### How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Share Price Ã· Earnings per Share (EPS)

Or for FLIR Systems:

P/E of 25.18 = \$51.56 Ã· \$2.05 (Based on the year to June 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each \$1 of company earnings. 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 FLIR Systems's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. You can see in the image below that the average P/E (20.3) for companies in the electronic industry is lower than FLIR Systems's P/E.

That means that the market expects FLIR Systems will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

### How Growth Rates Impact P/E Ratios

P/E ratios primarily reflect market expectations around earnings growth rates. That's because companies that grow earnings per share quickly will rapidly increase the 'E' in the equation. That means even if the current P/E is high, it will reduce over time if the share price stays flat. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

FLIR Systems's earnings made like a rocket, taking off 128% last year. Having said that, if we look back three years, EPS growth has averaged a comparatively less impressive 14%.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

The 'Price' in P/E reflects the market capitalization of the company. Thus, the metric does not reflect cash or debt held by the company. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

While growth expenditure doesn't always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### FLIR Systems's Balance Sheet

FLIR Systems's net debt is 7.1% of its market cap. It would probably trade on a higher P/E ratio if it had a lot of cash, but I doubt it is having a big impact.

### The Verdict On FLIR Systems's P/E Ratio

FLIR Systems has a P/E of 25.2. That's higher than the average in its market, which is 17.8. While the company does use modest debt, its recent earnings growth is superb. So to be frank we are not surprised it has a high P/E ratio.
