Bonus and right share calculator

On the book closure day the price is divided by one plus the bonus, so the company is worth the same over more shares: after a 10% bonus, a Rs 500 share is Rs 454.55.

The right shares bring in their price, so the adjusted price is the old price plus the right times the right share's price, over one plus the right: a 20% right at Rs 100 on a Rs 500 share gives Rs 433.33.

Adjusted price = (price + right × right share price) ÷ (1 + bonus + right), with the bonus and the right as shares for each share held. A 10% bonus and a 20% right at Rs 100 on a Rs 500 share gives Rs 400.00.

The adjusted price is where trading starts after the book closure. Buyers and sellers move it from there.
