How to use this calculator

Enter your assumptions and review the result alongside a cash-flow forecast. Compare the estimated payment with the dates your customers actually pay you. Change one input at a time to see how the term or rate affects the outcome.

Calculations run in your browser. Your financial inputs are not sent to a lender or stored by this site. A downloadable CSV gives you the full monthly repayment schedule when the modeled loan amount is positive.

Is the interest rate a current SBA rate?

No. The default is an examples. Enter the nominal annual rate quoted by your lender.

Does this calculate SBA eligibility or guarantee fees?

No. Enter actual quoted fees manually. The tool does not determine program eligibility or reproduce a 504 multi-part structure.
