Frequently Asked Questions
What inflation rate should I use?
Use a realistic long-term assumption or a historical average for scenario planning. Actual inflation varies by year and category.
Is this based on CPI?
The calculator uses the average annual inflation rate you enter. CPI is a common benchmark, but the tool does not fetch live CPI data.
Why is inflation compounded?
Each year's price increase applies to the prior year's already-inflated price, so the effect compounds over time.
What is purchasing power?
Purchasing power describes what a dollar amount can buy. When prices rise, the same amount of money buys less.
Can I use this for salary planning?
Yes. It can show how much income may need to rise to maintain similar purchasing power.
