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.

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.
Federal Grants & SBIR
Complete Guide to Small Business Grants 2026
Free money has a cost — in compliance time, reporting burden, and clawback risk if you miss milestones. Here's the honest map of the 2026 grant landscape, who actually qualifies, and what it takes to run a successful application.

SBIR/STTR Application Strategy 2026
SBIR's 15–25% acceptance rate looks daunting until you understand the agency selection, topic matching, and scoring breakdown that separate winning proposals from the majority that don't get funded.
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.
