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. This figure helps determine the size of your home loan.

• Down payment: The down payment is the amount the homebuyer pays upfront, often expressed as a percentage of the total purchase price. Most buyers put down between 3% and 20%. A down payment calculator can be helpful if you are unsure about your percentage.

• Loan term: The loan term is the duration over which you will repay your mortgage, usually 15 or 30 years, though it could be as short as 10 years. The shorter the loan term, the larger the monthly payments and the less interest you’ll pay over the life of the loan.

• Interest rate: The interest rate is how your lender computes the price you will pay to borrow money. Rates vary based on your qualifications, market trends, and type of mortgage loan. A better credit score can mean a lower interest rate.

• Property tax: Property tax is levied by local governments on land and buildings, and is expressed as a percentage of a home’s assessed value. In New Hampshire, the effective property tax rate varies depending on the location, but on average, it is 1.41%. To find your precise number, search for the property’s ZIP code or town name and “effective property tax rate.”

• Monthly payment: The monthly payment is what you would pay toward the principal and interest each month, with property tax factored in. Private mortgage insurance (PMI), homeowners insurance, and homeowners association (HOA) fees can sometimes be factored into your monthly payment.

• Total interest paid: The total interest paid is the amount of interest you will pay over the life of the loan. This figure is influenced by the principal amount, interest rate, and loan term. A higher interest rate or longer loan term will result in more interest paid.

• Total loan cost: The total loan cost is the all-in amount you will repay for the home loan, including principal and interest. This figure provides a clear picture of the financial commitment you are making and helps you compare different loan options.
