Inflation Calculator
Calculate how inflation affects purchasing power and future prices
Calculate Inflation Impact
Understand how inflation erodes purchasing power over time. Enter your current price and the expected inflation rate to see what you'll need to spend in the future to buy the same item.
Formula
Future Price = Current Price × (1 + inflation rate)^years
This formula calculates compound inflation. It shows how prices increase exponentially over time at a consistent annual inflation rate. The result represents what you would need to spend in the future to purchase the same item.

- Forgetting to account for deflation: During deflationary periods, enter negative rates carefully.
- Confusing nominal vs real values: This calculator shows nominal future prices. Consider real returns separately.
- Ignoring category-specific inflation: Different goods inflate at different rates. Use appropriate rates for your use case.

Formula Explained
The inflation calculation uses the compound growth formula:
Future Price = Current Price × (1 + inflation rate)^yearsWhere the inflation rate is expressed as a decimal (e.g., 3% = 0.03). This shows how the purchasing power needed to buy the same item increases over time.
