Commercial Building Square Footage Cleaning Time Estimator
Estimate the total cleaning time for a commercial building based on square footage, building type, cleaning frequency, and crew size.
Total Square Footage (sq ft)
Building Type
Office Building (general) Medical / Healthcare Facility Retail Store Warehouse / Industrial Restaurant / Food Service School / Educational Facility Hotel / Hospitality Government / Municipal Building
Cleaning Frequency
Daily Every Other Day Weekly Bi-Weekly Monthly (deep clean)
Number of Restrooms
Crew Size (number of cleaners)
Number of Floors
Calculate Cleaning Time
function comCalc() { var sqft = parseFloat(document.getElementById('com-sqft').value); var baseRate = parseFloat(document.getElementById('com-type').value); var freqFactor = parseFloat(document.getElementById('com-freq').value); var restrooms = parseInt(document.getElementById('com-restrooms').value) || 0; var crew = parseInt(document.getElementById('com-crew').value); var floors = parseInt(document.getElementById('com-floors').value); var resultDiv = document.getElementById('com-result');
// --- Input Validation --- if (isNaN(sqft) || sqft Please enter a valid square footage (minimum 100 sq ft).'; return; } if (isNaN(crew) || crew Crew size must be at least 1.'; return; } if (isNaN(floors) || floors Number of floors must be at least 1.'; return; } if (restrooms Number of restrooms cannot be negative.'; return; }
// --- Core Formula --- // Base cleaning time (hours) = Square Footage × Base Rate (hrs/sq ft) var baseTime = sqft * baseRate;
// Frequency adjustment: less frequent = deeper clean = more time per visit var adjustedTime = baseTime * freqFactor;
// Restroom time: each restroom adds ~20 minutes (0.333 hrs) per cleaning var restroomTime = restrooms * 0.333;
// Floor transition penalty: each additional floor adds 5 minutes (0.083 hrs) travel/setup var floorPenalty = (floors - 1) * 0.083;
// Total solo time (hours) var totalSoloTime = adjustedTime + restroomTime + floorPenalty;
// Divide by crew size for actual elapsed time // Apply a crew efficiency factor: each additional cleaner is ~90% as efficient // Efficiency = 1 - 0.10 * (crew - 1), floored at 0.60 var efficiency = Math.max(0.60, 1 - 0.10 * (crew - 1)); var totalTime = totalSoloTime / (crew * efficiency);
// Convert to hours and minutes var hours = Math.floor(totalTime); var minutes = Math.round((totalTime - hours) * 60);
// Annual estimate (assume 260 working days / year for daily; scale by frequency) var freqDaysPerYear = { "1.0": 260, "0.85": 130, "0.75": 52, "0.65": 26, "0.55": 12 }; var freqKey = document.getElementById('com-freq').value; var daysPerYear = freqDaysPerYear[freqKey] || 260; var annualHours = totalTime * daysPerYear;

#### Formula
Step 1 – Base Time: Base Time (hrs) = Square Footage × Base Rate (hrs/sq ft)
Step 2 – Frequency Adjustment: Adjusted Time = Base Time × Frequency Factor (Less frequent cleaning requires more thorough work per visit)
Step 3 – Add Restroom & Floor Time: Restroom Time = Number of Restrooms × 0.333 hrs (20 min each) Floor Penalty = (Floors − 1) × 0.083 hrs (5 min per floor transition) Total Solo Time = Adjusted Time + Restroom Time + Floor Penalty
Step 4 – Crew Adjustment: Crew Efficiency = max(0.60, 1 − 0.10 × (Crew − 1)) Elapsed Time = Total Solo Time ÷ (Crew Size × Crew Efficiency)
Step 5 – Cost Estimate: Cost Per Visit = Elapsed Time × Crew Size × $18/hr Annual Cost = Cost Per Visit × Visits Per Year
