As of August 2021, the Basket Index for a US family of 4 sits at 106.6 — meaning the cost of a standard household basket has risen 6.8% versus a year ago and is up 0.46% from the previous month.
Most of the move comes from gasoline (regular unleaded), electricity (residential), rent of primary residence and ground beef (100% beef). Together these items account for roughly 81% of the year-over-year basket cost change.
Offsetting the increases: chicken (whole, fresh) (-8.5%), bread (white loaf) (-1.9%) 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.
Year-over-year change for each item, ranked by contribution to the basket move.
