A $90K San Francisco offer is not the same as $40K in Bangalore. PPP normalizes for local prices so you can actually compare them.
Equivalent purchasing power

PPP is an economic measure that compares how much a basket of goods and services costs in different countries. Two salaries are at "PPP parity" when they buy the same standard of living, after adjusting for local prices. A $80,000 US salary is worth far more in Mumbai than $80,000 in Zurich, and PPP makes that visible.
When comparing job offers in different countries, evaluating remote-work salaries from foreign employers, deciding on relocation, or negotiating expat packages. Raw currency conversion misses the local cost of living; PPP corrects for it.
The PPP conversion factors used here are from the World Bank International Comparison Program (most recent published year). PPP factors update annually and reflect long-term price differences, not short-term currency fluctuations. For very recent shifts, check live exchange rates separately.
No. A currency converter uses the daily market exchange rate. A PPP calculator adjusts for what the money actually buys locally: rent, food, transport, healthcare. The two often disagree by 30 percent or more, especially between high-income and emerging markets.
PPP is based on a national basket of goods, so it averages out city-level differences (Mumbai vs rural India). It also doesn't capture quality of life factors like healthcare access, safety, or weather. Use it as one input alongside cost-of-living indexes and your own research.
