Question 1 — do you have your number?
Start with how much you need saved to cover the gap between your spending and guaranteed income like Social Security or a pension. The calculator above estimates that target. If your savings are at or above it, timing becomes a choice; if not, it tells you how much longer you likely need to work.
Question 2 — what happens to healthcare?
Medicare doesn't start until 65. Retiring earlier means bridging healthcare yourself — through a spouse's plan, COBRA, or the marketplace — and that cost is easy to underestimate. Price it out before picking a retirement date, especially if you're retiring before 65.
Question 3 — what does claiming early or late cost you?
Social Security and many pensions pay less if you claim before full retirement age, and can pay more if you delay. The break-even calculator and early retirement reduction calculator show what timing costs or gains you.
Question 4 — can your portfolio survive a bad first few years?
Retiring right before a market downturn is one of the biggest risks in retirement planning — withdrawing from a shrinking portfolio early can do lasting damage. The withdrawal rate calculator and how long will savings last calculator help you stress-test the plan.
Putting it together
There's rarely one perfect date — it's a trade-off between working longer for a bigger cushion and having more healthy years to enjoy retirement. Running the numbers above at a few different ages usually makes the right window obvious.
Common questions
Is there a magic retirement age? No — 65 is a healthcare milestone (Medicare) and full retirement age varies by birth year, but your real answer depends on your own numbers.
Should I retire mid-year? Sometimes useful for maxing out a final year of contributions or benefits — check your specific plan's rules.
What if the market drops right after I retire? This is sequence-of-returns risk — a cash cushion or flexible spending in the first few years helps protect against it.
