1. What is Purchasing Power Parity (PPP)?

Purchasing Power Parity (PPP) is an economic theory that compares different countries' currencies through a "basket of goods" approach. It states that exchange rates between currencies should equal the ratio of their price levels for a common basket of goods and services.

2. How Does the PPP Calculator Work?

The calculator uses the PPP equation:

\[ PPP = \frac{Price\ Currency\ A}{Price\ Currency\ B} \times FX\ Rate\ (A/B) \]

Where:

\( Price\ Currency\ A \) — Price of good in first currency
\( Price\ Currency\ B \) — Price of same good in second currency
\( FX\ Rate\ (A/B) \) — Exchange rate between currencies (units of A per unit of B)

Explanation: The equation calculates the relative value between currencies based on the actual purchasing power rather than just market exchange rates.

3. Importance of PPP Calculation

Details: PPP is crucial for comparing economic productivity and standards of living between countries. It's used by economists to make more accurate international comparisons of GDP and other economic indicators.

4. Using the Calculator

Tips: Enter prices for the identical good/service in both currencies and the current exchange rate. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What does a PPP value of 1 indicate?
A: A PPP of 1 indicates perfect parity - the currencies have equal purchasing power for the specific good/service being compared.

Q2: How is PPP different from market exchange rates?
A: PPP reflects actual purchasing power while market rates are influenced by speculation, interest rates, and capital flows.

Q3: What are typical goods used for PPP comparisons?
A: Common examples include the Big Mac Index (for informal comparisons) and standardized baskets of consumer goods for official statistics.

Q4: Why might PPP differ across different goods?
A: Non-tradable goods (like services) often show larger PPP deviations due to local cost differences.

Q5: How often should PPP be recalculated?
A: For accurate comparisons, PPP should be recalculated whenever prices or exchange rates change significantly.
