Louisiana Mortgage Calculator

By SoFi Editors | Updated September 26, 2025

If you’re trying to buy a home in Louisiana, a mortgage calculator can be a useful tool for you. It can be especially helpful if you’re a first-time homebuyer who’s never held a mortgage — but also if you are a current or former homeowner looking to buy again. By exploring how various home prices, interest rates, and loan terms may affect monthly payments and the ultimate cost of a home mortgage loan, you can make smart decisions and budget responsibly.

Key Points

•   As a homebuyer, a mortgage calculator can help you determine affordability and aid in your finance management.

•   Your mortgage payments in Louisiana typically include principal, interest, and property tax. They may also comprise homeowners insurance, and other coverage and fees.

•   Lenders recommend that you choose a property that will let you keep mortgage payments under 28% of your gross monthly income.

• Home price: The home price is the purchase amount agreed upon by a buyer and seller. If you’re buying your first home in Louisiana, it will be a determiner of both your mortgage loan amount and your monthly payment.

• Down payment: A down payment is the very first installment on a home purchase, usually an amount between 3% and 20% of the home price. Down payment assistance programs can be very useful if you need help covering this cost — especially if you’re a first-time buyer. A healthy down payment can help you score better loan terms, and avoid the expense of private mortgage insurance (PMI), too.

• Loan term: This is the period of time you can take to repay your home loan. A 15-year term usually carries higher monthly payments — but in the end you’ll pay less interest. A 30-year mortgage, generally the longest term you can get, offers lower monthly payments but racks up more interest overall.

• Interest rate: The interest rate tends to be expressed as a percentage of the loan amount, and represents the cost of borrowing the money to buy a home. Your rate will be based on the type of mortgage loan you apply for, how the market trends, and your qualifications as a borrower.

• Annual property tax: Local governments levy property taxes on land and buildings using guidelines that are set by the state. In Louisiana, the effective property tax rate on owner-occupied homes is 0.51 percent. Understanding of your local rates is useful — it can help you plan your budget and avoid surprises.

• Monthly payment: This is the amount you’ll pay toward your mortgage 12 times each year. It will include principal and interest, and may comprise property taxes and homeowners insurance. If your down payment is less than 20% of your home price, PMI may also be a line item.

• Total interest paid: The amount of interest you’ll pay during your mortgage loan’s entire life is total interest paid. This cost is influenced by loan term, interest rate, and down payment. A longer term or a higher interest rate will increase the total interest you’ll pay. A larger down payment or shorter loan term can reduce this amount.

• Total loan cost: This all-in amount is what your whole loan expense will be, including principal plus interest. Thirty-year mortgages have higher total loan costs than 15-year mortgages, due to their longer repayment term and more interest accrued.
