- Pension entitlements and invested account balances are different planning inputs.
- Tax, contribution, portability, and access rules depend on the jurisdiction and scheme.
- The same returns in a different order can produce different outcomes when withdrawing.
Retirement planning starts with the income you can rely on, the assets you control, and the rules governing access. An account name does not answer all three questions. Public pensions, workplace schemes, mandatory savings arrangements, and voluntary investments can play different roles across countries.
Compare the promise, not just the account label
The OECD’s comparison of pension systems distinguishes several forms of retirement provision, including defined-benefit and defined-contribution arrangements. Its coverage includes Asian and Pacific economies; it is a comparison framework, not an account-opening guide for every country.
In a defined-benefit arrangement, a formula determines benefits, subject to the scheme’s rules. In a funded defined-contribution arrangement, contributions accumulate in an invested balance, and investment outcomes affect what is available. A projected balance and an entitlement to periodic income are different planning inputs.
Ask what the arrangement promises, which risks you bear, whether benefits change with prices, and who provides the income. Do not assume that a public or employer-linked scheme works like a personal investment account.
Separate the wrapper from the holdings
Where an account holds investments, its contribution, tax, and withdrawal rules are one layer; its holdings, fees, and market risks are another. Two accounts holding the same fund may face similar market movements while having different access rules. Two accounts with the same legal label can hold very different portfolios.
Eligibility, employer contributions, vesting, portability, and treatment after a change of tax residence require the actual scheme documents and current local guidance. No universal tax deduction, contribution limit, retirement age, or unrestricted withdrawal right applies to this comparison.
The order of returns matters when withdrawing
Consider two hypothetical portfolios starting with 100,000 currency units. Each withdraws 10,000 at the start of each year. One experiences a 20% loss followed by a 25% gain; the other experiences the same returns in reverse order. There are no fees, taxes, inflation, or further cash flows.
| Path | After first withdrawal and return | After second withdrawal and return |
|---|---|---|
| Loss first | (100,000 − 10,000) × 0.80 = 72,000 | (72,000 − 10,000) × 1.25 = 77,500 |
| Gain first | (100,000 − 10,000) × 1.25 = 112,500 | (112,500 − 10,000) × 0.80 = 82,000 |
Without withdrawals, both end at 100,000: 0.80 × 1.25 = 1. With these withdrawals, the final balances differ by 4,500. An early loss leaves less capital participating in the subsequent recovery. This arithmetic illustrates sequence-of-returns risk; it does not establish a safe withdrawal rate or predict retirement outcomes.
A plan therefore needs to examine the timing of spending, reliable income, and the ability to adjust withdrawals, alongside diversification and inflation. The Investor IQ scenarios tests reasoning about these trade-offs.
Translate the plan into usable income
A compounding calculation explores accumulation under a fixed assumption. It does not calculate pension entitlements, taxes, eligibility, or income from selling investments in a falling market. A future balance should be assessed against expected spending in the currency in which that spending occurs.
Build a comparison with four columns: expected income, investment exposure, costs, and access conditions. Record each source and date. That makes unresolved local rules visible before a smooth growth curve is mistaken for a complete retirement plan.
