Calculator Definitions

•   Home price: The home price is the purchase price you and the seller have agreed upon. This, combined with your mortgage down payment amount, will determine your loan amount.

•   Down payment: The down payment is the amount the homebuyer pays upfront. Most buyers put down between 3% and 20% of the purchase price, with a 20% down payment often helping to avoid private mortgage insurance (PMI). A jumbo loan usually has a minimum down payment of 10%.

•   Loan term: The loan term is the length of time you have to repay the home loan. A shorter term can result in higher monthly payments but less interest paid over the life of the loan, while a longer term may offer lower monthly payments but increase the total interest paid.

•   Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan term. Interest rates can vary based on your credit score, market trends, and the type of mortgage loan that you choose.

•   Annual property tax: The annual property tax is a significant component of your housing expenses. In Richland County, where Columbia is located, the property tax rate rate is .6998%. To learn the precise tax rate for a property, search the ZIP code or county name and “effective property tax rate.”

•   Total monthly payment: The total monthly payment includes the principal amount, the interest accrued, and the property tax you would pay each month.

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

•   Total loan cost: The total loan cost represents the all-in amount you will ultimately pay for the loan, including both the principal amount borrowed and the accrued interest.
