What the fee is buying
The SBA does not lend money; it guarantees a share of loans made by approved lenders. That guarantee is why lenders can offer 25-year terms, moderate down payments and prime-based pricing to businesses conventional underwriting would pass on. The guarantee is also self-funded: the fees lenders pay finance the program’s subsidy cost, which is why the fee tables are revisited every October rather than fixed in statute. For the borrower, the fee is real money, but it is also the price of terms the conventional market rarely offers a small business.
Who pays it, and when
Formally, the lender pays the fee to the SBA. Practically, the lender collects it from you at closing, and loan documents disclose it explicitly. The SBA generally guarantees 85% of loans of $150,000 or less and 75% of larger loans. Confirm current percentages with your lender. The fee applies to that guaranteed portion, which is why fee arithmetic always starts with the guarantee share, not the loan amount.
Why the fee is tiered
Two structures stack. First, the guarantee share itself varies with size: smaller loans carry a higher guarantee percentage, which cushions small borrowers. Second, the fee percentage steps down as loan size rises across published tiers. The net effect: a $150,000 borrower pays a higher rate on a small base, a $3 million borrower pays a lower rate on a large one, and neither pays the fee on the full loan amount.
The tier tables are published each fiscal year. For FY2026 the 7(a) tiers are set out in SBA Information Notice 5000-872051; the 504 program runs a simpler structure at 0.50% upfront on the debenture. Rather than reprint tables that change each October, the guarantee fee calculator computes your exact number from the current file, stamped with its verification date.
Financed or paid at closing
Most borrowers finance the fee: it joins the loan balance and amortizes over the term. That preserves cash on day one and costs a little more overall, because you pay interest on the fee for years. Paying it in cash at closing keeps the balance and payment lower but demands liquidity exactly when closing costs also demand it. Neither is wrong; the honest comparison for a $400,000 loan at a hypothetical 3% fee is roughly $118 more per month financed versus a $9,000 wire at closing.
After closing: service fees and refunds
Two post-closing facts matter. First, ongoing fees: larger 7(a) loans can carry an annual service fee on the guaranteed portion, and the 504 debenture carries its annual service fee; your closing documents list whether yours applies. Second, early payoff: when a 7(a) loan is paid off quickly, a portion of the guarantee fee may be refundable through the lender, with rules that depend on timing. The mechanics are narrow, so ask the lender to spell out the refund terms before closing rather than assuming them.
Getting your exact number
The guarantee fee calculator takes an amount and returns the tiered fee, both financed and paid in cash, with the effect on the payment. The FY2026 fees page tracks what changed this fiscal year and why. Between the two, you should never be surprised by this fee on a closing disclosure.
