About Renovation Math Pro
Renovation Math Pro is a property of Bedrocka Tools — the calculator that shows its work. Renovation cost calculators for project ROI, home equity financing comparison, resale value uplift, and project budget planning — without the contractor 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.
