How It Works

Our SBA 7(a) Loan Calculator helps you estimate your monthly loan payments, including the mandatory guarantee fee. Understand the true cost of an SBA loan and compare it against conventional loan options to make informed financial decisions for your business in 2026.

The calculator determines monthly payments using a standard amortization formula, incorporating the SBA guarantee fee (ranging from 0% to 3.75% of the guaranteed portion, depending on loan size, for 2026). It also allows for a direct comparison of total interest paid and monthly payments between SBA and conventional loans.

Remember that the SBA guarantee fee is an upfront cost, often financed into the loan, increasing your total loan amount. Don't forget to account for potential additional closing costs that aren't included in this calculator.

Example: $250,000 SBA 7(a) Loan

  1. 1 Input a $250,000 loan amount, a 10-year term, and an interest rate of 8.5%. For an SBA 7(a) loan of this size, the guarantee fee is 3.0% of the guaranteed portion.
  2. 2 The calculator will add the guarantee fee to the principal (assuming 75% guaranteed, so $250,000 + (0.75 * $250,000 * 0.03) = $255,625 total financed). It then calculates the monthly payment based on this new principal.
  3. 3 The result will show an estimated monthly SBA loan payment of approximately $3,140. It will also display the total interest paid over the loan term and allow you to compare this to a conventional loan at a different rate.
  4. 4 This payment includes the financing of the SBA guarantee fee. Comparing this to a conventional loan at, say, 9.0% without a guarantee fee, you can see if the SBA loan's lower interest rate truly offers a better overall deal.
