Calculator Definitions

•  Jumbo loan: A jumbo loan is a mortgage that exceeds the Federal Housing Finance Agency’s (FHFA) conforming loan limits.

•  Home price: The home price is the purchase price you’ve agreed upon with the home seller. It affects your estimated monthly mortgage payment, total interest paid, and overall loan cost.

•  Down payment: The down payment is the initial amount paid upfront. Jumbo loan requirements can be more strict, and you’ll typically need to put down at least 10% of the home price for this type of mortgage loan.

•  Loan term: The loan term (typically 30 or 15 years) is the duration to repay the mortgage. Terms of 10 or 20 years are also available. A longer term will reduce your monthly payments but increase your total interest paid; a shorter term saves on interest but increases monthly payments.

•  Interest rate: The interest rate is the charge for borrowing money, calculated as a percentage of the total loan amount.

•  Annual property tax: Property tax is a fee charged by local governments on land and structures, usually calculated as a percentage of the property’s assessed value, which may not be the same as its market value.
