⚙️ How It Works
An inflation calculator shows how the purchasing power of money changes over time. It uses historical Consumer Price Index (CPI) data to calculate how much a given amount in one year is equivalent to in another year. This helps you understand the real value of money, compare historical prices, and plan for future costs.
Adjusted Amount = Original Amount × (CPI in Target Year / CPI in Base Year) | Inflation Rate = ((CPI₂ − CPI₁) / CPI₁) × 100 | Real Value = Nominal Value / (1 + Inflation Rate)^Years

❓ FAQ
What is inflation?
Inflation is the rate at which the general level of prices for goods and services rises over time, reducing purchasing power. When inflation is 3%, something that cost $100 last year costs $103 today. Central banks typically target 2% annual inflation as healthy for economic growth.
What causes inflation?
Main causes include: demand-pull inflation (too much money chasing too few goods), cost-push inflation (rising production costs passed to consumers), and built-in inflation (wage-price spiral). Excessive money supply growth is a key driver.
How does inflation affect savings?
Inflation erodes the real value of savings. If your savings account earns 1% but inflation is 3%, your purchasing power decreases by about 2% per year. This is why investing in assets that outpace inflation (stocks, real estate) is important for long-term wealth preservation.
What is the Consumer Price Index (CPI)?
The CPI measures the average change in prices paid by urban consumers for a basket of goods and services including food, housing, clothing, transportation, and medical care. It's the most widely used measure of inflation in the US, published monthly by the Bureau of Labor Statistics.
