Key Points

Calculator Definitions

• Home price: The home price is the purchase price you have agreed to with the home seller. It may differ from the listing price and your initial offer. This figure plus the down payment amount will determine the size of your home loan.

• Down payment: The down payment represents the amount the homebuyer initially pays upfront when purchasing a property. Most buyers put down between 3% and 20% of the home’s value.

• Loan term: The loan term is the duration over which you will repay your mortgage, anywhere from 10 to 30 years. A 15-year fixed loan means higher monthly payments but less interest paid over the life of the loan. A 30-year fixed loan offers lower monthly payments and more financial flexibility. The best choice depends on your financial situation and long-term goals.

• Interest rate: The interest rate is the cost of borrowing money, expressed as a percentage of the loan amount. Interest rates vary based on borrower qualifications, market trends, and the type of mortgage loan. A higher credit score can lead to a lower interest rate, reducing monthly payments and the total cost of the loan. Shop around for the best rates to ensure favorable terms.

• Annual property tax: Property tax is levied by local governments on both land and buildings; it’s typically expressed as a percentage of the home’s assessed value.

• Monthly payment: The South Dakota calculator helps you determine what you would pay toward the principal and interest each month. This calculator’s payment includes the principal, interest, and property taxes.

• Total interest paid: The total interest paid is the amount of interest you will pay over the entire life of the loan. This figure can be substantial, especially for longer loan terms.

• Total loan cost: The total loan cost is the all-in amount you will repay for the loan, including principal and interest. A longer loan term may result in lower monthly payments but a higher total loan cost due to more interest paid over time.
