Change in Index Calculator

Formula

The formula to calculate the change in index (ΔI) is:

\[ \Delta I = \frac{I_f - I_i}{I_i} \]

Where:

\( \Delta I \) is the change in index.
\( I_f \) is the final index value.
\( I_i \) is the initial index value.

What is Change In Index?

Change in index refers to the relative change in a specific index value over a period of time. This can be applied to various fields such as finance, economics, and science. For instance, in finance, it can refer to the change in a stock market index, while in science, it might refer to changes in an index measuring a particular property or phenomenon.
