Operating Income
Operating profit is similar to EBITDA as it’s used a profitability metric. But, it includes depreciation and amortization.
So Operating Profit = Revenue - COGS - OpEx - D&A
And EBITDA = Revenue - COGS - OpEx
or EBITDA = Operating Profit + D&A
So if we have a company with:
- Revenue: $200
- COGS: $50
- OpEx: $100
- D&A: $50
Operating Profit = 200 - 50 - 100 - 50 = $0
EBITDA = 200 - 50 - 100 = $50 OR EBITDA = 0 + 50 = $50
In the room
Interviewers use operating income to check whether you actually understand D&A. If you can rattle off that EBITDA equals operating income plus D&A, and explain why that add-back matters, you've answered two questions at once.
