Financial decision guide and interactive simulator

Inflation reality calculator

How has purchasing power changed between two years?

What this calculation is designed to show

Inflation comparisons use consumer price index data to translate an amount between years. CPI represents a broad basket, so personal inflation can differ when housing, food, transport or medical spending dominates a budget.

How to test the decision

Use the result to compare old and current salaries, prices or savings goals in equivalent money. Treat it as historical context rather than a forecast of the next year's inflation.

Using the result responsibly

Change one important assumption at a time and compare a cautious case with the expected case. The interactive calculator below updates from the values you enter. Its output is an educational estimate, not financial, tax, legal or investment advice.
