How It Works

How this inflation calculator works

This calculator projects future value using compound growth: Future Value = Amount × (1 + Rate ÷ 100)^Years, applying your chosen annual inflation rate every year, the same mathematical pattern as compound interest.

This uses an assumed rate, not historical CPI data

Unlike calculators that pull real historical Consumer Price Index data for a specific country, this tool uses an annual inflation rate you specify, letting you model different scenarios (for example, comparing 2% versus 5% average inflation) rather than being limited to one country's historical record.

Frequently Asked Questions

What inflation rate should I use?

A commonly used long-term average is around 2 to 3% for many developed economies, but actual inflation varies significantly by country and year. Check your country's historical average for a more tailored estimate.

Does this use real historical inflation data?

No, this calculator applies a constant rate you specify rather than pulling actual historical CPI data, making it a modeling tool rather than a historical lookup.
