March utility cost per cycle, prepared for Ines Conway

Bills

Electric: $1,184.60
Gas: $1,926.40
Water and sewer: $2,310.75
Grand total: $5,421.75

How each bill was split

Water and sewer: $2,310.75 to washers (all washers, per Ines)
Gas: $674.24 to washers (35%, water heater) and $1,252.16 to dryers (65%)
Electric (Ines's estimate): $355.38 to washers (30%), $473.84 to dryers (40%), $355.38 to the building (30%)

Totals by group

Washers: $2,310.75 + $674.24 + $355.38 = $3,340.37
Dryers: $1,252.16 + $473.84 = $1,726.00
Building: $355.38
Check: $3,340.37 + $1,726.00 + $355.38 = $5,421.75, which matches the grand total

Cost per cycle

Washer units: 1,150 cycles of 20 lb at 1 unit each, plus 620 cycles of 40 lb at 2 units each, gives 1,150 + 1,240 = 2,390 units
Washer cost per unit: $3,340.37 divided by 2,390 = about $1.40
Dryers: $1,726.00 divided by 2,600 cycles = about $0.66 per cycle
Building cost: $355.38 divided by 4,370 total cycles (1,150 + 620 + 2,600) = about $0.08 per cycle

| Cycle | Direct cost | Building share | Utility cost per cycle |
|---|---|---|---|
| 20 lb wash | $1.40 | $0.08 | $1.48 |
| 40 lb wash | $2.80 | $0.08 | $2.88 |
| Dry | $0.66 | $0.08 | $0.75 |

The last column is added before rounding, so a row can differ by a cent from the two rounded columns beside it (for example, dry is $0.664 plus $0.081, which is $0.745 before rounding).

Utility cost compared to price

20 lb wash at $3.75: utilities are about 39% of the price
40 lb wash at $6.50: about 44%
Dry at $2.00: about 37%
One 20 lb wash plus one dry: about $2.22 in utilities (added before rounding, so it differs by a cent from the rounded table figures) against $5.75 paid, about 39%

These figures cover utilities only. They do not include rent, labor, soap, repairs, or equipment payments.

Questions for the owner

Is the electric split (30% washers, 40% dryers, 30% building) from a meter or technician, or your own estimate? We labeled it as your estimate. If you want exact figures, a licensed electrician can tell you about submeters.
Do you have February's bills and counts? We can compare months once you share them.
Did any bill include late fees or other charges that should be taken out?

What it does

Takes a month of utility bills and the number of cycles run, then works out what the utilities cost for one wash cycle (by machine size) and one dry cycle. It also shows how much of each cycle's price goes to utilities.

Use it when: Use when a laundromat owner wants to break a monthly utility bill (water, sewer, gas, electric) down into the cost of one wash cycle and one dry cycle, such as "what does a wash cost me," "break down my utilities per load," or "am I making money on the dryers."
