I put the six figure assumption right at $100,000
I assumed $40,000 which is a low-ball estimate of 50% of base pay at 20.
$100,000+$40,000=$140,000
The retirement is "factored" into that. Botton line, retire from the Navy, get a good job, contribute to your Roth and you are set. If you invest more, you are more set. Of course, don't forget taxes, and lack of taxes for the Roth, hence my disclaimer of not considering everything.
Oh, ok, I got ya, didn't catch it in the numbers.
