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 1 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' health. The FCF payout ratio measures the percent of free cash flow devoted toward paying the dividend. Again, a ratio greater than 80% could be a red flag.

Let's examine Cal-Maine Foods(Nasdaq: CALM) and three of its peers.

Company

Yield

Interest Coverage

EPS Payout Ratio

FCF Payout Ratio

Cal-Maine Foods 6.7% 13.6 33.4% 45.6%
Archer Daniels Midland (NYSE: ADM) 2.1% 5.6 18.8% -5.3%
The Andersons (Nasdaq: ANDE) 1.1% 4.4 10.1% -1.4%
Bunge (NYSE: BG) 1.3% 3.9 5.7% -7%

With an interest coverage of 13.6, Cal-Maine Foods covers every $1 in interest expenses with $13.60 in operating earnings. Given that its EPS payout ratio and FCF payout ratio are below 50%, you shouldn't have to worry that Cal-Maine Foods will need to cut its dividend anytime soon.
