Under SBA's max?

Yes (max 13.00%)

SBA's fee is usually passed on to you; many borrowers pay it from the loan. A variable 7(a) loan of $150,000 can't be priced above 13.00% this month (prime 7.00%). Lenders can charge less, so ask two or three. A variable rate moves with prime, so the payment can change.

Show the math
  • SBA guarantee: 85% of $150,000 = $127,500.00 (85% for loans of $150,000 or less, 75% above)
  • SBA fee: 2% × $127,500.00 = $2,550.00 (loans of $150,000 or less)
  • Monthly payment: $150,000 at 13.00% for 120 months = $2,239.66 (payment = amount × i ÷ (1 − (1 + i)^−120), i = 13.00% ÷ 12); last payment $2,239.96
  • Total interest: $118,759.50; interest + SBA fee = $121,309.50
  • SBA's top variable rate for $150,000: prime 7.00% + 6.00 points = 13.00%. Yours: 13.00% → at or under the cap

Hand check, row 1: SBA guarantees 85% of a $150,000 loan, $127,500. The fee for loans of $150,000 or less is 2% of that: $2,550. The monthly rate is 13% ÷ 12 = 1.0833%, and over 120 months the payment is $150,000 × 0.010833 ÷ (1 − 1.010833^−120) = $2,239.66.

Outside checks: a $2,000,000 loan has a $1,500,000 guaranteed part, so the fee is 3.5% × $1,000,000 + 3.75% × $500,000 = $53,750. A $600,000 loan with a 75% guarantee pays 3% × $450,000 = $13,500. Both match lenders' published examples.

With the prime rate at 7.00% (SBA's Oct. 1, 2026 table). Variable caps are set by law (13 CFR 120.214); SBA posts the fixed caps each month (SBA rate table). These are ceilings: lenders can and often do charge less.
