Inflation Calculator
Estimate how inflation changes future prices and the purchasing power of today’s money. The result updates as you type so you can compare scenarios quickly.
Keep in mind
What it leaves out
- Real inflation variesPrices don't rise at one steady rate, and your own costs may differ.
- Pay rises and returnsWage growth and savings interest aren't taken into account.
- Different goodsSome things, like housing or energy, can rise far faster than average.
Use the calculator to compare scenarios rather than as a guaranteed forecast.
About the Inflation Calculator
Translate a sum of money today into a future price or compare how much the same nominal amount may buy later. It is useful when reviewing a savings target, a budget for future expenses or the real value of a long-term investment outcome.
How it works and an example to tryShow less
How to use the result
An assumed annual inflation rate compounds for the selected number of years. The calculator shows the higher future price of an item and the reduced purchasing power of a fixed amount of money. Actual inflation varies across years and product categories; this is a scenario based on a single rate, not an official forecast.
Example to try
If something costs 1,000 now, project the cost after ten years at 3% inflation. Compare the resulting future price with a savings goal of exactly 1,000. The exercise shows why a cash target can be met in money while falling short in purchasing power.

Who uses it, and when
Anyone setting a long-term savings target, retirees judging whether a fixed income will keep pace, and business owners deciding whether prices and wages need to rise.
Mistakes worth avoiding
- Using a single average rate when housing, energy and food rise at very different speeds.
- Treating an official annual figure as a forecast for the next ten years.
- Measuring a savings goal in today's money or dollars and being surprised it buys less later.
