Did You Know?
PEG below 1 is the sweet spot
A stock at 30x P/E growing earnings at 35% has a PEG of 0.86 — potentially undervalued. A stock at 15x P/E but growing at 5% has a PEG of 3 — possibly expensive. PEG is more useful than P/E alone for growth stocks.

How to use this calculator

1

Enter share price and EPS

Use current market price and trailing 12-month EPS from the company financials or stock screener.

2

Enter expected growth

Analyst consensus 5-year EPS growth estimate. Used for PEG ratio calculation.

3

Select sector

Compare your stock P/E against the sector average to assess relative valuation.

The formula explained

P/E Ratio = Share Price / Earnings Per Share (EPS)
Earnings Yield = EPS / Share Price x 100
PEG Ratio = P/E Ratio / Expected EPS Growth Rate

P/E shows how much investors pay per rupee of earnings. PEG adjusts for growth — a PEG below 1 suggests undervaluation relative to growth. Earnings yield is the P/E inverse, useful for comparing stocks to bond yields.

Frequently Asked Questions

What is a good P/E ratio?

It depends entirely on the sector and growth rate. High-growth tech stocks trade at 40-100x. Mature utility stocks trade at 8-15x. Compare only within sectors, and use PEG ratio to adjust for growth.

What is the PEG ratio?

Price/Earnings to Growth ratio = P/E divided by expected EPS growth rate. PEG below 1 suggests the stock may be undervalued relative to growth. Peter Lynch popularised this as a quick valuation check.

What is earnings yield?

The inverse of P/E: EPS divided by price. A P/E of 20x means earnings yield of 5%. Compare against fixed deposit rates or bond yields to judge if equities are attractive.

Trailing vs forward P/E?

Trailing P/E uses last 12 months of actual earnings. Forward P/E uses projected earnings. This calculator uses trailing (actual) EPS. Forward P/E is more forward-looking but based on estimates that may be wrong.

What is a good PE ratio for stocks?

A PE below the industry average or below 15-20 is often considered undervalued. High-growth companies may have PE above 50. The PE ratio alone is insufficient — compare with sector peers and PEG ratio.
