Capabilities

Tools 5

calculate_inflation

Adjusts a dollar amount for inflation between any two periods from 1913 to the latest month the U.S. Bureau of Labor Statistics has published, using the official CPI-U (or CPI-W or core CPI). Checks the BLS Public Data API live for months newer than its bundled data (bundled through September 2026, fetched 2026-11-03), so it knows CPI figures newer than a model's training data. Handles the October 2025 gap: BLS published no October 2025 CPI because of the 2025 lapse in appropriations. Returns the adjusted amount, cumulative and average annual inflation, and the exact index values used.

Discovered
calculate_social_security_cola

Computes the Social Security cost-of-living adjustment for a year with the statutory formula: average CPI-W for July-September of the prior year over the same quarter a year earlier, rounded to 0.1%. Uses official BLS CPI-W values (live check). Reproduces the 3.6% COLA for 2027 that SSA announced in October 2026, and shows the Q3 index values behind it. Covers 1976 onward.

Discovered
compare_raise_to_inflation

Compares a pay change with CPI inflation over the same period using official BLS data through the latest published month (checked live). Returns the nominal raise, inflation, the real (inflation-adjusted) raise, the pay needed to keep pace, and the gain or shortfall. Works for salaries, hourly wages, rents or any recurring amount.

Discovered
get_inflation_rate

Returns the official U.S. inflation rate for a calendar year from BLS CPI data: annual-average change (BLS annual averages, including the 2025 average published despite the missing October 2025 index), December-to-December change, and for the current year the latest 12-month rate. Years 1914 to the present for CPI-U and CPI-W, 1958 onward for core CPI.

Discovered
get_latest_cpi

Returns the most recent CPI index values published by the Bureau of Labor Statistics, checked live against the BLS Public Data API: the latest month, the 12-month inflation rate for headline CPI-U, CPI-W and core CPI (less food and energy), the not seasonally adjusted 1-month change, and the year-to-date change. Use it to answer 'what is inflation right now'. If the live check fails it says so and falls back to bundled BLS data (through September 2026).
