### How Do I Calculate A Price To Earnings Ratio?

The formula for P/E is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for National Presto Industries:

P/E of 13.58 = \$78.320 ÷ \$5.769 (Based on the year to December 2019.)

(Note: the above calculation results may not be precise due to rounding.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. All else being equal, it’s better to pay a low price — but as Warren Buffett said, ‘It’s far better to buy a wonderful company at a fair price than a fair company at a wonderful price’.

### How Does National Presto Industries’s P/E Ratio Compare To Its Peers?

We can get an indication of market expectations by looking at the P/E ratio. The image below shows that National Presto Industries has a P/E ratio that is roughly in line with the aerospace & defense industry average (13.4).

National Presto Industries’s P/E tells us that market participants think its prospects are roughly in line with its industry. If the company has better than average prospects, then the market might be underestimating it. I would further inform my view by checking insider buying and selling., among other things.

### How Growth Rates Impact P/E Ratios

If earnings fall then in the future the ‘E’ will be lower. Therefore, even if you pay a low multiple of earnings now, that multiple will become higher in the future. Then, a higher P/E might scare off shareholders, pushing the share price down.

National Presto Industries’s earnings per share were pretty steady over the last year. But EPS is up 5.4% over the last 5 years. And over the longer term (3 years) earnings per share have decreased 1.4% annually. So we might expect a relatively low P/E.

### Don’t Forget: The P/E Does Not Account For Debt or Bank Deposits

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. So it won’t reflect the advantage of cash, or disadvantage of debt. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### How Does National Presto Industries’s Debt Impact Its P/E Ratio?

With net cash of US\$158m, National Presto Industries has a very strong balance sheet, which may be important for its business. Having said that, at 29% of its market capitalization the cash hoard would contribute towards a higher P/E ratio.

### The Bottom Line On National Presto Industries’s P/E Ratio

National Presto Industries’s P/E is 13.6 which is about average (13.0) in the US market. EPS was up modestly better over the last twelve months. And the healthy balance sheet means the company can sustain growth. But the P/E suggests shareholders have some doubts.
