A laundromat sells time on machines. Customers pay to use a washer for 25 to 35 minutes and a dryer for 30 to 45 minutes. There is little inventory, no receivables and, in a self-service model, small payroll. That is why the business attracts investors. But the store still carries heavy fixed costs: rent, water and sewer, natural gas, electricity, equipment loans and repairs.
Every store is different, but a self-service laundromat's costs, as a share of revenue, often fall in these ranges:
| Cost category | Typical share of revenue |
|---|---|
| Rent, CAM charges, property tax share | 15%–30% |
| Water and sewer | 8%–15% |
| Natural gas (water heating and dryers) | 5%–12% |
| Electricity | 4%–8% |
| Labor (attendants, if any) | 0%–25% |
| Repairs and parts | 3%–6% |
| Insurance | 1%–3% |
| Card processing and payment system fees | 1%–4% |
| Cleaning supplies, trash, pest control | 1%–3% |
| Marketing and software | 1%–3% |
| Net operating income before debt service | 20%–35% |
The wide labor range is the key variable. An unattended store with remote monitoring may spend almost nothing on staff. A fully attended store open 6 a.m. to 10 p.m. with wash-and-fold will spend a quarter of revenue on wages, though it also earns more.
Laundromat buyers usually talk about net operating income (NOI) or seller's discretionary earnings (SDE). NOI is revenue minus operating costs, before loan payments and owner pay. SDE adds back the owner's salary and personal perks. Know which one a broker is quoting.
The core productivity measure is turns per day: the average number of paid cycles each washer completes daily. A store's washers might average anywhere from 3 to 8 turns per day, with busy urban stores higher and struggling stores lower. Dryer revenue follows washer revenue, so most owners analyze the washer side first.
Monthly washer revenue = Number of washers × Average vend price × Turns per day × 30
Example: 30 washers × $5.25 average vend × 5 turns × 30 days = $23,625 in monthly washer revenue. If dryer revenue adds roughly 25% to 40% on top, the store might take in about $29,500 to $33,000 a month from self-service alone.
The same formula tells you what improvement is worth. Raising turns from 5 to 6 on 30 washers at $5.25 adds $4,725 a month. Raising the average vend by $0.50 at 5 turns adds $2,250. Both are realistic levers.
Here is an illustrative month for a 2,800-square-foot store with 34 washers and 40 dryer pockets, partly attended, with a small wash-and-fold service.
| Line | Amount | % of revenue |
|---|---|---|
| Washer revenue | $24,500 | 57% |
| Dryer revenue | $8,600 | 20% |
| Wash-and-fold and pickup/delivery | $8,200 | 19% |
| Vending (soap, snacks) | $1,700 | 4% |
| Total revenue | $43,000 | 100% |
| Rent and CAM | $8,400 | 19.5% |
| Water and sewer | $4,700 | 10.9% |
| Natural gas | $3,100 | 7.2% |
| Electricity | $2,300 | 5.3% |
| Attendant and wash-and-fold labor with payroll taxes | $7,900 | 18.4% |
| Repairs and parts | $1,500 | 3.5% |
| Insurance | $650 | 1.5% |
| Payment system and card fees | $900 | 2.1% |
| Supplies (detergent for W&F, bags, cleaning) | $900 | 2.1% |
| Trash, pest control, alarm, internet | $450 | 1.0% |
| Marketing and software | $500 | 1.2% |
| Net operating income | $11,700 | 27.2% |
| Equipment and acquisition loan payments | $6,200 | 14.4% |
| Cash flow to owner before income tax | $5,500 | 12.8% |
Notice two things. First, the debt service line is large; a laundromat is often bought with substantial borrowing. Second, wash-and-fold brings revenue but also most of the labor cost. That is fine if it is priced correctly, which Chapter 9 covers.
Laundromats tend to have long lives because demand is steady: renters without in-unit machines need clean clothes every week regardless of the economy. Stores that fail usually share a few causes:

How to buy a laundromat without overpaying: valuation multiples, testing revenue with water bills, inspecting equipment, the lease and structuring the deal.
Usually as a multiple of net operating income or seller's discretionary earnings, often discussed in a range of roughly 3 to 6 times annual net, adjusted for lease length, equipment age, location and trends. Verify current multiples with local brokers.
Compare tax returns, bank deposits and card or app payment reports, and estimate washer cycles from 12 to 24 months of water bills divided by gallons used per cycle. All the evidence should point to similar numbers.
Total remaining term including renewal options, ideally at least as long as your loan, plus an assignment clause, an exclusive-use clause, and no demolition or relocation clause. Get a signed estoppel certificate from the landlord.
