Bread in Finland is about 0.1 usd per slice Low quality cheese is about 8 usd / kg, assuming you need about 20g/portion that's 0.16 usd. Total is about 36c per portion.

If we assume power consumption of 5kw for the whole operation and power cost of 20c/kWh, that's 1usd/h

Assuming sales of 60 units per hour -one per minute, thats 60 usd of revenue per hour and 22.6 usd of non labor cost, it leaves 37.4e for labor, taxes, permits, tools, fuel.

It's at least only feasible in high volume locations.

I was with you until you suggested it would use 5kWh every hour. That's an insane amount of power even if they were using an electric griddle, which is unlikely. A small generator would be enough to power the lighting and refrigeration and then the griddle would run on gas, which is way cheaper than electricity (or the petrol for the electric generator).

I'd imagine energy costs would be a fraction of what you've calculated, and would scale up along with any increase in sales volume.

I make 37.4$ per hour? But what if I save on these 1$ per hour electricity costs
