How to verify laundromat income
Laundromat listings often show a monthly income figure. Your job as a buyer is to test it against records the seller can't easily dress up. The water bill is a common starting point, but only if you understand its limits.

The water-bill-to-turns method
Washers use water every cycle, and the property's water bill is issued by a utility, not the seller. So buyers compare the water used in a period with the washer income claimed for the same period:
- Take the measured water volume for the period, from a meter that serves only the laundromat.
- Subtract water used for other purposes (restrooms, cleaning, any other tenant on the meter).
- Estimate gallons per cycle for each machine type.
- Estimate the mix of cycles across machine sizes, and how many were paid.
- Multiply paid cycles by the vend price for each machine type, and compare with the seller's claim for washers only.
A worked example (synthetic figures)
These are teaching figures, not recommended settings or a real store's results. Say the period used 10,000 gallons, with no deductions. Small machines use 10 gallons a cycle at a $2 vend price. Large machines use 20 gallons at $5. All cycles are assumed paid.
| Scenario | Cycles | Water | Washer receipts |
|---|---|---|---|
| A | 800 small, 100 large | 10,000 gal | $2,100 |
| B | 200 small, 400 large | 10,000 gal | $2,400 |
Same water, different mix, different income. Water alone cannot tell you which happened. That is why the method gives you questions, not a verdict.
Why a matching water bill is not proof
- Unpaid cycles (tests, free washes, service calls) still use water.
- Different machines use very different volumes per cycle.
- A shared meter can include another business or tenant's use.
- The bill's period may not match the income period.
- Whole-store sales (wash-and-fold, vending, dryers) do not belong in a washer-only comparison.
Records to ask the seller for
- Water and sewer bills for at least 12 months, showing measured volume, not just the amount due.
- Confirmation of what the water meter serves.
- Machine list: make, model, capacity and vend price for each washer, with any price changes and dates.
- Washer collection records or card-system reports by machine, for the same periods as the bills.
- Tax returns and bank deposits for the business.
- Repair and service records, which reveal machines out of service.
- The lease, including its remaining term and any water arrangements.
Red flags
- Only bill amounts, with no measured volumes.
- Income claims that cannot be split between washers and other revenue.
- Reluctance to give records for the same period as the claim.
- Deposits that don't line up with claimed collections.
- A water figure that only "works" with an unusual machine mix nobody can document.
A free option exists: Laundromat Resource advertises a free water-analysis spreadsheet through its free membership. A spreadsheet is a reasonable choice if you are comfortable building the scenarios yourself.
Frequently asked questions
Can a water bill prove laundromat income?
No. It is a cross-check. Unpaid cycles, machine mix, shared meters and mismatched periods all affect what the arithmetic can say.
What records should a laundromat seller provide?
Measured water volumes for 12 months or more, what the meter serves, a machine list with vend prices, collection or card reports, tax returns, bank deposits, repair records and the lease.
How do you calculate turns per day for a laundromat?
Turns are cycles per machine per day. Estimate total cycles from water used and gallons per cycle, then divide by machines and days. The result depends on your assumptions about machine mix.
What are red flags when buying a laundromat?
Bill amounts without volumes, income that cannot be split by source, records that do not match the claim period, and deposits that do not match claimed collections.
Does WashDeal verify a seller's income?
No. It calculates what your entered assumptions would produce and lists the evidence questions. A match is not an endorsement of the claim.
