Stock split adjustment: Adjusting Shares and Price After a Split
A stock split changes the share count and the corresponding per-share price mechanically. It does not by itself create additional economic value.
Use the Stock split adjustment Calculator to enter your own figures and compare the result with the worked example below.
Stock split adjustment formula
New shares = Old shares × Split ratio
Worked example
| Item | Example value |
|---|---|
| Old shares | 100 shares |
| New shares per old share | 2 ratio |
| Old price | 50 USD |
| Stock split adjustment | 200 |
These are illustrative inputs, not current prices, rates or recommended targets. Where a currency is shown, keep all comparable money amounts in the same currency; conversion examples identify the two sides separately.
How to interpret the result
Apply the split ratio in the correct direction. Market movements after the split can change value independently of the adjustment.
