•  Home price: The home price is the purchase price you have agreed to with the home seller. A higher home price will generally result in a larger loan amount and higher monthly payments, so it’s important to consider your budget and the local market conditions when determining the right price for your new home.

•  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 larger down payment can reduce your monthly mortgage payments and potentially eliminate the need for private mortgage insurance (PMI).

•  Loan term: The loan term is the length of time you have to repay the mortgage. A 15-year mortgage term can help you build equity faster and pay less interest over the life of the loan, but it comes with higher monthly payments. Conversely, a 30-year term offers lower monthly payments, making it more manageable for many homebuyers.

•  Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. Interest rates can vary based on your credit score, market trends, and the type of mortgage loan you choose. A lower interest rate can significantly reduce your monthly payments and the total interest you pay over the life of the loan.

•  Annual property tax: Property tax is administered by the local government and is usually expressed as a percentage of the home’s assessed value. In Idaho Falls, property taxes are 0.55%.

•  Total monthly payment: The total monthly payment includes the principal and interest you will pay each month. This calculator also includes property tax. Additionally, your payment may incorporate homeowners insurance, homeowners association (HOA) fees, and private mortgage insurance (PMI).

•  Total interest paid: This is the amount of interest you will pay over the life of the loan. This figure is influenced by the interest rate, the loan term, and the loan amount. A lower interest rate or a shorter loan term can significantly reduce this amount.

•  Total loan cost: The total loan cost represents the all-in amount you will ultimately repay for the loan, encompassing both the principal amount and the accumulated interest.
