In-House vs Contract Cleaning Cost Calculator
Formula
How to use the result
Compare equivalent scope, frequency, quality, consumables, equipment, supervision, escalation clauses and exclusions before treating the lower total as the better option.
What the calculator does not know
This site addresses ordinary commercial-cleaning planning only. It does not provide chemical-mixing instructions, hazardous-material cleanup, infection-control protocols, biohazard procedures, work-at-height instructions or equipment-operation training. Follow product labels and safety data sheets, workplace rules, applicable law and qualified specialist guidance.
Improve the estimate
Keep the inputs used for the decision and compare the estimate with actual results. A simple calculator is most useful when it makes the assumptions visible enough to learn from the difference.
