SBA Size Standards Explained | Business Lending Glossary

Definition

The SBA's industry-specific criteria defining what constitutes a "small business" for program eligibility, expressed as maximum number of employees or maximum average annual receipts depending on the industry.

Explanation

To access SBA loan programs, a business must qualify as "small" under the SBA's size standards. These standards are set by industry, classified using North American Industry Classification System (NAICS) codes, and expressed as either a maximum employee count or maximum average annual receipts over the most recent three fiscal years. The standards vary significantly by industry: a manufacturing company might qualify as small with up to 500 or 1,500 employees depending on the specific product, while a retail business might need to have under $30 million or $47 million in annual revenue. Most small businesses comfortably meet SBA size standards — the ceilings are set at levels designed to capture the small and medium business sector, not just micro-businesses. A business with $10 million in revenue in most retail, service, or professional categories is likely to qualify. The size standards become relevant primarily for businesses in scale-up phases that are approaching the ceiling for their industry. Size is measured at the company level, but the SBA's affiliation rules require that the size of affiliated entities — businesses under common ownership or control — be aggregated with the applicant. This aggregation can disqualify businesses that appear small individually but are part of a larger economic group.

Example

A specialty contractor with 85 employees and $12 million in annual revenue wants to apply for an SBA 7(a) loan. Their NAICS code has a size standard of 500 employees. With 85 employees, they are well within the standard. However, if the owner also controls a separate staffing company with 600 employees, the SBA's affiliation rules would aggregate both companies' headcount, potentially disqualifying the contractor from SBA eligibility.

Why It Matters

SBA size standards are a threshold eligibility requirement — businesses that exceed them for their industry are simply ineligible for SBA programs, regardless of creditworthiness. Understanding size standards helps businesses confirm eligibility before investing time in an SBA application. The affiliation rules in particular can create eligibility surprises for business owners with multiple business interests or investor relationships.

Frequently asked questions

Where can I look up the SBA size standard for my industry?

The SBA maintains a Size Standards Tool on their website (sba.gov/size-standards) where you can enter your NAICS code and find the applicable size threshold. The SBA also publishes a Table of Small Business Size Standards as a PDF, which is updated periodically. If you do not know your NAICS code, the US Census Bureau's NAICS lookup tool can help you identify the correct code for your primary business activity. For businesses with multiple activities, the primary NAICS code — the industry generating the most revenue — is typically used.
