Cleaning Business Break-Even Calculator: How Many Jobs Do You Need?
Calculate how many cleaning jobs or billable hours are needed to cover fixed costs, variable costs, owner income and a practical operating buffer.
Key takeaways
- Break-even changes depending on whether owner income is treated as a required cost.
- Use contribution per job, not the full invoice value.
- GST collected for the ATO is not operating revenue.
- A busy calendar can still sit below break-even if jobs are underpriced.
Break-even is the point where completed work has covered the costs included in the calculation. It is not automatically a good month. It simply means the business has stopped going backwards. For a sole cleaner, the useful question is how many properly priced jobs are needed before the week begins paying the owner.
The basic break-even formula
Break-even jobs = required costs for the period ÷ average contribution per job
Contribution per job is:
Job revenue excluding GST minus the variable costs caused by that job
Variable costs may include products, card fees, parking, outsourced labour and job-specific equipment hire.
Fixed costs include expenses that continue even when no job is completed, such as insurance, software, phone costs, registrations and a base level of vehicle cost.
Business break-even and owner break-even are different
A calculation that only includes business bills can make the result look reassuringly low. It may show that six jobs cover software, insurance and the phone bill while saying nothing about the owner's rent, food or income target.
Use two views:
- Operating break-even: fixed business costs only.
- Sustainable break-even: business costs plus the owner income and buffer the business is expected to produce.
Both are useful. They answer different questions.
Worked example
A cleaner has A$900 in monthly fixed business costs. Their average job produces A$180 in revenue excluding GST and carries A$35 in variable costs.
Average contribution per job is A$145.
Operating break-even: A$900 ÷ A$145 = 6.21 jobs per month
That means seven average jobs cover the listed business overhead. It does not pay the owner.
If the business must also produce A$5,000 a month for owner income and a A$300 buffer, the required amount becomes A$6,200.
Sustainable break-even: A$6,200 ÷ A$145 = 42.76 jobs per month
That is about 10 jobs a week in a four-week month.
The difference is the whole point of doing the calculation properly.
Use an average that represents the real calendar
Do not use one large bond clean as the average if most work is two-hour residential visits. Calculate the weighted average across a normal month.
A simple method is:
Total revenue excluding GST minus total variable job costs, divided by completed jobs
If service types are very different, calculate break-even separately for recurring residential, end of lease and commercial work. A single average can hide a weak service line.
What break-even can reveal
- The minimum number of jobs needed before taking a week off
- Whether a new software or vehicle cost is affordable
- How much a price rise changes required volume
- Whether a discount campaign needs too many extra jobs to pay for itself
- Whether hiring increases capacity enough to cover employment costs
Break-even does not tell you whether the work is physically sustainable or whether customers will accept the price. It gives you the financial line those decisions must clear.
The bottom line
Break-even changes depending on whether owner income is treated as a required cost. Use contribution per job, not the full invoice value. GST collected for the ATO is not operating revenue. A busy calendar can still sit below break-even if jobs are underpriced.
Frequently asked questions
Short answers to common questions about this topic.
Keep personal income tax separate from the operating calculation. If the owner-income target is before tax, make that clear. GST should be excluded from revenue because it is collected for the ATO.

A cleaning business's advertised hourly rate is not its profit margin. Once travel, products, insurance, admin time, payment processing fees and tax obligations are accounted for, the real margin is usually meaningfully lower than the headline number suggests, which is exactly why understanding the full cost picture matters more than picking a "market rate" in isolation.
