If you run supplier sourcing or compliance at a prime contractor, you already report a number every year: dollars spent with small and diverse suppliers. That number satisfies your contracting officer. It does almost nothing for your CFO, your board, or a sustainability disclosure.
Spend is an input. Impact is what that spend does once it lands in a local economy: wages paid, jobs supported, output generated, dollars that recirculate. Quantifying that is what separates a program you can defend in a budget review from one that gets cut the next time priorities shift. And after the 2025 rescission of Executive Order 11246, which ended affirmative-action obligations for federal contractors but left statutory set-aside and subcontracting rules untouched, the durable case for a supplier program is economic, not ideological. Here's how to build the measurement.
Start with clean, certified spendYou can't measure impact on a number you can't trust. The base layer is accurate, deduplicated spend categorized by supplier type, and the categorization has to hold up to an audit.
Two certification changes reset the rules on what you can count. SBA eliminated self-certification for service-disabled veteran-owned small businesses; the rule took effect at the start of FY2025, on October 1, 2024. An SDVOSB now has to be certified through SBA's Veteran Small Business Certification program (the VetCert portal at veterans.certify.sba.gov) before its spend counts toward an SDVOSB goal or subcontracting credit. The small disadvantaged business (SDB) category moved the same direction: self-attested SDB status no longer carries the weight it once did, and the credible path is formal certification, most commonly through the 8(a) program.
Practically, that means auditing your supplier master against actual certification records, not a checkbox someone ticked in onboarding three years ago. Verify against the issuing bodies. For federal small-business categories, that's SBA's records and the Small Business Search (the database formerly known as Dynamic Small Business Search, fed from SAM.gov registrations). For corporate certifications like MBE, WBE, and LGBTBE, verify against the certifying council directly; our certifying-bodies directory lists who issues what. Counting an expired or self-claimed certification is the fastest way to lose credibility on the whole report.
Three layers of economic impactOnce the spend is clean, impact analysis breaks it into three layers. This is the same input-output logic the Billion Dollar Roundtable uses in its annual economic impact report, and it's the framing a CFO will recognize.
- Direct impact. The activity at the suppliers you pay. Your $40 million in qualified spend supports the payroll, jobs, and output at those firms directly.
- Indirect impact. What your suppliers buy from their suppliers. A certified manufacturer you pay turns around and buys steel, freight, and software. That second-tier purchasing is real economic activity your dollars set in motion.
- Induced impact. What the wage-earners spend. Employees at your suppliers and their suppliers spend their paychecks on groceries, rent, and healthcare, recirculating the money through the broader economy.
Add the three and you get total economic impact. The ratio of total impact to your original spend is the multiplier. BDR's 2023 reporting put the combined Tier-1 diverse spend of its members at roughly $113 billion in 2022 and the associated direct, indirect, and induced impact near $194 billion, which works out to a multiplier in the neighborhood of 1.7x to 1.8x. Other analyses cite higher figures depending on the model and the industries involved. The point isn't to claim a specific number. It's to express your program in the units that survive a budget conversation: jobs supported and total economic output, not just procurement dollars out the door.
How the multiplier actually gets calculatedThe indirect and induced layers don't come from a spreadsheet you build yourself. They come from an input-output model that maps how dollars move between industries. The standard tool in the US is IMPLAN, which produces multipliers by industry and geography. You feed it your spend by NAICS sector and region; it returns estimated jobs, labor income, value added, and output across all three layers.
You don't need to run IMPLAN in-house to start. The usable version of this is straightforward:
- Segment your qualified spend by NAICS industry and by state or metro. Impact is geographic. A dollar spent with a supplier in a region stays in that region differently than a dollar spent nationally.
- Apply published or modeled multipliers per sector. A services-heavy spend profile and a manufacturing-heavy one produce different job and output numbers from the same dollar total.
- Report jobs supported, labor income, and total output, with your methodology stated plainly so the numbers are defensible.
State the assumptions. An impact figure with a named model and a clear method behind it reads as analysis. A bare multiplier with no source reads as marketing, and a sharp reviewer will treat it that way.
Tie it to the compliance reporting you already oweIf you hold federal prime contracts, you're filing subcontracting reports regardless. Build the economic-impact analysis on the same data so you're not maintaining two systems.
The mechanics: under FAR 52.219-9, a prime contract expected to exceed the subcontracting-plan threshold with subcontracting possibilities requires an accepted small-business subcontracting plan. Those thresholds rose on October 1, 2025, to $900,000 for most contracts and $2 million for construction (up from $750,000 and $1.5 million). FAR 19.702 carries the statutory basis. You report performance against that plan through the Electronic Subcontracting Reporting System (eSRS), filing the Individual Subcontract Report (ISR) per contract and the Summary Subcontract Report (SSR) covering an agency or government-wide, both on the federal fiscal-year cycle.
Those reports already capture spend by category against your committed goals, which roll up to the government-wide statutory targets: 23% of prime dollars to small business, with sub-goals of 5% for small disadvantaged business, 5% for women-owned small business, 5% for service-disabled veteran-owned small business (raised from 3% by the FY2024 NDAA), and 3% for HUBZone. The eSRS data set is the cleanest, most defensible spend ledger you have, because it's already categorized and already audited. Run your impact model on top of it and the economic story inherits that credibility.
If your pipeline of certified subcontractors is thin, that's a sourcing problem, and SBA built tools for it. Post opportunities to SBA's SUBNet so certified small firms can find your subcontracts, and search the Small Business Search for qualified suppliers by NAICS and location before you claim a goal is unreachable. Our supplier directory lets you search certified diverse and small suppliers across categories in one place.
Report it for ESG and CSRD, not just the contracting officerThe same impact analysis does double duty in sustainability disclosure. The EU's Corporate Sustainability Reporting Directive (CSRD) pulls supply-chain and social-impact data into mandatory reporting for in-scope companies, and US multinationals selling into Europe are inside that scope. Supplier-program economic impact, local sourcing, and jobs supported map directly onto the social pillar of ESG frameworks.
The discipline that makes a federal subcontracting report audit-ready is the same discipline a CSRD assurance provider expects: verified supplier status, spend traceable to source, methodology stated. Build it once. A program expressed as "$40 million in qualified spend supporting roughly X jobs and $Y in regional output, verified against SBA and council certification records" is a number that holds up in a board deck, a sustainability report, and a contracting officer's review. "We spent some money with diverse suppliers" holds up in none of them.
For benchmarking, the companies that publish billion-dollar diverse-spend figures show what a mature program reports and how they frame the impact. We track them in the 43 companies spending $1 billion or more with diverse suppliers. If you want to find and vet the suppliers and corporate programs behind those numbers, start with our corporate program directory and the supplier directory.
Measure the impact, source the suppliers to back it, and the program defends itself.
