The Retirement Countdown: What to Fix at 5 Years, 3 Years and 1 Year Out

Retirement planning isn't a single decision made at one age. Advisors who work with people approaching the exit increasingly describe it as a sequence of checkpoints — five years out, three to five years out, and inside the final year — each with its own list of fixes.

Why the Retirement Decision Window Now Spans a Decade, Not a Date

The average American stops working earlier than the system is built around. As of 2024, the average retirement age was 64.6 for men and 62.6 for women, according to research on average U.S. retirement ages from the Center for Retirement Research at Boston College. Full retirement age for Social Security, meanwhile, is 67 for anyone born in 1960 or later — meaning most people are making benefit and withdrawal decisions years before the system treats them as "full retirement age."

That gap matters because of what financial planners call sequence-of-returns risk: the danger that a market downturn hitting early in retirement, combined with ongoing withdrawals, can permanently shrink a portfolio in a way the same downturn wouldn't if it happened later, according to an explainer on sequence-of-returns risk from Northwestern Mutual. Claiming Social Security at the wrong time compounds the exposure: a National Bureau of Economic Research paper on Social Security claiming losses found that suboptimal claiming can reduce lifetime disposable income by a median of $182,370 — a modeled estimate that varies by earnings history and household situation rather than a fixed number for every retiree. That risk sits on top of the broader inflation pressure reshaping retirement math in 2026, which changes how far a given withdrawal rate actually stretches.

The Claiming-Age Math: How Waiting to 70 Reshapes a Monthly Check

Because full retirement age sits above when most people actually stop working, the claiming decision is where the countdown checklist starts. Delayed retirement credits add roughly 8% to a benefit for every year a claim is postponed past full retirement age, up to age 70 — after which the credits stop accruing entirely.

The dollar effect of that math is visible in the Social Security Administration's own benefit data. According to SSA-sourced data on benefits by claiming age, the average monthly retired-worker benefit climbs from $1,424.40 at age 62 to $2,016.48 at the full retirement age of 67, and up to $2,274.68 at age 70 — a gap of roughly $850 a month between the earliest and latest claiming ages. That progression is also the backbone of the payroll-cap fight now shaping Social Security's 2032 funding cliff, since higher average claimed benefits interact directly with the program's financing timeline.

The Three-Horizon Checklist Advisors Are Actually Using

The checklist changes shape depending on how far out retirement is. At the five-year mark, a five-year retirement checklist centers on arithmetic: multiplying expected annual withdrawals by 25 to sanity-check whether savings are on track, paying down high-interest debt, and starting to dial back stock exposure.

Morningstar's retirement-planning director Christine Benz frames the three-to-five-year stretch differently: it's the window for "preemptive spending" — taking a big trip or replacing a car in cash — before portfolio withdrawals actually begin, according to a checklist for retiring in three to five years. Inside the final year, the list gets more mechanical: build a budget for the first decade of retirement, settle on a Social Security claiming strategy, confirm the withdrawal rate is sustainable, decide the order in which accounts get tapped, and set aside one to two years of spending in cash — Bucket 1 — according to a checklist for retiring in one year or less.

The 2028 Deadline Hiding Inside the Senior Tax Deduction

One item on the countdown checklist has a hard expiration date attached to it. Under the One Big Beautiful Bill Act, filers aged 65 and older can claim a bonus deduction of $6,000 for single filers or $12,000 for joint filers, on top of the existing standard deduction, according to IRS guidance on the new senior bonus deduction. That deduction is scheduled to expire after the 2028 tax year under current law, which means anyone retiring within the next five years will spend part of their retirement inside the deduction window and part of it after the window closes.

None of this replaces individualized tax or investment advice — the deduction phases out at higher incomes, and the right claiming age depends on health, marital status, and other income. But the checklist itself is dated: what to check five years out is different from what to check one year out, and the 2028 sunset means the deduction question has its own clock, separate from the retirement date itself.
