Everyday basket (anchored to 2024 prices)

Inputs show the item’s price in the selected Spent at year, auto-derived from a 2024 anchor. Change a value to override. We then show the CPI-adjusted equivalent in the Cost at year.
📝 CPI-based equivalents for illustration—real shop prices vary by brand/location and promotions.

What this calculator does

This tool uses the World Bank’s annual CPI series (Consumer price index, 2010=100) for Sri Lanka (1960 → latest available year) to adjust a price across years:

pricetoYear = pricefromYear × (CPItoYear / CPIfromYear)

It’s best for long-run comparisons. If you need monthly, local indices (CCPI/NCPI, 2021=100), you’ll need a different series and a re-base.
