Worked example
At 3% annual inflation, today's $1,000 item would cost about $1,343.92 after ten years.

Important assumptions
This is a hypothetical scenario, not a prediction of future inflation.
How to use your results
This compares the price of the same basket over time at an assumed constant inflation rate. Cash that does not grow has lower purchasing power when inflation is positive.
Start with the example values, then replace them with amounts for the same transaction or time period. Double-check rates and units. The results are estimates intended to help you explore possible outcomes, not financial or tax advice.
Future prices and today's purchasing power
A projected future price answers what an equivalent purchase may cost after inflation. Purchasing power answers how much an unchanged pile of cash would buy at those future prices. These are two views of the same assumed rate.
Inflation differs across purchases
A nationwide inflation statistic is an average: rent, fuel, groceries and medical costs may rise at different rates. Enter a scenario relevant to your planning rather than assuming every item follows one rate.
What happens if the inflation rate is negative?
Negative inflation is deflation. With a constant negative rate, the modeled future price decreases and a fixed dollar amount gains purchasing power.
How to calculate inflation
Future price = today's price × (1 + annual inflation)^years
This compares the price of the same basket over time at an assumed constant inflation rate. Cash that does not grow has lower purchasing power when inflation is positive.
