To maintain your current standard of living in the future, you'll need to account for inflation in your financial planning. The table below shows how the purchasing power of will change over time at annual inflation.

Annual inflation rates based on Consumer Price Index (CPI) data from the U.S. Bureau of Labor Statistics.
A period of persistently high inflation rates, reaching a peak of 13.5% in 1980.
Causes: Oil price shocks, expansionary fiscal and monetary policies, wage-price spiral
A period of historically low inflation despite aggressive monetary policy.
Characteristics: Inflation consistently below the Federal Reserve's 2% target, concerns about deflationary pressures
Significant deflation during the economic contraction of the Great Depression.
Impact: Prices fell by nearly 25% over three years, worsening debt burdens and deepening the economic crisis
Sharp increase in inflation following the COVID-19 pandemic.
Causes: Supply chain disruptions, pent-up demand, fiscal stimulus, and monetary accommodation

Inflation is the rate at which the general level of prices for goods and services rises, causing purchasing power to fall over time. This economic phenomenon affects everyone from consumers to investors, businesses, and policymakers. Understanding how inflation works and its impacts is essential for making informed financial decisions.
Occurs when aggregate demand exceeds available supply.
Occurs when production costs increase, pushing up prices.
| Measure | Description | Used For |
|---|---|---|
| Consumer Price Index (CPI) | Measures changes in prices of a fixed basket of consumer goods and services | Cost-of-living adjustments, inflation targeting by central banks |
| Producer Price Index (PPI) | Measures price changes from the seller's perspective | Early indicator of consumer inflation, business planning |
| Personal Consumption Expenditures (PCE) | Measures price changes for all household spending | Federal Reserve's preferred inflation measure for policy decisions |
| GDP Deflator | Measures price changes across the entire economy | Converting nominal GDP to real GDP, measuring economy-wide inflation |
To preserve purchasing power in an inflationary environment, consider these strategies:
To estimate how quickly inflation will cut your purchasing power in half, divide 72 by the annual inflation rate. For example, at 3% inflation, purchasing power is halved in approximately 24 years (72 ÷ 3 = 24).
Calculate future value of investments with regular contributions and compound interest.
Calculate how much you need to save for retirement and see if you're on track.
Calculate growth of investments over time with compound interest.
Convert hourly wages to annual salary or annual salary to hourly rate with detailed tax calculations.

Inflation represents the rate at which the general level of prices for goods and services rises, causing purchasing power to fall over time. It's a fundamental economic concept that affects everyone—from individuals planning retirement to governments setting monetary policy. Measured as an annual percentage increase, inflation means that a dollar effectively buys less tomorrow than it does today. While moderate inflation (around 2%) is generally considered healthy for economic growth, high inflation can disrupt economies by eroding savings, complicating business planning, and potentially leading to wage-price spirals.
The causes of inflation are multifaceted and often debated among economists. Demand-pull inflation occurs when aggregate demand outpaces supply, causing prices to rise—often seen during economic booms or periods of excessive monetary expansion. Cost-push inflation happens when production costs increase, forcing businesses to raise prices to maintain profit margins. This can result from rising raw material costs, higher wages, or supply chain disruptions. Monetary inflation stems from increases in the money supply that aren't matched by economic output growth, leading to more money chasing the same amount of goods and services.
For individuals, understanding inflation is critical for financial planning. The "Rule of 72" offers a simple way to estimate how quickly inflation will halve purchasing power—dividing 72 by the annual inflation rate gives the approximate number of years. For example, at 3% inflation, purchasing power halves in about 24 years. This principle underscores why investment returns must exceed the inflation rate to generate real wealth growth. When planning for long-term goals like retirement, it's essential to factor in inflation's compounding effect, as what seems like an adequate sum today may prove insufficient decades later when prices have significantly increased.
