See how inflation can raise future costs and reduce purchasing power, then compare how investing may help preserve real value. You can model multiple expense lines side by side.

Future cost vs real invested value
Future cost (inflated)Real invested value
How it works
How to use
- Enter today’s cost (or budget line), expected inflation, and years ahead.
- Add an expected investment return to compare future nominal cost with real value if you invested instead of holding cash.
- Enable multi-item mode to line up several expenses (rent, groceries, etc.) with the same assumptions.
How it works
Future cost grows the amount by the inflation rate each year. "Purchasing power (cash held)" shows what your original sum would be worth in today’s purchasing power if it did not earn a return—prices rose, so each unit of currency buys less. If you enter an investment return, "Real value if invested" deflates the investment’s nominal balance by inflation so you can compare buying power, not just account balance.
