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 DPL (NYSE: DPL) and three of its peers.

With an interest coverage ratio of 6.9, DPL covers every $1 in interest expenses with nearly $7 in operating earnings. Given its EPS payout ratio and FCF payout ratio are below 70%, you shouldn't have to worry that DPL will need to cut its dividend anytime soon.
