Common questions
How is the inflation calculator different from the CPI calculator?
The CPI (Consumer Price Index) is the official government measure of inflation based on a basket of goods. Our calculator lets you input any inflation rate assumption. For historical conversions, use your country's published CPI data (India: MOSPI, US: Bureau of Labor Statistics). For future projections, use your assumed rate. The formula is identical — only the input changes.
Why does the same salary feel like less money over time?
Nominal salary increases sound impressive but real purchasing power may not increase proportionally. If your salary grew from ₹5 lakh in 2010 to ₹12 lakh in 2024, that's 140% nominal growth. But at 6% inflation over 14 years, ₹5 lakh in 2010 = ₹11.3 lakh in 2024. Your "real" salary increase is only ₹0.7 lakh — not the ₹7 lakh it appears.
What is "real" vs "nominal"?
Nominal is the face value — the number on the price tag or your bank statement. Real adjusts for inflation — it measures actual purchasing power. "Real GDP growth" of 6% means the economy produced 6% more goods and services, not just 6% more money. "Real wage growth" means you can actually afford more, not just earn more rupees. Always think in real terms when comparing across time.
How do I find actual historical inflation data for India?
MOSPI (Ministry of Statistics, India) publishes monthly CPI data. The World Bank maintains free historical CPI data for all countries. RBI's annual report includes detailed inflation analysis. For the US, BLS.gov has inflation calculators with actual CPI data back to 1913. For rough estimates: India 6%, US 3%, UK 3.5%, Australia 3% as long-term averages.
Does currency exchange factor in?
Purchasing power parity (PPP) is a related but different concept — it adjusts for differences in price levels between countries rather than between time periods. This calculator handles the time-based adjustment only. For cross-country salary comparisons, see our Salary Comparison calculator which applies cost-of-living adjustments.
