About $2.94 million before taxes is the starting estimate when a portfolio must fund $9,550 per month ($114,600 per year) under a 3.9% initial withdrawal rate. The arithmetic is $9,550 × 12 = $114,600, then $114,600 ÷ 0.039 = $2,938,462. Rounded, that is $2.94 million.
This is a planning scenario, not a guaranteed income level or personal investment recommendation. The 3.9% assumption comes from Morningstar’s February 18, 2026 retirement-income research summary, which models a 30-year retirement, inflation-adjusted spending and a 90% probability-of-success objective.

What the $2.94 million estimate actually means
The calculation treats $9,550 as the portfolio’s planned first-year withdrawal. “Withdrawal” does not mean every dollar must arrive as a dividend or interest payment. A retiree could receive some cash distributions and sell investments to supply the rest. The portfolio’s total return, not just its yield, supports the spending plan.

Under Morningstar’s fixed, inflation-adjusted method, the first-year dollar amount is established at retirement and then increased with inflation. It is not a rule to withdraw 3.9% of whatever the account happens to be worth at the start of every subsequent year. If the portfolio falls, the dollar withdrawal can remain the same in the model even though the percentage of the remaining balance rises.
#1 Best Overall
The estimate is stated before income taxes. It also assumes the portfolio supplies the entire $114,600 annual target. Social Security, a pension, annuity payments or other dependable income would reduce the amount the investments need to provide; taxes or a desired after-tax spending amount can increase the gross withdrawal.
How the withdrawal-rate calculation works
- Convert the monthly goal to an annual goal. Multiply $9,550 by 12 to get $114,600.
- Select a starting withdrawal rate. At 3.9%, the first-year withdrawal equals 3.9% of the starting portfolio.
- Divide annual spending by the rate.
$114,600 ÷ 0.039 = $2,938,462. - Round only for planning. A practical estimate is approximately $2.94 million, while a real plan should use a detailed cash-flow and tax analysis.
The rate is the key assumption. Changing it changes the principal requirement even though the spending target stays fixed.
Portfolio size at other starting withdrawal rates
| Starting withdrawal rate | Approximate portfolio for $114,600 a year | What the figure represents |
|---|---|---|
| 3.7% | $3.10 million | Calculation using the same annual target and a 3.7% starting rate |
| 3.9% | $2.94 million | Latest Morningstar starting estimate in its February 18, 2026 summary |
| 4.0% | $2.87 million | Calculation using the same annual target and a 4.0% starting rate |
These are simple divisions, not promises that any particular portfolio will last. A lower rate requires more capital but gives the plan more room for poor returns, inflation surprises and a long life. A higher rate reduces the initial balance requirement while increasing the risk that spending will need to change or the account will run short.
What Morningstar’s 3.9% framework covers
Morningstar’s February 18, 2026 summary describes 3.9% as a latest starting estimate for a modeled 30-year retirement and a 90% probability-of-success objective. The method uses fixed real spending: the initial withdrawal is adjusted for inflation in later years rather than reset to a fixed percentage of the account each year.
That framework answers a specific question: how large a diversified portfolio may need to be at the start of a 30-year drawdown to support an inflation-adjusted spending path under the model’s assumptions. It does not predict your returns, establish a safe rate for every asset mix or guarantee that a real account will finish with money.

- Ideal for a bookworm
- Compact for travelling
Morningstar’s detailed work also identifies the drawdown period, asset allocation and withdrawal cadence as material inputs. A person retiring at 50 may need to plan for substantially longer than 30 years. Someone with a shorter horizon may be able to spend at a higher rate under a comparable model, but the result still depends on the investments and sequence of returns.
Why retirement length can change the answer
A 30-year retirement
The 3.9% estimate is built around 30 years. It is most directly relevant to someone whose spending plan has a similar horizon and whose portfolio and other income resemble the modeled assumptions.
A longer horizon
An early retiree, or anyone planning for an uncertain lifespan, faces more years in which a bad return sequence or high inflation can damage the account. Extending the horizon generally calls for a lower starting rate, a larger initial balance, more flexible spending or a combination of the three. Morningstar’s February 18, 2026 summary does not establish one universal percentage for a 40-, 50- or 60-year retirement, so applying 3.9% unchanged to those horizons would overstate the evidence.
A shorter horizon
If the portfolio only needs to cover a shorter period and the owner is comfortable spending down principal, a higher initial rate may be workable in some models. That is a different objective from preserving a bequest or maintaining the same spending indefinitely.
“Generate” can mean two different things
Total-return withdrawals
The $2.94 million scenario uses a total-return approach. Interest and dividends may cover part of the cash need, and selling shares or bonds can cover the remainder. Selling assets is not automatically a failure: it is how a planned withdrawal strategy converts a portfolio into spending.
Interest-and-dividends only
If “generate” means receiving $9,550 every month without ever selling assets, the withdrawal-rate calculation is not the right formula. You would need a specified portfolio yield, the account’s tax treatment and a date for the yield observation. The required principal would be $114,600 ÷ stated annual yield, but the yield can change and higher-yielding assets can bring additional credit, interest-rate, equity or concentration risk.

Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Morningstar’s April 5, 2024 discussion used a basic 60/40 portfolio with an SEC yield of about 2.6% as a historical illustration. That was a dated example, not a current yield quote. It also noted that taxes in a taxable account would reduce the spendable amount. At a 2.6% gross yield, $114,600 divided by 0.026 would be about $4.41 million before tax, but that arithmetic is not a recommendation and does not establish what the same portfolio yields today.
Taxes and outside income can move the target
When $9,550 is a pretax withdrawal
If $9,550 is the amount taken from the portfolio before taxes, the $114,600 annual target is the correct input for the scenario calculation. The amount available for spending will be lower after federal, state and local taxes, depending on account type and the composition of withdrawals.
When $9,550 is the amount you want to spend
If the goal is $9,550 after tax, the portfolio may need to distribute more than $9,550 each month. The gross-up depends on taxable income, filing status, jurisdiction, deductions, whether withdrawals are from traditional or Roth accounts, and the share that represents basis or capital gains. The available information does not support one personalized after-tax balance.
When another income stream covers part of the budget
Subtract reliable outside income from the annual spending target before dividing by the withdrawal rate. For example, if a pension and Social Security together cover $40,000 a year, the portfolio target in the same framework would be based on $74,600 rather than $114,600. The resulting balance is only an illustration; benefits can be taxed, reduced, delayed or subject to survivor changes, so verify the actual payment and inflation adjustment.

Fixed spending versus flexible spending
Fixed, inflation-adjusted withdrawals provide a predictable spending path but expose the portfolio to sequence-of-returns risk. A large market decline early in retirement can leave fewer assets to participate in a recovery while the dollar withdrawal continues to rise with inflation.
Morningstar’s 2024 analysis found that flexible withdrawal methods can support higher initial withdrawals in some cases. The trade-off is less certainty about year-to-year spending and potentially a different ending balance. Flexibility might mean skipping an inflation increase after a down year, reducing discretionary travel, or applying a ceiling and floor to annual raises. A household whose essential bills are already covered by pensions or other income may find this easier than one that needs the portfolio to fund every expense.
Choose the method before retirement, write down the adjustment rules and distinguish essential expenses from discretionary ones. Otherwise, “flexibility” can become an unplanned reaction to market headlines.
A TIPS-ladder result is a different scenario
Morningstar’s 2024 report modeled a ladder of Treasury Inflation-Protected Securities at a 4.4% withdrawal rate with a 100% modeled probability of success at the time of publication. In that modeled strategy, the portfolio was liquidated by year 30. The result therefore describes a particular inflation-linked spending design and a willingness to use the principal over the full horizon; it is not a current TIPS yield, an offer to investors or a guarantee for a different ladder.

Withdrawal-rate estimates change with market assumptions
Morningstar’s published estimates have moved as capital-market assumptions changed:
| Research year | Reported starting estimate | Context |
|---|---|---|
| 2021 | 3.3% | Morningstar estimate using that year’s assumptions |
| 2022 | 3.8% | Morningstar estimate using that year’s assumptions |
| 2023 | 4.0% | Morningstar estimate using that year’s assumptions |
| 2024 | 3.7% | 2024 report; inputs dated September 30, 2024 |
| 2026 | 3.9% | Latest summary dated February 18, 2026 |
The changes show why a withdrawal rate is not a timeless constant. When quoting one, identify the publication date, horizon, spending rule and asset-allocation assumptions. Do not treat a rate from one year as a permanent market law.
A practical way to stress-test your own target
- Define the cash-flow number. Decide whether $9,550 is pretax portfolio withdrawals or after-tax spending. List irregular costs such as insurance premiums, property repairs and major travel separately.
- Subtract dependable income. Include only benefits and payments you can document, and account for survivor changes or delayed claiming decisions.
- Set the horizon. Use 30 years only if that is a reasonable planning period. Longer horizons need additional analysis.
- Select a spending rule. Compare a fixed inflation-adjusted withdrawal with at least one flexible rule that specifies when spending can rise or fall.
- Model taxes by account. Traditional, Roth and taxable withdrawals can produce different taxable income and cash results. Coordinate withdrawals with required minimum distributions and other tax events.
- Test poor early returns. The same average return can produce very different outcomes depending on whether losses occur in the first few years. Review what expenses would be cut if the portfolio falls.
- Revisit the plan. Recalculate after major changes in spending, health, benefits, portfolio mix, inflation or market conditions rather than assuming the original percentage remains suitable.
Common mistakes that make the estimate misleading
- Using a monthly rate as if it were annual. The calculation uses the annual target of $114,600 and an annual starting rate.
- Confusing a withdrawal rate with a yield. A portfolio can fund withdrawals by selling assets; distributions alone are a separate question.
- Ignoring taxes. A pretax withdrawal and an after-tax spending goal are not interchangeable.
- Assuming a 30-year result lasts forever. Early retirement and longevity uncertainty require a longer-horizon test.
- Changing the percentage every year without a rule. Decide whether withdrawals are fixed in real dollars or tied to the current balance before markets move.
- Chasing yield. A higher stated yield can come with greater risk and does not by itself make a spending plan safer.
- Treating modeled success as certainty. A 90% modeled probability still includes unsuccessful paths, and actual returns, inflation and behavior will differ from the model.
What to take to a planner or calculator
Bring a month-by-month spending estimate, account balances and tax basis, expected Social Security or pension statements, insurance costs, debt payments, charitable goals and a desired legacy. Ask for results under multiple horizons and withdrawal rules, not one “safe” number. Request the assumptions in writing: inflation, investment mix, fees, taxes, rebalancing, withdrawal timing and the definition of success.
A calculator can show how much the balance changes when the spending target, outside income or rate changes. It cannot turn an estimate into a guarantee. The purpose of the roughly $2.94 million figure is to provide a transparent starting point for that conversation, while the final target must reflect the household’s actual cash flows and tolerance for spending changes.
