Inflation Calculator
This inflation calculator estimates how rising prices affect future costs and purchasing power over a selected time period.
Quick answer
Future cost applies compound inflation to current amount.
What this tells you
- •Future cost applies compound inflation to current amount.
- •Purchasing power estimates what the same amount buys in future-value terms.
- •Increase amount shows nominal price change from inflation.
How to Use
- 1Enter a current amount.
- 2Enter expected annual inflation rate.
- 3Enter number of years.
- 4Calculate to compare present and future value.
How It Works
Formula
Future Cost = Amount x (1 + rate)^years
Purchasing Power = Amount / (1 + rate)^yearsInflation is modeled as annual compounding growth in prices.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
$1,000 over 10 years at 3%
Amount$1,000
Rate3%
Years10
Result$1,343.92 future cost
Common mistakes
- Entering rate as decimal instead of percent
- Using unrealistic long-term fixed inflation assumptions
- Confusing nominal and real value
Limitations
This estimate uses one constant inflation rate over the full period. Actual inflation changes over time and can differ significantly from long-term assumptions.
