What Is Inflation, and Why Does It Matter for Your Money?

You’ve probably noticed that groceries, rent, gas and many other everyday costs are higher than they were a few years ago. That’s inflation, and it affects nearly every part of your financial life, from the value of your paycheck to the interest rates you pay and earn. Understanding how inflation works can help you protect your money and plan more confidently.

What inflation is

Inflation is the general rise in prices across the economy over time. It doesn’t mean every price goes up at the same rate. Some prices may rise sharply, others slowly, and some may even fall. Inflation refers to the overall average trend.

When inflation is 3%, something that cost $100 a year ago costs about $103 today, on average. As prices rise, each dollar buys a little less than before. Economists call this a decline in purchasing power.

A small, steady amount of inflation is generally considered normal and even healthy for an economy. Problems arise when inflation runs too high, eroding savings and making it hard for households and businesses to plan, or when prices fall broadly, known as deflation, which can discourage spending and investment.

What causes inflation

Economists describe several main causes, which often work together.

Demand-pull inflation happens when people, businesses and governments want to buy more goods and services than the economy can produce. With more demand chasing a limited supply, prices rise. This can happen when the economy is growing quickly, when consumers have extra money to spend or when borrowing is cheap.

Cost-push inflation happens when the costs of producing goods and services rise, and businesses pass those higher costs on to customers. Rising energy prices, higher wages, supply chain disruptions and more expensive raw materials can all contribute.

Expectations also play an important role. If people and businesses expect prices to keep rising, they may behave in ways that push prices higher. Workers may ask for bigger raises, businesses may raise prices in anticipation of higher costs and consumers may buy sooner rather than later. This is why central banks pay close attention to inflation expectations.

How inflation is measured

In the United States, two main measures of inflation are widely followed. The Consumer Price Index, published monthly by the Bureau of Labor Statistics, tracks the prices urban consumers pay for a basket of goods and services. It’s the measure most often cited in news reports.

The Personal Consumption Expenditures price index, published by the Bureau of Economic Analysis, covers a broader range of spending. The Federal Reserve targets 2% inflation over the longer run, measured by the PCE price index.

Why inflation matters to you

Your paycheck may buy less if your wages don’t keep pace with inflation. Even if you get a raise, your real income, meaning income adjusted for inflation, only grows if the raise exceeds the inflation rate.

Cash sitting in low-interest accounts loses purchasing power over time. If your savings earn 0.5% while inflation runs at 3%, your money effectively shrinks in real terms each year.

Borrowing costs often rise as the Federal Reserve works to bring inflation down. The Fed typically raises interest rates to slow spending and cool inflation, which makes mortgages, car loans and credit card balances more expensive.

Fixed incomes can lose purchasing power. Some pensions and annuities pay the same amount year after year, so their real value declines with inflation. Social Security benefits, by contrast, receive annual cost-of-living adjustments tied to inflation.

Inflation can affect borrowers in interesting ways too. If you have a fixed-rate loan, such as a fixed-rate mortgage, inflation means you repay it with dollars that are worth less over time.

How to protect yourself from inflation

Review your budget regularly as prices change. Inflation often hits some categories, like groceries, housing or transportation, harder than others. Adjusting your budget helps you stay on track and identify areas to cut back.

Keep emergency savings in a high-yield savings account, money market account or other insured account that pays a competitive rate. While these may not always fully keep up with inflation, they generally perform much better than traditional low-interest accounts.

Invest long-term money in a diversified portfolio. Historically, diversified investments in stocks have outpaced inflation over long periods, though they come with ups and downs along the way. Treasury Inflation-Protected Securities and Series I savings bonds are government-backed options designed to adjust for inflation.

Grow your income through raises, promotions, new skills or side income. Researching market pay for your role can help you make the case for a raise that keeps up with rising costs.

Lock in fixed rates when it makes sense. If you’re borrowing, a fixed-rate loan protects you from rising rates, while variable-rate debt becomes more expensive when rates climb.

Keep a long-term view

Inflation is a normal part of economic life, though its pace can vary dramatically over time. By understanding how it works and building habits that protect your purchasing power, you can keep your financial plans on track whatever the inflation rate happens to be.
