Most owners of a launderette know roughly how busy they are. Far fewer know whether they are actually making money on each wash, 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 launderette, 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 launderette 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 launderette
1. Washes sold
How to calculate it: Washes and dries in the month
Your volume.
2. Average price per wash
How to calculate it: Revenue ÷ washes
Rises with service washes.
3. Utility cost % of sales
How to calculate it: Energy and water ÷ revenue
The biggest pressure on margin.
4. Gross margin
How to calculate it: (Revenue − utilities and staff) ÷ revenue
What is left for rent and overheads.
5. Machine downtime
How to calculate it: Hours machines are out of order
Broken machines lose sales.
6. Service wash share
How to calculate it: Service wash revenue ÷ total revenue
Higher-margin work.
7. Commercial contract revenue
How to calculate it: Revenue from business accounts
Steady, predictable income.
Interpreting these measures in practice
Pair washes sold and average price with utility cost per cycle and machine uptime. A rise in sales can be outweighed by energy use, a faulty machine or frequent short cycles, so compare bills and meter readings over similar periods. Separate self-service from service-wash revenue and include staff time and detergent for the latter. Track machine-level downtime and repair cost to decide whether preventative maintenance or replacement is more economical. Check the mix of machine sizes as well: a busy smaller washer and an underused large machine have different revenue and utility patterns, so a site-wide average can hide where prices or maintenance need attention.
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 launderette takes £7,000 in a month and spends £3,900 on the direct costs of delivering the work. Gross profit is £3,100, a gross margin of 44%. 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
- Service washes and ironing at higher margins
- Commercial contracts with cafés, salons and holiday lets
- Repricing when energy costs rise
- Keeping machines running with planned maintenance
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 launderette owner earns in the UK.
How to review your KPIs every month
1. Update your records for the month: washes, 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.
Run the numbers on your own business

It costs £15 once, with no subscription. Before you open, work out your start-up costs with our free laundromat start-up calculator.
Frequently asked questions
What is the most important KPI for a launderette? Gross margin, because it shows whether your prices cover the direct cost of each wash. If it is wrong, growth only makes things worse.
Which KPIs should a new launderette track first? Start with washes sold, average price per wash and utility cost % of sales. 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 wash is below target, your prices are too low for your costs, however busy you are.
What is a good gross margin for a launderette? 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.
