What Is the PPP Calculator?
Purchasing Power Parity is an economic theory that compares the relative value of currencies based on the price of a basket of goods in different countries. Our PPP Calculator helps you understand how far your money goes in different countries.
PPP is useful for comparing salaries and living standards across countries, planning international moves, and understanding currency valuation. The PPP rate may differ significantly from the market exchange rate.
Expatriates, international job seekers, travelers, and anyone considering moving to a different country will benefit from PPP analysis for financial planning.

The PPP exchange rate between two currencies is the ratio of the cost of an identical basket of goods in each country.
Frequently Asked Questions
Market rates are influenced by capital flows, interest rates, speculation, and trade balances, not just the relative cost of goods and services.
Multinational companies use PPP to ensure employees have similar purchasing power regardless of location. Cost-of-living adjustments are often based on PPP data.
Yes, The Economist Big Mac Index is a simplified PPP measure using the price of a Big Mac across countries.
Calculate what salary in the new country provides equivalent purchasing power to your current salary. If your Indian salary of INR 30,00,000 has a PPP-equivalent of GBP 96,000 in London, but the offer is only GBP 80,000, you would effectively take a pay cut.
PPP includes both tradable goods (electronics, cars) and non-tradable services (housing, haircuts). Non-tradable services tend to be cheaper in developing countries, which is why PPP often shows that a dollar goes further in India than the market exchange rate suggests.
If your Indian salary of INR 30,00,000 has a PPP-equivalent of GBP 96,000 in London but the job offer is only GBP 80,000, you would effectively take a pay cut. Use PPP to ensure your international job offer maintains or improves your purchasing power compared to your current lifestyle.
The Economist's Big Mac Index uses the price of a McDonald's Big Mac across countries as a simplified PPP measure. In India, a Big Mac costs approximately INR 220, while in the US it costs about $5.69. This suggests the rupee is undervalued against the dollar compared to the market exchange rate.
According to PPP calculations, the Indian rupee is consistently among the most undervalued major currencies. A dollar should buy fewer rupees based on relative prices of goods and services than the market rate suggests, meaning India offers significantly lower costs for comparable goods and services.
MNCs use PPP data from sources like Mercer and ECA International to calculate cost-of-living allowances for employees on international assignments. An Indian employee sent to Singapore may receive a 30-50% cost-of-living allowance because Singapore's PPP-adjusted prices are significantly higher than India's.
Market exchange rates determine how much currency you get for your money today, while PPP tells you whether that money buys more or fewer goods abroad than at home. If the rupee is undervalued by PPP, your money goes further in India than in countries with overvalued currencies.
Key Takeaways
PPP compares real purchasing power of currencies based on goods prices.
PPP rates often differ significantly from market exchange rates.
PPP is useful for comparing living standards and salaries across countries.
A currency can be overvalued or undervalued relative to its PPP rate.
PPP analysis helps make informed decisions about international moves.
Why This Matters
