Retirement planning

Retirement planning is the work of matching the money you set aside during your working years to the life you want after the paychecks stop. Investing is only part of it. The full job takes in when to claim Social Security, how to cover health care before and after Medicare begins, where you will live, how savings become monthly income, and what happens to your accounts when you die.

A generation ago, employers and the government decided much of this for workers. A company pension paid a fixed check for life, and the main choice was when to stop working. Today traditional pensions cover a shrinking minority, and most private-sector workers save through defined contribution accounts such as the 401(k), where the saving rate, the investment choices, and the pace of withdrawals are all up to you. The shift moved both the responsibility and the risk onto individuals.

The mechanics are learnable, though, and starting pays off at any age. Someone who begins at 50 with modest savings has real tools available: higher contribution limits, a mortgage that may soon be paid off, and as many as 20 or more years of compounding still ahead. This article maps the pieces and points to the detailed articles on each one.

What retirement planning covers#

Six questions organize most of the work. How much do you need to save, and in which accounts? When will you retire, and when will you claim Social Security, two dates that are related but not the same? How will you pay for health care, including the long-term care that Medicare does not cover? How will you turn a pile of savings into a reliable monthly income? How will taxes change once your income comes from benefits and withdrawals instead of wages? And is your paperwork in order: beneficiary designations, a will or trust, and the documents covered in estate planning?

None of these has to be settled at once, and the answers change as your life does. A useful plan is less a binder than a habit: check your progress once a year, adjust contributions when your pay changes, and revisit the big decisions as each milestone age approaches.

How much is enough#

Rules of thumb are rough, but they give you something to steer by. Fidelity's widely cited guideline suggests saving about one year's salary by age 30 and roughly ten times your final salary by 67 ¹.

Those targets assume you save about 15 percent of your income each year (counting any employer match), invest at least half of it in stocks over your career, and retire at 67 ¹. They also assume Social Security does part of the job. For an average earner, Social Security replaces roughly 40 percent of pre-retirement income, and a smaller share for higher earners ², which is why personal savings must fill the rest.

A more precise answer starts from spending rather than salary. Estimate what a year of retirement will actually cost you, subtract Social Security and any pension, and the gap is what savings must produce. One common cross-check: multiply that annual gap by 25, which corresponds to an initial withdrawal rate of 4 percent. The reasoning behind that number, and its limits, are covered in retirement withdrawal strategies, and budgeting in retirement walks through building the spending estimate itself.

Planning by decade#

Your 40s#

Time is still your biggest asset. A dollar invested at 45 has two decades to grow before a retirement at 65, so raising your saving rate now does more than almost anything you can do later. The 3x-by-40 benchmark is a checkpoint, not a verdict; falling short is common, and the response that works is increasing contributions a percentage point or two each year, ideally automatically with raises.

Two other tasks belong to this decade. The first is deciding, deliberately, how college costs and retirement saving will share your budget; students can borrow for school, but nobody lends for retirement, which is why many families treat retirement contributions as the bill that gets paid first. The second is creating a my Social Security account at ssa.gov and checking your earnings record, since errors are easier to fix while the paper trail is fresh.

Your 50s#

At 50 the tax code starts helping. Catch-up contributions let you save beyond the normal limits: in 2026 that means an extra $8,000 in a 401(k), for a total of $32,500, and an extra $1,100 in an IRA, for a total of $8,600 ³. From ages 60 through 63 a higher 401(k) catch-up of $11,250 applies if your plan offers it ³.

This is also the decade to price long-term care insurance if you want it, since premiums rise and health underwriting tightens with age, and to run your first serious retirement budget. Try living on your projected retirement income for a few months while still working; the experiment costs nothing and surfaces problems early. Finally, plan for the possibility of leaving work sooner than intended. In the Employee Benefit Research Institute's long-running survey, workers most often expect to retire at 65 or later, but the median retiree actually left at 62, and nearly half retired earlier than planned, usually because of health or a layoff ⁴.

Your 60s#

The decisions now arrive on a schedule, described in detail in retirement age. You can claim Social Security as early as 62 at a permanently reduced amount, wait until your full retirement age of 66-67, or delay to 70 for the largest check; the tradeoffs are the subject of when to claim Social Security. Medicare begins at 65 whether or not you have retired. Required minimum distributions from most tax-deferred accounts start at 73 ⁵.

If you hope to retire before 65, price the health coverage bridge first, because a few years of individual insurance premiums can undo other math. Many people also ease out rather than leave at once. Working part time in the early years shortens the stretch your savings must cover and can let you delay your Social Security claim.

Note: Medicare has firm deadlines. Missing your initial enrollment window around your 65th birthday can mean permanently higher premiums. The dates and exceptions are covered in Medicare enrollment periods.

Retirement accounts at a glance#

Most retirement saving happens in four kinds of tax-advantaged accounts. The 2026 limits below are set by the IRS and adjust most years ³. Health savings account figures come from separate IRS guidance ⁶.

The HSA is technically a health account, but it doubles as retirement savings because unspent balances roll over year after year and can be invested. You must be enrolled in a high-deductible health plan to contribute, and contributions stop once you enroll in Medicare ⁶.

A common sequence among savers with limited dollars: contribute enough to the workplace plan to collect the full employer match, since a match is an immediate return no investment can promise, then direct additional savings to whichever of the other accounts fits your tax situation. Whether pre-tax or Roth treatment serves you better depends on your tax bracket now versus in retirement, a comparison drawn out in the Roth IRA article.

Where retirement income comes from#

Retirees rarely live on one source. Social Security is the foundation for most households, replacing about 40 percent of an average earner's pre-retirement income ², and it is the only common source that is both inflation-adjusted and guaranteed for life. Personal savings usually rank second, drawn down through a withdrawal plan or partly converted to guaranteed lifetime income through an annuity. Pensions still matter for government workers and some private employees. Work itself is a source for many retirees, though earnings before full retirement age can temporarily reduce Social Security checks under the program's earnings test.

Home equity is the quiet fifth source. Selling and moving somewhere cheaper frees up cash directly, though transaction costs eat part of the gain. Borrowing against the home through a reverse mortgage is possible but has enough moving parts that it deserves its own careful reading.

Common mistakes#

Claiming Social Security at 62 by default. Claiming at the earliest age permanently reduces the monthly benefit, and the reduction compounds over a retirement that may last 30 years. Early claiming is sometimes the right call, particularly in poor health, but it deserves a decision rather than a reflex.

Cashing out retirement accounts between jobs. A cashed-out 401(k) loses value three ways: income tax now, usually a penalty tax on top before age 59 1/2, and all the future growth. Rolling the balance to the new employer's plan or an IRA preserves it.

Underestimating health costs. Fidelity estimates that a 65-year-old retiring in 2025 will spend an average of $172,500 on health care over the rest of their life, and that figure excludes long-term care entirely ⁷. Budgets built around today's employer-subsidized premiums tend to run low.

Assuming the retirement date is yours to choose. Since nearly half of retirees leave earlier than planned ⁴, a plan that only works if you reach 67 employed and healthy is fragile. Testing the numbers at 62 shows how much margin you really have.

Ignoring taxes and inflation. Withdrawals from pre-tax accounts are taxable income, required distributions can push you into higher brackets, and rules change: the 2025 tax law added a temporary deduction of up to $6,000 per person for taxpayers 65 and older through 2028, phasing out above $75,000 of income for singles and $150,000 for joint filers ⁸. Meanwhile, even 3 percent inflation roughly halves purchasing power over 24 years. Taxes in retirement covers what changes and when.

The five years before you retire#

The final stretch is when a vague intention becomes a tested plan. A rough countdown:

None of this locks you in. People retire, return to work, move, and change claiming plans, and the numbers can be rerun at every step. The plans that hold up are the ones checked yearly and rebuilt without embarrassment when life changes them.
