P/E Ratio Calculator | Price-to-Earnings Ratio

P/E Ratio Calculator: calculate price-to-earnings ratio from price per share and earnings per share, or solve for a missing value.

This P/E ratio calculator helps you calculate price-to-earnings ratio from price per share and earnings per share, or solve the formula in reverse. It also includes an optional helper block for deriving EPS from net income and shares outstanding.

P/E is one of the most widely used valuation multiples because it connects market price with earnings. It is most useful when compared with peer companies, the company’s own history, growth expectations, and sector norms.

P/E Ratio

$$\text{Market Price per Share} = \mathrm{P/E} \times \text{Earnings per Share (EPS)}$$

$$P = \mathrm{P/E} \times \mathrm{EPS}$$

$$\text{Earnings per Share (EPS)} = \frac{\text{Market Price per Share}}{\mathrm{P/E}}$$

$$\mathrm{EPS} = \frac{P}{\mathrm{P/E}}$$

$$\mathrm{P/E} = \frac{\text{Market Price per Share}}{\text{Earnings per Share (EPS)}}$$

$$\mathrm{P/E} = \frac{P}{\mathrm{EPS}}$$

P/E Ratio Calculator FAQ

What is the P/E ratio?
P/E stands for price-to-earnings ratio. It compares the market price per share with earnings per share and is used as a valuation multiple.

What is the P/E formula?
P/E = Price per share / Earnings per share. This calculator can also solve for price per share or EPS.

What does a high P/E ratio mean?
A high P/E can mean investors expect stronger future growth, but it can also indicate that the stock is expensive relative to current earnings.

When is P/E less useful?
P/E is less useful when earnings are negative, unusually volatile, or distorted by one-off items. In those cases, P/S, P/B, or cash-flow-based valuation may be more informative.

How should I interpret P/E ratio?
A higher P/E usually reflects higher growth expectations, lower perceived risk, or richer valuation. It is most useful when compared with peers, historical averages, growth outlook, and business quality.
