How this is calculated

This calculator estimates a standard fully-amortizing loan payment and, if you provide your expected monthly net operating income, checks it against the debt service coverage ratio most SBA lenders require. It's a planning estimate, not a lending decision — actual terms depend on your specific lender's underwriting.

  • Principal = loan amount minus your down payment.
  • Monthly payment = standard amortization: principal × monthly rate ÷ (1 − (1 + monthly rate)^−months), where monthly rate is your annual rate divided by 12.
  • Total interest = total of all payments over the term minus the principal.
  • Debt service coverage ratio (DSCR) = monthly net operating income ÷ monthly payment. Most SBA 7(a) lenders look for at least 1.25x — below that, a deal is harder to underwrite even if the math otherwise pencils.
  • This models a standard fully-amortizing loan. It doesn't account for SBA guaranty fees, closing costs, or a variable-rate loan's rate resets — build those into your total investment separately.

Worked example

A $350,000 loan at 15% down (financing $297,500) at 11% over 10 years runs about $4,098/month — check your own numbers above.
