Retirement Income in 2026: Withdrawal Rates, Social Security Timing, RMDs, and Guardrails

Saving for retirement has one main question: how much. Spending in retirement has several, and they interact. How much can you take from the portfolio each year? When should you start Social Security? Which account should each dollar come from, and what happens when required minimum distributions begin? This guide covers those decisions with the rules in force in 2026.

How much to save and which accounts to fund is in our retirement planning guide. Buying guaranteed income from an insurer is in our annuities guide, and the extra problems of retiring before 60 are in our FIRE guide.

What the withdrawal-rate research says

The "4% rule" comes from William Bengen's 1994 paper in the Journal of Financial Planning. He tested a portfolio of half U.S. stocks and half intermediate-term Treasuries against every retirement start date in the historical record he had. A first-year withdrawal of 4%, raised by inflation every year after that, never ran out in less than 33 years, and in most periods it lasted 50 years or more. The rate is set by the worst periods, mainly retirements that began just before the 1973-74 bear market and the inflation that followed.

Morningstar redoes the exercise each year with forward-looking estimates of returns and inflation. Its December 2025 report puts the highest safe fixed starting rate at 3.9% for a 30-year retirement, assuming a 90% chance of money left at the end and a portfolio with 30% to 50% in stocks. Its earlier estimates were 3.3% in 2021, 3.8% in 2022, 4.0% in 2023, and 3.7% in 2024. The rate moves with bond yields and stock valuations, so it is best read as a range around 4% rather than a precise figure.

Three things raise the number:

• A shorter horizon. Morningstar's tables show higher safe rates for older retirees who need 20 or 25 years of income rather than 30.
• Flexible spending. Morningstar found that retirees willing to let withdrawals vary could start near 6%.
• A larger floor of guaranteed income. The same report found that delaying Social Security pairs well with flexible withdrawal methods, because a bigger check reduces how much the portfolio has to supply in bad years.

A fixed rate fits people who want the same spending every year in real terms and will not adjust it. Anyone willing to adjust can start higher, as the guardrail rules below show.

Sequence of returns risk

Once you are withdrawing, the order of returns matters as much as their average.

Illustration: two retirees each start at 65 with $1,000,000 and withdraw $40,000 a year, raised with inflation. All figures are after inflation. Both get the same 30 annual returns. One gets -15%, -10%, and +5% in the first three years and +5% in each of the next 27. The other gets the same returns in reverse order, with the two losses at the end. Both sequences compound to the same total, an average of 3.73% a year.

Same returns, same withdrawals, and a gap of about $773,000 at the end, because the first retiree sold assets at low prices early on and those shares were never there to recover. At a 5% withdrawal ($50,000 a year), the losses-first retiree runs out of money in year 24, while the losses-last retiree still has $572,555 after 30 years.

Nobody knows which sequence they will get, so the strategies below are ways of limiting the damage from the bad one.

Guardrails: changing how much you spend

Guardrail rules adjust spending when the portfolio moves a lot. The best known come from Jonathan Guyton and William Klinger's 2006 paper. Its two main rules:

• If this year's withdrawal has risen to more than 120% of your starting withdrawal rate (for example, above 6% of the portfolio when you started at 5%), cut the dollar withdrawal by 10%. The paper stops applying this rule in the last 15 years of the planning horizon.
• If the withdrawal has fallen below 80% of the starting rate, raise it by 10%.

With those rules, the paper found starting rates of 5.2% to 5.6% sustainable at its 99% confidence standard for portfolios with at least 65% in stocks, and as low as 4.6% with 50% in stocks. The price is that spending can fall in real terms and stay lower.

Illustration: the same two sequences as above, now with a retiree who starts at 5% ($50,000) and follows simplified versions of the two rules.

The guardrails kept the losses-first retiree from running out, but the cost was real: three 10% cuts in five years, then 26 years at $36,450, below what the fixed 4% retiree spent. In the good sequence, the guardrail retiree spent $10,000 a year more than the fixed 4% retiree for 30 years. That trade suits households with a large share of discretionary spending, or a pension and Social Security that cover the basics, and suits poorly those whose budget is mostly fixed costs.

Buckets: changing what you sell

A bucket plan splits the portfolio by when the money will be spent: one to three years of withdrawals in cash and short-term bonds, several more years in intermediate bonds, and the rest in stocks. You spend from the cash bucket and refill it from stocks after good years and from bonds after bad ones.

Buckets don't change the overall math much. A portfolio with two years of spending in cash and 40% in bonds has the same total allocation whether you call part of it a bucket or not, and the long-run result depends mostly on that allocation and on how much you withdraw. What buckets do well is behavioral: seeing two years of spending set aside makes it easier to leave stocks alone in a crash, which is when selling does the most harm. They also give a simple rule for which asset to sell each year.

The two methods combine well. Guardrails set the amount; buckets decide where it comes from.

Social Security: when to claim

For anyone born in 1960 or later, full retirement age is 67. The Social Security Administration's rules:

• Claiming at 62 pays 70% of the full benefit, a permanent reduction (SSA).
• Each year you wait past 67 adds 8%, or two-thirds of 1% a month, until 70 (SSA).
• Benefits rise each January with inflation. The 2026 cost-of-living adjustment was 2.8%.
• If you claim before full retirement age and keep working, SSA withholds $1 of benefits for every $2 you earn above $24,480 in 2026. In the year you reach full retirement age, it withholds $1 for every $3 above $65,160, counting only earnings before that month (SSA). Withheld benefits are added back through a higher benefit once you reach full retirement age.

Illustration: someone whose full benefit at 67 is $2,000 a month. All amounts are in current dollars, since cost-of-living adjustments apply the same way whenever you claim.

Claiming at 67 overtakes claiming at 62 at about 78 years and 8 months. Claiming at 70 overtakes 67 at about 82 and a half, and overtakes 62 at about 80 years and 4 months. If you count money received sooner as worth more, at 2% a year above inflation, the break-even for 70 versus 62 moves out to about 82 years and 9 months.

Break-even ages understate the case for waiting in two situations:

• Married couples. When one spouse dies, the survivor keeps the larger of the two benefits, including the delay credits. The higher earner's claiming age therefore sets the survivor's income, possibly for decades.
• Longevity insurance. Delaying buys more lifetime income that rises with inflation, which few other products offer. Waiting from 67 to 70 in the illustration costs $72,000 of forgone checks, which you would draw from savings, and adds $5,760 a year for life, adjusted for inflation.

Claiming early can make sense for single people in poor health, for the lower earner in a couple, and for anyone who would otherwise have to sell investments in a deep market decline to bridge the gap.

The program's finances belong in the plan too. The 2026 Trustees Report projects that the retirement trust fund's reserves will run out in the fourth quarter of 2032, after which incoming taxes would pay 78% of scheduled benefits unless Congress changes the law. A plan that still works at about 80% of the promised benefit is a sensible stress test.

Required minimum distributions

SECURE 2.0 raised the age at which you must start withdrawing from traditional IRAs and 401(k)s. Under the IRS's 2024 regulations, it is 73 for people born from 1951 through 1958 and 75 for people born in 1960 or later. The law is ambiguous for people born in 1959; the IRS proposed treating them as 73, and until that is finalized that is the age to plan on.

The IRS RMD FAQs cover the mechanics:

• The first RMD is for the year you reach the starting age, but you can wait until April 1 of the next year. If you do, you take two RMDs in that second year, both taxable.
• Missing an RMD brings a 25% excise tax on the shortfall, reduced to 10% if you correct it within two years.
• Roth IRAs and designated Roth accounts in 401(k) and 403(b) plans have no RMDs while the owner is alive.

The amount is the prior December 31 balance divided by a factor from the IRS Uniform Lifetime Table in Publication 590-B. The factor is 26.5 at 73 and 24.6 at 75, so a $1,000,000 IRA produces a first RMD of $37,736 at 73 or $40,650 at 75. The percentage rises every year after that.

RMDs become a problem when they push you into a higher bracket, raise the taxable share of Social Security (up to 85% of benefits can be taxed, per the IRS), or lift income over the Medicare surcharge thresholds. People with large pre-tax balances can reduce future RMDs by withdrawing or converting to Roth in the years between retirement and the start of RMDs, often when income is lowest. From 70½ you can also send up to $111,000 in 2026 directly from an IRA to charity as a qualified charitable distribution, which counts toward the RMD without being taxed. Our investment tax planning guide works through a Roth conversion and the Medicare surcharge brackets in detail.

Which account to draw from

The traditional order is taxable accounts first, traditional IRAs and 401(k)s next, and Roth accounts last, so tax-advantaged money grows longest. It is simple, and it tends to produce very low taxable income in the early years of retirement followed by large RMDs later.

A mixed approach usually costs less tax over a lifetime:

1. In the years between retirement and Social Security or RMDs, take enough from traditional accounts, or convert enough to Roth, to fill the lower brackets. Spend taxable savings for the rest.
2. Once Social Security and RMDs start, cover spending with those first, then with taxable savings.
3. Keep Roth money for years with unusual expenses, such as a new roof or a large medical bill, when an extra traditional withdrawal would push you into a higher bracket or a Medicare surcharge tier. Roth money is also the best asset to leave to heirs who are in high brackets.

Asset location matters here too: holding bonds in traditional accounts and stocks in Roth and taxable accounts changes which account grows fastest. Our tax-efficient investing guide covers placement.

Putting a floor under spending

Many retirees split spending into essentials (housing, food, insurance, taxes) and the rest. Covering the essentials with income that doesn't depend on markets, meaning Social Security, a pension, and possibly an annuity, lets the portfolio take more risk and lets guardrail cuts fall only on discretionary spending. Our annuities guide works through an income-floor example with current payout rates.

Dividend stocks, REITs, and bond ladders can all supply cash, but none of them are guaranteed, and spending only the income a portfolio yields is a withdrawal rule in disguise. What matters is total return and how much you take. Our guides to dividend investing and REITs cover those assets.

A yearly routine

1. In December, check the portfolio balance against your guardrails and set next year's withdrawal.
2. Take any RMD and decide on Roth conversions before year-end, when you know the year's income.
3. Refill the cash reserve from whichever assets are above target.
4. Rebalance. Our rebalancing guide covers thresholds and taxes.
5. Review the plan when something big changes: a death, a move, a large gift, or a health diagnosis.
