There are so many variables to try to narrow it down. Depends on your rate, what you are interested in doing, college degrees, your qualifications on the ship/sub, time in service, location in United States, hourly/overtime available, etc.
Starting salary for minimum service (6 years, basic quals) could get you a job starting at $40k/yr.
Retire, EOOW, EWS, college could start at $70k/yr.
Within a few years of starting, add $20k/yr to each of them.
