You're correct, that's a bad example. Using the same numbers, I can do this instead:
A 65-year old man who pays $150,000 for an SPIA would get about $10,260 each year for the rest of his life.
But, if that 65-year old man pays $19,000 for a deferred no-surrender-value annuity, he would get about $10,260 per year starting at age 85 and continuing for the rest of his life.
That would leave him with $131,000 to provide income for 20 years, if he lives that long.
Or to provide a lump sum (some portion of the $131,000) for medical or personal care if he develops serious health problems and dies long before 20 years.
Or, to provide an inheritance for his kids if he dies suddenly before 20 years.
I'm not saying the deferred annuity is necessarily better, just that this example shows the trade-offs more clearly.
