As of next year this will be an option for the first time (due to benefit changes). My question I guess is how do I mathematically figure out if it is "better" to live off savings for a year and have the pension increase by 5% or whatever. I have pretty small set of assets but I have never considered this option because it has always been tied to other things like the retiree health insurance. Which i still want and am not at the correct age for yet. I could not last the number of years needed to get me to medicare or even full pension but . . . IDK. Pension is reduced at 55, full at 62.
