Quick guide
How to read a corporate-action ratio
1:1 bonus: you receive 1 new share for every 1 share you already own. 100 shares become 200.
2-for-1 split: every 1 old share becomes 2 new shares. 100 shares become 200.
1-for-10 reverse split: every 10 old shares become 1 new share. 1,000 shares become 100.
10% stock dividend: you receive additional shares equal to 10% of your existing holding.
FAQ
Bonus shares & stock split questions
How do I calculate shares after a 1:1 bonus issue?
A 1:1 bonus gives one additional share for every share held. If you own 100 shares before the bonus, the mechanical post-bonus holding is 200 shares.
Does a stock split increase my investment value?
Not by itself. A stock split changes the number of shares and mechanically adjusts the theoretical price per share. Market prices can move independently after the event.
How does a reverse stock split work?
A reverse split combines old shares into fewer new shares. In a 1-for-10 reverse split, every 10 old shares become 1 new share.
Can this calculator handle NSE, BSE, NYSE and Nasdaq stocks?
Yes. Choose the relevant market mode. The calculator changes the terminology and supported corporate-action types while keeping the underlying arithmetic consistent.
Is the adjusted price the actual opening price after the split?
No. It is a theoretical mechanical adjustment based on holding value. Actual traded prices can differ because the market continues to move.
