Pooja opens a small salon in Nagpur. Rent, two stylists, power and water come to ₹1 lakh a month.
A haircut costs ₹250. Shampoo, products and washing the towels cost about ₹50. That leaves ₹200 on every cut.
On her first Sunday, 16 customers walk in. Both chairs are busy all day. She goes home happy.
She lost about ₹800 that day.
A full salon isn’t always a profitable one. The question is how full.
What’s going on
This is the break-even point: the number of sales at which what each sale leaves over exactly covers your fixed costs. Below it, you lose money. Above it, you keep some.
The maths is simple. Divide your fixed costs by what each sale leaves:
₹1,00,000 ÷ ₹200 = 500 haircuts a month.
Open 25 days, that’s 20 a day. Pooja’s busy Sunday was four customers short.
Walter Rautenstrauch, an engineering professor at Columbia University, helped develop the break-even chart and set it out in his 1930 book The Successful Control of Profits. It draws two lines against how much you sell. Costs start at the fixed bills. Sales start at zero, but climb faster.
Where the lines cross, the losing stops.
Think of a mela stall
At a Diwali mela, a stall costs ₹3,000 for the evening, whether you sell one plate or five hundred. Each plate of pani puri leaves you ₹30 after its own costs.
So the first hundred plates pay for the stall. From the hundred-and-first, the money is yours.
Where you’ll spot it
- “Minimum 200 plates.” Caterers set a floor because below it, the cooks, the gas and the truck aren’t covered.
- Airlines. They track a break-even load factor: how full a plane must be before a flight stops losing money.
The catch
Breaking even every month isn’t the same as getting your money back. Pooja spent ₹6 lakh on chairs, mirrors and the fit-out before her first customer.
At 20 customers a day, the month’s bills are paid, and nothing more. Only the customers after the 20th pay back that ₹6 lakh. At 25 a day, that’s ₹25,000 a month, or two years to earn it back.
How to use it
- Add up the bills that come anyway. Rent, salaries, EMIs.
- Work out what one sale leaves after its own costs.
- Divide the first by the second, then by the days you’re open.
Then play with the numbers. A ₹50 discount sounds small. It cuts ₹200 a haircut to ₹150 and lifts the target from 20 customers a day to 27. A ₹50 price rise drops it to 16.
Before adding any monthly bill, ask: how many more sales will this need? A ₹20,000 hire means 100 more haircuts a month, 4 more a day.
Busy is a feeling. Break-even is a number.
