How Inflation Affects Your Money—and What to Do About It

A $100 bill from 2000 buys roughly $57 worth of goods today. The bill didn’t change. Prices did. That’s inflation—the gradual erosion of what money can actually purchase over time.

Most of the time it moves slowly enough to ignore. Then it doesn’t. Between 2021 and 2023, US inflation reached its highest levels in four decades, peaking at 9.1% annually in June 2022 according to the Bureau of Labor Statistics. Groceries, rent, gas, and nearly everything else cost meaningfully more in a short period, and wages didn’t keep pace for most households.

This guide covers how inflation actually works, where it hits hardest, and what people with different amounts of savings can do to limit the damage.

What Inflation Is and How It’s Measured

The government tracks inflation through the Consumer Price Index—a monthly snapshot of what a representative basket of goods and services costs. The basket includes over 200 categories covering housing, food, transportation, medical care, and more. When the index rises from one year to the next, that percentage change is the inflation rate.

The CPI isn’t perfect. It measures average price changes across all consumers, which means high-rent cities and low-rent towns get averaged together. People who spend more on housing than the average feel inflation harder than the number suggests. People who own their home outright feel it less on the shelter component.

The Federal Reserve targets a 2% annual inflation rate as the long-term goal—low enough to prevent prices from spiraling but high enough to keep the economy from stagnating. Below 0% (deflation) is generally worse than moderate inflation: when prices fall, people delay purchases expecting lower prices later, which slows economic activity.

Where Inflation Hits Hardest

Rent and Housing Costs

Housing is the single largest expense for most Americans and the most visible inflation pressure point. Rent prices rose 26% between 2020 and 2023 according to Apartment List data. For renters on fixed incomes or with wages that didn’t keep pace, that increase represented a genuine reduction in what money could cover.

Homeowners with fixed-rate mortgages are partially insulated—their monthly payment doesn’t change even as rents around them rise. Property taxes and insurance do increase over time, but the core housing payment stays locked. This is one of the real financial advantages of buying rather than renting during inflationary periods.

Groceries and Everyday Purchases

Food at home rose 21% between January 2020 and January 2023. Eggs, bread, cooking oil, and dairy saw the sharpest increases. The burden falls hardest on lower-income households, where food already takes up 30–40% of the budget. A 20% grocery increase is an inconvenience for a high earner. For someone already stretched on food, it’s something else entirely. 

Fixed Incomes and Savings Accounts

Inflation is hardest on people whose income doesn’t move with prices. Social Security includes a cost-of-living adjustment each year—the 2023 COLA was 8.7%, the largest in four decades—but private pensions rarely include such adjustments. A pension that pays $2,000 per month in 2010 pays $2,000 in 2024, while the cost of living has risen roughly 40% over the same period.

Money sitting in a standard savings account loses purchasing power every year that the account’s interest rate falls below inflation. At the national average savings rate of 0.41% and inflation running at 3%, the real value of that money shrinks by about 2.6% annually—invisibly, without any dramatic event.

The Hidden Cost: What Money In a Savings Account Actually Does

The national average savings account rate is 0.41% APY according to FDIC data. If inflation runs at 3%, money in that account loses about 2.6% of its purchasing power every year. On $10,000, that’s roughly $260 per year in lost value—not lost from the balance, which stays at $10,000, but lost in what that $10,000 can buy.

Over ten years at those rates, the $10,000 balance is still $10,000—but it buys what $7,400 bought a decade earlier. The money didn’t go anywhere. The world around it got more expensive.

High-yield savings accounts at online banks currently offer 4.5–5.0% APY, which roughly matches or slightly exceeds moderate inflation. That’s not growth—it’s treading water. For money that needs to be accessible and safe, treading water beats losing ground, but it’s not a wealth-building strategy.

What You Can Actually Do

Move Idle Cash to a High-Yield Account

Money in a checking account earning near zero is losing ground. High-yield savings accounts at online banks offer 4.5–5.0% APY on savings that need to stay accessible. The difference of $20,000 between 0.41% and 5.0% is roughly $918 per year—not transformative, but it’s the easiest win available.

Consider I-Bonds for Money You Won’t Touch for a Year

Series I savings bonds pay a rate that adjusts every six months to match inflation. TreasuryDirect issues them directly from the US government with no credit risk. The catch: you can’t touch the money for 12 months, and withdrawing before five years costs three months of interest. The annual purchase limit is $10,000 per person. For money that doesn’t need to be liquid, they’re one of the few options that keep pace with inflation by design rather than by accident.

Invest Beyond Cash for Anything Long-Term

Cash and savings accounts are appropriate for money you’ll need within two or three years. For longer time horizons, the S&P 500 has returned an average of 10.5% annually since 1957—roughly 7–8% after inflation. A low-cost index fund captures that return without requiring stock-picking decisions. The risk is short-term volatility: the market drops, sometimes significantly, before it recovers. For money needed in under three years, that risk is real. For retirement savings 20 years out, short-term drops are noise in a longer trend.

Negotiate Salary Increases That Account for Inflation

A 2% raise in a 7% inflation year is a 5% pay cut in real terms—the number goes up, the purchasing power goes down. Most salary negotiations don’t account for this, which is how employees walk away feeling like they got something while actually falling behind. Asking for a raise that at minimum matches the current CPI is not an aggressive position—it’s maintaining the same standard of living.

What Inflation Doesn’t Hurt

Fixed-rate debt is one of the few things that benefits from inflation. A mortgage at 3.5% taken out in 2020 becomes a better deal every year inflation runs above that rate—you’re repaying the loan in dollars that are worth less than the dollars you borrowed. The monthly payment stays the same; the real cost of that payment declines.

Hard assets—real estate, commodities, physical goods—tend to keep pace with inflation because their prices move with it. Real estate gets cited most often as a hedge for this reason: the property value climbs, rent income follows prices upward, and a fixed-rate mortgage payment stays exactly where it was on day one. 

Bottom Line

Inflation isn’t something most people can stop, but it’s something they can position around. The immediate step for anyone with money sitting in a low-rate account is moving it somewhere it at least keeps pace—a high-yield savings account if it needs to stay accessible, or I-Bonds if it doesn’t. For longer-term money, low-cost index funds have outpaced inflation by a meaningful margin over every 20-year period on record. The choice isn’t between keeping up with inflation and not—it’s between acting on that reality now or discovering the cost of inaction later.
