Breakeven: what it is and what to do instead

The idea worth keeping

Not as boxes to fill, but as questions that fall out of the maths of the goal:

• What volume do we need, in the unit this business sells?
• What do similar operations actually achieve?
• How much room is there between breakeven and the expected volume?

Why reaching for it fails in an interview

• It is generic. Fixed cost divided by contribution can be computed for anything, and stopping there is not an answer.
• It misses the driver that matters. For a cinema, the question is the share of seats filled, at what times, which the formula alone does not test.
• It sounds rehearsed. Quoting the formula before knowing what the client is deciding sounds learned.

What to do instead: a worked case

1. 1

   Pin the question

   Decide whether the refit earns back its 600,000 cost quickly, and how full the recliners must be.

2. 2

   Write the maths of the goal

   • Ticket revenue per show = seats x occupancy x ticket price
   • Extra profit per year = shows per year x (new revenue per show minus old revenue per show); payback = refit cost / extra profit
3. 3

   Use what you know about the business

   • Most cinema seats are empty outside weekend evenings, so fewer, better seats lose little volume.
   • Premium formats raise ticket price and often snack spend, because guests come for an outing.
   • Similar premium screens in the chain's other cities show what occupancy is realistic.

   The structure that falls out of it

   • Revenue per show today
     • 200 seats
     • Occupancy
     • Ticket price
   • Revenue per show after
     • 100 recliners
     • Occupancy
     • Premium price
   • Payback
     • Refit cost
     • Shows per year

   Hypothesis: Because most seats are empty most of the time, halving seats loses little, and the higher price should pay back within about two years.

4. 4

   Find the facts that decide it

   • Today: 200 seats x 30% x 10 = 600 per show. After: 100 recliners x 45% x 18 = 810 per show, where 45% is what the chain's premium screens fill elsewhere.
   • At 1,500 shows a year, the extra is 1,500 x 210 = 315,000 a year, so payback = 600,000 / 315,000, about 1.9 years. Breakeven against today: 600 / 18 = about 33 recliners a show, or 33% occupancy.
5. 5

   Say so what

   Fit the recliners: at the 45% occupancy premium screens reach elsewhere, the screen earns 315,000 more a year and pays back in about 1.9 years, and it only needs 33% occupancy to match today's revenue. Track occupancy on weekday shows, where it is lowest. The risk is a weak film slate, which affects every screen alike.

Build the acumen behind it

The worked case used two things a list cannot give you: the five moves, and knowing how this kind of business makes money. These pages teach both.
