What this calculates
Enter your bag's rated coverage, the number of bags you have (or plan to buy), and your pour depth to see the total area they'll cover.
Estimated Coverage
–Coverage per Bag at Your Depth
–Total Area Covered
Estimates are approximate. Always verify coverage using the specific manufacturer's technical data sheet.
How This Differs From the Material Calculator
The material calculator starts from your room dimensions and tells you how many bags to buy. This tool works the other way: if you already know how many bags you have, it tells you how much floor area they'll actually cover at your planned depth — useful for checking whether you have enough material on hand before you start mixing.
