Frequently Asked Questions

Period certain vs life-only payout?

Life-only pays the most monthly but stops at death; period-certain guarantees payments for N years regardless. Insurers price longevity out of the guaranteed version.

How does inflation hit fixed payouts?

At 3% inflation fixed purchasing power halves in about 24 years. COLA riders exist but start roughly 30% lower.
