This is the biggest, baddest calculator I could find. Includes just about everything and is pretty accurate as far as I can remember.

Also, I have only tested this on Firefox (what I use..) so if it doesn't work for you, DL Firefox and browse like a real man!
Also another useful link if you don't remember the exact names of your skills

There is no bookmark saving feature but you can do the printable version, select all and then put it into a word/notepad document, save it on Desktop or throw it on the forums. Whatever works for you!
Thought I would share with you guys in case you haven't found it or lost it.
Happy Building,
