Miss one deadline, and you pay for it for life.

Social Security and Medicare are not hard because the rules are complicated. They are hard because nobody explains them in order. You get glossy mail and a phone call from someone who wants to sell you a plan. What you do not get is a plain list of your own decisions and your own dates.

This book is that list. Sixteen short chapters that explain every decision in the order you actually face it — and the pages to write your own answers down. No jargon. No sales pitch.

Every window, counted from your birthday

Not a generic table. The book counts the enrollment windows from your own date of birth — and names the penalties that never go away.

When to claim, as arithmetic

What waiting is really worth, the honest case for claiming early, and the decision most couples get wrong: how one spouse's timing sets the survivor's income for life.

The honest plan comparison

Original Medicare with Medigap, or Medicare Advantage — including the door that only swings one way. Part D picked by your medication list, not by the premium.

All 50 states at a glance

The Medigap switching rights that 23 states give you and nobody mentions, plus the free SHIP counselor's number for every state and the questions to ask when you call.
