Self-Leveling Compound Calculator
Self-leveling compound evens out a floor before tile or vinyl goes down. This estimates the bags you need from the area, the depth you pour and the yield printed on the bag.

How it works
Volume is area times depth. A small allowance is added for spills and low spots. The volume is then divided by the yield printed on one bag, and rounded up to whole bags.
Depth is often thin, around an eighth of an inch, or about 3 millimetres. Patches and low spots may need more. Yield differs by product, so read the label and enter that figure.
Worked example
A floor of 150 ft², poured 0.125 in deep, needs 1.64 ft³ of mix, which is 5 bags at the yield you entered.
Questions
Can it be poured thicker?
Some products can go thicker and some cannot. Check the label for the maximum depth before you pour.
Does the yield include waste?
No. The yield is what one bag makes. The allowance for spills is added here.
Why do low spots need more?
Low spots pull in more mix than a flat area, so a small patch can use a noticeable share of a bag.
