When to use this calculator
Use this SBA loan calculator to estimate payments for a longer-term business loan with a guarantee or closing fee. It is useful for planning larger business financing where fees and term length matter.
Formula
Financed amount = loan amount + loan amount x fee percentage
- Loan amount is the principal borrowed before fees.
- Fee percentage estimates guarantee or closing fees.
- Rate and term estimate monthly payment and total interest.
Worked example
For a $250,000 loan at 9.5% over 10 years with a 2% fee, the calculator estimates the financed amount and monthly payment.
Common mistakes
- Ignoring guarantee or closing fees.
- Assuming the lowest advertised rate applies to every borrower.
- Using payment estimates without checking business cash flow.
