How this service works
US inflation calculator from official CPI-U: what an amount of dollars in one year (or month) is worth in another, from 1913 to now, with cumulative and average annual inflation.
Output
Returns the inflation-adjusted equivalent dollar amount for the target year/month, the cumulative inflation percentage over the period, and the average annual inflation rate, all derived from official BLS CPI-U index data covering 1913 to the present.
Example use cases
Salary comparison across decades
“My grandfather earned $8,000 a year in 1965 — how much would that be worth in 2024 dollars? Show me the cumulative inflation and the average annual rate.”
Historical price context for journalism
“I'm writing about housing costs — can you tell me what $25,000 in 1975 is equivalent to in today's money, using official CPI-U figures?”
Month-level inflation between two dates
“What is $1,500 from March 2020 worth in September 2023 dollars? I want the exact CPI-based conversion including cumulative and annual average inflation.”

Endpoint
GEThttps://agents.citiviewgroup.com/v1/inflation/calculator?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative US CPI-U-based inflation adjustment for any year or month from 1913 onward, especially when you need both cumulative and average annual rates in a single call. Prefer it over generic search or LLM-estimated inflation figures when precision and official sourcing matter.
Side effects
- 'from' year earlier than 1913 — data does not exist before that date
- Invalid date format for 'from' or 'to' — must be YYYY or YYYY-MM
- Target year/month in the future beyond available CPI data — returns error or partial result
- Missing required 'from' parameter — returns 400-level error
- Non-numeric 'amount' value — schema validation failure
