Stock Split Calculator

Share count and price after a split or reverse split. The total value does not change, which is the entire point and the thing most people are checking.

Also called: share split calculator, reverse split calculator.

Shares after the split
500

500 shares at ₹480 each. Your holding is still worth ₹2,40,000, because a split changes the slicing and not the pie.

How this is calculated

An estimate, not an offer or a guarantee. Projected returns assume the rate you entered holds for the whole term, which no market does.

Method and background

This is what the calculation gives for the numbers you entered. It is an estimate, not advice, and it knows nothing about your situation beyond those numbers. Rules for India change on a published schedule; the effective date is shown on every rule-based tool.

How this is calculated

A split multiplies the share count and divides the price by the same ratio, so the value of a holding is identical the moment before and after. Companies split to bring the price into a range retail buyers find comfortable, and reverse-split to lift it off an exchange floor. Neither creates or destroys value, whatever the price does afterwards for other reasons.

shares multiply by the ratio and price divides by it, so the value is unchanged
q
Shares before (shares)
n:o
New shares per old share (ratio)

Method and limits

What it assumes

  • No fractional-share cash adjustment, which some registrars apply.

What it deliberately does not model

  • Your cost basis per share divides by the same ratio, which matters for capital gains and is not computed here.

Frequently asked questions

Do I gain anything from a split?
No. You hold more shares worth proportionally less. Any price movement around a split comes from what the market reads into it, not from the split itself.
