About us
Estimetra is a calculation + quoting toolkit for self-employed contractors and small site crews: painters, tilers, drywallers, masons and remodelers.
Promise: the free tool answers with no signup; the account saves customers, prices and quotes so you repeat faster.
We invent no credentials or testimonials: we publish formulas, assumptions and verification dates.
How we check the maths: every calculator publishes its formula, a worked numeric example and its assumptions (coverage rates, waste factors, sale formats), taken from manufacturer data sheets and dated in Methodology. The calculation engines are deterministic and covered by automated tests.
Found a mistake? Email hola@estimetra.com with the calculator, your inputs and your source: we review it and, where needed, fix the formula and log the change in Methodology.
Design and development: Srikanta M.
