Is there a Mileage calculator APP that can figure out the various formulas the airlines use to credit mileage to your account?

It used to be that you got one mile for every mile you flew but now distance flown has very little or nothing to do with it; you have to figure out the ticket code, whether it's K V T D F or whatever, fare paid, your status in the program and if you book with a partner airline that makes it even more complicated, if you fly with a partner airline the amount of miles you earn could be 100 %, 50 % 25 % depending on the ticket code or whatever.

When you call the airlines to find out even the agents working there have a difficult time figuring it out.

I wish there was a Mileage Calculator that you could just enter all of that information and have a definitive answer.
