It's all about investments, accounts, and expenses. So add up and analyze each of the three parts. What you'll find is how much you need to draw from investments, and how long that will last. Obviously you must manage what is going on with the household, and the investments/earnings of each spuse.
You retire, and spouse continues working for awhile. That's a plus, insofar as it means you'll draw less from the total portfolio (both spouses).
If you really don't want to do this analysis, that you can pay a professional, or go into more detail and discussion on a forum like this.
I added more numbers in post 43. While its a basic analysis, it is planned. And other then some catastrophic event , I should be ok. Right now , I think the pension alone is enough to live on. In ten years I can take some distubutions, only interest, off my investments. That will add 30k a year in passive income indefinitely. That should be good for another ten years, or more. After that , I could start taking some of the investment money itself. But, I cant see needing that much. At 70 I will be probably spending less and doing less. Plus home will be paid off halfway through that and I can always downsize at that point. Its a plan, and while we can't think of everything that comes up, it should be ok. I may need some of the money a bit earlier, if so, that shoyld be ok also. It will lower my passive income a bit. College for the kido isnt fully funded, but its started with about 30k thats invested and thats seprate from the other $$$ listed. That will be a start, and then I can use the passive income to pay some of it off a bit later. Its not perfect, but I did plan to work a bit longer.
