DIY Material Calculator

Plan your next home project with DIY Material Calculator. Estimate paint, flooring and concrete quantities from your own measurements, coverage rates and waste allowance, with a visible breakdown of how each estimate was calculated.

FLOORING ESTIMATES
Enter room length and width, choose your measurement unit and add a waste percentage. Add coverage per package to estimate a rounded-up package count, or leave it blank for area only.

PAINT ESTIMATES
Use wall perimeter and height, subtract openings, and set the number of coats. Enter your paint's coverage rate and container size to estimate liters and container quantities. Defaults are editable planning assumptions, not manufacturer guarantees.

CONCRETE ESTIMATES
Enter length, width and depth for volume calculations. Add a waste allowance and, if needed, your mix's stated bag yield to estimate the number of bags.

KEEP YOUR PROJECT CALCULATIONS
Name and save calculations on your device, reopen them when planning the next step, and archive records you no longer need. Adjust measurement preferences, decimal places and default waste settings.

FREE TO USE, WITH OPTIONAL AD REMOVAL
The core calculator is free and ad-supported. An optional one-time lifetime purchase removes ads; there is no subscription. Purchase and restore are handled through Google Play. Advertising services may process data as described in the privacy policy and store disclosures.

PLANNING ESTIMATES ONLY
Verify your measurements, units, coverage and yield against product instructions and actual site conditions. Results can vary with materials, installation methods and surface conditions. This app is not structural, engineering, building-code or safety guidance.
