About HomeCalcify
Free, accurate estimating tools for homeowners, DIYers, and contractors — built and reviewed by people who do this work.
HomeCalcify exists to answer one question that starts almost every home improvement project: how much material do I actually need? Guessing wastes money and time — either you over-order and eat the cost, or you run short mid-job. Our calculators replace the guesswork with fast, reliable math.
What we do
We build free calculators for concrete, roofing, flooring, tile, paint, drywall, mulch, and paving — with more added every month. Each tool gives you quantities, material counts, and a cost estimate, and every page explains the formula so you can check the work yourself.
How we keep estimates accurate
Every calculator's formula is documented and reviewed by experienced tradespeople. We use industry-standard coverage rates, waste factors, and conversions, and we update tools as materials and best practices change. See our methodology for the full picture, and our expert reviewers for who checks the numbers.
Who we serve
- Homeowners planning a weekend project or a major renovation.
- DIYers who want to buy the right amount the first time.
- Contractors and estimators who need a fast second opinion on quantities.
A note on estimates
Our tools produce close estimates for planning and budgeting. Site conditions vary, so always confirm critical quantities with your supplier or a licensed professional before ordering. Read our disclaimer for details.
