Break-even Point
How many units do you need to sell to stop losing money? Fixed vs variable costs, contribution margin, margin of safety, operating leverage.
The break-even question
“How many units do I need to sell to stop losing money?” Every entrepreneur asks this. The break-even point is the answer — the volume at which total revenue exactly equals total cost, leaving zero profit and zero loss. Below it you lose money. Above it, every additional unit drops contribution straight into profit. Understanding break-even shapes pricing, capacity, and go/no-go decisions on new products.
Fixed vs. variable costs
- Fixed costs stay constant regardless of volume — at least within a relevant range. Rent, executive salaries, insurance, depreciation on existing equipment.
- Variable costs rise and fall with volume. Raw materials, direct labour (in hourly setups), sales commissions, packaging.
- Mixed costs have both elements — e.g., a utility bill with a fixed connection charge plus a per-unit usage rate.
The split isn’t always obvious. Manager salary is fixed below 500 units/day, but you need a second manager above that. Cost behaviour is linear only within a relevant range.
The break-even formulas
Or directly in ₹:
Where contribution margin % = Contribution per unit ÷ Selling price.
Worked example
A café sells coffee at ₹200 per cup. Variable cost per cup (beans, milk, cup, sugar): ₹60. Fixed monthly costs (rent, salary, utilities, insurance): ₹1,40,000.
- Contribution per cup = 200 − 60 = ₹140
- Contribution margin % = 140 ÷ 200 = 70%
- Break-even cups = 1,40,000 ÷ 140 = 1,000 cups/month
- Break-even revenue = 1,000 × 200 = ₹2,00,000/month
If the café averages 50 cups a day across 30 days = 1,500 cups, it’s above break-even. Each cup beyond 1,000 contributes ₹140 to profit. The 500 surplus cups → ₹70,000 profit for the month.
Target profit analysis
Want to earn ₹50,000 profit? Add it to the fixed cost in the numerator:
Café needs to earn ₹50,000 profit: (1,40,000 + 50,000) ÷ 140 = 1,357 cups.
Margin of safety
How far above break-even are you? The margin of safety measures the buffer.
Often expressed as a percentage: a 33% margin of safety means sales can drop 33% before reaching break-even. Higher = lower risk.
Operating leverage
A business with high fixed costs and low variable costs has high operating leverage — small revenue swings produce big profit swings. SaaS companies (low variable cost) have extreme operating leverage; their break-even comes late but every extra customer is mostly profit. Restaurants (high variable cost) have low operating leverage; profits move proportionally with revenue.
Multiple products — weighted break-even
Real businesses sell more than one product, each with its own contribution. The formula uses a weighted-average contribution based on the sales mix.
Example: 60% of revenue comes from Product A (₹100 contribution per ₹1,000 revenue = 10% CM) and 40% from Product B (₹400 contribution per ₹1,000 = 40% CM). Weighted average CM = (60% × 10%) + (40% × 40%) = 22%. Break-even revenue = Fixed cost ÷ 22%.
Lesson recap
- Break-even point = where revenue equals total cost.
- BE units = Fixed cost ÷ Contribution per unit.
- Margin of safety = how far above BE you are; buffer against downturns.
- High operating leverage = high fixed cost % = big swings; low = stable.
- Multi-product BE uses weighted-average contribution by sales mix.

Worked Example — Cafe Mocha Break-Even
Suppose Cafe Mocha, Pune, sells coffee at ₹150 a cup. Variable cost per cup (beans, milk, cup, barista wage proportion) = ₹60. Contribution per cup = ₹90. Monthly fixed costs (rent ₹1,20,000 + manager salary ₹40,000 + utilities ₹20,000 + other ₹20,000) = ₹2,00,000. BEP in units = ₹2,00,000 / ₹90 = 2,223 cups/month, or about 74 cups a day. BEP in rupees = 2,223 × ₹150 = ₹3,33,450. If the actual sales are 100 cups a day = 3,000 cups/month = ₹4,50,000, then Margin of Safety = ₹4,50,000 − ₹3,33,450 = ₹1,16,550 (26% of sales). The profit = 3,000 × ₹90 − ₹2,00,000 = ₹70,000 monthly.
Common Break-Even Mistakes
- Assuming linearity beyond capacity (step costs kick in)
- Forgetting to include all fixed costs (interest, depreciation, salaries)
- Mixing variable and fixed cost classification
- Computing BEP without testing assumptions in sensitivity
Frequently Asked Questions
Why is BEP useful even for an established business?
It anchors pricing, helps assess special order pricing, evaluates whether a marketing spend will pay back, and guides cost-cutting decisions.
What is the contribution margin ratio?
Contribution per unit ÷ Selling Price per unit. It is the proportion of each rupee of sales available to cover fixed costs and contribute to profit.
How does BEP help start-ups?
By identifying the minimum monthly traction needed to avoid burn — which directly influences fundraising requirements, runway and unit-economics decisions.
CVP Analysis Beyond Single-Product
Multi-product CVP analysis computes weighted average contribution margin based on sales mix. Composite BEP = Total Fixed Costs / Weighted Average Contribution per Unit. Indian QSRs (McDonald’s, KFC, Pizza Hut) and FMCG firms with multiple SKUs use this approach to set product-level pricing while monitoring overall break-even. The sales mix can shift seasonally — sweet products do well during festival months in India — and BEP recomputation should be a monthly exercise. A bakery sells cakes (price ₹500, VC ₹200, mix 30%) and biscuits (price ₹100, VC ₹40, mix 70%). Weighted contribution = (0.30 × ₹300) + (0.70 × ₹60) = ₹132 per composite unit. If fixed costs are ₹66,000/month, BEP = 500 composite units. Mix-shift towards higher-margin cakes (say 50:50) raises weighted contribution to ₹180, lowering BEP to 367 units — a 27% improvement.
Strategic Use of BEP
Indian unicorn startups (Zomato, Swiggy, Paytm, PB Fintech) report unit-level BEP as a key investor metric during fundraising. The shift from “growth at all costs” to “path to profitability” since 2022 has elevated BEP analysis from operational tool to strategic narrative. Master it; it will appear in every business school case, every CA/CMA exam, every corporate finance interview, and every investor pitch.
Multi-Period BEP Analysis
Single-period BEP is the introductory concept. Advanced analysis: rolling 12-month BEP, scenario-based BEP (best/base/worst case), and BEP with capital recovery (including depreciation and target ROCE). For a new business: Year 1 BEP often unattainable; track “months to break-even” instead. For a mature business: track “BEP utilisation %” — actual sales as % of BEP. Below 100% = losing money; 100-130% = barely above water; 150%+ = healthy margin. Indian retail chain DMart consistently operates at 200%+ BEP utilisation per store — their cost-discipline + traffic generation creates the safety margin. Loss-making chains (Shoppers Stop in earlier years, Trent in early Westside years) operated below 100% before pivoting strategy. BEP analysis is the early warning system every CFO should run monthly per business unit.
