Moving from accumulation to de-accumulation means changing the job of your portfolio from mainly growing capital to funding spending. The safest transition is usually planned: map income needs, hold enough low-volatility cash, control withdrawals and keep the portfolio diversified.

Start by writing down the spending your investments need to cover, then compare that figure with guaranteed income and the withdrawal rules of each pension or investment account.

Accumulation and de-accumulation are different jobs

During accumulation, the main question is how much you can save and how your investments can grow over time. During de-accumulation, the problem changes: you need cash for spending while protecting the portfolio from being damaged by poor returns, high fees and withdrawals that are too large to sustain.

That does not mean you should stop investing when you retire. It means the portfolio now has to serve two purposes at once: supply near-term cash and preserve purchasing power for later years. A portfolio that is entirely growth-focused can be uncomfortable to live from, while a portfolio that is entirely cash may lose ground to inflation over a long retirement.

Start with spending, not a withdrawal percentage

A common mistake is to start with a rule such as 'I will withdraw X% every year' and then see whether the household can live on it. A better starting point is the spending requirement. Separate essential costs from optional spending, then identify which costs are covered by salary, State Pension, Social Security, annuity income or other reliable sources.

Once you know the gap, you can work backwards to the portfolio. MoneyHelper's budgeting guidance is useful here, while FCA retirement-income information shows how people use drawdown, annuities and other retirement products. The plan should be reviewed rather than set once and forgotten.

Why the order of returns matters

Two investors can have the same average investment return but very different outcomes if one experiences a large fall near the start of retirement while the other experiences the fall much later. Withdrawals during an early market decline mean fewer remaining units or shares are available to participate when markets recover.

This is often called sequence-of-returns risk. One way to manage it is to hold a cash reserve for near-term spending and avoid selling the same proportion of growth assets in every market condition. The reserve does not remove investment risk, but it can reduce the pressure to sell risk assets after a sharp fall.

A cash bucket can make withdrawals more manageable

A simple structure is to keep near-term spending in cash or other low-volatility assets, while the rest of the portfolio remains diversified for longer-term needs. The number of years to hold in cash should be a planning decision, not a universal rule. The right amount depends on how flexible your spending is and how much guaranteed income you have.

The key is to decide in advance how the cash bucket will be replenished. In strong markets, you might top it back up by selling some investments. In weak markets, you might let the cash run down for a while and delay discretionary spending instead of automatically selling after the fall.

UK pension drawdown: tax still matters

In the UK, flexi-access drawdown allows flexible withdrawals, but withdrawals are generally taxable as pension income. HMRC's pensions guidance says a person can take as much or as little as they like from a flexi-access drawdown fund, subject to the tax rules.

The timing of withdrawals can therefore matter as much as the investment decision. A large withdrawal in one tax year may create a bigger tax bill than the same overall spending spread across several years, depending on your other income and allowances. Pension providers also have PAYE withholding responsibilities, so the amount you receive can differ from the amount you request.

US retirement accounts have their own withdrawal rules

For US readers, traditional IRAs and many workplace retirement plans have required minimum distribution rules. The IRS says required minimum distributions generally begin at age 73. Roth IRAs are treated differently for an original owner while alive, so US retirement planning should be account-specific rather than based on a single withdrawal rule.

The broader planning principle remains the same: work out spending needs, identify taxable and tax-free sources, and decide which account to draw from first. The order can affect taxes, investment risk and how long each account lasts.

Set a review cycle

A de-accumulation plan should be monitored. At least once a year, review the portfolio value, spending, guaranteed income, cash reserve, tax position and upcoming large costs. A major market fall or change in household circumstances is a reason to review sooner.

Do not measure success only by whether the portfolio is still larger than it was at retirement. The point of de-accumulation is to fund life while managing the risk of running out of money. A plan that spends too little out of fear can fail its purpose just as a plan that spends too much.

Common de-accumulation mistakes

Selling the same percentage of every asset every month regardless of market conditions.
Ignoring tax differences between pensions, ISAs, taxable investment accounts and US retirement accounts.
Keeping the entire retirement portfolio in cash because withdrawals feel safer that way.
Having no plan for one-off spending such as a car, home repair, care costs or family support.
Never reviewing the withdrawal plan after markets, tax rules or household spending change.

Illustrative sequence-of-returns example

Worked example

Illustrative sequence-risk example: Two retirees each start with £300,000 invested and plan to withdraw £18,000 for spending. Ignore fees and tax so the example focuses only on order of returns.

Bad first year: a 10% fall takes the portfolio from £300,000 to £270,000, then the £18,000 withdrawal leaves £252,000.
Good first year: a 10% rise takes £300,000 to £330,000, then the same £18,000 withdrawal leaves £312,000.

The two investors started with the same amount and took the same cash withdrawal. The difference is the sequence of returns. In real life, returns, inflation, taxes, investment charges and changing withdrawals all matter, so this is an illustrative explanation rather than a forecast.

What does de-accumulation mean for an investment portfolio?#

De-accumulation is the stage when you are using an investment portfolio to fund spending rather than mainly adding money to it. The challenge becomes balancing current income needs against the risk of selling too much after poor markets and leaving too little capital to support later years.

When should I switch from growth investing to income investing?#

There is rarely a single switch date. Many people keep a diversified mix of growth and defensive assets while gradually increasing the part of the portfolio intended for near-term spending. The right mix depends on spending needs, other income, time horizon and how much market risk you can tolerate.

How much cash should I keep in retirement?#

There is no universal number of years that works for everyone. Base the cash reserve on essential spending, guaranteed income, the flexibility of your discretionary spending and the rest of your portfolio. The goal is to reduce forced selling in a market fall, not to eliminate investment risk altogether.

Is it better to withdraw a fixed amount or a percentage?#

A fixed amount gives more predictable spending but can become aggressive after a major market fall unless reviewed. A percentage automatically adjusts to the portfolio value but can produce uneven income. Many plans use a spending target with rules for when withdrawals are increased, reduced or paused.

Are pension drawdown withdrawals taxable in the UK?#

Generally yes. HMRC treats flexi-access drawdown withdrawals as pension income, so taxable amounts are normally subject to Income Tax. The tax outcome depends on the amount withdrawn and your other income for the tax year, and PAYE withholding can affect the amount initially paid to you.

When do required minimum distributions start in the US?#

For many traditional IRAs and workplace retirement plans, the IRS says required minimum distributions generally begin at age 73. The exact required beginning date depends on the type of account and whether you are still working, so US withdrawals should be checked against the specific plan rules.

How do I protect a portfolio from a bad first year of retirement?#

Reduce the chance of forced selling by matching near-term spending to cash or lower-volatility assets, keeping the rest diversified, and setting clear rules for discretionary spending when markets fall. No method guarantees a smooth path, but planning the first few years can make a large difference to the portfolio's resilience.
