Concrete, mulch, lumber and tile estimators for projects
Construction and DIY projects require accurate material estimates to avoid costly over-ordering or frustrating mid-project supply runs. Our estimators cover concrete, mulch, lumber, and tile calculations based on the dimensions of your project. Each tool accounts for waste factors and industry-standard coverage rates.

Estimating Concrete for a Slab
Concrete is sold by the cubic yard in the United States and by the cubic meter in most other countries. To calculate how much you need for a slab, multiply the length by the width by the depth (all in the same unit), then convert to cubic yards or meters. Our estimator also tells you how many 60-pound or 80-pound bags of premixed concrete that translates to for smaller projects.
