Yeah, I want to make sure I have enough money for the best walker in the neighborhood.
Here, let's do the Calculation....In case you missed the point.
Let's Say you retire this year at age 62 with the $1 Million Portfolio and decide to take a 4% SWR. You get Social Security of $19,476 per year at age 62 and delaying to age 70 would get you $34,092 per year. Let's assume no inflation for ease of calculations.
Scenario age 62. Your SWR is $40K per year and Social Security of $19,476 gets you a Spending total of $59,476 for each year of your retirement period.
Scenario age 70. You stash 8 years of $34,092 from your portfolio into a savings account for a total of $272,736. Your portfolio is now down to $727,264. Your 4% SWR is now $29,090 per year and you remove $34,092 from your savings account giving you a total of $63,182 to spend each year for the rest of your 30 year retirement period.
The Delay to age 70 gives you $3,706 more every year starting at age 62 with no more increased risk. If you are of limited imagination or physical capacity, I am sure that this would buy you the best walker in the neighborhood. For myself I would opt for an extra week of Fishing in the Bahamas every year for the rest of my 30 year retirement period.
No need for any stupid 'break even analysis'.
If your WR is more conservative, such as a majority of the people here and myself, the results are even more compelling. At a 3% WR rate the age 62 scenario is a total of $49,476 and the age 70 scenario is $55,910. The delay of SS now increases your annual spending by $6,434.
