Use examples to understand the method
Every dollar amount, duration and building size below is hypothetical. These are not market rates or production benchmarks. Replace them with your own site assessment and business costs.
Each example uses a $25 loaded hourly labor cost and a 25% target margin. Travel combines paid travel labor with vehicle expense, matching the calculator’s single Travel field.
| Per-visit input | Office A | Office B | B: initial clean |
|---|---|---|---|
| Cleanable area | 2,000 sq ft | 4,000 sq ft | 4,000 sq ft |
| Cleaners × hours each | 1 × 2 | 2 × 2 | 2 × 4 |
| On-site labor | $50 | $100 | $200 |
| Supplies | $6 | $8 | $18 |
| Travel | $17.50 | $18.50 | $21.50 |
| Overhead | $16.50 | $23.50 | $45.50 |
| Total costs | $90 | $150 | $285 |
| Price at 25% margin | $120 | $200 | $380 |
The same area can mean different work
Each price equals total entered cost divided by 0.75. The third scenario assigns more work to the same area, showing why square footage cannot establish a price by itself.
Document the tasks behind each scenario. A proposal should identify frequency, included work, optional additions and who supplies products or equipment.
A monthly average is not an invoice
For planning, a hypothetical $200 visit performed twice weekly throughout a 52-week year gives:
$200 × 2 × 52 ÷ 12 = $1,733.33 per month.
This is an annualized average, not an invoice schedule. If you bill by visit, use the actual scheduled visits and agreed terms. Holidays and changes in service can affect the schedule.
Turn a scenario into a clear scope
For Office B, the recurring scope might include accessible floors, agreed waste bins, restroom fixtures and breakroom counters on each scheduled visit. The initial clean could add work for existing buildup. These task lists are hypothetical; they do not establish that two or four hours is enough for an actual building.
A walkthrough should identify floor finishes, occupancy, fixture counts, access restrictions and who supplies consumables. Give periodic tasks their own frequency. Do not quietly include a monthly task in every visit’s time or assume a first clean costs the same as maintenance.
Record those details in a printable quote. For wider context, read how costs affect commercial-cleaning rates.
Use the commercial cleaning checklist to assign routine and periodic work to the right visit and record any unfinished tasks.
Review a completed visit
Take Office B’s recurring estimate as the original snapshot: four cleaner-hours, $150 cost and $200 selling price. Suppose one cleaner records 2.75 hours and another records 2.5 hours. Actual labor is 5.25 cleaner-hours, not the longer person’s 2.75 hours.
| Review item | Original estimate | Completed visit |
|---|---|---|
| Total cleaner-hours | 4 | 5.25 |
| Labor at $25 per hour | $100 | $131.25 |
| Supplies + travel + overhead | $50 | $50 |
| Total entered costs | $150 | $181.25 |
| Fixed selling price | $200 | $200 |
| Amount after entered costs | $50 | $18.75 |
| Margin after entered costs | 25% | 9.375% |
The extra 1.25 cleaner-hours cost $31.25. To model a 25% margin on $181.25 of costs, the price would need to be $181.25 ÷ 0.75 = $241.67, rounded. That comparison does not change the customer’s agreed $200 price.
Try the completed-visit review: enter Office B in the price calculator, copy it into the review, then replace actual hours with 5.25. The copied original estimate stays fixed while you edit the actuals. Download a CSV if you want a record; the page does not save it for you.
Decide what the overrun means
At the $200 price and $50 non-labor cost, six cleaner-hours are the break-even limit. Four hours are the allowance for the chosen 25% target. The 5.25-hour visit falls between those two limits.
- One-time condition: record the cause and keep it separate from normal maintenance assumptions.
- Added customer work: compare the actual task list with the agreed scope and use the agreed change process.
- Repeated task underestimate: update the future labor budget using comparable completed visits.
- Rushed or unfinished work: do not treat the shorter time as an efficiency gain until the agreed completion standard is met.
Record the service date, tasks completed, each cleaner’s time, supplies, paid travel, overhead allocation and any exception. Use the visit checklist beside the financial review. One unusual visit does not establish a reliable production rate.
Trace Office B back to a task plan
The four-hour Office B arithmetic uses the same $150 cost and $200 price as the complete Office A bidding example. The names describe teaching scenarios, not different market observations.
For an editable starting point, open the six-task office plan. It totals 240 cleaner-minutes including setup. Download its original inputs, then record any quantity or rate you change in the plan notes. When a completed visit uses 5.25 cleaner-hours, the total is 315 minutes: an extra 75 cleaner-minutes. Record which tasks or interruptions explain those minutes before updating the next estimate.
The financial review shows the cost effect; it does not determine the operational cause. Keep the task notes and the visit outcome together so that a missed task cannot be mistaken for a productivity improvement.
