Lemonade Stand Calculator

Work out how much your lemonade stand can profit using break-even (cost-volume-profit) analysis. Enter what you charge per cup, what each cup costs to make, your one-time setup costs, and how many cups you expect to sell.

Quick Facts

Formula
Profit = (Price x Cups) - (Fixed Costs + Cost per Cup x Cups)
Standard cost-volume-profit (break-even) analysis used for any single-product stand or small business.
Break-even
Cups = Fixed Costs / (Price - Cost per Cup)
The denominator is the contribution margin — what each cup adds toward covering fixed costs.

How the Lemonade Stand Calculator works

This tool applies standard cost-volume-profit (break-even) analysis — the same math used to price any small product-based business — to a lemonade stand. It separates your costs into two kinds: fixed costs you pay once regardless of how much you sell, and variable costs that scale with every cup you make. From those two categories, it derives revenue, total cost, profit, and the break-even point.

The formulas

With price per cup P, ingredient cost per cup C, fixed setup costs F, and cups sold Q:

Total Revenue = P x Q
Total Cost = F + (C x Q)
Profit = Total Revenue - Total Cost

The break-even point — how many cups you need to sell before you stop losing money — comes from dividing fixed costs by the contribution margin (the profit each cup contributes before fixed costs are covered):

Contribution Margin = P - C
Break-even Cups = F / (P - C)

Worked example

Say you charge $1.00 per cup, ingredients (lemons, sugar, water, ice, and cups) cost $0.35 per cup, your sign and table setup cost $20, and you expect to sell 100 cups. Revenue is $1.00 x 100 = $100. Total cost is $20 + ($0.35 x 100) = $55. Profit is $100 - $55 = $45. The contribution margin is $1.00 - $0.35 = $0.65 per cup, so the break-even point is $20 / $0.65 ≈ 31 cups — sell more than that and every additional cup adds $0.65 of pure profit.

Fixed costs versus variable costs

  • Fixed costs don't change with volume: a poster board and markers for the sign, a folding table, a pitcher you already own, or a permit fee. You pay these whether you sell 5 cups or 500.
  • Variable costs scale with each cup: lemons, sugar, water, ice, and disposable cups. Buying ingredients in bulk usually lowers the per-cup cost, which raises the contribution margin and lowers the break-even point.

What moves profit most

Because profit is revenue minus cost, three levers matter: the price you charge, the cost per cup, and the number of cups sold. Raising price by $0.10 adds $0.10 of pure profit on every cup sold (it flows straight through the contribution margin), while cutting the cost per cup by the same amount has an identical effect. Selling more cups only helps once you've cleared the break-even point — before that, extra cups just cover fixed costs faster.

Frequently Asked Questions

How is lemonade stand profit calculated?
Profit equals total revenue minus total cost. Total revenue is the selling price per cup times cups sold. Total cost is the one-time fixed costs (supplies like a pitcher, sign, or table) plus the variable cost per cup (lemons, sugar, cups, ice) times cups sold. In formula form: Profit = (Price x Cups Sold) - (Fixed Costs + Cost per Cup x Cups Sold).
What is the break-even point for a lemonade stand?
The break-even point is the number of cups you must sell so revenue exactly covers costs, leaving zero profit. It equals fixed costs divided by the contribution margin per cup (price per cup minus variable cost per cup): Break-even cups = Fixed Costs / (Price - Cost per Cup). Selling fewer cups than this means a loss; selling more means a profit.
What counts as a fixed cost versus a variable cost?
Fixed costs are one-time or flat expenses that do not change with how many cups you sell, such as a sign, a table rental, or a pitcher you already own. Variable costs scale directly with each cup sold, such as lemons, sugar, water, ice, and disposable cups. Separating the two is the foundation of break-even (cost-volume-profit) analysis.
How can I increase profit without selling more cups?
Since Profit = Revenue - Costs, you can raise profit by increasing the price per cup, lowering the ingredient cost per cup (buying supplies in bulk), or reducing fixed costs. Each dollar you shave off the variable cost per cup adds directly to the contribution margin, which also lowers the break-even number of cups.
