Laundromat Utility Costs Explained: Water, Sewer, Gas, Electric
Laundromat utility costs run a median 20% of gross revenue, and sewer is frequently the largest single line because many utilities bill it as a multiple of metered water. Only electricity has a usable state benchmark. Water, sewer, and gas must be modeled from the serving utility's actual rate schedule for the specific address.
Key takeaways
- Median 20% of gross revenue, mean 21%, and the most-cited operator problem at 53% (Source: CLA 2024 Laundry Industry Survey).
- Sewer is often the biggest line, billed as a multiple of metered water in many jurisdictions.
- Only electricity has a state benchmark: 12.94 cents/kWh U.S. all-sector average for 2024 (Source: EIA).
- Get 24-36 months of original bills, not a summary — and the utility's current rate schedule.
- A high ratio can mean overstated revenue, not just high costs.
The Four Components
| Component | Typical role | What drives it |
|---|---|---|
| Water | Large | Cycles run, machine capacity and type, extraction efficiency, leaks |
| Sewer | Often the largest | Frequently a multiple of metered water; local calculation rules |
| Gas | Large where dryers and water heating are gas | Dryer minutes sold, extraction efficiency, water heater efficiency, incoming water temperature |
| Electricity | Smaller unless dryers are electric | Motors, lighting, controls, HVAC; demand charges on commercial tariffs |
That ranking is not universal. A store with electric dryers in a high-rate state has a completely different profile from a gas-dryer store in a low-rate one, which is why every underwriting starts from the actual bills rather than from a template.
Water and Sewer: The Local Problem
There is no national dataset for water and sewer rates, because they are set by thousands of individual utilities — sometimes a city, sometimes a district, sometimes a private operator. Two stores ten miles apart can face materially different structures.
What to pull for a specific address:
- The serving utility's current commercial rate schedule
- The meter-size charge and the volumetric rate blocks
- Exactly how sewer is calculated, including any multiple of metered water
- Seasonal averaging rules, if any
- Surcharges, taxes, and any pass-through fees
- Backflow testing requirements and costs
- Connection or impact fees if you plan to add machines
- Whether the meter and service line belong to the landlord or the tenant
- Whether any other premises share the service
The sewer question is the one buyers most often skip and most often regret. A laundromat discharging heavily under a high sewer multiplier can find that line alone approaching or exceeding its water charge.
Gas
Gas typically serves the dryers and the water heating, and it is the second-largest line in most gas-equipped stores.
What drives it: dryer minutes sold, the extraction efficiency of the washers feeding them (wetter loads take longer to dry), water heater or boiler efficiency, incoming water temperature, and the local gas tariff.
Two diligence items specific to gas: confirm the total connected BTU load against the meter, regulator, and service line capacity — which constrains any future equipment change — and check exhaust runs and lint accumulation, because restricted airflow lengthens cycles and raises consumption.
Electricity
The one component with a usable public benchmark. The EIA's State Electricity Profiles report all-sector average retail prices by state, with a 12.94 cents/kWh U.S. figure for 2024 and wide state variation around it. The state pages on this site carry each state's number.
Two cautions. A statewide all-sector average is not a commercial tariff, and commercial tariffs carry demand charges that a per-kWh average does not capture. And the number only matters much if the dryers are electric — in a gas-dryer store, electricity covers motors, lighting, controls, and HVAC, which is a smaller line.
The Ratio Test
Compute total utilities over twelve months, from original bills, divided by gross revenue over the same aligned period.
| Result | Interpretation |
|---|---|
| At or below 20% | At or better than the surveyed median |
| 20-25% | Normal range; understand which component is heavy |
| Above 25% | A specific cause exists — find it before pricing the store |
The six causes of a high ratio, in the order to check them:
- A leak or running fixture — read the meter with everything off
- A water heater or boiler cycling continuously
- A softener regenerating excessively
- A top-loader-heavy machine mix, or low extraction speed lengthening dryer time
- An unfavorable local rate structure or sewer multiplier — permanent
- Revenue lower than represented — the denominator, not the numerator
That last one is the trap. A high ratio can mean costs are high, or it can mean the revenue figure is inflated. The check that separates them is comparing metered water consumption against manufacturer per-cycle usage for the actual installed machines. See water bill analysis.
What Efficiency Can and Cannot Do
ENERGY STAR reports that certified commercial washers are on average 9% more energy efficient and use about 45% less water than standard models. That is a real effect, applicable to qualifying models, and it should be modeled from your own cycle volume and your own tariffs rather than applied as a blanket percentage.
The order that produces results:
- Find leaks. Free, and frequently the whole answer.
- Fix the water heating. A system cycling continuously or poorly insulated is burning money every hour.
- Check the softener. Excessive regeneration is a quiet, ongoing cost.
- Then consider equipment. A capital decision, usually belonging to whoever will own the store for the next decade.
What This Means for a Purchase
On a $300,000-revenue store, moving utilities from 26% to 21% of revenue is $15,000 a year — roughly $52,000 of value at a 3.5x multiple. That is why the utility investigation is worth doing properly rather than accepting a seller's summary.
And whichever way it goes, the bills serve double duty: they answer a cost question and, through the consumption cross-check, a revenue question at the same time. Ask for them in your first document request.
Who Pays for What: The Lease Question
Utility cost is not only about rates. It is also about which party owns and maintains the infrastructure, and that is a lease question a generalist review frequently skips.
| Item | Why it matters in a laundromat |
|---|---|
| Water service line and meter | A laundromat is an extreme-demand user; replacement is expensive |
| Backflow preventer | Annual testing and eventual rebuild; municipal requirement |
| Floor drains and sewer lateral | The highest-consequence item; heavy discharge, and a failure closes the store |
| Gas service, meter, regulator, piping | Constrains any equipment change as well as costing money |
| Electrical service and panel | Same |
| Shared service with other premises | You may be paying for a neighbor's usage |
| Sub-metering arrangements | Whether you are billed on actual consumption or an allocation |
Language putting all repairs "within the demised premises" on the tenant can, depending on how the premises are defined, include the sewer lateral and the gas train. Ask the question explicitly and get the answer in writing before closing. See laundromat lease review.
Budgeting Utilities in Year One
New owners consistently underestimate the opening months, because several utility items are one-time and none of them appear in a trailing P&L:
- Deposits on every account — water, sewer, gas, electric — since the accounts are new in your name
- Final meter reads and prorations at closing
- Backflow certification if it has lapsed
- Any capacity or connection charge if you add machines
- A leak you inherit, which is why the meter test in week one matters
Budget for these separately from ongoing operating expenses, and keep them out of the working-capital calculation so they do not quietly consume it.
Summary
Water and sewer are local and usually the largest combined line, with sewer often billed as a multiple of metered water. Gas serves the dryers and water heating and constrains any future equipment change through connected BTU load. Only electricity has a state benchmark, and even that is not a commercial tariff. Pull 24-36 months of original bills and the utility's rate schedule, compute the ratio, and if it is above 25%, work the six causes in order — including the possibility that the revenue, not the cost, is the problem.
The Next Step If You Are Looking to Buy
Frequently Asked Questions
Which utility costs a laundromat the most?
Usually water and sewer combined, because many utilities bill sewer as a multiple of metered water and a laundromat is a high-volume water user. Gas for dryers and water heating is typically next, with electricity smaller unless the dryers are electric. The ranking depends entirely on local rates and the equipment installed.
What should utilities be as a share of revenue?
A median 20% and a mean 21% among 377 owner-operators reporting 2023 results to the Coin Laundry Association. Utilities were also the most-cited operator problem in that survey at 53% of respondents. A store above 25% has a specific cause worth finding before purchase.
Can I estimate utilities from state averages?
Only electricity, and only loosely. The EIA publishes state all-sector average retail electricity prices, with a 12.94 cents/kWh U.S. figure for 2024. Water and sewer are set by the local utility and vary enormously between neighboring towns, so no state figure substitutes for the actual rate schedule.
What is a sewer multiplier?
A billing method where sewer charges are calculated as a multiple of metered water consumption rather than measured separately. Because a laundromat uses far more water than a typical retail tenant, that method often makes sewer the single largest utility line — and it is set by the serving utility, not by the state.
How do I verify the utility numbers a seller gives me?
Ask for 24-36 months of original bills showing meter reads and consumption, not a summary. Then pull the utility's current commercial rate schedule for that address and confirm the billing method, blocks, and any surcharges yourself. Summaries can omit exactly the months that would tell you something.
