Bentley,
It's silly for me to tell you not to worry since you will anyway. This is a big event. Everyone worries when the paychecks from work stop and the checks from investments begin.
I say this from personal experience as well as years of reader letters. Humberto Cruz, a fellow syndicated columnist, continues to write his column even though he has no financial need to do so. I'm doing the same thing and I have no financial need to continue writing, either. I joke that I continue writing because I never learned to play golf. But the truth is I'm not ready to assume my new identity as Mr. Leisure.
All I can do is remind you that worry won't change anything. Better still, you're in very good shape.
Indeed, you're in better shape than you think. And your standard of living in retirement, even early retirement like yours, can be higher than the $55,000 of spending that you're thinking about. You sent enough data that I was able to make a basic consumption smoothing study using ESPlanner. That's the software that Kotlikoff and I used as the foundation for "Spend 'til the End," our trade book on financial planning.
You can learn more about ESPlanner at the website, www.esplanner.com. For the record, I have no financial stake in this firm. It just happens to offer the best tool for consumption smoothing, an approach to financial planning that I have been interested in since before I wrote my first book on personal finance way back in 1971. My hope is that it will change the standard of care for financial planning and prevail over some of the idiocy that is passed off as financial planning by the financial services industry.
Using your input data, I assumed a future inflation rate of 4.0 percent and an investment return of 7.5 percent. That's a real return of 3.5 percent, so it will require taking some risk. It's a set of assumptions, however, that most would regard as pretty conservative. I explored options of (1) buying or mortgaging the new home, (2) investing all your money or buying a life annuity with 25 percent of your financial assets, and (3) delaying taking Social Security benefits until you are 67 and your wife is 65.
The smoothest path I could find was to take Social Security benefits at 62, not take an annuity, and mortgage the new house for its construction cost for about 15 years. That would provide you with lifetime consumption income of about $65,000 a year. This is over and above the income taxes you would need to pay, your future Medicare premiums, and any money (including mortgage) that you would pay for the cost of your primary home.
Delay taking Social Security benefits until you're 67 and she's 64 and you'll lose a little spending power today but gain more when you take Social Security benefits. To be specific, your current consumption will have to drop to about $58,000 while your future consumption will rise to a bit over $73,000. Basically, you'll give up about $7,000 a year for 10 years to gain $8,000 a year for at least 35 years. (Note: all these figures are in constant value dollars.) If you are seriously thinking of working part-time in the near future, this is definitely the route to choose--- your standard of living will be higher than you currently expect and still higher in the future.
In all cases I assumed that you and your wife would each live to age 100. You would be 'spending 'til the end' in that at that age you would have no financial assets left and your only asset would be the value of your house. Since this is assuming that each of you will live more than 40 years, a substantial margin of safety is built-in. One of you might live to 100 but the odds are very much against it. Your estate will most likely have both your house and financial assets.
Lots can be done to refine this, including Monte Carlo analysis to estimate the risk of future spending declines, but this should reduce your worry a bit.
