How This SBA Loan Calculator Works
Enter your loan amount, interest rate, and term, and this SBA loan payment calculator returns your estimated monthly payment and total interest using standard amortization. It works for both SBA 7(a) and SBA 504 scenarios. Use it to test different rates before you apply, or to check a payment quote a lender has given you.
SBA 7(a) vs SBA 504
The SBA 7(a) program is the most flexible option. It covers working capital, equipment, business acquisition, and owner occupied commercial real estate up to $5 million, usually with a variable rate tied to the prime rate and terms up to 10 years for most uses or 25 years for real estate. The SBA 504 program is built for real estate and major equipment. It pairs a bank loan with a fixed rate portion from a Certified Development Company, with 10, 20, or 25 year terms. The CDC portion can reach $5.5 million for qualifying projects such as manufacturing. To model a 504 loan, run the bank portion and the CDC portion separately, then add the two monthly payments together.
SBA Loan Down Payment and Rates
Most SBA borrowers put down 10 to 20 percent, depending on the program and how the funds are used. Rates on 7(a) loans move with the prime rate, while the 504 CDC portion carries a fixed rate. Because rates change, run a few different numbers through the calculator to see how your monthly payment shifts.
