How this measured rate is calculated
Every observation converts the crew’s shared clock time into cleaner-hours first:
Then the task’s rate is:
For example, if two cleaners complete 3,000 sq ft in 30 shared minutes, they used 1 cleaner-hour in total (2 × 30 ÷ 60). That one hypothetical observation gives 3,000 sq ft per cleaner-hour. It is an arithmetic example, not a recommended or typical industry rate.
Compare like with like
The summary combines records only when task name, unit and conditions profile match. Use a specific, repeatable task name and describe factors that change the work, such as floor type, equipment, soil level, furniture, access and finish standard. If a meaningful condition changes, start a different profile rather than blending the rates. The tool matches the text you enter; it cannot verify that two jobs were truly comparable.
Measure the same task boundary each time. Count all cleaners who worked on the quantity and the elapsed minutes while they were doing that task. Keep travel, breaks, setup, interruptions and other work separate unless you consistently include them in the same task definition. Do not count the crew’s clock minutes only once: two cleaners working for 30 minutes use 60 cleaner-minutes.
Read the summary carefully
The weighted rate is total quantity divided by total cleaner-hours across the matching observations. It gives longer jobs more weight than short jobs. The individual-observation range shows the lowest and highest rates in that group, and the count shows how many records contributed. A small or inconsistent sample can be misleading; inspect the underlying rows and conditions before you use a rate.
This tool does not remove outliers, grade cleaning quality, measure productivity independently or establish an industry standard. Your records describe your jobs, crew, equipment and chosen task boundaries only. Use your judgment and local requirements.
Use a rate in a time estimate
Choose the matching units and enter this group’s weighted rate as units per cleaner-hour in the commercial cleaning time calculator. Keep the task label, profile and observation count in your rate book so you can review why you chose it. The time calculator turns quantities into planned labor; it does not guarantee the crew’s actual finish time. Add labor costs and other expenses separately in the price calculator.
