How to check the paypal's current exchange rate?
I cannot speak for Paypal specifically and I doubt anyone who doesn't actually work on their internal automated payment systems could. However, I can speak from experiencing in working on automated forex transaction systems and tell you what many institutions do and it is often NOT based on live rates. There is no law stating an institution must honor a specific market exchange rate. Institutions can determine their own rates how and when they want to. However, there is some useful information on their website: https://www.paypal.com/an/cgi-bin/webscr?cmd=p/sell/mc/mc_convert-outside "The most readily available information on currency exchange rates is based on interbank exchange rates. Interbank exchange rates are established in the course of currency trading among a global network of over 1,000 banks, and are not available through consumer or retail channels." This leads me to believe they pull exchange rates from either Oanda or XE periodically and then use these rates throughout the day to conduct business. Paypal does not disclose who they use to determine rates. And it's highly doubtful they do this for every transaction (using live rates). Even if they did, there would be no way for you to check and be certain of a particular exchange rate as paypal states: " Consumers may use these rates as a reference, but should not expect to use interbank rates in transactions that involve currency conversion. To obtain actual retail rates, contact your local financial institution or currency exchange, or check the rate displayed in your PayPal transaction." This is partly because rates can change by the second just like stock prices or anything else which is susceptible to the open market's variables of supply, demand news events etc. So, even if you check the rates on Oanda (which you can do here: http://www.oanda.com/currency/converter/) you are not going to get a 100% accurate representation of what you would get by doing an exchange immediately afterwards from Paypal or any other financial institution. However, if you want to estimate, using Oanda's currency converter will likely get you close in most scenarios. That is assuming Paypal doesn't charge a premium for the exchange, which they may. That is also assuming they use live rates, it's also possible they only update their rates based on market rates periodically and not for every transaction. You may want to test this by checking the exchange rate on your transaction and comparing that to the Oanda rates at the same time.
