What Is a Percent Increase?
A percent increase measures how much a value has grown relative to its original amount, expressed as a percentage. It is a useful metric for comparing changes over time, assessing performance, and analyzing trends.Formula for Percent Increase:
\[
\text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100
\]
This formula calculates the difference between the new and old values, divides by the original value to find the relative change, and then multiplies by 100 to convert it into a percentage.
