Quick Answer
Purchasing power parity (PPP) compares how much money buys in different countries by adjusting for local prices. It helps travelers, investors, and governments fairly compare costs across borders—even when exchange rates don’t reflect real value.
Key Takeaways
- Always check if a price includes VAT or local taxes before comparing
- Use online PPP calculators like those from OECD or IMF for quick estimates
- Remember: a strong currency doesn’t always mean higher living standards
- Helping families decide where to live abroad based on realistic affordability
- Setting fair international business compensation packages
