Determining operating leverage from a company's income statement

I would assume you would need to bring in the balance sheet to look at total debt and compare this to oincome in some fashion.

I am no accounting expert, so I could be way off.

Google is your friend here. Or Investopedia.

Depends on the amount of detail in the financials and your knowledge of the companies operations. It would also be much easier for companies in one line of business.

You would have to make judgements on what is a fixed cost vs. what is a variable cost. Those judgments would improve with your knowledge of the industry.

Operating leverage is not the same as financial leverage.

It depends on how detailed the income statement is. You just have to be able to see what is fixed and what is variable.

Can't do it with just income statement. In some cases can't figure it at all. Not trying to be aa jerk, but it's not just fixed and variable costs, it's also sales volume and margin.
