we paid off the house 18 months before i retired so that we could save that money. already had savings of 12 plus months to live on without any income. maxed out the 401k every year so that is huge. haven't had to touch it. the pension is enough and in a couple years we can start on the social security.
one thing you should do is get any major medical and dental out of the way before you go out. here in the west we have to pay 150 month for healthcare coverage and they only pay 70 % so your medical/dental will go up.
also make major purchases before you go out. we put in a new floor, new appliances, bought a late model car and repaired the older one, saved up for a new roof , and made some other major repairs. it's easier to do that while working making 80-100k rather than the 35-50 you'll get with your pension.
also , write out your monthly budget now while you are working. write down EVERY expense you can think of plus some amount for the unexpected. then add 10-20% on top of that just in case. some expenses go down when you retire like gas and car repairs and work related expenses. the only thing that has gone up for us is we are eating out more. and we travel more too.
this will give you an idea on what you need for monthly retirement expenses. the way we figured it we would have almost a thousand dollar surplus every month and after a year we had slightly more than that so we went crazy buying Christmas early for the grandkids and gifted the grown kids too. that was nice.
granted, we have had no emergencies pop up but we do have a separate savings account for that.
good luck.
