The 4% Rule Is Now the 3.9% Rule. Here's What Changed for 2026

Oil slipped below $100 and the Dow rose 236 points, but a chip sell-off pulled the Nasdaq down.

The quick scan: A choppy, headline-driven week ended on a split note. The Dow eked out a gain while the Nasdaq slid, oil retreated after briefly topping $100 on Middle East tensions, and investors braced for a heavy run of Big Tech earnings and a Fed meeting next week. It is the kind of week that rattles anyone who watches a portfolio daily, which is exactly why today's article steps back from the noise to ask a calmer question: how much can you actually spend from your savings each year without running out?

S&P 500: +0.05% to 7,411.98 – barely positive, with every sector except technology finishing the day higher
Dow Jones: +0.46% to 51,947.25 – up 236 points, carried by Salesforce, IBM and Apple, even as American Express fell after a revenue miss
NASDAQ: -0.64% to 24,975.82 – chipmakers led the retreat as fresh worries about Big Tech's spending plans weighed on growth names.

What's driving it: Two forces pulled in opposite directions. Oil eased, with US crude down about 3.5% to roughly $89 a barrel after briefly clearing $100 earlier in the week, helped by a report that Pakistan, backed by China, might broker talks between the US and Iran. That relief lifted parts of the market. Working the other way was a sharp sell-off in technology and chip stocks, as underwhelming earnings reactions from Alphabet and Tesla put a spotlight on how much these companies are spending on artificial intelligence. The Magnificent Seven shed close to $797 billion in a single session on Thursday, and the aftershocks carried into Friday. With Microsoft, Meta and Apple all reporting next week, and a Fed meeting on the calendar, investors settled into a wait-and-see mood.

Bottom line: Weeks like this one are noisy, but noise is not a plan. War headlines, an oil spike that faded, a tech tumble – none of it tells you what to do with your own money on Monday morning. For retirees drawing an income, the more useful question is not "what did the market do today" but "what can I safely take out this year." That is exactly what today's article digs into, and it is a far steadier anchor than any single session.

How Much Can You Actually Spend in Retirement Without Running Out?

The scoop: For about thirty years, retirees had a comforting rule of thumb to lean on. Take out 4% of your savings in your first year of retirement, give yourself an inflation raise each year after, and the odds were good your money would outlast you. Four percent. Simple enough to scribble on the back of an envelope. On a $500,000 nest egg, that is $20,000 in the first year. Memorable, tidy, and for a long stretch, roughly right.

So it is a little unsettling to hear the number has been quietly nudged again. According to Morningstar's latest research on safe withdrawal rates, a person retiring in 2026 should start at 3.9%, not 4%. On that same $500,000, we are talking about $19,500 instead of $20,000 – a difference of $500 a year, or less than ten dollars a week. Hardly a catastrophe. But the small change is worth some thoughts, because the thinking behind it is far more useful than the number itself.

A number that keeps moving

Here is something the napkin version never told you: the "safe" rate is not fixed. Morningstar has run this study for years, and the figure wanders. It was 3.3% back in 2021, climbed to 4.0% in 2023, then eased to 3.8%, then 3.7%, and now sits at 3.9% for 2026 – actually a small step up from last year. The reason it rose this time is almost boringly technical: bond yields are healthier, so a steady portfolio can now throw off more reliable income than it could a couple of years ago. The lesson is not that 3.9% is the new gospel. It is that any single "safe number" is really just a snapshot of the conditions on the day it was worked out.

What the 3.9% actually assumes 

This is where a lot of people quietly trip up. That figure is built on a specific recipe: a portfolio holding somewhere between 30% and 50% in shares with the rest in bonds and cash, a 30-year retirement, and a 90% chance of not running out. Notice it is not an all-shares portfolio. You might expect more shares to allow more spending, but Morningstar found the opposite. A share-heavy portfolio swings around too much, and a bad run of returns in your early retirement years can do lasting damage. Calm and boring, it turns out, supports a steadier paycheck.

One more thing the researchers keep underlining: you do not re-set your withdrawal to each year's fresh headline rate. You pick the rate for the year you retire, then simply give yourself an inflation adjustment each year after. Chasing the annual figure up and down would defeat the whole point.

The part worth reading twice

If the story ended at "3.9%," it would be a footnote. The genuinely interesting finding is what happens when you allow yourself to be a little flexible. Morningstar tested eight different flexible spending approaches, and the most generous of them lifted the safe starting rate as high as 5.7%. That is a meaningfully bigger income from the very same savings.

The catch, naturally, is that flexibility means your income wobbles. Some of the methods are simple enough to picture: skip your inflation raise in any year the portfolio fell, for instance. Others use "guardrails" – spend a bit more when markets are kind, trim a bit when they are not. One approach caps how much your income can climb in a good year and limits how far it drops in a bad one, smoothing out the ride. None of these is exotic. They just ask you to treat your spending as a dial you can turn, rather than a thermostat locked at one setting.

Whether that trade is worth it is a personal question, and the researchers say as much. If most of your essential bills are already covered by a pension or other guaranteed income, wobbles in the rest are easy to live with. If your portfolio is what pays for the groceries, a variable income is a far more nervous business.

The curveballs

The report also pokes at the things that can knock a plan sideways. Retiring early is a big one. Stretch the plan from 30 years to 35 and the safe starting rate slips from 3.9% to 3.5%, and that is before you reckon with paying for your own health cover in the years before Medicare kicks in, which the report notes can run $800 to $1,200 a month or more. The possibility of long-term care later in life tugs the number down in much the same way, to around 3.5%. A burst of high inflation early in retirement is another threat, and, tidily, one of the best defences against it is the same flexible spending you were already being nudged toward.

So what do we do with all this? 

Not panic, for a start. If you are reading this from Kuala Lumpur, Singapore, or anywhere outside the United States, the exact 3.9% is not your number. It is built on US markets and US assumptions, and your own mix of pensions, savings and safety nets will look different. But the shape of the idea travels beautifully. Start from a sensible, tested rate rather than a hopeful guess. Keep enough steadiness in your portfolio to survive a rough patch early. And treat your spending as something you can adjust, not a vow you made on day one. The magic was never really in the number. It is in having a method calm enough that a week like the one the markets just had does not send you reaching for the panic button.

Actionable takeaways for L-Plate Retirees:

• Start from a tested rate, not a hope. A figure like 3.9% is not magic, but it beats a number you picked because it felt about right. Anchor your first-year withdrawal to research, then build from there. Even a modest, evidence-based starting point gives you something solid to adjust from when life changes.

• Keep ballast in the boat. The safe rate assumes only 30% to 50% in shares for a reason. Enough steadiness to ride out a bad early spell matters more than squeezing out the last drop of growth, because a rough patch in your first few retirement years does the most lasting harm.

• Choose your rate once, then just index it. Do not chase every year's new headline number. Set your starting withdrawal in the year you retire, give yourself an inflation raise after that, and let the plan breathe. The safe rate is a snapshot of one year's conditions, not a knob you are meant to keep turning.

• Treat spending as a dial, not a thermostat. Being willing to trim in down years and spend a little more in good ones can lift your sustainable income substantially. The trade-off is a wobblier paycheck, which is easiest to stomach when your essentials are already covered by guaranteed income.

• Rehearse the curveballs before they arrive. Retiring early, a long spell of care, or an early burst of inflation can all pull your safe rate down toward 3.5% or lower. Better to picture those on a quiet afternoon now than to meet them by surprise later, and a plan that has met them on paper tends to hold up when they arrive in person.

Your Turn: 
If your retirement income had to wobble a little in order to stretch further, could you live with the ups and downs, or would the uncertainty cost you sleep? 
Which of your essential expenses are already covered by guaranteed income, and which ones lean on your portfolio? 
When you picture running out of money, is that fear built on a plan you have actually tested, or on a number you are quietly hoping is enough?
