- employees all-in-cost is ~$5000 per month paying $20-something an hour (they will be hitting OT as well, because they arrive before dropoff and stay after pickup). Typical maximum legal ratio might be 5 to 1 kids to carers depending on age. This means just for basic labor, every parent is paying $1000 a month.

- Next there is commercial rent. In a metro area, easily $5-$10k a month. Amortize that across 50 kids and that's another $200 a month.

- 2 meals + snacks daily. Adds in another $250 a month per kid assuming $11 per day per kid. More if you're prioritizing healthy fresh foods and not prepackaged garbage.

- Liability insurance which is very costly (insurers dont love cases involving dead or injured 3 year olds!)

- Utilities in a building that houses 50 people for 200+ hours a month.

- Throw in all the other costs. You have the admin costs of running a business like accounting and billing, and you've got to buy diapers, replace worn-out toys, and purchase endless crayons, and so on.

By the end of it all, you're looking at very slim margins working 55-hour weeks, your employees are paid barely more than a barista, and the parents are taking on a second mortgage with every kid.

Or about £1,500 per month.

Now, you can increase that to 8 kids per carer with older kids, but that's really stretching things if you want to run at all smoothly.
