About this tool
How much purchasing power has your money lost (or gained) between two points in time? This calculator uses US CPI-U (Consumer Price Index for All Urban Consumers, the standard measure published by the BLS) to convert dollar amounts between years from 1913 (the earliest year of the BLS CPI series) to 2025. Useful for retirement planning ("what will today's $50k feel like in 30 years?"), historical context ("how rich was a $5k salary in 1980?"), and salary negotiations ("am I keeping up with inflation?"). Note: CPI averages out across many goods and services — your personal inflation depends on what you buy.
What this calculator does
Converts a dollar amount between any two years from 1975 to 2025 using the US Bureau of Labor Statistics CPI-U (Consumer Price Index for All Urban Consumers) annual averages. Returns the equivalent dollar value, total cumulative inflation, and the average annualized inflation rate over the period, plus a reverse calculation (what the destination-year amount is worth in source-year dollars).
How it works — the formula
Adjusted amount = original × (CPI_to / CPI_from)
Total inflation % = ((CPI_to / CPI_from) − 1) × 100
Annualized rate % = ((CPI_to / CPI_from)^(1/years) − 1) × 100CPI-U is a Laspeyres-style price index — the cost of a fixed basket of consumer goods at different points in time. Dividing one year's CPI by another gives a price multiplier; the geometric-mean form (^(1/years)) annualizes the cumulative change into a single equivalent annual rate. Annual averages are used rather than monthly figures so the result is robust to within-year volatility (e.g. energy spikes).
Worked examples
- Inputs:
- amount = $1,000, from = 2000, to = 2025
- Output:
- CPI 2000 = 172.2, CPI 2025 ≈ 322.0; 1000 × 322.0/172.2 ≈ $1,870. Total inflation 87.0%; annualized ≈ 2.53%/yr over 25 years.
Tracks the long-term US average — slightly below 3% because the 2000s included a low-inflation decade before the 2021-2023 spike.
- Inputs:
- amount = $50,000, from = 1985, to = 2025
- Output:
- CPI 1985 = 107.6, CPI 2025 ≈ 322.0; 50,000 × 322.0/107.6 ≈ $149,628. Total inflation 199%; annualized ≈ 2.78%/yr.
A 1985 mid-career salary equates to ~$150k in 2025 dollars — useful framing for historical pay benchmarks.
- Inputs:
- amount = $100,000, from = 2025, to = 1980 (or read the reverse-row)
- Output:
- CPI 1980 = 82.4, CPI 2025 ≈ 322.0; 100,000 × 82.4/322.0 ≈ $25,590 in 1980 dollars.
The 1980 equivalent of today's $100k household income shows the magnitude of price-level change over 45 years.
When to use this vs other tools
Inflation context shows up in many planning decisions. Pair this tool with the ones below for the full picture.
- Retirement Calculator
You want to project savings and adjust target spending for inflation over a multi-decade horizon.
- Savings Goal Calculator
You are saving toward a fixed future cost (college, house deposit) and need to size the goal in tomorrow's dollars.
- Compound Interest Calculator
You want to compare nominal investment returns against the inflation rate to see real (inflation-adjusted) growth.
- Currency Converter
You are comparing inflation-adjusted amounts across currencies — convert first, then adjust each leg separately by its country's CPI.
Authority note
CPI-U is the official US consumer-inflation measure published monthly by BLS since 1913. It is the index used by the Social Security Administration for cost-of-living adjustments and by the IRS for indexing tax brackets and contribution limits. The Federal Reserve targets PCE inflation (not CPI) at 2% per its 2012 framework reaffirmed in 2024.
Limitations
- CPI averages a broad consumer basket. Personal inflation depends on what you actually buy — housing, healthcare, and college tuition have outpaced general CPI for decades. If most of your spending is in those categories, your real inflation rate is 1-3 percentage points higher than the calculator returns.
- 2024 and 2025 figures are partial-year estimates derived from monthly BLS releases; revise once BLS publishes the full annual average (typically February of the following year).
- The Laspeyres-basket methodology systematically over-estimates cost-of-living changes versus a true substitution-aware index (Boskin Commission 1996 estimated ~1.1 percentage points/year of overstatement; modern revisions have narrowed this gap but not closed it).
- Pre-1975 data is not included in this tool. For 1913-1974 conversions, see the BLS CPI Inflation Calculator directly.
- Geographic variation is significant — the same dollar amount inflates differently in San Francisco vs Cleveland. CPI-U is a national-urban-population average; regional CPIs (CPI-W, CPI-U for specific MSAs) exist for finer-grained analysis.
Inflation conversions are estimates based on a national price index. This calculator does not provide financial, tax, or investment advice. Consult a financial advisor or accountant for decisions where the precise inflation measure matters (lifetime-income calculations, indexed-benefit appeals, divorce settlements involving deferred amounts).
