Yeah, it's possible if I read your post correctly. You can run FIRECALC (click on the link at the opening page of this board) to see how your plan would have worked historically. I ran your numbers as I read them:
current nest egg = $650K
earn: $15K per year for next 13 years (I assumed this amount was inflation adjusted)
retire completely in 13 years (no further earnings)
I assumed no ss benefits and no pension.
I also assumed that you chose to invest your current nest egg in 50% equities/50% TIPS
I used CPI as the inflation index and assumed an expense ratio or 0.18
Historically, this kind of strategy would have supported a $36K per year lifestyle adjusted for inflation for at least 35 years.
If you use a CD and money market investment strategy, your safe withdrawal rate (SWR) would have been far less than $36K. Similarly, if your earnings for the next year are fixed at $15K rather than adjusting that upward for inflation, your SWR would be less.
Good luck with your plan.
