Accuracy Policy

We take correctness seriously. Each tool uses standard, published formulas, and we test them against known cases.

Estimates

Real-world results (paint coverage, flooring waste, shipping weight, interest) depend on factors we can't fully capture. Treat outputs as good-faith estimates and add a safety margin where it matters.
