Your Dollar Buys 20% Less Than in 2020 — Track Your Real Purchasing Power
Did our AI summary help? Let us know.
Cumulative inflation since 2020 means your dollar buys roughly 20% less today. From groceries to housing, understanding how inflation erodes your purchasing power helps you make better savings and investment decisions.
Ready to run the numbers?
Why: Inflation silently erodes your purchasing power every year. Since 2020, cumulative CPI has risen ~23%, meaning your dollar buys roughly 20% less. Most people underestimate this impact on savings, salaries, and retirement. This calculator quantifies exactly how much your money has lost value—and what you need today to maintain the same standard of living.
How: The calculator uses BLS historical CPI data to compound inflation year-over-year. You enter an original amount and date range; it applies category-specific or overall inflation rates, calculates the inflation-adjusted value needed today, and optionally analyzes salary shortfalls and savings erosion. Real wage and real return calculations show whether your income and investments have kept pace.

📚 Understanding Inflation & Purchasing Power
February 2026 Inflation Outlook
US CPI inflation is running at 3.2% annually as of January 2026, down from 2024 highs but still above the Federal Reserve's 2% target. Tariff-related price increases may push inflation higher in coming months.
What is Purchasing Power?
Purchasing power represents the quantity of goods or services that a unit of currency can buy. As prices rise (inflation), the same amount of money buys fewer goods - your purchasing power decreases.
Example: If you had $100 in 2020 and inflation averaged 4% annually, by 2026 you'd need approximately $126 to buy the same basket of goods. Your $100 now only has the purchasing power of ~$79 in 2020 dollars.

| 2020 | 1.2% | $100.00 |
| 2021 | 4.7% | $95.51 |
| 2022 | 8.0% | $88.44 |
| 2023 | 4.1% | $84.96 |
| 2024 | 3.4% | $82.17 |
| 2025 | 3.0% | $79.78 |

❓ Frequently Asked Questions
What causes inflation?
Inflation can be caused by increased money supply, rising production costs (cost-push), strong consumer demand (demand-pull), supply chain disruptions, or imported price increases.
Is some inflation good?
Moderate inflation (2%) is generally considered healthy as it encourages spending and investment. Deflation (falling prices) can be worse as it causes consumers to delay purchases.
How does the Fed fight inflation?
The Federal Reserve raises interest rates to slow borrowing and spending, reduces the money supply, and uses forward guidance to manage expectations. Higher rates make saving more attractive.
Should I ask for a raise?
If your salary hasn't kept pace with inflation, your real purchasing power has declined. With cumulative inflation of ~24% since 2020, a raise of at least that amount is needed just to maintain your standard of living.

📊 Inflation by the Numbers
What Is Inflation and Purchasing Power?
Inflation measures how the prices of goods and services increase over time, reducing the purchasing power of your money. When inflation is 3%, your $100 only buys what $97 would have bought a year ago. The US experienced historically high inflation in 2021-2023, with cumulative CPI increases of over 20% from 2020 to 2026.
Consumer Price Index (CPI)
The CPI measures average price changes for a basket of goods and services. It's the primary measure of US inflation.
Recent CPI:
- 2022: 8.0% (40-year high)
- 2023: 4.1%
- 2024-25: ~3%
Purchasing Power Erosion
As prices rise, each dollar buys less. $100 from 2020 now has the purchasing power of roughly $80.
Impact:
- Savings lose real value
- Fixed incomes decline
- Real wages may fall
Category Differences
Different categories inflate at different rates. Housing and food often exceed overall CPI.
2024-25 Rates:
- Housing: ~5.8%
- Food: ~4.2%
- Healthcare: ~3.8%
How Does This Calculator Work?
This calculator uses actual historical CPI data from the Bureau of Labor Statistics to compound inflation year-over-year. You can analyze overall inflation or specific categories like food, housing, and healthcare that may have affected your budget differently.

When to Use This Calculator
Understanding inflation's impact is crucial for salary negotiations, retirement planning, investment decisions, and budgeting. This calculator helps you quantify exactly how much more you need to maintain your standard of living.
Salary Negotiations
Know exactly what raise you need to maintain purchasing power. A 3% raise during 4% inflation is actually a pay cut.
