Commercial cleaning
Cleaning quality rework cost
Measure actual repeat-work cost and margin erosion per contract.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
rework labor+travel+supplies; erosion=rework/contract revenue.
Repeat-work costs are additional to the original accepted-work budget. Erosion is percentage points of contract margin, not percent change in original profit. No chemical dosing.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Repeat-work labor in period (person-hours): ADDITIONAL period repeat-work person-hours.
- Loaded repeat-work labor cost (selected currency): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for loaded repeat-work labor cost. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
- Total repeat-work travel cost (selected currency): TOTAL repeat-work travel expense for the period.
- Total repeat-work supplies cost (selected currency): Matching invoice, quote, statement, bookkeeping record or explicit budget amount for total repeat-work supplies cost. Use the stated period and exclude amounts already counted in another field. Zero means intentionally excluded/not incurred, not unknown.
- Contract revenue in same period (selected currency): Matching period contract revenue; erosion is percentage points of margin.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Repeat-work cost is $650.00 for the illustrative inputs below.
Example inputs
- Repeat-work labor in period: 20.00 person-hours
- Loaded repeat-work labor cost: $25.00
- Total repeat-work travel cost: $100.00
- Total repeat-work supplies cost: $50.00
- Contract revenue in same period: $5,000.00
- Repeat-work cost
- $650.00
- Contract margin erosion
- 13.00 %
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Measure actual repeat-work cost and margin erosion per contract.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
