How the math works.

Revenue = spots × average price per spot
Whatnot fees = ~8% platform + ~2.9% + $0.30 processing per spot. Default to 11% all-in.
Total cost = box cost + supplies + shipping + Whatnot fees + refund reserve
Net profit = revenue − total cost
Break-even price = total cost ÷ spots (the floor before you make a dollar)
