How this calculator works
The result depends on the numbers you enter and the assumptions shown below.

Inflation compounds over time. The future cost shows what the same basket may cost later, while purchasing power shows how much today's amount would effectively buy after inflation.

Review the inputs carefully and treat the output as an estimate. For decisions involving money, taxes, health, law, or security, compare the result with trusted professional guidance when needed.

Frequently asked questions

What inflation rate should I enter?

Use a national average, a category-specific estimate, or a conservative scenario rate. For personal planning, test more than one rate because inflation can vary by category.

What inflation rate does this use?

You enter the inflation rate yourself, so the calculator can match your country, category, or planning scenario.
