Graham Number Calculator
The Graham Number, developed by Benjamin Graham (Warren Buffett's mentor), gives the maximum fair value of a stock using just two inputs. Any stock trading below its Graham Number is considered potentially undervalued using classic value investing principles.

❓ Stock Market Calculators — FAQs
What is the Graham Number and how is it calculated?▾
The Graham Number is a fundamental analysis formula developed by Benjamin Graham — Warren Buffett's mentor — to determine the maximum fair value of a stock. Formula: Graham Number = √(22.5 × EPS × Book Value Per Share). A stock trading below its Graham Number is considered potentially undervalued. For example, if EPS = ₹50 and BVPS = ₹400, Graham Number = √(22.5 × 50 × 400) = √4,50,000 ≈ ₹670. Use our Graham Number Calculator for any NSE/BSE stock.
How is PE ratio calculated for Indian stocks?▾
PE Ratio = Current Market Price ÷ Earnings Per Share (EPS). For example, if a stock trades at ₹500 and EPS is ₹25, PE = 500 ÷ 25 = 20. The Nifty 50 average PE has historically ranged between 18–24×. A PE below 15 is generally considered cheap for quality businesses, though sector comparison is essential — IT stocks typically trade at 25–35× PE, while PSU banks at 5–10×.
How do I calculate options profit in India?▾
Options profit for call options = (Current Price − Strike Price − Premium Paid) × Lot Size, when the current price exceeds the strike price. For put options, profit = (Strike Price − Current Price − Premium Paid) × Lot Size. In India, Nifty 50 lot size is 25 and Bank Nifty lot size is 15 (verify on NSE for current lot sizes as they change). Our Options Profit Calculator handles Nifty, Bank Nifty and individual stock options.
What is CAGR and how do I calculate it for stocks?▾
CAGR (Compound Annual Growth Rate) measures annualised return. Formula: CAGR = (Ending Value ÷ Beginning Value)^(1 ÷ Years) − 1. For example, if you invested ₹1 lakh and it grew to ₹1.8 lakh in 5 years, CAGR = (1.8)^(0.2) − 1 = 12.47% per year. The Nifty 50 has delivered approximately 13.4% CAGR over the last 10 years (June 2016 to June 2026).
What is the LTCG tax on stocks and mutual funds in India 2026?▾
Long-Term Capital Gains (LTCG) on equity shares and equity mutual funds held for more than 1 year are taxed at 12.5% (revised from 10% by Budget 2024, effective July 23, 2024). The first ₹1.25 lakh of LTCG per year is exempt. Short-Term Capital Gains (STCG) on equity are taxed at 20% (revised from 15%). F&O profits are taxed as business income at your applicable slab rate.
What is the Margin of Safety in value investing?▾
Margin of Safety (MOS) = ((Intrinsic Value − Market Price) ÷ Intrinsic Value) × 100. Benjamin Graham recommended buying only when MOS is at least 33–50%. A higher MOS reduces downside risk if your intrinsic value estimate is wrong. For example, if intrinsic value = ₹100 and market price = ₹65, MOS = 35% — within Graham's safe zone. Use our Margin of Safety Calculator for NSE stocks.
Why Indian Investors Need Specialized Stock Market Calculators
The Indian equity market has unique characteristics that make standard global tools inadequate for NSE/BSE investors: all values are in INR, tax calculations follow Indian LTCG/STCG/STT rules (updated by Budget 2024 with new 12.5% LTCG and 20% STCG rates), lot sizes for F&O are set by NSE/SEBI, and fundamental analysis benchmarks (like Nifty 50 average PE) differ from US/European markets.
Our Graham Number Calculator, Options Profit Calculator and Brokerage Calculator are built specifically for Indian market participants — incorporating NSE charges, Zerodha/Groww fee structures and Indian tax rates.
Value Investing in India — Benjamin Graham's Legacy
Benjamin Graham's value investing framework — the foundation of the Graham Number, Margin of Safety, and Intrinsic Value calculations — has proven highly applicable to Indian equities. Several Indian value investors have built multi-decade track records using these principles on NSE/BSE-listed companies.
The Indian market often provides large valuation gaps, especially in PSU, mid-cap and small-cap segments, where Graham Number discounts of 30–50% are not uncommon during market corrections. Our PE Ratio, ROE and PEG Ratio calculators help identify these opportunities systematically.
