"We wash so many orders a month but there's barely anything left" is a sentence you'll hear from most carpet cleaning operators. The problem usually isn't revenue — it's that the real cost per m² has never actually been calculated. In this article we break down every cost item, offer an on-page profitability calculator that gives instant results, and provide a downloadable Excel sheet so you can keep the same calculation on your own computer.
Cost items per m²: water, electricity, shampoo, fuel, labor, rent
The most accurate way to split carpet cleaning cost is into two buckets: variable costs (rising with every m² washed — water, electricity, shampoo/chemicals, and fuel if you offer pickup-and-delivery) and fixed costs (paid whether you wash a single carpet that month or not — rent, staff salaries, insurance, overhead).
Most businesses only calculate variable cost by thinking "a box of shampoo costs this much," but they forget the share of fixed costs once divided across the month's m² volume. In a low-volume month, the same rent and staff expense gets split across far fewer carpets — which significantly raises your real unit cost for that month. For how shampoo and chemical choice affects cost, see our shampoo comparison guide; if you do pickup-and-delivery, we cover the fuel line item in detail in our guide to cutting fuel costs.

This calculator is an estimation tool; your real profitability is reflected in monthly reports based on your cash and expense records.
Sample scenario: small and mid-sized business
The default values above (800 m²/month, 100/m² selling price, 15,000 rent, 20,000 staff cost) represent a mid-sized, single-location business and point to roughly a 28-30% net profit margin. A small, one-person business has lower rent and staff cost, but also lower volume — the result usually settles around a similar margin. Once you plug in your own numbers, you'll clearly see which cost item is squeezing you the most.
Download the Excel sheet
Just fill in your own numbers on the "Inputs" sheet in the Excel file; the "Results" cells update automatically using the same formulas as the calculator above. Entering the previous month's actual figures at the start of each month lets you track your profitability over time.
Break-even point: how many m² should you wash per month?
The break-even point is the minimum m² you need to wash to cover all of your fixed costs. The formula is simple: total fixed costs divided by the "contribution margin" (m² selling price minus variable cost per m²). Every month you fall short of this number, you lose money; every m² above it goes directly into net profit. The "Break-even point" row in the calculator computes this for you instantly.
5 levers to increase profitability
- Reduce idle capacity: since your fixed costs stay the same, washing more m² within the same month automatically lowers your unit cost.
- Optimize fuel/route costs: if you offer pickup-and-delivery, route planning directly affects fuel — the largest share of your variable cost. See cutting fuel costs.
- Control chemical dosage: over-dosing raises both cost and rinse time; see the shampoo comparison.
- Tighten credit/collection tracking: balances that look like profit on paper but never get collected lower your real cash profitability — see the credit tracking guide.
- Price according to cost, not competitors: instead of copying a competitor's price, price according to your own cost structure (see the section below).
Setting your price based on cost
Setting your price by only looking at nearby competitors' rates is risky — their cost structure may not match yours. First find your own total cost per m² using the calculator above, then add your target profit margin (typically 20-30%) to set your price.

Frequently Asked Questions
What is the cost per m² in carpet cleaning?
Variable costs like water, electricity and shampoo usually run between 10-20/m²; add the share of fixed costs divided by monthly volume and you get your real unit cost. The exact figure varies by business.
What profit margin should carpet cleaning have?
A healthy net profit margin in this industry is typically 15-30%; anything below that can signal high fixed costs or low volume.
What is the biggest cost item?
In most businesses, fixed costs like staff and rent make up the largest share; among variable costs, fuel and shampoo/chemicals stand out.
How is the break-even point calculated?
Your total fixed costs divided by the difference between your m² selling price and your variable cost per m²; this gives the minimum m² you need to wash to cover your costs that month.
