A stock split divides existing shares into a larger number of shares by reducing the face value. The split ratio equals the original face value divided by the new face value. Your total investment value remains exactly the same.
- Split Ratio = Old Face Value / New Face Value
- New Shares = Current Shares x Split Ratio
- New Price = Current Price / Split Ratio
Common Stock Split Ratios
| Old FV | New FV | Ratio | 100 Shares Become |
|---|---|---|---|
| Rs 10 | Rs 5 | 1:2 | 200 shares |
| Rs 10 | Rs 2 | 1:5 | 500 shares |
| Rs 10 | Rs 1 | 1:10 | 1,000 shares |
| Rs 5 | Rs 1 | 1:5 | 500 shares |
Key Point: Stock splits do not create or destroy value. Your 100 shares at Rs 1,000 each (Rs 1 lakh total) become 500 shares at Rs 200 each after a 1:5 split (still Rs 1 lakh). The split simply makes shares more affordable and liquid for retail investors.

Frequently Asked Questions
A stock split increases the number of outstanding shares by reducing the face value per share, while the total investment value remains unchanged. This calculator takes your current shares, the original face value, and the new face value to compute the split ratio, new number of shares, and price adjustment factor. For example, a face value change from Rs 10 to Rs 2 is a 1:5 split.
Companies split stocks to make shares more affordable for retail investors. A stock trading at Rs 5,000 becomes Rs 500 after a 1:10 split, attracting more buyers. Splits improve liquidity (higher trading volume), reduce the bid-ask spread, and can signal management confidence. The company market capitalization and each shareholder total value remain unchanged immediately after the split.
Split ratio = Original Face Value / New Face Value. If face value changes from Rs 10 to Rs 5, the ratio is 1:2 (each share becomes 2). From Rs 10 to Rs 2, the ratio is 1:5. From Rs 10 to Rs 1, the ratio is 1:10. The share price adjusts inversely: in a 1:5 split, a Rs 500 stock becomes Rs 100 per share.
No. A stock split does not change your total investment value. If you held 100 shares at Rs 500 each (total Rs 50,000) and a 1:5 split occurs, you now have 500 shares at Rs 100 each (still Rs 50,000). Neither the market capitalization of the company nor your portfolio value changes due to a split. It is similar to exchanging a Rs 500 note for five Rs 100 notes.
Your average cost per share is divided by the split ratio. If your average cost was Rs 400 and the stock splits 1:5, your new average cost is Rs 80 per share. Use our stock average calculator to recalculate your cost basis after adjusting for the split.
A reverse split consolidates shares, reducing the total count while increasing the price per share. For example, a 5:1 reverse split converts 500 shares at Rs 10 into 100 shares at Rs 50. Companies do reverse splits when their stock price is very low, risking delisting. Reverse splits are generally viewed negatively as they often indicate the company is struggling.
Stock splits do not trigger a taxable event. You simply adjust the cost basis by dividing by the split ratio. Your holding period remains from the original purchase date. When you eventually sell, capital gains are calculated using the adjusted cost. For example, shares bought at Rs 500 before a 1:5 split have an adjusted cost of Rs 100 for LTCG/STCG computation.
Common split ratios in India are 1:2 (Rs 10 to Rs 5), 1:5 (Rs 10 to Rs 2), and 1:10 (Rs 10 to Rs 1). Some companies split from Rs 5 to Rs 1 (1:5) or Rs 2 to Rs 1 (1:2). The most aggressive splits result in Re 1 face value. Notable recent splits include Infosys (1:5), MRF (1:10), and various IT companies.
After the record date for the stock split, new shares are typically credited to your demat account within 2-3 weeks. The stock exchange adjusts the price on the ex-date (usually 1 day before record date). You can see the new quantity in your demat account once the corporate action is processed by NSDL/CDSL. Check your depository statement for confirmation.
Dividend per share is adjusted proportionally after a split. If a company was paying Rs 10 DPS and does a 1:5 split, the new DPS becomes Rs 2 per share. Since you hold 5x more shares, your total dividend income remains the same. However, companies sometimes use splits to increase total payouts, resulting in higher per-share dividends than the proportionally adjusted amount.
Stock splits are generally considered bullish signals because they indicate the management believes the stock price has risen enough to warrant making it more accessible. Companies with rising stock prices (and earnings) are more likely to split. Studies show stocks tend to outperform moderately after splits. However, a split alone does not change fundamentals, so any positive effect is largely psychological and liquidity-driven.
After a stock split, derivative contracts are adjusted proportionally. In a 1:5 split: option strike price is divided by 5, lot size is multiplied by 5, and open positions carry forward with adjusted terms. The exchange publishes the adjustment factor. Existing F&O positions are not closed. The adjustment ensures no profit or loss occurs purely from the split for derivative holders.
Yes, companies can split multiple times. For example, Infosys has split multiple times since listing: originally at Rs 10 face value, split to Rs 5, then to Rs 2, and then to Re 1. Each split compounds: after two 1:2 splits, the effective ratio is 1:4. Frequent splitters are typically high-growth companies whose stock prices keep appreciating to levels requiring adjustment.
A stock split divides existing shares into more pieces (reducing face value and price proportionally). Bonus shares issue new additional shares from reserves (face value unchanged, but total shares increase). Both increase share count without additional cost. The key difference is accounting: splits reduce face value while bonus shares reduce reserves. Use our bonus calculator for bonus share analysis.
Check for upcoming stock splits on: stock exchange websites (BSE/NSE corporate actions section), financial news portals (Moneycontrol, Economic Times), your broker app notifications, and company board meeting announcements. Stock exchanges publish a calendar of corporate actions including split record dates. Set alerts for stocks in your portfolio to stay informed about upcoming splits.
Face value (also called par value) has minimal practical significance for investors. A stock with Rs 10 face value and one with Re 1 face value can both trade at Rs 500. Face value determines the split ratio and is used for computing minimum dividend declarations. Market price is what matters for investment decisions. However, very low face value (Re 1) stocks appear cheaper numerically, attracting more retail participation.
If a split results in fractional shares (e.g., odd-lot adjustments), the company or registrar may credit the equivalent cash value or round up/down. In practice, most Indian stock splits are clean ratios that do not create fractions for standard lot holdings. If you hold an odd number before a split with a complex ratio, check the company corporate action terms for fractional share treatment.
Stock charts automatically adjust historical prices for splits, showing a continuous price line. A stock at Rs 5,000 that splits 1:10 will show Rs 500 on adjusted charts for all historical dates. This ensures technical analysis (moving averages, support/resistance levels) remains valid. Some platforms offer both adjusted and unadjusted chart views. Always use split-adjusted data for meaningful analysis.
From a value perspective, it does not matter since your total investment value is the same. However, stocks sometimes rally before a split announcement due to anticipation and improved accessibility attracting new buyers. Post-split, increased liquidity and lower price point may attract additional demand. The best approach is to buy based on fundamentals regardless of split timing.
EPS is adjusted proportionally after a split. If EPS was Rs 50 and a 1:5 split occurs, the new EPS becomes Rs 10. The P/E ratio remains unchanged since both price and EPS are divided by the same factor. Historical EPS in financial statements and analyst estimates are typically restated to reflect splits for consistent comparison across periods.
The Indian markets see dozens of stock splits annually, predominantly among mid-cap and small-cap companies. Recent notable splits include various IT companies splitting from Rs 5 to Rs 1, and manufacturing companies reducing face values. The trend has been toward lower face values (Rs 1 or Rs 2) to maximize accessibility. BSE and NSE publish complete lists of upcoming and past corporate actions including splits.
No, stock splits cannot directly lead to delisting. In fact, splits work in the opposite direction by improving liquidity and accessibility, which helps meet exchange listing requirements. Reverse splits (consolidation) are sometimes done to avoid delisting due to minimum price thresholds, but this is more common in US markets. In India, the minimum trading price is not a listing criterion.
After a stock split, update: (1) Number of shares held (multiply by split ratio). (2) Average cost per share (divide by split ratio). (3) Buy price entries in portfolio trackers. (4) Stop-loss and target price levels. (5) SIP amount if doing regular stock purchases. Most broker apps auto-adjust these records. For manual tracking, ensure all historical entries are split-adjusted.
Stock split does not affect market capitalization (Market Cap = Price x Total Shares). Since price decreases and shares increase proportionally, the product remains the same. The company ranking in indices like Nifty 50, BSE 500, etc. is unchanged. Market cap-based index weightage also remains the same. The split is purely cosmetic from a market cap perspective.
Stock splits are completely free for shareholders. There are no charges, fees, or tax implications. The split is processed automatically through the depository system, and new shares appear in your demat account. The company bears the administrative cost of the corporate action. You do not need to submit any application or documents.
The minimum face value for listed stocks in India is Re 1, as permitted by SEBI. Many companies have progressively split their face values down to Re 1 over the years. There is no minimum price at which a stock must trade. Face values of Re 1, Rs 2, Rs 5, and Rs 10 are the most common among listed Indian companies.
Rights issues after a split are priced based on the new post-split face value and market price. The rights ratio and pricing are determined independently of historical splits. However, the lower post-split price makes rights issues more accessible since the per-share cost is lower. Shareholders receive rights proportional to their post-split holdings.
As a shareholder, you can raise a resolution proposing a stock split at the Annual General Meeting. However, the decision ultimately rests with the company board of directors. Boards typically initiate splits when the stock price becomes too high for retail participation or when peer companies have lower share prices. Shareholder activism regarding splits is rare in India.
Lower post-split prices attract more retail investors, increasing the number of buyers and sellers at each price level (market depth). Better depth reduces impact cost (the price impact of large orders), tightens bid-ask spreads, and improves overall market efficiency. This is particularly beneficial for mid-cap and small-cap stocks that may have had limited liquidity before the split.
Pledged shares are automatically adjusted during a stock split. If you had 100 shares pledged and a 1:5 split occurs, 500 shares become pledged. The pledge value remains the same. The lender (bank or broker) records are updated by the depository. You do not need to take any action regarding pledged shares during a split.
Frequent stock splits indicate a company with consistently rising stock prices, which is a positive signal. Companies that have split multiple times over decades (like HDFC Bank, Asian Paints) demonstrate long-term price appreciation driven by earnings growth. However, splits should be viewed alongside financial metrics like revenue growth, profit margins, and ROE for comprehensive analysis.
In company books, a stock split reduces the face value per share and increases the number of shares. Total share capital (face value x shares) remains unchanged. No journal entry is required since it is a subdivision of existing shares. Unlike bonus issues, stock splits do not affect reserves, retained earnings, or any other balance sheet component. It is the simplest form of corporate action from an accounting standpoint.
The mechanism is the same, but terminology differs. US companies announce split ratios directly (2:1, 3:1, 10:1) while Indian companies typically announce face value changes (Rs 10 to Rs 2). US splits do not involve face value changes since US stocks often have no par value. The end result is identical: more shares at proportionally lower prices with unchanged total value.
Stock exchanges announce: the old and new face value, the split ratio, the record date (shareholders on this date receive split shares), the ex-date (trading price adjusts), and the credit date (new shares deposited in demat). This information is available on the BSE/NSE corporate actions page and is also disseminated through broker notifications and financial news.
Divide your pre-split target price by the split ratio. If your target was Rs 2,500 and the stock splits 1:5, the new target is Rs 500. Similarly, support and resistance levels, stop-losses, and all price-based technical indicators should be divided by the split ratio. Most charting platforms auto-adjust, but verify if you maintain manual records.
