Well, some good advice on here. My situation is VERY similar. I retired from the public education sector at age 57 (just turned 63) nearly the exact same amount you will receive. After retirementI stayed in education only at the private sector that pays very little but is very rewarding. Then I got very sick at age 60 and decided to quit and get my health back. I was blessed to have the best Dr. in the country find a really rare lung disease that left untreated would kill me quickly (10 years). As it turns out, there is not a cure but we can slow it down considerably. I say all that because you just don't know what is going to happen next at our ages. Bladder cancer? hmmm After I had decided to retire, the medication was working miracles and I thought I had more more big effort in me so I helped start a new Classical Christian School. Handed that over and said, no I am done now, I am really tired and need a vacation. Then another non-profit calls me up and needs some help. That was last July and I will done this month. The moral of the story is enjoy the time you have. It is short no matter how long it is. If something comes along and it looks like something you want to do or in my case, it helps some people then go for it. But you get to do it because you want to and not because you have to. Sounds like you have health issues so that is a huge consideration. We have been married nearly 44 years and just took a 5 day vacation for the first time in 30+ years. I have just not been one to take time off. No more. I want to enjoy life a lot more.
Now for the numbers part. Some have suggested going to a financial planner. In my area there are several planners who offer a free consult, you may have to go to one of their free evening meals. I have been to four different people, each with a different angle (annuities, insurance, mutual funds, etc) and all three said the same thing - I am on track and we should be good if our health holds out and they couldn't really suggest much different. Social security at 62 you lose a little over 25% of the full value compared to your full retirement age. We have visited the SS office and it was good to get an idea of both my wife and I. We did learn something there. If you anticipate health being an issue, take it at 62, save what you can of it and go from there. You have to live to be around 82 for it to break even between taking at 62 and full retirement age. The big catch is your wife, when you set it and she gets yours then you set it for her for as long as she lives as she gets hers or yours (at death) whichever is greater. Then you have your 401(k), (b), etc. Find a good place to park it and figure out how much risk you want to take. I was risky in my younger days, no more. I am looking for 4-5% return and will be happy for that to be gun and vacation money with some to spare. I don't the return to live on.
Have everything paid off - this is so freeing I can't tell you. When we talk finances and tell people we owe nothing they look at us in amazement. It is rare. People at our ages are taking second mortgages and buying new homes! I will buy a new vehicle in a couple years and will pay cash. Have some case on hand - 6 months would be nice. At your age you will go through two more rounds of autos at least. That is where if you can rat hole your SS at 62, you can buy them with cash in a few years.
There are other factors as well. What is your spouse going to do? Is she going to work, how much SS or pension will she receive? Is she about the same age or wants to work a little longer. In our case, my wife loves helping kids at school but it doesn't pay hardly anything. She gets good health coverage for a few bucks and a small pension of a few hundred when she does quit. She is nearly 62 and will work to at least 65. Your case sounds a lot like mine in that you can go like this:
57 - retire - 40K
62 - SS - 22,000 (just a guess)
Wife retires 62 - pension?
wife SS at 66 - 1,000 month
Wife refiles for SS at age 70 IF she took SS at full retirement age. At 70 she will get the best of hers or half of yours.
The big monster in the closet are two fold - inflation and taxes. Inflation is bound to come back at some time. The good thing is when it does, investments usually go up with it but there is a lag time. Taxes will eat you alive in retirement. You will have no deductions to speak of and nothing but income. Anything tax deferred is sitting target for Mr. Tax man. He scoffs at the Roth IRA because he can't get his hands on that.
Finally, do what you want to do. I got burned out helping families and everyone else's kids and families and now it is time for me and my family. Life is just way way too short. Sorry this is long but this is one of my passions in life!
