The formula used for finding the simple aggregate index numbers is:
\(\frac{\sum p_{ij}}{\sum p_{oj}} \times 100\)
The simple aggregate index compares the total current prices (\(\sum p_{ij}\)) to total base-year prices (\(\sum p_{oj}\)), expressed as a percentage. This measures overall price change without weighting.
