How many washer turns per day does a laundromat need?
Start with one paid washer start as the sales unit. Build the realized revenue per turn from the washer-size mix, attached drying, discounts and refunds, then divide the monthly cost requirement by contribution per turn and operating days. Compare the result with both installed capacity and observed paid demand.
What you will produce: A washer-turn break-even calculation, a machine-size observation log and a downside decision.

What to have ready
Bring the washer count by size, posted washer prices, dryer pricing, payment reports or observations, operating days, cycle-level variable costs, the complete paid roster, occupancy, other fixed costs, depreciation and maintenance investment.
Work through the calculation and decision
How should you define one paid turn?
Count one paid washer start as one turn. Record the machine size and net washer charge. Treat the drying that follows as attached revenue in the realized basket, not as another washer turn. Keep vending, wash-and-fold and pickup or delivery outside the unit unless the operating model explicitly includes them.
Calculate realized revenue per turn from the actual mix: washer revenue plus attached dryer revenue and other included sales, less discounts and refunds, divided by paid washer starts. A posted large-machine price is not the average realized basket when customers use several sizes.
How do monthly costs become daily break-even turns?
Contribution per turn equals realized revenue per turn multiplied by one minus the variable-cost share. Include water, sewer, gas, electricity, payment fees and truly volume-driven supplies once. Keep scheduled payroll, rent and standing overhead in monthly fixed costs.
For EBIT break-even, add monthly depreciation to fixed costs, divide by contribution per turn and then divide by operating days. For operating cash break-even, use the same boundary but replace depreciation with actual maintenance investment and other recurring asset cash. Label which threshold you are using.
How do you test whether the threshold is usable?
Calculate installed washer capacity from machine count and available cycles, then reduce it for expected downtime and an uneven mix. Capacity is only a ceiling. Observe comparable stores by machine size and time window to test whether paid demand can approach the threshold.
Run a downside case with fewer paid turns and a lower realized basket, while keeping committed payroll and occupancy unchanged. If break-even depends on every washer turning at the same strong rate, revise the site, machine mix, price or fixed commitments before ordering equipment.
A 36-washer reference needs about 130 paid turns per day for EBIT break-even
This authored example uses the site reference scenario and does not represent an industry average or a local forecast.
| Input or result | Calculation | Reference |
|---|---|---|
| Realized revenue per paid washer turn | Authored washer-size and dryer mix | $9.00 |
| Variable cost share | Utilities, payment fees and variable supplies | 24% |
| Contribution per turn | $9.00 × 76% | $6.84 |
| Monthly fixed operating costs | Paid payroll, rent and other standing costs | $19,936 |
| Monthly depreciation | Selected installed assets ÷ 60 months | $6,750 |
| EBIT break-even turns | ($19,936 + $6,750) ÷ $6.84 | 3,902 turns/month |
| Daily EBIT break-even | 3,902 ÷ 30 | 130.1 turns/day |
| Reference paid-turn assumption | 145 × 30 | 4,350 turns/month |
What this changes: The reference clears EBIT break-even by only about 15 paid turns per day. At 116 turns per day, 20% below the assumed volume, mature monthly EBIT becomes negative while the lease and paid roster remain.

Choose your next action
| If your finding is… | Your next action |
|---|---|
| Observed paid turns remain below the threshold | Reduce committed cost or change the offer and retest before treating capacity as demand. |
| Dryer queues or machine-size queues bind first | Revise the equipment mix and recalculate installed cost and throughput. |
| The result depends on a high realized basket | Verify the actual washer-size and drying mix instead of applying the largest posted price. |
Errors that can change the result
- Counting a washer start and its drying as two washer turns.
- Using installed machine doors as observed demand.
- Dividing total startup cash by one mature month and calling the result payback.
