Break-even Analysis for Small Businesses (With Example)
By BizToolsIndia Editorial Team · Updated · Business Calculators
Quick answer
Break-even units = fixed costs ÷ (selling price − variable cost per unit). A café with ₹1,20,000 of monthly fixed costs, an average bill of ₹150 and ₹60 of variable cost per bill must serve 1,334 bills a month — about 45 a day — before it makes any profit.

Step 1: separate fixed and variable costs
| Fixed (per month) | Variable (per sale) |
|---|---|
| Rent, salaries, loan EMIs | Raw materials, ingredients |
| Electricity base charges, internet | Packaging, delivery |
| Software subscriptions, insurance | Card/UPI fees, marketplace commission |
Step 2: work out contribution
Contribution per unit = Selling price − Variable cost per unit
Break-even units = Fixed costs ÷ Contribution per unit
In the café example, each ₹150 bill contributes ₹90 towards fixed costs. ₹1,20,000 ÷ ₹90 = 1,333.3, so 1,334 bills a month.
Step 3: test what-if scenarios
Raise the average bill to ₹170 and contribution rises to ₹110, cutting break-even to 1,091 bills (about 36 a day). Small changes to price or variable cost often move the break-even point more than cutting fixed costs. Try your own numbers in the Break-even Calculator.
Break-even in rupees of sales
Sometimes it's easier to think in sales value than units, especially if you sell many products. Use the contribution margin ratio — the share of each rupee of sales left after variable costs.
Contribution margin ratio = (Price − Variable cost) ÷ Price
Break-even sales (₹) = Fixed costs ÷ Contribution margin ratio
In the café example, each ₹150 bill leaves ₹90, a ratio of 60%. Break-even sales = ₹1,20,000 ÷ 0.60 = ₹2,00,000 a month.
Planning for a profit target
Units for target profit = (Fixed costs + Target profit) ÷ Contribution per unit
If the café owner wants ₹30,000 a month of profit: (1,20,000 + 30,000) ÷ 90 = 1,666.7, so 1,667 bills — about 56 a day over 30 days. The Break-even Calculator has a target-profit field for this.
Which lever moves break-even most?
| Change | Contribution per bill | Break-even bills / month |
|---|---|---|
| Base case | ₹90 | 1,334 |
| Raise average bill to ₹170 | ₹110 | 1,091 |
| Cut variable cost to ₹50 | ₹100 | 1,200 |
| Cut fixed costs to ₹1,00,000 | ₹90 | 1,112 |
Raising the average bill by ₹20 — through pricing, combos or add-ons — lowers break-even more than cutting ₹20,000 of fixed costs. Test each lever with your own numbers before deciding where to focus.
Margin of safety
The margin of safety shows how far sales can fall before you make a loss. If the café actually serves 1,600 bills a month, its margin of safety is (1,600 − 1,334) ÷ 1,600 = 16.6%. A thin margin of safety means a slow month or a rent increase could push the business into loss.
Margin of safety % = (Actual sales − Break-even sales) ÷ Actual sales × 100
Businesses with many products
A shop with hundreds of items can't calculate break-even per product. Use the overall contribution margin ratio instead: take last month's sales and variable costs (purchases, packing, delivery, card fees), work out the ratio, and divide fixed costs by it. Recalculate when your product mix changes, because selling more low-margin items raises the break-even sales figure.
Common mistakes
- Counting a cost as fixed when it rises with sales, such as delivery or commission.
- Leaving out the owner's salary or loan EMIs from fixed costs.
- Using GST-inclusive prices — use prices before GST.
- Assuming break-even volume is achievable without checking capacity: can the café actually serve 56 bills a day?
Worked example 2: a services agency
Break-even works for services too; the “unit” is an hour or a project. A small design agency has ₹3,00,000 of monthly fixed costs (salaries, rent, software). It bills clients ₹1,500 an hour and pays freelancers ₹300 for each hour they deliver.
Contribution per hour = 1,500 − 300 = ₹1,200
Break-even hours = 3,00,000 ÷ 1,200 = 250 hours a month
Break-even revenue = 250 × 1,500 = ₹3,75,000
With a team that can realistically bill 320 hours a month, the margin of safety is (320 − 250) ÷ 320 ≈ 22%. If utilisation drops — a client pauses, or staff are busy on unbillable work — the agency gets close to loss quickly. That's a strong argument for retainers and minimum-hour contracts.
Recovering a one-time investment
The same idea tells you how long a one-time cost takes to pay back. If the café spends ₹2,40,000 on a new coffee machine and fit-out, at ₹90 contribution per bill it needs 2,667 extra bills to recover the spend. At 20 extra bills a day, that's about four and a half months. Compare that with the machine's useful life and any loan EMI before you buy.
Using break-even to set a price
Turn the formula around to find the lowest price that covers your costs at the volume you expect to sell:
Break-even price = Variable cost per unit + Fixed costs ÷ Expected units
If the café expects 1,200 bills a month, the minimum average bill is 60 + 1,20,000 ÷ 1,200 = ₹160. Anything below that loses money at that volume; the gap above it is profit. Then check the result against what customers will actually pay.
A quick break-even worksheet
- List every monthly fixed cost: rent, salaries (including yours), utilities, software, insurance and loan EMIs.
- List the variable cost of one sale: materials, packaging, delivery, card or platform fees.
- Find the average selling price before GST.
- Contribution = price − variable cost; break-even = fixed costs ÷ contribution.
- Compare break-even with realistic sales and capacity, and recalculate each quarter.
The Break-even Calculator does the arithmetic and shows the revenue needed as well as the units.
Frequently asked questions
What is a margin of safety?
How far your actual sales are above break-even. If you sell 1,600 bills and break even at 1,334, your margin of safety is 266 bills, or about 17% of sales.
Should I include my own salary in fixed costs?
Yes. If the business needs to pay you, include a realistic salary; otherwise break-even looks better than it really is.
What is contribution margin?
Selling price minus variable cost per unit. It is the amount each sale contributes towards fixed costs and then profit.
Should loan EMIs be included in fixed costs?
For cash planning, yes — include the full EMI. For accounting profit, include only the interest part and depreciation on the asset.
How often should I recalculate break-even?
Whenever prices, costs or rent change, and at least every quarter for a growing business.
Can I use break-even analysis for a service business?
Yes. Use billable hours or projects as the unit: contribution per hour is the rate charged minus the variable cost of delivering that hour.
What is the break-even point formula?
Break-even units = fixed costs ÷ (selling price − variable cost per unit). Break-even sales in rupees = fixed costs ÷ contribution margin ratio.
Is break-even the same as payback period?
No. Break-even is the sales level at which a period's revenue covers its costs. Payback period is how long it takes to recover a one-time investment from the contribution it generates.
Which costs are fixed and which are variable for a restaurant?
Variable costs rise with each order: ingredients, packaging, delivery-app commissions and card fees. Fixed costs stay the same whatever you sell: rent, salaried staff, equipment EMIs, licences and most utilities. Staff paid per shift sit in between — treat them according to how you actually schedule them.
