Safe Withdrawal Rate by Age Calculator (2026 Research)

3.9%. Morningstar's latest research says that starting withdrawal rate leaves money in the account in 90% of simulated futures over a 30-year retirement. That's a useful benchmark. It also assumes you're a generic 30-year retiree, and you probably aren't. If you retire at 58, your money may need to last close to 40 years. If you retire at 72, it may need far fewer. A good safe withdrawal rate by age calculator turns your age into a time horizon, runs your own numbers through many possible markets, and gives you back the odds.

This guide explains how age changes the rate, what the research says at each retirement age, where that research stops, and how to test your own plan.

The short answer: age sets your horizon

Your safe withdrawal rate isn't really about your birthday. It's about how many years your savings have to last. As Freefincal points out, age matters because it sets the length of retirement. The longer the horizon, the lower the safe starting rate.

Morningstar's numbers show this clearly:

• 30 years: 3.9% starting withdrawal rate, with a 90% chance the money lasts.
• 35 years: 3.5%.
• 40 years: lower still. Morningstar's early-retirement figures for this horizon have changed from one edition to the next, so check the current early retirement analysis before relying on a specific number.

The 3.9% base case comes from Morningstar's State of Retirement Income research (published December 2025), and it's up from 3.7% the year before. The 35-year figure comes from the same series (2025 report PDF).

One detail people miss: the "rate" applies to year one only. After that, the dollar amount rises with inflation. So in later years your withdrawal can be a bigger share of whatever is left (Freefincal).

Safe withdrawal rate by age: what the research shows

Plans here run to age 95 by default, so this table uses 95 as the end point. That's a deliberate choice. More on why below.

Notice the gap at the bottom. Plenty of people retire between 65 and 75, so 20- and 25-year horizons matter to a lot of readers. Yet none of the widely cited sources publish a Morningstar-style safe rate for them. A shorter horizon should support a higher starting rate. How much higher depends on your portfolio, your spending, and how much risk you'll accept. That's the point where a generic table stops helping and your own numbers have to take over.

There is one more age-based approach you may come across. Boston College's Center for Retirement Research built a schedule from the IRS required minimum distribution (RMD) tables. It starts at 3.13% at age 65 and rises every year after that, as the Motley Fool reported in 2018. It's a sensible rule of thumb, but it's a different method, and the article is several years old.

Why "safe" means 90% of futures, not an average

Most simple calculators assume an average return, something like 6% a year, every year. Real markets don't work that way. They lurch. And the order matters.

If you hit a bad market in the first few years of retirement, you sell investments while prices are down to cover spending. Those dollars never get the chance to recover. This is called sequence-of-returns risk: two retirees can earn the same average return over 30 years and still end up with very different results, just because the bad years came at different times.

A Monte Carlo simulation deals with this. In plain terms, it plays out your retirement hundreds or thousands of times, each time with a different random but realistic run of market returns. Then it counts how many of those futures still have money left at the end. That count is your success rate.

That's how Morningstar defines "safe": the money is still there in 90% of simulated outcomes. It's why a Monte Carlo answer is a probability, not a promise.

Horizon changes those odds a lot. Using Vanguard's Monte Carlo simulator, a 50/50 stock-and-bond portfolio withdrawing 4% had about a 92% chance of lasting 30 years, but only about 78% over 50 years, according to Million Dollar Journey. It's the same rate and the same portfolio. Only the length of retirement changed.

Three methods, three different numbers

If you've seen 3.13%, 3.9%, and 4.7% all called "safe," here's why. They come from different methods:

1. Historical backtests. Bengen's original work and the Trinity Study tested withdrawal rates against past market history. Bengen's updated "4.7% rule" is a 30-year historical backtest, as summarized by ARQ Wealth. It describes what worked in the past. It isn't a forecast.
2. RMD-based schedules. The CRR approach links withdrawals to IRS life-expectancy tables. It's simple, and it rises as you age.
3. Forward-looking Monte Carlo. Morningstar projects future returns from today's valuations and runs simulations. This is why its number moves from year to year.

None of these is "wrong." They answer slightly different questions. When you compare rates by age, check which method produced each one.

What moves your rate besides age

Longevity

About one in three 65-year-olds may live to at least 90, according to the Social Security Administration's Retirement Information for Medicare Beneficiaries (2026). A plan that ends at 85 is quietly betting against a third of retirees. That's why the plan you build here runs to 95 by default, and you can push it further.

If you're planning as a couple, the horizon usually runs longer still. The money has to last until the second partner dies, and that tends to be later than either person's life expectancy alone.

Health care

Fidelity's 2025 Retiree Health Care Cost Estimate (July 2025) puts lifetime health care costs at $172,500 for a single 65-year-old retiring this year. That covers Medicare premiums, deductibles, and prescriptions. It doesn't include long-term care at all. Costs on that scale change how much you can safely draw for everything else.

Spending flexibility

The 3.9% figure assumes fixed, inflation-adjusted withdrawals. If you're willing to cut back after bad years, Morningstar's 2026 research suggests starting withdrawals approaching 6% (Morningstar). The same research found that portfolios with 30–50% in stocks supported the highest safe starting rates.

Guaranteed income

Social Security, a pension, or an annuity covers part of your spending, so your portfolio carries less of the load. When that income starts matters too. Delaying Social Security can mean drawing more from savings early on and less later. None of the ranking calculators show this by age, and it can change your answer a lot.

How to use a safe withdrawal rate by age calculator

Three numbers get you started.

1. Your age. This sets the horizon. At 62 with a plan to 95, that's 33 years.
2. What you've saved for retirement. Use the total of your invested retirement savings.
3. What you spend each month. Be honest here. Nearly half of workers (48%) have never estimated what they'll need each month in retirement, according to the EBRI/Greenwald Retirement Confidence Survey 2025. Doing it puts you ahead.

You can do a quick check yourself. Multiply monthly spending by 12, then divide by savings. Spending $3,000 a month from $800,000 works out to $36,000 a year, or a 4.5% withdrawal rate. That's above Morningstar's 30-year base case. It doesn't mean the plan fails. It means you should look at the odds.

That's what the Monte Climb retirement calculator does. It takes those three numbers, runs them through 1,000 simulated futures, and tells you how many stay funded. It runs in your browser, and nothing is saved until you choose to save it.

Then stress-test the plan. Change one thing at a time:

• Retire two years later. How much does the success rate improve?
• Cut monthly spending by a few hundred dollars.
• Push the horizon past 95.

Break your plan on purpose, before life does. If you'd like help reading the result, you can ask William, our AI planner, questions like "Am I on track?" or "Can I retire at 62?" He shows his work.

One honest caveat: this is planning software, not advice. A success rate tells you how your plan held up across many possible futures. It can't tell you which future you'll get.

Find your own rate

Generic tables can only take you so far, and they mostly stop at age 65. Your rate depends on your horizon, your spending, and how much uncertainty you can live with.

Frequently asked questions

What is the safe withdrawal rate by age?

Age matters because it sets how long your money must last. Morningstar's research puts the safe starting rate at 3.9% for a 30-year retirement (roughly retiring at 65 and planning to 95) and about 3.5% for 35 years. Longer horizons support lower rates, and shorter ones generally support higher rates.

Is the 4% rule still safe in 2026?

Morningstar's base case for 2026 is 3.9% for a 30-year retirement with a 90% chance of success, up from 3.7% the year before. So 4% is close, but slightly above that benchmark if you use fixed, inflation-adjusted withdrawals. If you're willing to adjust your spending, Morningstar's research suggests starting rates approaching 6%.

Can I withdraw more if I retire at 70 or 75?

Generally, yes. A 20- or 25-year horizon supports a higher starting rate than a 30-year one. Morningstar doesn't publish base-case figures for those horizons, though, so running your own numbers through a Monte Carlo simulation is the most reliable way to see your odds.

What does a Monte Carlo success rate mean?

A Monte Carlo simulation runs your retirement through many randomized but realistic market paths and counts how many still have money left at the end. If 900 of 1,000 simulated futures stay funded, that's a 90% success rate. It's a probability, not a guarantee.

What age should a retirement plan run to?

The Social Security Administration says about one in three 65-year-olds may live to at least 90. Planning to 95 or beyond lowers the risk of running out of money, and couples may need to plan even longer, until the second partner dies.
