About this indicator

This tracks the average year-on-year change in retail prices across a fixed basket of goods and services, combining rural and urban consumption, so it captures cost-of-living pressure on households rather than growth or wages. Food and fuel swings often drive the headline number, which can move sharply from year to year even when the longer trend is stable. Watch that a lower inflation rate still means prices are rising, just more slowly, and that state-level retail inflation can diverge from the all-India figure.
