Retirement Planning Essentials
How much you'll need, which accounts to use, the 2026 contribution limits, when to claim Social Security, and the Medicare and RMD deadlines that catch people out.

Retirement planning comes down to three questions: how much will you spend each year once you stop working, where will that money come from, and how do you get from here to there? You don’t need exact answers to start. Saving consistently in the right accounts, and avoiding a few expensive mistakes around Social Security and Medicare, matters more than a perfect forecast.
Estimate what you’ll spend
Start with your current spending and adjust it:
- Likely lower: commuting, work clothes, payroll taxes, retirement contributions, and the mortgage, if it’s paid off.
- Likely higher: health care, travel and hobbies in the early years, and possibly help at home later.
Rules of thumb about replacing a fixed share of your income are a rough guide at best; your own line-by-line estimate is more useful. Then subtract expected income from Social Security and any pension. The gap is what your savings need to cover each year.
Use the right accounts
For 2026, the IRS limits are:
| Account | 2026 limit | Extra if 50+ |
|---|---|---|
| 401(k), 403(b), most 457 plans, TSP | $24,500 | $8,000 ($11,250 at ages 60–63) |
| Traditional or Roth IRA | $7,500 | $1,100 |
| HSA (with an eligible high-deductible plan) | $4,400 self-only / $8,750 family | $1,000 at 55+ |
Traditional accounts give you a tax break now; you pay tax on withdrawals later. Roth accounts are funded with after-tax money but grow and come out tax-free in retirement, with no required withdrawals during your lifetime. Many people use both, which gives them flexibility over their tax bill later.
An HSA is worth knowing about. Contributions are tax-deductible, growth is tax-free, and withdrawals for medical costs are tax-free, and you can let it build for decades to pay for health care in retirement.
Always contribute enough to get the full employer match.
Invest for the long haul
Retirement money you won’t touch for 20+ years can generally handle more stock market ups and downs than money you’ll need soon. As you get closer, shift gradually toward more stable investments. A target-date fund does this for you automatically. Keep fees low; a 1% annual fee can consume a large share of your growth over 30 years. Investment Fundamentals explains why.
Social Security: timing matters
For anyone born in 1960 or later, full retirement age is 67. You can claim as early as 62, but your monthly benefit is about 30% lower, permanently. Waiting past 67 adds 8% a year until 70, when your benefit reaches 124% of the full amount.
Claiming early can make sense if your health is poor or you need the income. Waiting is often worth it if you’re healthy and can cover expenses another way, especially for the higher earner in a married couple, since a surviving spouse can keep the larger benefit.

Medicare: don’t miss the window
You become eligible for Medicare at 65. Your initial enrollment period lasts seven months, starting three months before the month you turn 65. If you don’t sign up for Part B on time and don’t have qualifying coverage through a current employer, you may pay a late-enrollment penalty of 10% for each full year you went without, for as long as you have Part B.
If you’re still working at 65 with employer health coverage, you can usually delay Part B without penalty, but check the rules before you do.
Required withdrawals
Starting at age 73 (or 75 if you were born in 1960 or later), you generally have to take required minimum distributions from traditional IRAs and 401(k)s each year. Missing one triggers a penalty. Roth IRAs don’t have lifetime RMDs.
If you’re behind
It’s common, and fixable. Use catch-up contributions after 50, delay Social Security if you can, consider working a few extra years or part-time, and pay off debt before you retire. Entering retirement without a credit card balance or a car payment lowers how much income you need. Tax Planning Strategies covers ways to keep more of what you save.
