Floor Leveling Compound Calculator

Estimate the amount of self-leveling compound needed to level a floor based on the area and pour depth.

Room Length (ft)

Room Width (ft)

Pour Depth (inches)

Bag Coverage (sq ft per bag at 1/8 inch depth)

Waste Factor (%)

Calculate

function floCalc() { var length = parseFloat(document.getElementById('flo-length').value); var width = parseFloat(document.getElementById('flo-width').value); var depth = parseFloat(document.getElementById('flo-depth').value); var coverage = parseFloat(document.getElementById('flo-coverage').value); var waste = parseFloat(document.getElementById('flo-waste').value);

var errors = []; if (isNaN(length) || length 2) errors.push("Pour depth must be between 0.0625 and 2 inches."); if (isNaN(coverage) || coverage 50) errors.push("Waste factor must be between 0% and 50%.");

var resultDiv = document.getElementById('flo-result'); if (errors.length > 0) { resultDiv.innerHTML = '' + errors.join('') + ''; return; }

// Core formula: // Area (sq ft) = length × width // Coverage per bag at given depth = coverage_at_1_8in × (0.125 / depth_in_inches) // because coverage scales inversely with depth // Net bags needed = Area / coverage_per_bag_at_depth // Total bags (with waste) = net_bags × (1 + waste/100), rounded up

var area = length * width; var coverageAtDepth = coverage * (0.125 / depth); var netBags = area / coverageAtDepth; var totalBags = netBags * (1 + waste / 100); var bagsRounded = Math.ceil(totalBags);

// Volume in cubic feet and cubic yards var volumeCuFt = area * (depth / 12); var volumeCuYd = volumeCuFt / 27;

// Weight estimate: typical self-leveling compound ~100 lbs per 50 lb bag // Standard bag is 50 lbs; weight = bagsRounded × 50 var weightLbs = bagsRounded * 50;

resultDiv.innerHTML = '### Results ' + '' + 'Floor Area' + '' + area.toFixed(2) + ' sq ft' + 'Pour Volume' + '' + volumeCuFt.toFixed(3) + ' cu ft (' + volumeCuYd.toFixed(4) + ' cu yd)' + 'Coverage per Bag at ' + depth + '"' + '' + coverageAtDepth.toFixed(2) + ' sq ft' + 'Net Bags Needed' + '' + netBags.toFixed(2) + ' bags' + 'Bags with ' + waste + '% Waste' + '' + totalBags.toFixed(2) + ' bags' + '📦 Bags to Purchase (rounded up)' + '' + bagsRounded + ' bags' + 'Estimated Weight (50 lb bags)' + '' + weightLbs.toLocaleString() + ' lbs' + ''; }

#### Formula

Area = Length (ft) × Width (ft) Coverage per bag at given depth = Coverage1/8″ × (0.125 ÷ Depth)   — Bag coverage is rated at 1/8″ (0.125″); coverage scales inversely with depth. Net bags = Area ÷ Coverage per bag at depth Total bags (with waste) = Net bags × (1 + Waste% ÷ 100) Bags to purchase = ⌈ Total bags ⌉  (ceiling / round up) Pour volume (cu ft) = Area × (Depth ÷ 12)
