Just finished with the Trophy Calculator

http://tranquillityguild.com/trophy/

Basically you enter in your current level as well as current experience within that level. Enter in the amount of each trophy you have and check the drop down box for how many turn ins you have in your quest log. You can select up to 10 turn ins to calculate the first ten double bonus amounts. If you simply enter in say "100", the first 50 trophies or first 10 turn ins will be doubled and the remaining 50 trophies will automatically be halved to their normal amounts. If you select "1" from the drop down menu, then 9 turn ins will be doubled and 11 will be normal, etc.

The right side of the slash indicates how much experience is remaining for the current trophy level range... it's calculated by total amount of the five levels less your current level and current experience. The left side of the slash indicates how much experience is gained from your trophy turn ins. It turns green when you are over the range amount.

That's it.

Enjoy.

The trophy and their exp amounts were pulled between Wikia and the thread located here on the forums. If you suspect the experience to be wrong, let me know and I'll see about correcting it.
