Inflation is the gradual increase in the general price level of goods and services over time. When inflation rises, each dollar you hold buys less than it did before. At a 3% annual inflation rate, something that costs $100 today will cost roughly $181 in 20 years — nearly double.
Understanding inflation is critical for every financial decision, from negotiating salary raises to planning retirement. If your savings and investments do not outpace inflation, you are effectively losing wealth even if your account balance grows.
Inflation in 2026: Where Things Stand
After the post-pandemic inflation surge that peaked at 9.1% in June 2022, the Consumer Price Index (CPI) has moderated significantly. As of early 2026, annual CPI inflation sits near 2.5–3.0%, closer to the Federal Reserve's 2% target but still above pre-pandemic norms.
Key price changes affecting households in 2026:
- Housing: Shelter costs remain the largest inflation driver, with rents up 3–5% year-over-year in most metro areas.
- Groceries: Food-at-home prices have stabilized but remain 25–30% above 2020 levels cumulatively.
- Healthcare: Medical costs continue rising 3–5% annually, outpacing overall inflation.
- Energy: Gas and electricity prices have normalized but remain volatile due to geopolitical factors.
- Education: College tuition continues to rise 3–4% annually, making education planning critical.
The Rule of 72 for Inflation
Just as the Rule of 72 estimates investment doubling time, it also shows how quickly inflation halves your purchasing power. Divide 72 by the inflation rate: at 3% inflation, your money loses half its purchasing power in about 24 years. At 4%, it takes only 18 years.
This means a retiree who saves $1 million today and keeps it in cash will have the purchasing power of only $500,000 in 24 years at 3% inflation. This is why simply saving cash is not enough — you must invest to outpace inflation.
Investments That Beat Inflation
Not all assets perform equally against inflation. Here are the most reliable inflation hedges:
- Stocks and index funds: Historically returning 7–10% nominally (4–7% real return after inflation). Equities are the most reliable long-term inflation hedge because companies raise prices alongside inflation.
- Treasury Inflation-Protected Securities (TIPS): Government bonds whose principal adjusts with CPI inflation. They guarantee a real return above inflation.
- I Bonds: Savings bonds with rates that adjust semi-annually based on CPI. Currently offering competitive real yields with zero risk.
- Real estate: Property values and rents tend to rise with inflation. Homeownership with a fixed-rate mortgage is an excellent inflation hedge — your payment stays constant while rents rise around you.
- High-yield savings accounts: Currently 4.0–4.5% APY, outpacing inflation. However, rates will drop if the Fed cuts further.
Inflation and Your Salary
If your salary does not grow at least as fast as inflation, you are effectively taking a pay cut every year. With 3% inflation, a $70,000 salary is worth only $67,900 in purchasing power a year later without a raise.
When negotiating raises, frame your request in real terms: "The CPI increased 3% this year, so a 3% raise maintains my current compensation. Anything above 3% is a real increase." Employers who offer only 2% annual raises in a 3% inflation environment are reducing your real compensation.
Planning for Inflation in Retirement
Inflation is one of the biggest risks retirees face. A retiree spending $50,000 per year at age 65 will need roughly $67,000 per year by age 75 and $90,000 per year by age 85 at 3% inflation — just to maintain the same lifestyle.
Social Security provides a partial hedge with its annual Cost of Living Adjustment (COLA), but COLAs often lag behind actual retiree expenses, especially healthcare. Building an investment portfolio that continues growing in retirement is essential. Our Inflation Calculator shows exactly how much your expenses will grow over any timeframe.

Frequently Asked Questions
What is the difference between CPI and real inflation?
CPI (Consumer Price Index) is the official government measure of inflation, tracking a basket of goods and services. However, your personal inflation rate may differ significantly depending on your spending patterns. If you spend heavily on healthcare and education (which inflate faster than CPI), your real inflation rate is higher than the headline number. Our calculator uses CPI as a baseline, but you can adjust the rate to match your personal situation.
Is 3% inflation considered high?
Historically, 3% is moderate. The Federal Reserve targets 2% annual inflation as optimal. The 2022–2023 period of 6–9% inflation was unusually high. Over the long term, U.S. inflation has averaged about 3.2% since 1926. At 3%, prices double roughly every 24 years — manageable if your investments grow faster.
How does inflation affect my savings account?
If your savings account earns less than the inflation rate, you are losing purchasing power. A savings account paying 0.5% APY during 3% inflation loses about 2.5% of real value per year. In 2026, high-yield savings accounts paying 4.0–4.5% APY outpace inflation, making them a good option for short-term savings. For long-term growth, stocks and index funds are necessary to reliably beat inflation.
Should I worry about deflation instead?
Deflation (falling prices) is rare and generally worse than moderate inflation for the economy. The last significant U.S. deflation was during the Great Depression. Central banks actively prevent deflation because it discourages spending, increases real debt burdens, and can trigger economic spirals. For personal planning, assume 2–3% annual inflation as your baseline.
