Invest with a goal in mind.

Understand the assumptions between today’s contributions and tomorrow’s spending.

About 22 min with exercises8 questions9-page workbook

By the end, you can

  • Connect risk and access to the date money is needed.
  • Distinguish nominal, real and after-cost returns.
  • Understand retirement timing and the limits of projections.

01 / Understand

The essentials

Start with the job the money must do

The time until a goal matters alongside your willingness and ability to absorb loss. Money needed soon and long-term retirement capital have different constraints. Write down the date, amount and currency of the goal before adjusting return assumptions. A higher assumed return cannot make an unaffordable contribution affordable.

A wrapper is not an investment mix

A pension or retirement account is a legal/product wrapper. Its underlying assets might be shares, bonds or cash. Similarly, an ETF is a fund structure, not a guarantee of broad diversification. Review what is inside, concentration, fees and restrictions; two accounts holding the same fund are still exposed to that fund.

Use one set of units

Nominal returns include the effect of changing prices; real returns describe purchasing-power growth. The exact relationship is (1 + nominal return) ÷ (1 + inflation) − 1. Keep spending and return assumptions consistent. Fees and taxes can reduce the amount retained, but their treatment depends on the product and jurisdiction.

02 / Apply

Put it into practice

1. Separate net worth from retirement funding

List accessible investments, restricted pensions and property separately. State pension is future income, not a pot that can be withdrawn today. Confirm when each account or benefit can be accessed. A large future pension does not pay bills during an earlier retirement bridge.

2. State contribution and withdrawal timing

In the Playbook’s illustrated monthly models, growth happens during the month and contributions or withdrawals occur at month end. Use an effective monthly investment rate consistent with the annual assumption. A future lump sum starts on its arrival date, not today.

3. Compare adverse paths, not only averages

With withdrawals, poor returns early in retirement can cause lasting damage even if later returns improve. Test lower returns, later lump sums, higher spending and a longer horizon. A deterministic chart does not provide a probability of success or a guaranteed safe withdrawal rate.

03 / Work it out

Same returns, different retirement outcome

Two fictional portfolios each start at €100,000. A €10,000 withdrawal is made at the end of each year. Both experience one +20% year and one −20% year. No fees or taxes are included.

PathAfter year 1After year 2
A: +20%, then −20%€100,000 × 1.20 − €10,000 = €110,000€110,000 × 0.80 − €10,000 = €78,000
B: −20%, then +20%€100,000 × 0.80 − €10,000 = €70,000€70,000 × 1.20 − €10,000 = €74,000
Same two annual returns; €4,000 difference after withdrawals

Without withdrawals, both sequences would finish at €96,000: €100,000 × 1.20 × 0.80. With withdrawals, the order matters. Selling or withdrawing from a smaller pot after the early loss leaves less capital to participate in the recovery.

Your turn

Try it: nominal return is 5% and inflation is 2%. What is the real return, before other costs?

Show the worked answer

1.05 ÷ 1.02 − 1 = 0.0294118, or approximately 2.94%. Subtracting 2% from 5% gives a rough approximation, not the exact result.

04 / Check the gaps

Before you decide

Counting home equity and future sale proceeds twice

If an asset is included in the current pot, adding its full future sale proceeds can duplicate funding. Treat the sale as a conversion of an existing asset or exclude the overlapping initial value.

Reading volatility as the maximum possible loss

A standard deviation or normal-distribution loss metric is an assumption-based summary. Extreme losses, leverage, illiquidity and changing correlations can fall outside that picture.

Calling 4% universally safe

A withdrawal percentage is a scenario input. Horizon, market sequence, costs, taxes, other income and flexibility affect whether the plan lasts.

05 / Make it yours

Your working notes

Use these prompts in the PDF workbook or your own notes. Keep sensitive records in an appropriate secure location.

  1. Goal amount, spending currency and first withdrawal date
  2. Accessible assets versus restricted accounts and property
  3. Contribution amounts and dates; fees and tax assumptions
  4. Nominal or real return basis and matching spending basis
  5. Pension start dates, future lump sums and adverse scenarios

Before moving on

  • I know the underlying investments, not just account names.
  • Returns, inflation and spending use consistent units.
  • Future funding does not conceal an earlier shortfall.
  • I understand that scenarios are not promises.
