Each change compares a year with the one before. Large swings usually come from a partial year, extra hours or a change of job rather than a raise. Prices: Consumer Price Index (CPI-U, U.S. city average) from the Bureau of Labor Statistics, averaged July to June; FY 2026 uses 11 months because October 2025 was not published.
