Calculator Definitions

•   Home price: The home price is the purchase price you and the home seller have agreed upon. It might be different from the listing price or your initial offer.

•   Down payment: The down payment is the amount a homebuyer pays upfront, typically between 3% and 20%. If you make a 20% down payment, you usually won’t need to also pay for private mortgage insurance (PMI). A jumbo loan for a pricier property may require at least 10% down.

•   Loan term: The loan term is the length of time you have to repay the loan, typically 15 or 30 years. A 30-year term offers lower monthly payments, while a 15-year term can save you a significant amount in interest over the life of the loan.

•   Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the home loan amount. A lower interest rate can significantly reduce your monthly payments and the total interest paid over the life of the loan.

•   Annual property tax: The annual property tax can be part of your monthly mortgage payment. In California, property tax is capped at 1%; in Stanislaus County, where Modesto is located, the rate is .7091%. Find your specific rate by searching for the ZIP code or county and “effective property tax rate.”

•   Total monthly payment: The total monthly payment includes the principal, interest, and property tax.

•   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. A lower interest rate can reduce your monthly payments and the overall cost of the mortgage.

•   Total loan cost: The total loan cost is the all-in amount you will pay for the home loan, including both principal and interest.
