How's this plan?
DW and I are 32. We wish to RE at 50. I will be fortunate enough to have a pension of $120,000 when I reach 55. My plan is to fund age 50-60 with taxable brokerage account (and the pension when it kicks in at 55). Then, fund 60-death with retirement accounts and pension.
We are both working VERY hard and staying VERY frugal as we advance in our careers. I'd like to be able to budget $200,000/year in retirement. We would probably never spend that much, but it would be nice to know that amount is available for travels and hobbies.
Here's where we are so far...
Retirement accounts: $300K
We are putting ~40K away every year. As we advance in careers, we plan to put even more away towards our goal.
