DevilPlate provided the figures above: $426K at age 65 will generate a Standard Plan payout of $3.3K per month for life. So let's now look at what annualized interest rate/yield you'd need to generate the same amount of income and self-insure against longevity risks. We'll look at two terminal ages: age 100, and age 105. Here we go!
1. To sustain a $3.3K level monthly payout from age 65 to age 100 (420 months) with a $426K starting principal would require an annualized net yield of about 9.3% (a little over actually). Wow!
2. To sustain a $3.3K level monthly payout from age 65 to age 105 (480 months) with a $426K starting principal would require an annualized net yield of about 9.5% (also a little over). Wow again!
OK, don't like age 100? Think you want to gamble and only defend against 30 years of longevity risk?
3. To sustain a $3.3K level monthly payout from age 65 to age 95 (360 months) with a $426K starting principal would require an annualized net yield of about 9.0% (also a little over). Yikes!
Check my math, please.

It's
really expensive to self-insure against longevity risks.
