If referring to Google Play currency fees, Google does not charge any fees for any currency payment method. However, your bank may impose fees for foreign transactions, such as a purchase conversion from Indian rupees to U.S. dollars. If referring to charging currency payments, Google will, if possible, use your home country's currency as per the home address on your Google account. If Google can't charge you in your home country's currency, it will use a different one. If you live outside of the United States, you will likely get charged in U.S. dollars. However, before your transaction gets completed, you get a chance to see the currency Google will use. Additionally, the currency you get charged in can change according to the Google service you use to make a purchase. Therefore, it may not always be in your home country's currency, and your bank may add currency fees.
