Work out cleaning cost per square foot instantly with clear inputs, formula shown and shareable results.
Cleaning is benchmarked both by cost per square foot and by area per cleaner, and the second explains the first. A general office cleaner covers 10,000 to 14,000 square feet per shift; specification changes such as daily desk cleaning or more washroom checks cut that coverage and raise cost proportionally.
Cleaning benchmarks
Cost per ft² = annual cost / cleanable area; area per cleaner = cleanable area / staff
Cost per ft² = annual cost / cleanable area; area per cleaner = cleanable area / staff. Cleaning is benchmarked both by cost per square foot and by area per cleaner, and the second explains the first.
Plant rooms, risers and voids are not cleaned but do count in gross area. Including them understates the true cost per cleaned square foot and makes benchmarks incomparable.
This calculator takes 4 inputs: Annual cleaning cost, Cleanable area, Cleaning days per year, Cleaning staff. The pre-filled defaults are a realistic worked example — replace them with your own site or project figures.
