SBA Loan Payment Calculator

About SBA Loan Payment Calculator

A business loan's true cost often differs meaningfully from a personal loan's in one specific way: origination fees. Many business lenders charge an upfront percentage fee deducted from the loan proceeds before the funds are disbursed — meaning you're repaying the full principal amount through your monthly payments, but actually received less than that amount in your account on day one.

This tool calculates the standard monthly payment and total interest the same way any amortizing loan does, but adds the origination fee calculation on top — showing both the fee amount and, critically, the net funds you'd actually receive after the fee is deducted. This distinction matters for accurately comparing loan offers: two loans with the same rate and term but different origination fees result in genuinely different net proceeds for the same repayment obligation.

Business loan terms are also commonly quoted in months rather than years (a 36-month term, an 18-month term), which is why this tool accepts the term directly in months rather than requiring a years-to-months conversion first — matching how most business lenders actually present their loan terms.

This is useful for comparing business loan offers with different origination fees, understanding the real net funding a loan provides versus its face value, and budgeting for the actual monthly payment obligation a business loan creates.

How it works

1. Enter the loan amount, rate, and term in months. Standard business loan terms are typically quoted in months.
2. Enter the origination fee percentage. Enter 0 if the lender doesn't charge one.
3. View your payment, total cost, and net funds received. See the monthly payment, total interest, and how the fee affects actual proceeds.
