Grants Math Pro · Bedrocka Tools
Grant math without the consultant pitch.
Most grant eligibility tools are run by consultants, grant writers, or platforms with a finder's fee on the award. This site is the opposite: every formula is open-source, every eligibility threshold cites the primary source (SBA size standards, SBIR/STTR regulations, CFDA, Grants.gov), and every tool is reviewed by a named operator. Built for small business owners and founders navigating SBIR/STTR, SBA programs, federal grants, and state incentives.

Concepts behind the grant math.
SBIR / STTR
SBIR eligibility: the complete guide for small business owners
SBIR awards $4B/yr but most small businesses fail the eligibility gate before they even write a proposal. This is the policy-directive-cited eligibility checklist.
Federal Grants
Federal grant cost-share requirements explained (2 CFR Part 200)
In-kind match, third-party contributions, and cost-sharing ratios under 2 CFR Part 200 — the Uniform Guidance rules that govern every federal grant's matching requirements.
What makes this different
Three things every Bedrocka Tools site does that the grant-consultant mills don't.
Open-source math
Every calculator's formula is published as TypeScript with Vitest tests in a public repo. Click "View source" in any math accordion to see the actual implementation. Most grant eligibility tools are proprietary black boxes built to funnel you to a paid consultant. We publish ours.
Browse the math →Primary-source citations only
Every eligibility threshold, size standard, and cost-share requirement links to the original document — SBA SBIR/STTR Policy Directive (2020), 13 CFR Part 121 size standards, 2 CFR Part 200 Uniform Guidance, Grants.gov, CFDA. No "generally speaking" hedging. The citation is the proof.
Read the methodology →Named operator, no finder's fee
Reviewed and signed by Byron Malone— operator-author who has navigated federal grant programs on his own ventures. Not a grant consultant. Not a platform with a finder's fee on the award. Nothing here earns a commission tied to your application.
