Market Cap Formula — How to Calculate
Market Capitalisation = Current Share Price × Total Shares Outstanding
Free Float Market Cap = Market Cap × (Free Float % ÷ 100)
Enterprise Value (EV) = Market Cap + Total Debt − Cash & Equivalents
Example: ₹2,400 × 250 Cr shares = ₹6,00,000 Cr (₹6 Lakh Cr) Market Cap
Free Float Market Cap = Market Cap × (Free Float % ÷ 100)
Enterprise Value (EV) = Market Cap + Total Debt − Cash & Equivalents
Example: ₹2,400 × 250 Cr shares = ₹6,00,000 Cr (₹6 Lakh Cr) Market Cap

Market Cap vs Enterprise Value — Key Difference
Market Cap is what the stock market values the equity at. Enterprise Value (EV) is what it would actually cost to buy the entire business — including paying off its debt but receiving its cash. EV is used in EV/EBITDA, EV/Sales, and acquisition pricing.
Enterprise Value = Market Cap + Total Debt − Cash & Equivalents
Example: MCap ₹6,00,000 Cr + Debt ₹1,000 Cr − Cash ₹500 Cr = EV ₹6,00,500 Cr
EV is what an acquirer would pay for 100% of the business
Example: MCap ₹6,00,000 Cr + Debt ₹1,000 Cr − Cash ₹500 Cr = EV ₹6,00,500 Cr
EV is what an acquirer would pay for 100% of the business
A company with ₹5,000 Cr market cap but ₹20,000 Cr debt actually has a much higher enterprise value — the acquirer would inherit the debt. Conversely, a company with huge cash (like Infosys) has EV significantly lower than market cap.
Free Float Market Cap — Why It Matters for Indices
Nifty 50 and Sensex are free-float weighted indices — they only count shares available for public trading, not promoter-held shares. A stock with 60% promoter holding only contributes 40% of its market cap to the index. This is why a large company with high promoter holding has less index influence than its total market cap suggests.
| Company (Example) | Total MCap | Promoter Holding | Free Float % | Index Weight Contribution |
|---|---|---|---|---|
| High Promoter (PSU example) | ₹3 Lakh Cr | 65% | 35% | Lower weight |
| Low Promoter (widely held) | ₹3 Lakh Cr | 25% | 75% | Higher weight |
| No promoter (HDFC Bank post-merge) | ₹12 Lakh Cr | ~0% | ~100% | Full weight in index |
Frequently Asked Questions
Does market cap equal the total value of a company?▾
Market cap is the stock market's valuation of the equity — how much all the shares are worth at the current price. It's not the same as the company's total value (Enterprise Value) because it ignores debt and cash. A company with ₹1,000 Cr market cap but ₹5,000 Cr in debt effectively requires ₹6,000 Cr to acquire outright. Market cap also reflects market sentiment and expectations, not just book value — which is why it fluctuates daily.
How does SEBI classify large cap, mid cap and small cap in India?▾
SEBI's AMFI (Association of Mutual Funds in India) publishes an official list twice yearly (January and July). Large cap = Top 100 companies by average 6-month market cap. Mid cap = 101st to 250th companies. Small cap = 251st company onwards. This classification matters for mutual funds — SEBI mandates that large cap funds invest at least 80% in large cap stocks. The cutoffs shift over time as markets rise or fall — what was mid cap 5 years ago may now be large cap.
Why do small cap stocks have higher return potential but more risk?▾
Small caps can deliver higher returns because: (1) They start from a smaller base — a ₹500 Cr company growing to ₹2,000 Cr is 4× vs a large cap going from ₹1 Lakh Cr to ₹4 Lakh Cr. (2) They're less followed by institutional analysts — mispricing opportunities exist. (3) They can grow faster in niche markets. But risks include: lower liquidity (hard to exit), less information disclosure, promoter-driven business dependence, higher volatility, and more vulnerability to economic downturns. The Nifty Smallcap 250 index has outperformed Nifty 50 over 10 years but with far greater drawdowns.
What is free float and why does it matter?▾
Free float is the percentage of shares available for open market trading — excluding shares held by promoters, government, and strategic investors who are unlikely to sell. It matters for: (1) Index weighting — Nifty and Sensex use free-float market cap, not total market cap. (2) Liquidity — low free float means fewer shares trade daily, causing higher price impact for large orders. (3) Volatility — stocks with low free float (under 25%) can be more volatile as small trades move prices significantly. SEBI requires a minimum 25% public float for listed companies.
Can market cap be used to compare companies across sectors?▾
Market cap itself is comparable across sectors for size — but P/E, P/B, and EV/EBITDA multiples vary hugely by sector. A ₹50,000 Cr bank and a ₹50,000 Cr FMCG company are the same "size" but have very different valuation metrics. Banks trade at P/B (Price/Book) multiples; FMCG at P/E; tech companies at EV/Revenue or EV/EBITDA. Market cap is a sizing tool, not a valuation tool — always combine with sector-appropriate multiples.
What is the Buffett Indicator (Market Cap to GDP)?▾
The Buffett Indicator = Total Stock Market Cap ÷ GDP. Warren Buffett called it "probably the best single measure of where valuations stand at any given moment." For India: the total NSE market cap divided by India's GDP. Historically, values above 100% suggest the market is expensive relative to the economy; below 75% suggests undervaluation. India's market cap crossed 100% of GDP for the first time around 2021, signaling elevated valuations. As of recent data, India's market cap/GDP ratio is approximately 90–110%.
