How This Calculator Works
This calculator applies the SBA 7(a) guarantee fee schedule to determine the upfront fee: 2% for loans up to $150,000, 3% for $150,001-$700,000, and 3.5% for loans over $700,000, each applied to the guaranteed portion (loan amount multiplied by the guarantee percentage). The fee is added to the principal to model the common practice of financing the guarantee fee. Monthly payments are computed using the standard amortization formula: M = P[r(1+r)^n] / [(1+r)^n - 1]. The calculator assumes a fixed rate, though most 7(a) loans carry variable rates tied to the Wall Street Journal prime rate that adjust quarterly. It does not model the SBA annual servicing fee (approximately 0.55% of the outstanding guaranteed balance) or lender-specific closing costs. Actual payments on a variable-rate loan will fluctuate with changes in the prime rate.
