How the lemonade stand calculator works
This calculator applies simple, real business math — revenue minus costs equals profit — to a classic first business project.
The formula
Profit = (Cups Sold × Price per Cup) − (Cups Sold × Ingredient Cost per Cup) − Fixed Costs. Fixed costs are one-time expenses like a sign or table that don’t change no matter how many cups are sold.
It’s a friendly way to introduce basic profit-and-loss thinking for a small, real or hypothetical venture.
