How Inflation Works and How to Protect Your Money (2026)
March 2026 · 8 min read
Quick Answer
Inflation is the rate at which prices rise over time. At 3% annual inflation, $100 today will only buy $74 worth of goods in 10 years. The best protection is investing in assets that outpace inflation: stocks, real estate and TIPS.
How Inflation Erodes Purchasing Power Over Time
At 3% annual inflation here is what $100 today is worth in real purchasing power in future years.
| Year | Real Value of $100 | Purchasing Power Lost |
|---|---|---|
| Today | $100.00 | 0% |
| 5 years | $86.26 | -13.7% |
| 10 years | $74.41 | -25.6% |
| 20 years | $55.37 | -44.6% |
| 30 years | $41.20 | -58.8% |
| 40 years | $30.66 | -69.3% |
5 Ways to Protect Your Money from Inflation
- →Invest in stocks — the S&P 500 has historically returned 7% real (after inflation) per year
- →Buy I-bonds — US government bonds that adjust with inflation, currently paying competitive rates
- →Consider TIPS — Treasury Inflation-Protected Securities adjust with CPI
- →Invest in real estate — property values and rents typically rise with inflation
- →Avoid holding too much cash long term — inflation silently erodes cash purchasing power
Inflation and Your Retirement
Inflation is retirement's silent killer. At 3% inflation your purchasing power halves every 24 years. A retiree spending $5,000 per month at 65 needs $7,000 per month to maintain the same lifestyle at 80. This is why financial planners recommend keeping a significant portion of retirement assets in growth investments like stocks even in retirement.

What is a normal inflation rate?
The Federal Reserve targets 2% annual inflation as healthy. The US averaged about 3% inflation from 1913 to 2023. Inflation above 5% is considered high and erodes purchasing power rapidly.
How does inflation affect savings accounts?
If your savings account earns 2% and inflation is 3% your money is actually losing 1% of purchasing power per year in real terms. High-yield savings accounts at 4-5% APY protect against moderate inflation.
What investments beat inflation?
Historically US stocks have returned 7-10% per year nominally which beats inflation by 4-7% real return. Real estate, TIPS (Treasury Inflation-Protected Securities) and I-bonds also provide inflation protection.
How does inflation affect mortgages?
Inflation benefits borrowers with fixed-rate mortgages. You repay the loan with future dollars that are worth less than today's dollars. Your fixed payment becomes relatively cheaper over time as wages and prices rise.
What is hyperinflation?
Hyperinflation is inflation above 50% per month. Historical examples include Germany in 1923 and Zimbabwe in 2008. It destroys the value of cash and savings and destabilises the entire economy.
