Quick Overview
BLS publishes separate CPI measures for shelter, rent of primary residence, owners' equivalent rent, and household furnishings and operations. Selecting a series starts with the cost question. A broad index can frame a review, but it cannot explain one invoice.
Portfolio application
Pair the maintenance cost variance method with the series name, release month, geography, and expense category. Keep quotes, approvals, invoices, and completion records as operating evidence.
Common Mistakes
Do not use rent CPI to explain a plumbing invoice. Do not use household operations CPI as a direct forecast for a local contractor's price.
Method and limits
The BLS rent and rental equivalence factsheet defines rent and shelter scope and points to the relevant series.
Common Questions Answered
