Worked example
Search 541511, Custom Computer Programming Services. The limit is $34 million in average annual receipts. A programming firm averaging $20 million has $14 million of headroom and is within the standard. One averaging $36 million is over it. Now search 332710, Machine Shops: the limit there is 500 employees, so receipts do not matter.
How to read the result
Each limit is the maximum a concern and its affiliates can have and still be small. Revenue standards are in millions of dollars of average annual receipts. Employee standards count the average number of employees. A few industries use another measure, for example banks are measured by assets. A footnote marker means the regulation adds a condition; the full footnote text appears under the result.
How receipts and employees are averaged depends on the program. See 13 CFR 121.104 (annual receipts), 121.106 (employees), 121.103 (affiliation) and 121.107 (primary industry). The “check your size” box compares one figure to the listed limit; it does not apply those rules for you.
Source and date
The table is a static snapshot of 13 CFR 121.201 taken from the eCFR current text, which was up to date as of 29 September 2026. Per the eCFR version history, the section was last amended on 17 March 2023. It uses 2022 NAICS codes. SBA publishes the same standards in its size standards guide. Rules change, so confirm the current text before relying on a number.
Frequently asked questions
What is an SBA size standard?
It is the largest a business can be, by average annual receipts or number of employees depending on the industry, and still count as small for SBA programs.
Does this page decide whether my business is small?
No. It reads the published limit for one NAICS code. Affiliates, averaging periods and program-specific rules also matter, so confirm with SBA or a procurement officer.
Why do some NAICS codes appear twice?
The regulation lists a few exceptions, such as 562910 Environmental Remediation Services, with their own standard and footnote. Each is shown as its own row.
