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 you would pay upfront, often expressed as a percentage of the total purchase price. Most buyers put down between 3% and 20%. A larger down payment can reduce your monthly mortgage payment and the total interest paid.

• Loan term: The loan term is the length of time you have to repay the mortgage, between 10 and 30 years. The longer the term, the lower your monthly payments — but the more interest you’ll pay over the life of the loan.

• Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. It 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 the home’s assessed value. Search for the ZIP code or county name where the property is located and “effective property tax rate” to find the number, or use the New Jersey average of 1.77%.

• Monthly payment: This is what you would pay toward the principal, interest, and property taxes each month. Your monthly payment may also include private mortgage insurance (PMI) if your down payment is less than 20%, homeowners insurance, and homeowners association (HOA) fees, if applicable.

• Total interest paid: The total interest paid is the amount of interest you will pay over the life of the loan. It 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.
