How Inflation Hits Your Money (and What It Means for You)

Inflation is the slow rise in the prices of the things you buy. When inflation goes up, each dollar in your pocket buys a little less than it did before. That is the simple version, and it is also the whole story.

This is a plain-English guide to what inflation does to your money, why it happens, and what tools the government uses to track it. For a feel for how inflation eats into savings, our saving goals calculator can show what a target really costs in future dollars.

How inflation is measured

The Bureau of Labor Statistics (BLS) tracks the prices of a giant "shopping basket" of stuff a typical household buys — food, gas, rent, clothes, doctor visits, internet, and many more items. Each month it checks how much those items cost in stores all over the country.

The most famous number that comes out of this work is the Consumer Price Index (CPI). When the CPI goes up by 3% over a year, it means the basket costs about 3% more than it did a year ago. The Federal Reserve Economic Data (FRED) site lets you chart the CPI for free at fred.stlouisfed.org.

There are also other measures. Core CPI strips out food and gas because their prices jump around a lot. PCE is a different basket the Federal Reserve prefers. They usually point in the same direction.

What inflation does to a dollar

For example, if inflation runs at 3% per year for 10 years, $100 today buys what about $74 buys at the end of those 10 years. The price tag on the milk goes up. The number in your bank account stays the same. The gap is the loss in purchasing power.

This is why a savings account paying 1% in a year of 3% inflation is actually losing buying power. The dollars are still there. The dollars just buy less.

Why prices rise

The Federal Reserve and the BLS list a few common reasons:

• Demand goes up. A lot of people want the same thing at once. Sellers raise prices.
• Supply goes down. A factory shuts, a crop fails, a war disrupts shipping. Sellers raise prices.
• Costs go up. Workers get raises and energy costs more, so businesses pass it along.
• Money supply grows fast. When more dollars chase the same goods, each dollar is worth a bit less.

In real life, several of these are happening at once. The Federal Reserve's main job is to keep average inflation low and stable — its target is about 2% per year over time.

How the Fed fights inflation

The Federal Reserve (the Fed) is the U.S. central bank. When inflation is too high, it raises a short-term interest rate called the federal funds rate. That makes it more expensive for banks to borrow, which ripples out into the rates you pay on car loans, credit cards, and mortgages.

Higher rates slow down spending and borrowing, which cools off demand, which (eventually) cools off price increases. The Fed publishes its rate decisions and the reasoning behind them at federalreserve.gov.

It is a slow tool. Rate changes can take a year or more to fully show up in inflation numbers.

What inflation means for your money

A few practical effects:

• Cash in a checking account loses real value silently. Inflation does not show up on your statement.
• Fixed-rate debt quietly gets easier to pay off. If your mortgage payment is locked at $1,500 and your paycheck slowly grows with inflation, the payment shrinks as a share of your income.
• Variable-rate debt like credit cards usually gets worse, because the rate often climbs with the Fed's rate.
• Wages sometimes keep up with inflation and sometimes do not. The BLS publishes "real" (inflation-adjusted) wage data each month.
• Investments in stocks, bonds, and real estate behave differently in different inflation environments. The SEC's investor.gov has plain-English explainers for each.

Inflation-protected savings options

A few federal options are designed to keep up with inflation:

• I bonds (Series I Savings Bonds). Sold by the U.S. Treasury through TreasuryDirect. The interest rate has two parts — a fixed rate and an inflation rate that resets every six months.
• TIPS (Treasury Inflation-Protected Securities). Treasury bonds whose principal goes up with the CPI. Also at TreasuryDirect.

These are not magic. They have rules about when you can cash out, and the inflation rate can be zero or even negative. The Treasury site walks through every detail.

Inflation in your everyday budget

You can see inflation in your own life by tracking a small basket of regular spending — coffee, gas, your favorite grocery items, your phone bill. Compare what you paid last year to what you pay now. The Consumer Financial Protection Bureau (CFPB) and MyMoney.gov both have free budget templates you can use.

When inflation is high, common moves people make include:

• Trimming subscriptions you no longer use.
• Switching to store brands on the basics.
• Refilling the emergency fund first if rates have made debt more expensive.
• Asking for a raise that at least matches the published CPI for your area.

A note on advice

This is general information, not advice. Inflation hits different households in different ways — a renter in a hot housing market is hit very differently from a homeowner with a fixed-rate mortgage. A fee-only financial planner or a HUD-certified counselor can walk through your real numbers.

Numbers and rules in this article change every year — always check the latest from the SEC's investor.gov, the IRS, and your bank or broker.
