Formula Submission & Verification Process
When reporting mathematical discrepancies or submitting new formulas for inclusion in our calculators, please include relevant technical references such as ANSI, ASTM, or IRC code citations, manufacturer specification PDFs, and physical test data.

Frequently Asked Support Questions
Are CraftCalc calculators free for professional commercial estimators?
Yes, 100% of our calculation tools, formula matrices, and printable cheat sheets are completely free to use for both DIY homeowners and professional general contractors preparing client bids.
How do you account for regional building code differences?
Our baseline algorithms reflect International Residential Code (IRC) standards. When regional variations exist (such as frost line depth or seismic strapping), our tools provide adjustable input sliders for localized job site customization.
Can I request a custom calculation tool for my specialty trade?
Absolutely. If your trade requires custom dimensional takeoffs (such as HVAC duct sizing, electrical load balancing, or specialized roofing pitch multipliers), email our editorial team with your specification sheets.
