Congrats on your decision
Your income of $200K and savings look like a recipe to success to me
A couple of things, you said "sorry" a lot in working through questions and answers. learning exploring, clarifying and revising as part of the process are no reason to apologize. I am just saying we all came here to learn and it is part of the process. Do you want your students to apologize as they grasp something you are teaching them?
I am not questioning your expenses. Mine turned out to be a lot less that I thought.
I took my Quicken expenses the last 4 years. I then removed my Mortgage (paid off), removed 401K contributions (don't do that after retirement), removed the savings for after tax, removed the big things never do again like my daughters weddings. Removed taxes, ss and med tax.
I modified health insurance based on what I would have to pay
I then calculated state and Fed tax based on expenses.
The average over 4 years with expected taxes and Insurance was $30K less a year than I had actually been spending when I "normalized" it for retirement. I buy stuff when I want. One of our trips every year is international and we fly business class. We have cleaning people come twice a month, etc
Have you done something similar to normalize your expenses over the last few years to project future expenses? Maybe you have and with the help to a family member your expenses are still higher
With you income and investment balance you seem in good shape, but we dont know your actual situation.
Congrats on your decision and start thinking about what you will do next June.
Congrats again!
