To calculate EBITDA, you need to start with a company's revenue and subtract its cost of goods sold.
Then, you subtract its operating expenses (like salaries and rent).
This gives you the company's EBITDA.
Example:
Let's say you and your friends sell lemonade from a stand.
You make $20 selling lemonade, but you spent $5 on lemons, sugar, and cups.
You also spent $5 on flyers to advertise your lemonade stand.
To calculate your EBITDA, you would start with the $20 you made selling lemonade, and subtract the $5 you spent on lemons, sugar, and cups.
This leaves you with $15. Then, you would subtract the $5 you spent on advertising.
This leaves you with an EBITDA of $10.
