Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | Price change | Dollar change |
|---|---|---|
| $150 to $180 | 20.00% | 30 |
| $80 to $60 | -25.00% | -20 |
| $25 to $42 | 68.00% | 17 |
| $420 to $500 | 19.05% | 80 |
How This Calculator Works
Enter the earlier and the current share price. The calculator subtracts one from the other for the dollar change and divides by the earlier price to give the percentage. The result is the price-only move between the two dates, not a total return.
The Formula
Percentage Change
Old is the starting value, New is the ending value
Worked Example
A stock rising from $150 to $180 is a 20% price gain — $30 a share. On 100 shares, that is $3,000 of paper profit, before any dividends and before tax on a sale.
Key Insight
Price change is only part of a stock's total return. A share that pays a steady 4% dividend can finish a flat year up 4% on a total-return basis even though the price did not move — use a total-return figure to compare investments fairly.
Frequently Asked Questions
How is stock price change calculated?
Subtract the earlier price from the current price for the dollar change, then divide by the earlier price and multiply by 100 for the percentage change.
Does this include dividends?
No. It is a price-only change. For total return, add the dividends received during the period to the gain before dividing by the starting price.
What about stock splits?
A split changes the share count and price without changing value, so the calculator's figure is wrong if a split happened in the period. Use split-adjusted prices on both ends.
Is this an annual rate?
No. It is the total change between two dates. For an annualized rate, use a CAGR calculator on the same two prices and the years between them.
Can the change be negative?
Yes. If the current price is below the earlier one, the result is a negative percentage and a negative dollar change — the share has fallen by that share of value.

Methodology & Review
The change is the new price minus the old price; the percentage is that change divided by the old price. Dividends, splits, and corporate actions are not accounted for — for a total-return figure, use a stock return calculator.
