SBA 7(a) rules at a glance

Key facts

The guarantee
The SBA typically guarantees 75% of 7(a) loans over $150K (SBA SOP 50 10 §6.2) — if the borrower defaults, the SBA pays the lender that fraction back. The guarantee fee is the premium charged for that backstop.
FY2026 guarantee-fee schedule
For long-term loans (over 12 months) the fee on the guaranteed portion is tiered: 2.00% on the first $1M of loan, 3.05% on $1M–$2M, and 3.75% on $2M–$5M. Short-term loans (12 months or less) pay a 0.25% flat fee instead.
Rate caps
Variable 7(a) rates are quoted as Prime + spread, and the SBA caps the lender's spread at 3.0% (13 CFR §120.115(c)) for loans over $350K with terms of 7+ years — higher caps apply to smaller or shorter loans.
Guarantees and collateral
Every loan over $25K requires a personal guarantee from every 20%+ owner regardless of collateral. Loans under $50K have no collateral requirement; $50K–$500K requires business assets but no mandated personal real estate lien (SOP 50 10 §8.2).
Prepayment penalty
Loans with terms of 15+ years carry a prepayment penalty in the first three years if you prepay more than 25% of the balance in any 12-month period: 5% in year 1, 3% in year 2, 1% in year 3, zero thereafter.

What this means

The SBA guarantee fee is real money — on a $500K 7(a) loan with a 75% guarantee, you're looking at $7,500 of fee on top of packaging and closing. That fee is what makes the SBA program work: the lender gets a government-backed 75% floor, which is why they'll give a term and rate you couldn't get conventionally for the same cash flow profile.

The honest comparison is not SBA rate vs conventional rate — it's SBA all-in vs what the lender would actually offer you without the guarantee. In most cases, without SBA the lender either declines or quotes materially worse terms. The $10K–$30K of SBA-related upfront cost is the price of getting a term loan at all, not a tax on getting a better term loan.

Worked example

$500,000 working-capital 7(a) at 10.5% over 10 years. Guaranteed portion: $375,000 at 75%. Guarantee fee: $7,500 (2.00% of the guaranteed portion, since it falls under the $1M bracket). Packaging: $2,500. Closing: $3,500. Total upfront: $13,500. Monthly payment: $6,745. Total interest over 10 years: about $309,400. All-in cost of capital: $822,900 over the life of the loan — or put differently, paying $322,900 on top of the $500,000 you borrowed, in exchange for not needing to post collateral equal to the full loan amount.
