What does the Purchasing Power Parity Calculator do?

It estimates an implied exchange rate based on the prices of a comparable good or basket in two countries. You input the domestic price (in $), the foreign price, and the actual exchange rate to see the PPP rate and how it compares.

How is the implied exchange rate calculated?

The implied exchange rate is calculated as the ratio of the domestic price to the foreign price. For example, if a good costs $10 domestically and 8 units of foreign currency, the implied rate is 1.25 (domestic per foreign).

What does comparing the PPP rate to the actual exchange rate tell me?

It indicates whether a currency is overvalued or undervalued relative to purchasing power. If the actual rate is higher than the PPP rate, the domestic currency may be overvalued; if lower, it may be undervalued.

Use Cases

Compare cost of living between countries

Use the calculator to see how much a typical basket of goods should cost in another currency based on purchasing power, helping you understand relative living costs.

Example: If a basket costs $100 in the US and ¥10,000 in Japan, the implied rate is 0.01 $/¥.

Assess currency valuation for travel or business

Check if a currency is over or undervalued compared to the actual exchange rate, which can inform decisions on when to exchange money or price products internationally.

Example: If the actual rate is 0.012 $/¥ but PPP implies 0.01, the yen may be overvalued.

Tips & Common Mistakes

Tips

Use prices for the same good or basket in both countries to get a meaningful PPP estimate.
Ensure the foreign price is in the local currency of that country, not converted to dollars.
Compare the implied rate to the actual exchange rate to see if the currency is over or undervalued.
Remember that PPP is a theoretical concept; actual exchange rates are influenced by many factors.

Common Mistakes to Avoid

Using prices for different goods or services in each country, which skews the PPP estimate.
Entering the foreign price already converted to dollars instead of the local currency.
Confusing the direction of the exchange rate (e.g., domestic per foreign vs. foreign per domestic).
