Generated from May 2025's observations.
As of May 2025, the Basket Index for a US family of 4 sits at 129.9 — meaning the cost of a standard household basket has risen 2.3% versus a year ago and is up 0.03% from the previous month.
Most of the move comes from rent of primary residence, eggs (grade a, large), ground beef (100% beef) and electricity (residential). Together these items account for roughly 76% of the year-over-year basket cost change.
Offsetting the increases: gasoline (regular unleaded) (-12.6%), bread (white loaf) (-4.8%) are cheaper than a year ago.
Inflation is rarely caused by one thing. Energy prices feed into food production and shipping; rent moves with housing supply and interest rates; and grocery prices respond to supply shocks, weather, and demand patterns. Basket Index does not claim causality — it tracks the prices households actually face, and lets you see which categories are pulling the basket up.
