Inflation measures how much prices increase over time, reducing the purchasing power of each dollar. The Federal Reserve targets 2% annual inflation — enough to encourage economic activity without eroding savings too quickly. The Bureau of Labor Statistics (BLS) tracks inflation using several measures.
How Is Inflation Measured? CPI, Core CPI, and PCE Explained
| Measure | What It Includes | Used For |
|---|---|---|
| Headline CPI | All items including food & energy | Actual cost-of-living impact |
| Core CPI | Excludes volatile food & energy | Underlying inflation trend |
| PCE | Personal Consumption Expenditures | Fed’s preferred measure |
What Are the CPI Basket Weights? (Current Categories & YoY Rates)
| Category | Weight | Includes | Jan 2026 YoY |
|---|---|---|---|
| Shelter | 36% | Rent, owners’ equivalent, utilities | +3.0% |
| Transportation | 15% | Vehicles, gas, insurance, fares | +1.1% |
| Food & Beverage | 13% | Groceries, dining out | +2.9% |
| Medical Care | 8% | Insurance, services, drugs | +3.2% |
| Recreation | 6% | Entertainment, electronics, sports | +2.5% |
| Education & Communication | 6% | Tuition, phone, internet | +1.4% |
| Energy | 7% | Gasoline, electricity, natural gas | −0.1% |
| Other | 9% | Apparel, personal care, other | — |
Why Does the Fed Target 2% Inflation, Not 0%?
Deflation (falling prices) can trigger a downward spiral — consumers delay purchases, businesses cut wages, and demand collapses. The Fed targets 2% because moderate inflation encourages spending and investment while keeping prices relatively stable. Zero inflation leaves no buffer against deflation during economic downturns.
What’s the Difference Between CPI and PCE?
Both measure price changes, but the PCE (Personal Consumption Expenditures) index — the Fed’s preferred measure — updates its basket of goods quarterly to reflect actual consumer substitution, while the CPI uses a fixed basket updated less frequently. PCE typically runs 0.2–0.5 percentage points below CPI, which is why the Fed’s 2% target feels closer to 2.3–2.5% on a headline CPI basis.
Historical Inflation Rates
US inflation rate history spans over a century — from the 23% spike during World War I to near-zero rates during the Great Recession. The tables below cover average inflation by decade, the major inflationary eras, and annual CPI rates from 2015 through 2025.
Average US Inflation Rate by Decade (1910s–2020s)
| Decade | Avg Annual CPI | Defining event |
|---|---|---|
| 1910s | 8.6% | WWI spending; sharp deflation followed in 1921 |
| 1920s | −0.3% | Post-war deflation; decade averaged slight price declines |
| 1930s | −2.0% | Great Depression; severe deflation; prices fell most years |
| 1940s | 5.6% | WWII price controls, then post-war demand surge |
| 1950s | 2.1% | Korean War bump; largely stable post-war decade |
| 1960s | 2.5% | Vietnam War spending begins building inflationary pressure |
| 1970s | 7.1% | Oil shocks, loose monetary policy; peak 13.5% in 1979 |
| 1980s | 5.6% | Volcker disinflation; rates fell from 14.8% to 3.8% |
| 1990s | 3.0% | Fed credibility established; globalization suppressed goods prices |
| 2000s | 2.6% | Stable until 2008 financial crisis; energy price spikes |
| 2010s | 1.8% | Persistently below 2% target; weak demand, falling energy |
| 2020s (partial) | 4.2% | COVID stimulus, supply chains, energy shocks; peak 9.1% in 2022 |
Decade averages use the annual average CPI-U (not December-over-December) for consistency across the full historical dataset. Source: Bureau of Labor Statistics.

| Great Inflation (1965–1982) | 14.8% | Vietnam spending, oil shocks, loose policy; ended by Volcker raising rates to 20% |
| Great Moderation (1983–2007) | 3.0% avg | Fed credibility established; globalization kept goods prices low |
| Post-Financial Crisis (2008–2020) | 1.7% avg | Consistently below 2% target; weak demand, falling energy prices |
| COVID Era (2021–2023) | 9.1% | Supply chains, fiscal stimulus, energy shocks; Fed hiked to 5.5% |
Annual Inflation Rates by Year (2015–2025)
| Year | CPI (Dec YoY) | Context |
|---|---|---|
| 2015 | 0.1% | Oil price collapse |
| 2016 | 1.3% | Below target |
| 2017 | 2.1% | At target |
| 2018 | 2.4% | Slightly above target |
| 2019 | 1.8% | Below target |
| 2020 | 1.2% | COVID recession |
| 2021 | 4.7% | Inflation surge begins |
| 2022 | 8.0% | 40-year high; Fed hikes begin |
| 2023 | 4.1% | Declining but elevated |
| 2024 | 2.9% | Continued normalization |

Recent Inflation & Fed Response
The 2021–2023 inflation surge was the most significant since the early 1980s, driven by a confluence of supply-side shocks and unprecedented fiscal stimulus. Understanding the causes of this inflation episode explains why the Fed raised rates at the fastest pace in four decades.
What Caused the 2021–2023 Inflation Surge?
| Factor | How It Drove Inflation |
|---|---|
| Supply Chain Disruptions | COVID shutdowns halted manufacturing; container shipping backed up; chip shortages hit autos and electronics |
| Fiscal Stimulus | 2020–21 stimulus totaled 4× the 2008 response (as % of GDP); M2 money supply rose 42% in 22 months |
| Energy Price Shock | Russia–Ukraine war disrupted global oil and gas markets; U.S. gas prices hit $5/gal in mid-2022 |
| Demand Shift | Spending swung from services to goods (home offices, electronics); production couldn’t keep pace |
Federal Reserve Rate Timeline (2020–2026)
| Date | Fed Funds Rate | Action |
|---|---|---|
| Mar 2020 | 0–0.25% | Emergency cut to near-zero for COVID |
| Mar 2022 | 0.25–0.50% | First rate hike; tightening cycle begins |
| Jun 2022 | 1.50–1.75% | 75 bps hike (CPI at 9.1% peak) |
| Jul 2023 | 5.25–5.50% | Peak rate — highest since 2001 |
| Sep 2024 | 4.75–5.00% | First cut (50 bps); easing cycle begins |
| Jan 2026 | 3.50–3.75% | Current rate; held steady after three 25 bps cuts in late 2025 |
Current status (January 2026): Headline CPI fell to 2.4% in January 2026 (core 2.5%) — the lowest since May 2025. Shelter (+3.0%) and medical care (+3.2%) remain the stickiest categories. The Fed held rates steady in January 2026; markets are pricing in further cuts if disinflation continues through mid-year.
Purchasing Power & Protection
Inflation erodes the purchasing power of money over time. A dollar today buys less than a dollar 10 years ago, making it essential to earn at least the rate of inflation on savings.
How Much Has Inflation Eroded the Dollar’s Purchasing Power?
| Year | $100 Then → Today | Total Inflation | Context |
|---|---|---|---|
| 1970 | $815 | +715% | Pre-Great Inflation |
| 1980 | $390 | +290% | Peak inflation era |
| 1990 | $245 | +145% | Post-Volcker stability |
| 2000 | $185 | +85% | Dot-com era |
| 2010 | $146 | +46% | Post-financial crisis |
| 2015 | $134 | +34% | Low inflation period |
| 2020 | $124 | +24% | Pre-COVID |

Rule of 72: How Long Until Prices Double at Different Inflation Rates?
Divide 72 by the annual inflation rate to estimate how many years until prices double.
| Inflation Rate | Years to Double | Example Period |
|---|---|---|
| 2% | 36 years | Fed target rate |
| 3% | 24 years | Great Moderation average |
| 5% | 14 years | Moderately elevated |
| 7% | ~10 years | Near 2022 levels |
How Do You Protect Savings from Inflation? (I Bonds, TIPS, HYSA & More)
| Strategy | How It Helps | Considerations |
|---|---|---|
| High-Yield Savings | 4–5% APY can match or beat inflation | Rates fall when Fed cuts; short-term solution |
| I Bonds | Inflation-adjusted; currently 4.03% composite | $10k/year limit; 1-year lock-up; 3-month penalty if <5 years |
| TIPS | Treasury bonds with inflation-adjusted principal | Complex tax treatment; better in tax-advantaged accounts |
| Stock Market | Historically ~10% nominal return (~7% real) | Volatile short-term; long-term horizon needed |
| Real Estate | Property values and rents tend to rise with inflation | Illiquid, high entry costs, not guaranteed |
Cash drag: At 3% inflation, $10,000 in a 0.01% checking account loses roughly $2,560 in purchasing power over 10 years. Savings need to earn at least the inflation rate to maintain their real value.
