Why MatCount
Instant answers
No forms, no accounts, no waiting. Type your numbers and the result updates as you go.
Private by design
Everything runs on your device. Nothing you type is uploaded or stored on a server.
Built for real jobs
Waste allowances, bag counts and box counts — the numbers you actually buy by, not just raw volume.
Buy the right amount, the first time
The most expensive mistakes on a home project happen at the store, not on the job. Buy too little concrete and your pour has a weak cold joint; buy too little tile and the next batch doesn't match; run out of paint halfway up a wall and you get lap marks that never fully hide. Buy too much and you've tied up money in materials you'll never use.
MatCount exists to make that math trivial. Each calculator asks for the few measurements that matter, adds the waste allowance the pros use, and gives you the answer in the units you actually purchase in — cubic yards and bags, tiles and boxes, gallons. Pick a calculator above to get started.
