How to Use This Calculator

Enter the total floor area requiring leveling in square feet.
Measure the maximum depression (deepest low spot) with a 6-foot straightedge and enter in inches.
Enter the average depression depth across the floor.
Enter the self-leveling compound coverage rate and bag weight from the product label.
Review the estimated bags needed, compound volume, and total weight to plan material orders.

How the result changes with Bag Weight

Floor Area: Total floor area requiring leveling.
Maximum Depression: Deepest low spot measured with a straightedge.
Average Depression: Average depth of depressions across the floor.
Compound Coverage: Coverage per bag at 1/8 inch depth (check product label).
Bag Weight: Weight of each bag of self-leveling compound.
