Questions
What is the latest San Francisco-Oakland-Hayward CPI-U change?
From August 2025 (357.992) to August 2026 (370.130), the index change is 3.391%. That is the raw change before any contractual floor or cap.
Can this series be used for any contract in California?
Only if the contract names this area, or names this series. A clause that says CPI without a geography is ambiguous. The U.S. city average is a different series.
Sources and limits
Index levels from the U.S. Bureau of Labor Statistics Consumer Price Index, not seasonally adjusted, retrieved through the BLS Public Data API on November 1, 2026. Values are index points, not the headline 12-month percent.
Statewide rates reflect U.S. Department of Labor state minimum-wage postings as updated January 1, 2026, the U.S. Department of State Diplomatic Note on 2026 increases, and, for the prior-year comparison and named local rates, the National Employment Law Project compilation published in November 2025. Confirm the rate that applies to the workplace before using it in a bill.
The contracts in these worksheets are fictional. The prices are chosen so the arithmetic is easy to check. They are not a price survey and they are not client results.
RateClause is not a law firm. Nothing on this page is legal advice. Your clause controls, including whether a past period can be rebilled at all.
