What does this calculator do?
The Lemonade Stand Calculator turns your ingredient costs (lemons, sugar, cups, ice), your sale price per cup, and how many cups you sell into a full picture of the business: cost per cup, profit per cup, how many cups you need to sell just to break even, and your daily, weekly, and monthly profit. It's built for a kids' lemonade stand, a school fundraiser, or any small cash-only stand — but the math works for any batch-and-cup business.
How the numbers are worked out:
- Total batch cost:
lemons + sugar + cups + ice. - Cost per cup:
totalBatchCost ÷ cupsPerBatch. - Profit per cup:
salePricePerCup − costPerCup; profit margin is that as a percentage of the sale price. - Break-even cups:
ceil(totalBatchCost ÷ salePricePerCup)— how many cups from one batch you need to sell to cover that batch's cost. - Batches needed per day:
ceil(cupsSoldPerDay ÷ cupsPerBatch). - Daily profit:
(cupsSoldPerDay × salePricePerCup) − (batchesNeeded × totalBatchCost); weekly is× 7, monthly is× 30.
Worked example: $5 lemons + $2 sugar + $3 cups + $1.50 ice = an $11.50 batch that makes 20 cups, so each cup costs $0.58. Selling at $1.50/cup gives $0.93 profit per cup (a 61.7% margin), and you break even after 8 cups. Selling 50 cups a day needs 3 batches and nets about $40.50/day.
How to use it
- Enter what one batch of lemonade costs you: lemons, sugar, cups, and ice.
- Enter how many cups per batch that makes.
- Enter your sale price per cup.
- Enter roughly how many cups you sell per day.
The tables and the profitable/not-profitable verdict update as you type. You can copy or download any table as CSV.
What if I sell more cups than one batch makes?
The calculator rounds up to the number of full batches needed (batches needed = ceil(cups sold ÷ cups per batch)), then costs all of them — so if you make 20-cup batches but sell 50 cups, it correctly costs 3 batches (60 cups' worth of ingredients), not 2.5.
Why is my margin different from real life?
This models pure ingredient cost against your sale price — it doesn't account for a table, sign, ice chest, or your own time, and it assumes every cup you make gets sold (no spoiled batches or leftover lemonade). Treat it as your ingredient-only profit ceiling.
