Find what the portfolio must pay.
Subtract other income from spending on a consistent after-tax basis, allowing for extra tax and charges on obtaining portfolio money. Include irregular bills, plausible extra needs and spending currency; label today’s purchasing power versus future money.
Separate essential costs from amounts you could reduce or postpone. The gap changes when work stops, a pension starts or a bill arrives. Regular dividends do not establish lifetime spending capacity.
Other income and exchanging capital for a contract
Record income start dates, terms and uncertainty; rent, pension entitlements and temporary work have different dependencies. Check what continues after a partner’s death or inability to work.
MoneyHelper describes UK annuity examples: capital exchanged for contractual income for life or a fixed term. This differs from withdrawals from investments.
Examine insurer risk, applicable protection, inflation, survivor payments and capital access. Choices can be difficult or impossible to reverse; country availability and rules vary. An annuity is an option, not a required purchase.
A payout can accompany a loss.
Invented €100,000 opening portfolio. Holdings end at €92,000 after €3,000 is distributed. Distributions stay as cash until year-end. No other cash flows; ignore fees, tax and inflation.
€92,000 + €3,000 = €95,000 before spending: an investment loss of €5,000.
Inside the portfolio
Before the sale
Holdings€92,000
Distribution cash€3,000
Total €95,000
Sell €2,000 of holdings → add €2,000 to cash.
The money stays inside the portfolio.
After the sale
Holdings€90,000
Cash: €3,000 + €2,000€5,000
Total still €95,000
After paying the bill: €90,000 holdings + €0 cash
€5,000 leaves the portfolio
€3,000 distributions + €2,000 sale proceeds
One bill uses both sources. The remaining capital is €90,000.
Distributions belong to portfolio-funded spending. Counting them as independent outside income understates the total drawn from investments. A higher payout alone cannot establish sustainability; examine total return, concentration, costs and taxes.
This establishes no universal preference for sales over income. Decide affordable spending separately from whichever payout arrives.
Which amount does the rule update?
- Inflation-adjusted starting amount
- Begins with a share of initial capital, then adjusts that currency amount. It can demand a larger share of depleted capital.
- Percentage of current balance
- Changes spending with capital; a cut can leave essential bills unfunded even while money remains.
The conventional 4% rule uses the first approach. Neither rule establishes an appropriate personal withdrawal or promises that money lasts.
Compare formulas and their assumptions
Arithmetic illustration, not recommended withdrawals. Assume a 3% inflation adjustment to the first amount. The current €350,000 balance is a separate premise, not an investment path: €400,000 × 4% = €16,000 initially; €16,000 × 1.03 = €16,480 next year. Taking 4% of €350,000 instead gives €14,000.
Conventional evidence uses historical US assets. Specify duration, mix, inflation, fees, taxes and desired ending capital; historical or simulated outcomes depend on data and assumptions. An average lifespan is no personal deadline for needing money. The optional withdrawal section examines these limits further.
How much could actually be cut, and for how long?
A holiday can move; rent or care may not. A rule requiring unacceptable cuts is unsuitable, and a spending floor creates no funding. Higher nominal capital alone cannot justify permanently higher spending.
Coordinate actual withdrawals with allocation, access and payment dates. Review when income starts or ends, costs change materially or remaining capital no longer supports the assumptions. Distributions or sales can help rebalance, but payment cannot depend on an ideal trade happening first.
Get help with a specific consequential choice.
Essential investment-funded bills, irreversible pension choices, cross-country tax or inheritance, and difficult administration can warrant personalised help. Bring goals, spending, income, accounts and unresolved decisions.
A restricted product range may exclude relevant options; ask what the comparison covers.
Specify the question: can money arrive before the bill, what net amount is available, or what authority is needed? Use the earlier service-verification record to establish the relevant permissions, scope and payments. MoneyHelper’s procedures are UK guidance; advice does not remove investment uncertainty.
Revise the plan after income and capital fall
In a new fictional case, an immediate market fall takes €54,000 of holdings down 20% to €43,200. Accessible cash remains €6,000. This is all the capital; the cash already includes €5,000 assigned to a mandatory bill at the end of month 4. There are no other reserves or accounts.
For months 1–4, income is €1,800/month and non-investment expenses are €2,200/month. A separate €200 recurring investment transfer can be stopped before its first payment. The expenses include a genuinely reducible €150/month discretionary amount for all four months. Ordinary income and expenses occur before the end-month-4 bill.
Prices stay constant after the fall; ignore interest, further returns, FX, fees and tax. Sale proceeds can fund the bill only if settlement and withdrawal arrive before it; those dates are unconfirmed.
Write a four-month funding calendar and revision note comparing (A) pausing transfers only and (B) also making the spending cut. Show any missing cash, the conditional sale route, what changes in the goal/contribution/maintenance record and the next check. Do not invent a new optimal target.
Two worked calendars and revision checks
Opening position: €54,000 holdings × 0.80 = €43,200 holdings, plus €6,000 accessible cash. That cash already includes the €5,000 bill assignment; there is no other reserve.
A · Pause transfers, keep spending unchanged
€1,800 income − €2,200 non-investment spending = €400 monthly cash gap. Pausing the separate €200 investment transfer stops an outflow; it creates no income.
- Start: €6,000 cashStop the investment transfer before month 1.
- Months 1 → 2 → 3 → 4After ordinary spending: €5,600 → €5,200 → €4,800 → €4,400 cash.
- End month 4: €5,000 bill due€4,400 cash → €600 missing.
B · Pause transfers and actually cut €150 each month
Spending falls to €2,050. Income €1,800 leaves a €250 monthly gap for all four months.
- Start: the same €6,000 cashThis is an alternative to A, not extra money.
- Months 1 → 2 → 3 → 4After ordinary spending: €5,750 → €5,500 → €5,250 → €5,000 cash.
- End month 4: pay €5,000 bill€0 cash + €43,200 holdings. No sale is required on these assumptions.
Both routes exhaust cash. Four months of cutting €150 saves €600, exactly A's shortfall. Neither calendar establishes funding after month 4 or sustainable lifelong spending.
- Changed obligation
- Lower income and a fixed bill now compete for the same cash; the old contribution instruction is unaffordable.
- Funding revision
- Pause €200 before the first transfer. A still lacks €600; B closes this window only if all four spending cuts occur.
- Open action
- Obtain settlement and withdrawal terms early enough to test cash arrival before the bill; prepare another feasible funding change if A cannot settle in time.
- Strategy / maintenance
- A may consume long-term capital; the new fixed need warrants reviewing its role and access. A reset to old weights does not fund the shortfall or establish a new suitable target.
- Next check
- Check the revised budget before the first transfer, actual spending each month and the bill's funded route before its deadline. Plan the next cash period because no buffer remains.
This note revises one situation. The final practice brings the whole path together: goals, feasibility, exposure, ownership, work and what happens when assumptions change.
