Calculate how many bags of self-leveling compound you need for floor preparation. Enter area and depth to get bag count with yield automatically adjusted for your pour thickness.
Part of the Surfaces & Finishes calculators — see all tools in this category.
Total area to be leveled
Common depths: 1/8" (0.125), 1/4" (0.25), 1/2" (0.5)
Typical: 10% for mixing losses and minor errors
Check product label for coverage specs. Default: 40 sq ft per 50 lb bag at 1/8" depth.
Product coverage per bag at the reference depth
Depth at which coverage is specified (usually 1/8" = 0.125)
This calculator helps you determine how many bags of self-leveling compound to purchase for floor preparation, automatically adjusting coverage based on your actual pour depth.
Formula: Adjusted Yield = Reference Yield × (Reference Depth ÷ Actual Depth)
Bags Needed = Floor Area ÷ Adjusted Yield × (1 + Waste%)

Calculate how many liters of paint you need for walls, ceilings, and trim using room dimensions, coat count, and standard coverage rates.
Tile Calculator
Work out how many tiles to order for floors and walls, with waste factors adjusted for grid, diagonal, and herringbone patterns.
Flooring Calculator
