How to use

Enter your shares, price and the split ratio, then click Adjust. Everything runs in your browser.

How does a split change my shares?

A 4-for-1 split turns 100 shares at $400 into 400 shares at $100 — same total value.

Does it work for reverse splits?

Yes — enter e.g. 1-for-10 and it consolidates the same way.
