A 4-for-1 split turns 10,000,000 shares at $50 into 40,000,000 shares at $13, an illustrative baseline used across this site, not a specific company's real share count. A 10,000-share position becomes 40,000 shares, with position value and ownership percentage unchanged by the split alone.
| Metric | Before | After |
|---|---|---|
| Shares outstanding | 10,000,000 | 40,000,000 |
| Your position (illustrative) | 10,000 | 40,000 |
| Price per share (illustrative) | $50 | $13 |

How the ratio works
4-for-1 means 4 new shares for every 1 old share. Because the numerator is larger than the denominator, the share count rises and the mechanical price falls by the same factor. The invariant to check: shares times price should be the same before and after, aside from rounding.
A split changes units, not value. Ownership dilution comes from new share issuance (an offering, warrant exercise, or ATM program), which this calculator models separately.
