🇺🇸 United States Inflation Calculator
Calculate how inflation affects USD purchasing power. Live US inflation data from World Bank.
How Inflation Is Measured in the United States
- The US primarily uses the Consumer Price Index for All Urban Consumers (CPI-U), published monthly by the Bureau of Labor Statistics (BLS).
- Major CPI-U categories: Housing (~33%), Transportation (~15%), Food (~14%), Medical Care (~7%), Education and Communication (~7%), Recreation (~6%).
- Housing — specifically "Owners' Equivalent Rent" (OER) — is the single largest component of the US CPI basket.
- The Federal Reserve uses PCE (Personal Consumption Expenditures) inflation — not CPI — as its primary policy benchmark for setting interest rates.
- The Fed's inflation target is 2% per year using the PCE measure.
- CPI and PCE often differ slightly; CPI tends to run approximately 0.3–0.5 percentage points higher than PCE historically due to different basket methodologies and weighting approaches.

| 2019 | ~1.8% | Slightly below Fed target |
| 2018 | ~2.4% | Near Fed target |
| 2015 | ~0.1% | Oil price crash suppressed inflation |

Purchasing Power Examples
- $10,000 in 1990 would need approximately $23,300 in 2023 to have the same purchasing power, based on annual-average CPI-U (about 2.6% a year over 33 years).
- At 3% inflation, $10,000 today becomes the equivalent of about $7,441 in real purchasing power after 10 years.
- At the Fed's 2% target, prices double roughly every 36 years (Rule of 72: 72 ÷ 2 = 36).
How to Use This Calculator
- Enter a starting amount in US dollars, plus any monthly contribution you plan to add.
- Click Live Rate to load the latest annual US CPI inflation figure from the World Bank, or type your own assumption (for example, the Fed's 2% target).
- Set the interest rate to whatever the money is actually earning: a high-yield savings account, a CD, Treasury bills, or a long-run expected return for a stock or bond fund.
- Compare Nominal Value (the dollar figure on your future statement) with Real Value (what that figure will buy in today's prices).
Some common questions this page can help answer:
- Is my savings account keeping up? Enter your APY and the current inflation rate. If the effective real rate is negative, your balance grows on paper but buys less each year.
- Did my raise beat inflation? Set the interest rate to 0%, the amount to your old salary, and the time to 1 year to see what your old pay is worth in real terms, then compare it with your new salary.
- What will a fixed pension or annuity be worth later? Set the interest rate to 0% and the time horizon to your retirement length to see how a fixed payment loses purchasing power.
- How much do I need in the future to match today's money? Use the Rule of 72 readout: at 3% inflation, you need roughly twice today's amount in about 24 years.
- How large is the CPI vs PCE gap? Run the same scenario at your CPI assumption and again at roughly 0.3–0.5 points lower to see how much the choice of inflation measure changes the result.

Frequently Asked Questions
What is the US inflation rate right now?
Click the Live Rate button above to fetch the most recent available data from the World Bank. Note that World Bank data is typically 1–2 years delayed. For the current monthly BLS CPI-U figure, visit bls.gov/cpi. The Federal Reserve's preferred PCE measure is available at federalreserve.gov.
Why did US inflation spike in 2021–2022?
The 2021–2022 inflation surge resulted from a combination of factors: COVID-related supply chain disruptions reduced the supply of goods at the same time that massive fiscal stimulus (stimulus checks, enhanced unemployment benefits) boosted consumer demand. Energy prices spiked sharply, particularly after Russia's invasion of Ukraine in February 2022. Used car prices, shelter costs, and food prices all contributed significantly to the elevated CPI readings. The Federal Reserve responded with an aggressive series of interest rate increases beginning in March 2022.
What is the difference between CPI and PCE?
The CPI (Consumer Price Index), published by the BLS, measures price changes for a fixed basket of goods typically purchased by urban consumers. The PCE (Personal Consumption Expenditures) deflator, published by the Bureau of Economic Analysis, has a broader scope and allows for substitution effects (consumers switching to cheaper alternatives). The Fed targets PCE at 2%, which historically runs about 0.3–0.5 percentage points below CPI. This calculator uses World Bank CPI data, which aligns with the BLS methodology.
