In summary:
When does your 30k pension kick in? Will it have cost of living adjustments?
For example, I can take mine after age 50 and 20 years of service, but the amount is decreased
3% for every year I am under 65. Mine will not have a COLA.
Figure out your SS if you take it at 62 or 66. Since you anticipate a long life, you might prefer taking
it later for a greater overall amount (if you live to about 78).
How much will health insurance cost from now until 65? (I use my COBRA amount for an estimate.)
And of course, mostly importantly, what are your real expenses?
I suspect you can retire now, but it would take you very little time to figure out the pension, social security, and insurance numbers. If you know your real expenses, you'll have your answer. If not, you may want to track those a few months.
