About Grants Math Pro

Grants Math Pro is a property of Bedrocka Tools — the calculator that shows its work. Grant eligibility and cost calculators for SBIR/STTR programs, federal grant cost-share requirements, SBA size standards, and state business grant ROI — without the consultant pitch.

Every calculator on this site is built on three pillars:

• Open-source math— every formula is published under MIT license on GitHub so you can audit, fork, and verify.
• Primary-source citations— every assumption is cited to a government publication, statute, or authoritative primary source.
• Named-author accountability— Byron Malone is the named editor and author. Every page has a real human accountable for the work.
