What is Bonus Share Calculator?

A Bonus Share Calculator helps investors calculate the impact of bonus share issuance on their shareholding and cost basis. Bonus shares are additional free shares given to existing shareholders in proportion to their holdings. While you receive more shares, the stock price typically adjusts proportionally. This calculator shows your new total shares, adjusted average cost, and expected post-bonus share price.

How to Use This Calculator

  1. Enter your current number of shares held
  2. Input your average purchase price per share
  3. Add the current market price before bonus announcement
  4. Set the bonus ratio (e.g., 1:1 means 1 bonus share for every 1 held)
  5. View your new shareholding and adjusted cost basis

Formula Used

Bonus Shares = Current Shares × (Bonus Ratio New / Bonus Ratio Old) Total Shares After Bonus = Current Shares + Bonus Shares New Average Cost = (Current Shares × Purchase Price) / Total Shares Expected Post-Bonus Price = (Current Price × Current Shares) / Total Shares Examples: 1:1 Bonus = 1 bonus share for every 1 held (doubles holdings) 1:2 Bonus = 1 bonus share for every 2 held (50% increase) 2:1 Bonus = 2 bonus shares for every 1 held (triples holdings)

Example Calculation

Example: 1:1 Bonus Issue Before Bonus: - Shares Held: 100 - Average Cost: ₹500 per share - Current Price: ₹1,000 per share - Investment Value: ₹50,000 - Market Value: ₹1,00,000 After 1:1 Bonus: - Bonus Shares Received: 100 (free) - Total Shares: 200 - New Average Cost: ₹50,000 / 200 = ₹250 per share - Expected New Price: ₹1,000 × (100/200) = ₹500 per share - Market Value: 200 × ₹500 = ₹1,00,000 (Unchanged) Your shareholding doubled, average cost halved, and market price adjusted proportionally.

Frequently Asked Questions

Do bonus shares affect my investment value?

No! Bonus shares don't add real value. If you owned ₹1 lakh worth before bonus, you'll still own ₹1 lakh after bonus (theoretically). The stock price adjusts downward proportionally to compensate for increased shares. However, improved liquidity and positive market sentiment can drive prices higher post-bonus.

Why do companies issue bonus shares?

Companies issue bonus shares to: 1) Reward shareholders without paying cash dividends, 2) Convert reserves into equity capital, 3) Improve stock liquidity by reducing per-share price, 4) Signal strong financial position and future growth confidence, 5) Increase retail participation with more affordable prices.

How are bonus shares taxed in India?

Bonus shares received are NOT taxed at the time of receipt. They're considered a capital receipt. Tax applies only when you sell them. The cost of acquisition is considered ZERO for bonus shares. Holding period starts from the date of allotment for determining STCG vs LTCG.

What happens to my average cost after bonus?

Your total cost basis remains same, but it's now spread across more shares, reducing average cost per share. Example: Bought 100 shares at ₹500 (₹50K total). After 1:1 bonus, you have 200 shares. New average: ₹50K / 200 = ₹250 per share. This is important for calculating capital gains.

When will bonus shares be credited to my demat?

Check the record date. If you hold shares on record date, you're eligible. Bonus shares are typically credited within 15-30 days after the record date. The exact date is mentioned in the bonus announcement. Your broker will automatically update your holdings.

Is receiving bonus shares better than dividends?

Depends on your needs! Bonus shares don't provide immediate cash but offer tax advantages - no tax at receipt, only on sale. Dividends provide cash but are taxed at your slab rate immediately. For long-term wealth building, bonus shares are often better. For income needs, dividends are preferable.

Can I sell bonus shares immediately?

Yes! Once bonus shares are credited to your demat account, you can sell them anytime. However, consider: 1) Wait for 12 months for LTCG benefits, 2) Stock price typically takes time to stabilize post-bonus, 3) Company fundamentals matter more than corporate actions for selling decisions.
