PPCalc is a tool made for eBay sellers which allows them to quickly and easily calculate their PayPal fees before accepting money online. It is an off-line extension to the PPCalc website (PPCalc.com), a free online PayPal fee calculator. This ''off-line'' edition has exactly the same functionality as the website but is mainly used by individuals who either don't have internet access or who just don't want to open up their web browser to calculate their PayPal fees.

It includes support for all the different PayPal fee rates (including the Standard Rate and all levels of the Merchant Rate) and it also supports all the different countries and currencies that PayPal supports. You can even choose to calculate in the 2.5% currency conversion fee that is used in some multi-currency transactions.

You can also use it to ''reverse'' calculate your PayPal fees to determine the exact amount a person must send you in order for you to get the amount you want. (For example, if you want to actually receive $75 in your PayPal account a person would have to send you $77.55).
