How can I calculate index?

In the case outlined, the percentage change from Year 3 (index 110) to Year 12 (index 120) would represent a 10% increase. This metric offers a concise representation of the growth or decline over the specified timeframe.

Index data operates on a foundational base, often set at 100, serving as a reference point for comparison. This baseline is devoid of specific units, allowing for a generalized assessment of performance.

When determining the percentage change from the established base, a straightforward calculation involves subtracting 100 from the index value. For instance, if Year 1 is assigned an index of 100 and Year 3 registers an index of 110, the percentage increase from the base can be easily deduced.

Extending this logic, to calculate the percentage change over a longer period, such as from Year 3 to Year 12, one would compare the index values of these two years. Assuming Year 12 has an index of, say, 120, the percentage increase from Year 3 would be calculated accordingly.
