What Is Net Change?
Net change is the difference between a starting value and an ending value over a specific time period. It helps you understand how much something has increased or decreased.
Formula: Net Change=Ending Value−Starting Value\text{Net Change} = \text{Ending Value} – \text{Starting Value}Net Change=Ending Value−Starting Value
If the result is positive, it represents a gain or increase. If negative, it’s a decrease or loss.
Example of Net Change
Suppose a stock price increased from $150 to $175. The net change would be: 175−150=$25175 – 150 = \text{\$25}175−150=$25
That means the stock increased by $25.
Percentage Change Formula
In addition to net change, it’s useful to calculate the percentage change, which tells you how large the difference is in relative terms: Percentage Change=(Net ChangeStarting Value)×100\text{Percentage Change} = \left( \frac{\text{Net Change}}{\text{Starting Value}} \right) \times 100Percentage Change=(Starting ValueNet Change)×100
Using the same stock example: 25150×100=16.67%\frac{25}{150} \times 100 = 16.67\%15025×100=16.67%
So, the stock rose by 16.67%.
