Nice site, great idea. Embark further beyond just the PayPal fees though. Make a universal fee calculator website ranging from eBay, Amazon to PayPal, ePassporte, Payza and so on. You could even implement an Earnings & Tax Calculator down the road. The more than you incorporate, the more traffic your site will generate.

Go to the Graphics Section here on WJunction and have someone design you a new banner for your website as yours is quite plain.
Looking at some of the text on your site, it isn't worded properly.
This site is not by PayPal and it not connected to PayPal company in anyway.
By using this tool, the user agree's that he will take all the responsibility. The tool may not show 100% exact result.

Should Read:
This site is not endorsed nor affiliated with PayPal in any way. Use of this service is strictly platonic as provided in PPFC User Terms.
That's it, remove everything else, nothing else is needed.

You have a "More Tools" page, which is going back to what I said of you incorporating more things. You need to actually create a site that encompasses all of these things and offer them all on the landing page as opposed to stuffing them away. The more services that you can provide people, the more returning users and new users you will generate.
All in all, good idea, nice site and I applaud you on your zero advertisements!
Good luck.
