I don't know about all those scenarios or for that matter your numbers...but do you really want to stay a freight dog? Most actually transfer to the pax fleet in year 4 so lets look at a US based freighter F/O going to pax in year 4 and a command starting year 10. Here are the actual numbers!
Year CoS99 CoS07
1 63,504 72,852
2 69,504 74,304
3 75,504 75,792
Pax
4 113,160 86,028
5 116,040 97,644
6 118,920 110,820
7 121,680 113,040
8 124,320 115,296
9 126,840 117,600
Total 929,472 863,376 (-66,096)
Cpt Pax
10 181,560 155,004
11 184,800 158,100
12 194,880 161,268
13 198,120 164,484
15 199,560 167,772
Total 958,920 806,628 (-152,292)
So a 15 year career with a year 10 promotion to Captain will gross you $218,388 more on CoS99 than CoS07!
They give you a little up front for the first 2 years but then they take away for a lifetime.
