan term is the length of time you have to repay the mortgage, which can be from 10 to 30 years. A longer term offers lower monthly payments but results in more interest paid over the life of the loan. Conversely, a shorter term has higher monthly payments but can save you a lot of interest.

• Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the home loan amount. Interest rates can vary based on borrower qualifications, market trends, and the type of mortgage loan.

• Annual property tax: Property tax is levied by local governments on land and buildings, and is expressed as a percentage of a property’s assessed value. The average rate in Massachusetts is 0.97%; for a specific rate, search for the property’s town name or ZIP code and “effective property tax rate.”

• Monthly payment: The monthly mortgage payment includes the principal and interest, and this calculator also includes property taxes. Some borrowers will also have homeowners insurance and PMI rolled into their payments.

• Total interest paid: The total interest paid is the amount of interest you will pay over the life of the loan. This figure can be significantly affected by the interest rate and loan term.

• Total loan cost: The total loan cost is the all-in amount you will repay for the loan, including the principal and interest. This cost is influenced by the loan amount, interest rate, and loan term.
