Break-Even Analysis: How Many Sales Do You Need to Cover Your Costs?
Break-even analysis tells you how many units you must sell—or how much revenue you need—to cover all your costs. At the break-even point, your profit is exactly zero.
Break-even units = Fixed Costs ÷ Contribution Margin per Unit
For example, if monthly fixed costs are ₹60,000 and each sale contributes ₹300 toward those costs, you need 200 sales per month to break even.

What Is Break-Even Analysis?
Break-even analysis answers a practical business question: “How much do I need to sell before I stop losing money?”
The calculation depends on three things:
- Fixed costs: costs that generally remain the same regardless of sales, such as rent, certain salaries, software and insurance.
- Variable costs: costs that rise with each sale, such as ingredients, packaging, shipping or product costs.
- Selling price: the amount you receive for each unit or sale.
What Is Contribution Margin?
Contribution margin is what remains from a sale after its variable cost has been paid.
Contribution Margin = Selling Price - Variable Cost
Suppose an Indian café sells an order for ₹500 and the variable cost is ₹200:
₹500 - ₹200 = ₹300 contribution margin
The ₹300 is not profit yet. It first helps pay the café's fixed costs. After those costs are covered, further contribution can become profit.
Contribution Margin Ratio
For break-even revenue, use the contribution margin ratio:
Contribution Margin Ratio = Contribution Margin ÷ Selling Price × 100
In the example, ₹300 ÷ ₹500 = 60%.
How to Calculate Break-Even Sales in Units
The formula is:
Break-Even Units = Fixed Costs ÷ Contribution Margin per Unit
Imagine the café has:
- Fixed costs: ₹60,000 per month
- Average selling price: ₹500
- Variable cost per order: ₹200
Contribution margin = ₹500 - ₹200 = ₹300.
₹60,000 ÷ ₹300 = 200 orders
The café therefore needs 200 orders per month to break even—about 7 orders a day over a 30-day month.
How to Calculate Break-Even Revenue
If your business sells several products, calculating units may not be practical. You can calculate the sales revenue required instead:
Break-Even Revenue = Fixed Costs ÷ Contribution Margin Ratio
Using the same café:
₹60,000 ÷ 0.60 = ₹1,00,000
So the café needs ₹1,00,000 in monthly sales to cover its costs, assuming its contribution margin remains 60%.
How Many Sales Do You Need for a Profit Target?
Break-even only gets you to zero profit. To calculate the sales needed for a target profit:
Required Units = (Fixed Costs + Target Profit) ÷ Contribution Margin per Unit
For a ₹30,000 target profit:
(₹60,000 + ₹30,000) ÷ ₹300 = 300 orders
The café needs 300 orders per month to cover its costs and earn ₹30,000, assuming the same price and variable cost.
Why Break-Even Matters Before Starting a Business
A business can have sales and still lose money. Break-even analysis shows the sales volume required to make your cost structure work.
Before committing to rent, staff, equipment or inventory, check whether your expected customer or order volume can realistically reach your break-even point. Also test what happens if prices fall, variable costs rise, or fixed costs increase.

Frequently Asked Questions
What is the break-even point?
The break-even point is where total revenue equals total costs, so the business makes neither a profit nor a loss.
What is the break-even formula?
Break-even units = Fixed Costs ÷ Contribution Margin per Unit. Break-even revenue = Fixed Costs ÷ Contribution Margin Ratio.
Is break-even the same as profit?
No. Break-even means your costs are covered and profit is zero. Sales above break-even can generate profit if costs and margins remain unchanged.
Can break-even analysis be used for multiple products?
Yes. You can estimate break-even revenue using a blended contribution margin based on your expected sales mix.
