As a dividend investor, it pays to follow how much of a company's money goes toward funding its dividend. A nice yield now won't matter much if the company can't keep making those payments going forward.

Here, we'll highlight a given company and its closest competitors to see just how safe their dividends are, with a little help from three crucial tools:

  • The interest coverage ratio, or earnings before interest and taxes, divided by interest expense. The interest coverage ratio measures a company's ability to pay the interest on its debt. An interest coverage ratio less than 1.5 is questionable; a number less than one means that the company is not bringing in enough money to cover its interest expenses.
  • The EPS payout ratio, or dividends per share divided by earnings per share. The EPS payout ratio measures the percentage of earnings that go toward paying the dividend. A ratio greater than 80% is worrisome.
  • The FCF payout ratio, or dividends per share divided by free cash flow per share. Earnings alone don't always paint a complete picture of a business's health. The FCF payout ratio measures the percent of free cash flow devoted toward paying the dividend. Again, a ratio greater 80% could be a red flag.

Let's examine Cognex (Nasdaq: CGNX) and three of its peers.

Cognex does not has an interest coverage ratio since it does not have any debt to pay interest on. Given that its EPS payout ratio and FCF payout ratio are below 25%, you shouldn't have to worry that Cognex will need to cut its dividend anytime soon.
