How much would it cost to run a field?

I've been thinking about how difficult it would be to run an airsoft field; So I decided to do some math to figure out what it would cost to operate one. Below is the data I've come with to get an idea of the costs of an airsoft field.

These numbers assume the field is an indoor field in New Jersey that is open for six hours per day every weekend and one extra day twice per month. It also assumes that the field only has walkons (no private parties) and does not rent any equipment or sell any merchandise or consumables.


First, some prices of various resources
Power: 13.58c / kwh

Water: $10.60 + ($5.95 / 1000 gallons)

NJ General Tax Rate: 0.03758 * property value / year

NJ Minimum wage: $8.25 / hr

General Liability Insurance: ~2000 / year

Airsoft Field Insurance: ~$2800 / year

Comcast business internet(starter package): $69.95/month; $840/year (what a ripoff)


Next, some assumptions about resource usage:
6 Hrs * 10 days = 60 Hrs / month open

Property value: $200000 

Power usage: 5062w / day
    50 100w light bulbs: 5000w
    1 computer: ~60w
    battery charges: 2w

Water usage: 4 gal * 10 uses = 40gal / day

Labor: Cashier + 3 refs = 24 man-hours / day

(Since the airsoft field is open ten days per month, I can multiply everything by 10 to get the total usage per month.)

Finally, adding up the costs per month
Power: 303.72kwh/month * 13.58c/kwh / 100 = $41.25

Water: $10.60 + ($5.95 * 0.4kgal / month) = $12.98 (is there such a thing as kilo-gallons? Now there is!)

Labor: 240 man-hours * $8.25 = $1980

General tax ($200000 * 0.03758) / 12 = ~$626

General Liability Insurance: $2000 / 12 = $167

Airsoft Field Insurance: $2800 / 12 = ~$234

41.25 + 12.98 + 1980 + 626 + 167 + 234 + 69.95(internet) = $3131.18 / month

3131.18 / 10 = ~$313.2 / day
313.2 / 25(sample admission price) = ~13 players per day

Based on the above calculations, an airsoft field needs at least 13 players per day it's open to break even.
Have you seen at least 13 other players at your local field the last time you played? If not, your local field may be struggling to pay their bills; Help them out by playing airsoft!

Have I made an error in my calculations? Are there any other expenses I forgot to mention? Let me know in the comments, and I'll update the cost.
