Grout estimate formula

Tile count = area ÷ tile face area

Joint volume ≈ tile count × tile perimeter × joint width × joint depth

Grout bags = grout weight × (1 + waste %) ÷ bag size

Example

A 120 ft² floor with 12×24 in tile, 0.125 in joints, 0.375 in joint depth, and 10% waste needs about one 25 lb bag in this quick estimator.Use metric area with the same joint logic, then compare the result to the manufacturer coverage chart for your grout type.

Grout Calculator FAQ

How does this grout calculator work?+

It multiplies measured job dimensions by the coverage, spacing, or package yield you enter, adds waste, then rounds the buy quantity up. This gives a field estimate. Grout brand coverage charts are the final authority.It multiplies measured job dimensions by the coverage, spacing, or package yield you enter, adds waste, then rounds the buy quantity up.

Should I use the default waste value?+

Use the default for a quick planning estimate, then raise it for cuts, odd layouts, breakage, bad access, or product-specific loss.Use the default for a quick planning estimate, then raise it for cuts, odd layouts, breakage, bad access, or product-specific loss.
