How This Calculator Works
This calculator computes the SBA guarantee fee using the tiered schedule: 2% of the guaranteed portion for loans up to $150,000, 3% for $150,001-$700,000, and 3.5% for loans above $700,000. The guaranteed portion equals the loan amount multiplied by the guarantee percentage you select (75% or 85%). The guarantee fee is added to the loan principal, reflecting the common practice of financing the fee. Monthly payments are then calculated using the standard amortization formula on the total financed amount (original loan plus guarantee fee). This model assumes a fixed interest rate throughout the term. In practice, many SBA loans have variable rates tied to the prime rate that adjust quarterly, which means your actual payments may change over time. The calculator also does not include the annual SBA servicing fee (approximately 0.55% of the guaranteed balance), which lenders typically build into the interest rate.
