Concrete Leveler Calculator
This concrete leveler calculator converts floor area and average pour depth into self-leveling compound bags. The trick with any concrete leveling calculator is the average depth — levelers feather from zero to the low spot's full depth.

Die Formel
Volume = area × average depth; bags = volume ÷ 0.44 ft³ per 50 lb bag (+10% waste) Rechenbeispiel: 200 ft² at an average 1/4 in depth: 200 × 0.0208 = 4.2 ft³ → ≈ 11 × 50 lb bags with waste.
Find average depth honestly: map the floor with a straightedge or laser, note the deepest dips, and average across the whole area — a floor that's flat except one 1-inch dip over 10% of the area averages just 0.1 inch.
One 50 lb bag of self-leveling underlayment yields about 0.44 ft³ — enough to cover 50 ft² at 1/8 inch or 12 ft² at 1/2 inch. Deep fills (over 1 inch) usually allow extending the mix with pea gravel; check your product's spec.
Leveler sets in minutes, so bag count discipline matters: stage all bags, water and mixing barrels before starting, and pour the whole area in one continuous operation.
Häufig gestellte Fragen
Häufige Fragen zum concrete leveler calculator.
How many bags of self-leveler do I need?
Area × average depth ÷ 0.44 ft³ per 50 lb bag. 100 ft² at 1/4 in average ≈ 5 bags before waste.
How do I find the average depth?
Check the floor with a straightedge and laser at a grid of points; average the readings. Most 'wavy' floors average 1/8–3/8 inch.
How thick can self-leveler go?
Typically 1/8 in feather-edge up to 1–2 in neat, and up to 5 in extended with aggregate — always per the specific product's data sheet.
Is self-leveler the same as concrete?
No — it's a cement-based underlayment for flatness, not a structural wear surface. Top it with flooring or use a topping mix for exposed surfaces.
