SBA Loans: the lowest rates and longest terms — with more paperwork

SBA-backed loans carry some of the lowest rates and longest terms available to small businesses, because a government guaranty reduces the lender's risk. The trade-off is documentation and time.

SBA 7(a) maximum rates by loan size

The SBA caps what lenders can charge as the prime rate plus a maximum spread that shrinks as the loan gets larger. At the current 6.75% prime rate:

Loan sizeMaximum rate
$50,000 or lessPrime + 6.5% = 13.25%
$50,001–$250,000Prime + 6.0% = 12.75%
$250,001–$350,000Prime + 4.5% = 11.25%
Over $350,000Prime + 3.0% = 9.75%

For real estate and major equipment, the SBA 504 program's CDC portion runs roughly ≈5.6%–6.0% on 10–25 year terms — among the cheapest financing a small business can get in 2026.

SBA lending in 2026

The programs had a record year: in fiscal 2025, SBA 7(a) and 504 approved 84,840 loans totaling $45.1 billion, with the average 7(a) loan around $477,642. More than half of all 7(a) loans were under $150,000, so SBA isn't only for large borrowers.

SBA vs. a line of credit or online term loan

SBA wins on

  • Rate — often the lowest available
  • Term length — longest amortization
  • Large amounts and real estate

Faster options win on

  • Speed — a line of credit funds in days
  • Less paperwork
  • Lower credit thresholds

What credit score do you need?

There's no single SBA-wide minimum, but lenders generally look for solid personal and business credit, at least two years in business, and the ability to repay. Checking your options through WithFunded uses a soft credit inquiry with no impact on your score.

Frequently asked questions

What credit score do I need for an SBA loan?
The SBA doesn't set one fixed minimum, but participating lenders typically look for strong personal and business credit along with at least two years in business and demonstrated repayment ability.
How long does an SBA loan take to fund?
Weeks to a few months. The government guaranty that lowers your rate also adds underwriting steps, so SBA is slower than online term loans or lines of credit.
How much can I borrow with an SBA 7(a) loan?
Up to $5 million. In practice the average 7(a) loan in fiscal 2025 was about $477,642, and more than half were under $150,000.
Are SBA rates really capped?
Yes. The SBA sets maximum rates as prime plus a spread that decreases with loan size — currently 9.75% to 13.25% at a 6.75% prime rate. Many borrowers qualify below the maximum.
