Bonus Share / Stock Split Adjusted Price Calculator

Calculate your new share count and the price-adjusted-for-dilution figure after a bonus issue or a stock split. Toggle between the two — both redistribute the same total value over more shares, just via different mechanics.

How the Bonus Share / Stock Split Adjusted Price Calculator works

A bonus issuegives existing shareholders additional free shares in a fixed ratio (e.g. “1:2” = 1 new share for every 2 held) — it doesn't change the company's market capitalisation or the face value of each share, so the market price adjusts down proportionately to keep your total holding value unchanged.

A stock split reduces the face value of each share (e.g. from ₹10 to ₹2, a 5-for-1 split) and proportionately increases the number of shares you hold — again, market capitalisation and your total holding value are unaffected; only the number of shares and per-share price change.

Both are cosmetic restructurings of the same total value, often used to improve a stock's liquidity and make individual shares more affordable to smaller investors — neither event, by itself, changes the underlying business or your proportional ownership stake.

Frequently Asked Questions

Does a bonus issue or stock split make me richer?
No — both events redistribute the exact same total value over a larger number of shares. Your total holding value is unchanged immediately after the ex-date; only the number of shares and per-share price change.
What's the difference between a bonus issue and a stock split?
A bonus issue capitalises reserves into new shares at the same face value — the company issues genuinely new shares. A stock split simply divides the existing face value into smaller units, converting each existing share into multiple shares of lower face value, with no new capitalisation involved.
What is the cost basis of my bonus shares for tax purposes?
Bonus shares are typically treated as having zero acquisition cost for capital gains tax purposes in India, with their holding period generally starting from the bonus allotment date — the entire sale proceeds of a bonus share are usually taxed as capital gains. Consult a tax advisor for your specific situation.
Do I need to do anything to receive bonus shares or a split?
No — both are credited automatically to your demat account based on your holding as on the record date. You don't need to apply, unlike a rights issue.
