Women‑Owned Small Business (WOSB) Set‑Aside Calculator
Eligibility Assessment
What Is the WOSB Set-Aside Calculator?
The WOSB Set-Aside Calculator is a simple tool that determines whether a business qualifies for the U.S. Small Business Administration’s Women-Owned Small Business program based on key criteria.
It checks if your business meets ownership requirements, management control, citizenship status, and size standards based on your industry. It also evaluates optional Economic Disadvantage (EDWOSB) criteria such as personal net worth and average income. This helps business owners understand their eligibility before applying for certification or bidding on government contracts.
The calculator reflects the logic outlined in SBA regulations (13 CFR 127) and gives a quick, practical eligibility assessment. :contentReference[oaicite:0]{index=0}
How the Eligibility Logic Works
The calculator uses a rule-based approach instead of a traditional formula. It evaluates whether your business meets several required conditions.
Each part of the logic checks a specific requirement:
- Ownership ≥ 51%: Women must own at least 51% of the business
- Control: Women must manage daily operations and long-term decisions
- Citizenship: The women owners must be U.S. citizens
- Size Standard: Business must fall within industry-specific limits (revenue or employees)
For EDWOSB status, additional checks apply:
Example:
- A business has 60% women ownership
- Women control management decisions
- Owners are U.S. citizens
- Revenue is $5M in a $23M limit industry
This business qualifies as WOSB. If the owner’s net worth is $400,000 and income is $200,000, it also qualifies as EDWOSB.
Edge cases include businesses under 2 years old. These may still qualify, but some certifiers consider them higher risk.
How to Use the WOSB Set-Aside Calculator: Step-by-Step
- Enter the percentage of ownership held by women (must be 51% or higher).
- Select whether women control daily management and long-term decisions.
- Indicate if the majority women owners are U.S. citizens.
- Enter the number of years your business has been operating.
- Choose your industry to apply the correct size standard.
- Input your business size, either revenue or employee count.
- Optionally, enter net worth and average income for EDWOSB eligibility.
- Click “Check Eligibility” to see your results.
The results will show whether you qualify as a WOSB and, if applicable, as an EDWOSB. It also explains why you may not qualify and what requirements are missing. Use this feedback to fix gaps before applying for certification.
When Should You Use This Calculator?
Before Applying for Certification
Use the calculator to check your eligibility before starting the SBA certification process. It helps avoid delays caused by incomplete or non-compliant applications.
Before Bidding on Federal Contracts
If you plan to bid on WOSB set-aside contracts, this tool helps confirm if your business meets the requirements. This is important because ineligible bids can be rejected.
To Check EDWOSB Advantage
EDWOSB-certified businesses can access additional sole-source contracts. This calculator shows whether you qualify for that extra benefit based on income and net worth limits.
Common Mistakes to Avoid
- Assuming ownership alone is enough without control
- Ignoring industry size standards
- Entering incorrect revenue or employee data
- Overlooking EDWOSB financial limits
Even small errors can lead to disqualification, so accurate inputs matter.
Frequently Asked Questions
What qualifies as a women-owned small business?
A business qualifies as a WOSB if women own at least 51%, control operations, are U.S. citizens, and meet SBA size standards. All conditions must be met at the same time.
How do I know if my business meets size standards?
Size standards depend on your industry. Some use annual revenue limits, while others use employee counts. The calculator applies the correct limit based on your selected industry.
What is the difference between WOSB and EDWOSB?
WOSB requires ownership and control criteria. EDWOSB includes those plus financial limits on net worth and income. EDWOSB offers access to additional contracting opportunities.
Can a startup qualify as a WOSB?
Yes, startups can qualify, but businesses with less than two years of history may face more scrutiny during certification. Some certifiers prefer established operations.
Why does control matter more than ownership?
Ownership alone is not enough. Women must actively manage the business and make key decisions. This ensures the business is genuinely women-led, not just structured that way on paper.
Is this calculator enough for certification?
No, this tool provides a guideline only. Final certification requires formal review by the SBA or an approved third-party certifier with supporting documentation.
