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.
