How much will a lender actually let my business borrow?
Summary
As much as the lender believes your cash flow can repay, up to the program ceiling. The ceilings are the easy part: SBA 7(a) loans top out at $5 million, SBA Express at $500,000, and microloans at $50,000. The lender's own underwriting decides how close to the ceiling you get, and in the 2025 Fed survey only 42% of small business applicants got everything they asked for.
The ceilings
Standard 7(a) covers loans above $350,000 and up to $5 million; 7(a) Small loans are term loans of $350,000 or less. SBA Express caps at $500,000 in exchange for a smaller guarantee (50% at most), because the lender uses its own procedures and makes the credit decision. The 7(a) Working Capital Pilot is a line of credit that can reach $5 million over a maximum of 60 months. Microloans stop at $50,000, and the average one is about $13,000.
One number sits behind all the 7(a) figures: the SBA's own exposure is capped at $3.75 million in guaranteed dollars. On a $5 million loan the lender carries the rest, which is one reason a lender's appetite for the largest loans is its own, not the program's.
Why SBA's 504 page shows two maximums
The 504 page's subtitle says "up to $5 million." A few paragraphs later it says the maximum is $5.5 million. The regulation, 13 CFR 120.931, explains the gap. The standard limit is an outstanding balance of $5 million for each borrower and its affiliates combined. The $5.5 million figure is a per-project limit for three cases only:
- small manufacturers (NAICS 31 to 33) with all production facilities in the United States
- projects that cut the borrower's energy consumption by at least 10%
- plant, equipment, and process upgrades for renewable energy, such as small-scale power for a building or community, or biodiesel and ethanol production
Because the limit counts outstanding balance, a company already repaying a 504 loan has less room left. And a 504 loan never funds the whole project. The typical structure has a private lender covering up to 50% of the cost, the CDC up to 40%, and the borrower at least 10% in equity. On a $2 million building, the 504 portion is at most $800,000 and the owner puts in at least $200,000.
What decides your number
SBA tells lenders that loans "must be sound with a reasonable assurance of repayment ability." Lenders may look at a business credit score, the credit history of the applicant, its associates, and its guarantors, and also at cash flow, equity, and collateral. Most 7(a) term loans are repaid monthly out of the business's cash flow, so the payment the business can carry sets a real limit well before the program does. A business that clears the ceiling on paper can still be offered less because the monthly payment on the full amount would leave too little margin.
The Fed's 2025 Small Business Credit Survey shows how often requests get trimmed rather than refused. Behind the 42% who got the full amount, 36% received some or most of it, and 22% received nothing. Firms that applied at small banks were fully approved more often, at 57%.
