Lemonade Stand Profit Calculator
Turn cups sold, price per cup, and costs into revenue, profit, and margin.
What it does
A lemonade stand is a first business in miniature: buy lemons, sugar, and cups once, then sell cup by cup until costs are covered and profit starts. The four numbers that matter are revenue, profit, margin, and break even cups.
The tool above takes cups sold, price per cup, and total costs. It returns revenue, profit, margin percent, and break even cups, so a Saturday of 120 cups at $1.50 with $45 costs reads as $180 revenue and $135 profit.
This math fits one product at one price with pooled costs. It does not fit multi size menus, free refills, or shared costs with a sibling stand selling cookies beside the lemonade.
Small business guides frame the same split: revenue minus costs gives profit, profit over revenue gives margin, and fixed costs over price gives break even units. Those three lines anchor any plan, from a stand to a shop.
Price with the weather in mind. Hot days lift cups but melt ice faster, so costs move with sales and the break even line should be rerun per outing.
How to use
- Count cups actually sold, not poured.
- Enter price per cup as posted on the sign.
- Enter total costs for lemons, sugar, cups, and ice.
- Read revenue first for the sales line.
- Read profit and margin for the keep line.
- Read break even cups for the next outing goal.
Formula
- cups
- Cups sold to paying customers.
- price
- Dollars charged per cup.
- costs
- All ingredient, cup, ice, and sign costs pooled.
Price must sit above zero. Zero cups gives zero revenue with negative profit equal to costs. Break even rounds up since partial cups do not sell.
Worked example
Example: 120 cups at $1.50 with $45 costs
Cups sold 120, price 1.50, total costs 45.
- Revenue: 120 x 1.50 = $180.00.
- Profit: 180 - 45 = $135.00.
- Margin: 135 / 180 x 100 = 75.00 %.
- Break even: 45 / 1.50 = 30 cups.
- Tool shows revenue $180.00, profit $135.00, margin 75.00 %, break even 30 cups.
Reference table
| Price | Revenue | Profit | Break even |
|---|---|---|---|
| $1.00 | $120.00 | $75.00 | 45 cups |
| $1.50 | $180.00 | $135.00 | 30 cups |
| $2.00 | $240.00 | $195.00 | 23 cups |
Limits
- One product, one price. Multi size menus need split lines.
- Pooled costs only. Shared cookie stand costs need dividing first.
- Ignores permits, table fees, and card processing cuts.
- Waste and free samples must sit inside costs or cups.
Common mistakes
- Counting poured cups instead of sold cups.
- Leaving ice and signs out of total costs.
- Figuring margin on costs instead of on revenue.
- Forgetting to round break even up to whole cups.
- Setting price below cost per cup at small volumes.

Questions
How is lemonade profit figured?
Cups times price gives revenue. Subtract total costs for profit.
What is margin on a stand?
Profit divided by revenue times 100. $135 on $180 is 75%.
How many cups break even?
Costs divided by price, rounded up. $45 at $1.50 needs 30 cups.
Should free samples count?
Yes in costs or as unsold cups. They lower profit either way.
What if I sell two sizes?
Run each size separately with its price and share of costs, then add profits.
Does weather change break even?
Only through costs and price. Ice use rises on hot days, so rerun costs per outing.
