Most owners of a cleaning business know roughly how busy they are. Far fewer know whether they are actually making money on each clean, where profit is leaking, or which part of the business is growing. Key performance indicators, or KPIs, answer those questions in a few numbers you can check every month.
This guide covers the 7 KPIs that matter most for a cleaning business, how to calculate each one, and what to do when a number moves the wrong way.
Why KPIs matter more than turnover
Turnover tells you how much came in. It does not tell you whether prices cover costs, whether time is being used well, or whether cash will be there next month. A cleaning business can grow turnover and still make less profit if costs grow faster. KPIs show you the drivers behind the result, early enough to act.
The 7 KPIs for a cleaning business
1. Average job value
How to calculate it: Revenue ÷ cleans
Rises with add-ons and larger properties.
2. Hours worked
How to calculate it: Cleaning hours delivered
Your capacity.
3. Revenue per hour
How to calculate it: Revenue ÷ hours
Whether prices cover cleaners and travel.
4. Supplies % of revenue
How to calculate it: Products and equipment ÷ revenue
Catches waste and underpriced deep cleans.
5. Labour cost % of revenue
How to calculate it: Cleaner wages ÷ revenue
The core margin check.
6. Client retention
How to calculate it: Clients kept ÷ clients at start of period
Regular clients are recurring income.
7. Complaints
How to calculate it: Complaints ÷ cleans
A quality measure.
Interpreting these measures in practice
Compare revenue per cleaning hour with paid hours, travel, supplies and supervision, and split recurring contracts from one-off or deep-clean work. Retention and complaints should be read together with re-cleans: a low complaint count is not useful if clients quietly leave. Track missed visits and cover costs when staff are absent. If labour percentage worsens, first identify whether the cause is underpricing, travel, scope creep or low utilisation before changing wages or service standards.
Start with the profit basics
Alongside the industry KPIs above, every owner should check four headline figures each month:
- Total income for the month and year to date
- Total costs, split into direct costs and overheads
- Net profit and operating margin
- Lowest cash balance in the next 12 weeks, from a cash flow forecast
If net profit is falling while turnover rises, look at the cost KPIs first. If cash is tight while profit looks fine, look at unpaid invoices.
An example month (illustrative figures)
Say a cleaning business takes £9,000 in a month and spends £6,100 on the direct costs of delivering the work. Gross profit is £2,900, a gross margin of 32%. If last month the margin was several points higher on similar turnover, something has changed in prices, costs or the mix of work, and the KPIs above show where to look. These figures are illustrations only: use your own.
What to do when the numbers slip
- Regular weekly or fortnightly contracts
- Tight areas so cleaners spend less time travelling
- Add-ons such as ovens, carpets and end of tenancy cleans
- Reviewing prices each year
Pick one action at a time, so you can see what made the difference. If you are asking what the business could pay you, read how much a cleaner earns in the UK.
How to review your KPIs every month
1. Update your records for the month: cleans, sales, costs and invoices. 2. Compare each KPI with last month and the same month last year, so seasonal swings do not mislead you. 3. Pick the one number that moved most in the wrong direction and find out why. 4. Decide one action for next month, such as a price change, a rota change or chasing a debtor. 5. Check the result at the next review.
Fifteen minutes a month on this routine is enough to catch most problems while they are still small.
Common mistakes with KPIs
Tracking too many numbers. Pick the handful that drive your profit and review them consistently.
Looking at one month in isolation. Trends matter more than single results.
Not acting on what you find. A KPI that never changes a decision is just a number.
Keeping figures in your head. Write them down, or let a spreadsheet calculate them, so nothing is guessed.

Frequently asked questions
What is the most important KPI for a cleaning business? Gross margin, because it shows whether your prices cover the direct cost of each clean. If it is wrong, growth only makes things worse.
Which KPIs should a new cleaning business track first? Start with average job value, hours worked and revenue per hour. They are quick to work out and show straight away whether your pricing and capacity are right.
Can KPIs help me set prices? Yes. If your margin or rate per clean is below target, your prices are too low for your costs, however busy you are.
What is a good gross margin for a cleaning business? There is no single benchmark, because margins depend on your mix of work, location and whether you pay staff. The useful test is your own trend: a margin that holds steady or rises as you grow is healthy, and a falling one needs action on price or costs.
How often should I check my KPIs? Monthly for most figures, and weekly for cash and unpaid invoices.
Do I need software to track KPIs? No. A spreadsheet that calculates the figures from your records works well for most small businesses and avoids monthly fees.
