US Inflation Rate Over Time
The chart below shows annual US CPI inflation from 1960 to 2025. Shaded areas represent US recession periods. Notice the dramatic spike during the stagflation era of the late 1970s and early 1980s, and the post-pandemic surge in 2021–2022.
Average Inflation by Decade
Breaking inflation down by decade reveals clear patterns. The 1970s and early 1980s were marked by double-digit averages, while the 2010s saw historically low inflation near the Fed's 2% target.
The Inflation Rate Formula
The inflation rate measures the percentage change in price level between two time periods. The standard formula used by the Bureau of Labor Statistics (BLS) is:
Inflation Rate = ((CPInew − CPIold) / CPIold) × 100 Where CPInew is the Consumer Price Index in the current period and CPIold is the CPI in the base period. For example, if CPI rose from 260 to 267.8 over one year:
((267.8 − 260) / 260) × 100 = 3.0% The Fisher equation for real returns is:
Real Return = ((1 + Nominal Return) / (1 + Inflation Rate)) − 1 5 Key Insights About Inflation
The Silent Tax
At 3% annual inflation, your money loses half its purchasing power in just 24 years. A dollar in 2000 is worth only about $0.57 in 2025 dollars — a 43% erosion without a single tax being levied.
Cash Is Not Safe
Holding cash in a savings account earning 0.5% while inflation runs at 3% means you're losing 2.5% of purchasing power annually. Over a decade, that's roughly a 22% real loss on your "safe" savings.
Stocks Have Beaten Inflation
The S&P 500 has returned approximately 10% annually since 1960, well above the 3.8% average inflation rate. This ~6% real return is why equities remain the primary long-term wealth builder.
The 1970s Warning
From 1973 to 1982, cumulative inflation exceeded 130%. Investors who held long-term bonds or cash saw devastating real losses. This decade reshaped monetary policy and gave rise to inflation-indexed bonds (TIPS).
Post-Pandemic Surge
2022's 8.0% inflation was the highest since 1981, driven by supply chain disruptions, fiscal stimulus, and energy costs. The Fed's aggressive rate hikes brought it back toward target by 2024–2025, but the episode highlighted inflation's ability to return unexpectedly.
What Is Inflation?
Inflation is the rate at which the general level of prices for goods and services rises over time, eroding the purchasing power of money. When inflation increases, each unit of currency buys fewer items. Central banks, such as the Federal Reserve, aim to keep inflation at a moderate level — typically around 2% per year — to maintain economic stability.
Consumer Price Index (CPI)
The CPI is the most widely used measure of inflation. Compiled monthly by the Bureau of Labor Statistics, it tracks the average change in prices paid by urban consumers for a representative basket of goods and services including food, housing, transportation, medical care, and recreation. The CPI-U (all urban consumers) covers about 93% of the US population.
Core Inflation
Core inflation strips out volatile food and energy prices to reveal the underlying inflation trend. Because food and oil prices can swing dramatically due to supply shocks (weather, geopolitical events), core CPI gives the Federal Reserve a cleaner signal for monetary policy decisions. When you hear the Fed discussing inflation expectations, they often reference core PCE (Personal Consumption Expenditures) rather than headline CPI.
Deflation
Deflation is the opposite of inflation — a sustained decrease in the general price level. While falling prices might sound beneficial, deflation can be devastating for an economy. When consumers expect prices to drop, they delay purchases, reducing demand and corporate revenues. This can trigger layoffs, further reducing spending in a dangerous deflationary spiral. Japan's "Lost Decades" from the 1990s onward are the most cited example of prolonged deflation.
How Inflation Impacts Different Asset Classes
- Stocks: Generally outpace inflation over the long term as companies can raise prices and earnings.
- Bonds: Fixed-rate bonds lose value in high-inflation environments since their coupon payments buy less.
- Real Estate: Property values and rents tend to rise with inflation, making it a traditional inflation hedge.
- Cash & Savings: Directly eroded by inflation — the worst performing asset class in real terms during inflationary periods.
- TIPS: Treasury Inflation-Protected Securities adjust their principal based on CPI, providing direct inflation protection.
- Commodities: Often rise with inflation, especially energy and agricultural goods, since they are components of the price indices themselves.

Frequently Asked Questions
What is the current US inflation rate?
As of early 2025, the US inflation rate is approximately 2.8% year-over-year, measured by the Consumer Price Index (CPI). This is down significantly from the 2022 peak of 8.0% and is approaching the Federal Reserve's long-term target of 2%.
How is the inflation rate calculated?
The inflation rate is calculated using the formula: ((CPI_new - CPI_old) / CPI_old) × 100. The Bureau of Labor Statistics (BLS) collects prices for a basket of goods and services each month to compute the Consumer Price Index, then the percentage change between two periods gives the inflation rate.
What is the difference between CPI and core inflation?
CPI (Consumer Price Index) measures the overall change in consumer prices for a basket of goods and services including food and energy. Core inflation excludes volatile food and energy prices to show the underlying inflation trend, giving policymakers a clearer picture of long-term price pressures.
How does inflation affect my investments?
Inflation erodes purchasing power, meaning your investment returns must exceed inflation to generate real wealth. For example, a 7% nominal return with 3% inflation yields only about 3.88% in real terms. Fixed-income investments like bonds are particularly vulnerable, while equities and real assets like real estate have historically outpaced inflation over the long term.
What was the highest inflation rate in US history?
The highest annual CPI inflation rate in recent US history was 13.5% in 1980, during the oil crisis and stagflation era. The Federal Reserve under Paul Volcker raised interest rates to nearly 20% to combat this runaway inflation, triggering a recession but ultimately bringing inflation under control by the mid-1980s.
