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

The formula for price to earnings is:

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

Or for Tate & Lyle:

P/E of 16.97 = Â£6.64 Ã· Â£0.39 (Based on the year to March 2019.)

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

A higher P/E ratio means that investors are paying a higher price for each Â£1 of company earnings. That is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

### Does Tate & Lyle Have A Relatively High Or Low P/E For Its Industry?

Tate & Lyle'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

Probably the most important factor in determining what P/E a company trades on is the earnings growth. Earnings growth means that in the future the 'E' will be higher. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.

Tate & Lyle's earnings per share fell by 31% in the last twelve months. But it has grown its earnings per share by 15% per year over the last three years. And it has shrunk its earnings per share by 5.8% per year over the last five years. This might lead to muted expectations.

### 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. In other words, it does not consider any debt or cash that the company may have on the balance sheet. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Tate & Lyle's Balance Sheet

Net debt totals just 9.6% of Tate & Lyle's market cap. The market might award it a higher P/E ratio if it had net cash, but its unlikely this low level of net borrowing is having a big impact on the P/E multiple.

### The Verdict On Tate & Lyle's P/E Ratio

Tate & Lyle has a P/E of 17.0. That's around the same as the average in the GB market, which is 17.0. Given it has some debt, but didn't grow last year, the P/E indicates the market is expecting higher profits ahead for the business.

Investors have an opportunity when market expectations about a stock are wrong. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
