A worked example · sixth in the series, first outside the US
CPF fills first. Then equity takes over.
Every input here is Singaporean: CPF (Central Provident Fund) instead of a 401(k), an HDB resale flat instead of a mortgaged house, no car (only about 1 in 3 Singapore households own one). This version models the household's savings the way a real Singaporean family runs them - CPF as a fixed-income account that fills first, then a globally diversified equity fund for everything saved beyond it - and the children's cost ends when they finish their education, not at age 84. The two savings pools have opposite shapes: CPF (fixed income) builds early and is spent down first in retirement, while equity starts at zero, overtakes CPF around age 64, and keeps compounding to the end. The portfolio grows every single year of the 45-year plan.

Methodology
Modelling a real Singaporean savings scheme
Same discipline as every US profile - a named government or industry survey per figure, median over mean where both exist - but Singapore's retirement system doesn't map cleanly onto Dispono's model. Household income isn't published by age of household head, so this profile uses the latest overall median (SingStat). A Singapore payslip has two deductions before cash is spendable - income tax (~3.7%) and the employee's own mandatory 20% CPF contribution - so income-1 combines both into one ~24% rate, computed from IRAS's 2025 brackets for a two-earner household. The employer's own 17% CPF contribution (CPF Board's 2025 rate table, S$1,920/mo) is real money the household has, added as a separate, untaxed income line.
This version models three things the way the profile's owner specified, all within the real limits of Dispono's engine:
- CPF as fixed income, savings beyond it as equity. The target allocation is a 40% Fixed Income / 60% Equity split with annual rebalancing off. Because Dispono sizes each cohort's target against the whole portfolio - which counts the S$628,000 flat - the CPF fixed-income anchor starts below its 40% share and fills first; equity stays at S$0 until about 2034, then receives the bulk of new saving and compounds into the larger long-run pool. That reproduces the real Singaporean pattern: mandatory CPF dominates early-career saving, discretionary equity investing ramps up later once income has grown and the HDB loan has cleared.
- The children's cost ends when they finish school. The S$1,058/mo children's-education figure (SingStat HES 2023, married couples with a school-aged child) is now a bounded recurring cash flow that stops in mid-2037, when a representative youngest child reaches ~23 - Singapore's statutory parental maintenance runs to 21, extended for tertiary study, and all Singaporean males do 2 years of National Service before university.
- The mortgage. Singaporeans really do pay their HDB loan from CPF; Dispono pays it from the household's combined cashflow. The total-wealth outcome is identical either way - a dollar of mortgage is a dollar of net worth whichever account it leaves - so we keep it simple and note the difference here rather than distorting the numbers to force it.
Two honest limits, disclosed rather than hidden: Dispono routes total surplus by one portfolio-share target, so it can't send the employer-CPF dollar specifically to fixed income while sending take-home savings to equity - the split is by share, not by source. And a bounded cash flow isn't inflation-adjusted and drops out of the near-term Cash-pool / Liquidity / Flexibility gauges (which read the recurring budget only), though it's fully present in the projection and the assets-at-84 measure.
| Input | Value used | Source |
|---|---|---|
| Household income | S$11,297 / mo | SingStat, "Key Household Income Trends, 2025" - median monthly household income from work, 2024. Not published by age of household head. |
| Combined income tax + employee CPF rate | 24% | IRAS 2025 resident brackets (~3.7% effective, two earners) plus CPF Board's mandatory 20% employee contribution, below age 55 |

| Target allocation | 40% Fixed Income / 60% Equity | Set deliberately: CPF (fixed income) fills first as the mandatory anchor; savings beyond it go into a global equity fund. Rebalancing off, so the split emerges as a two-phase trajectory. |
| Children's education & tuition | S$1,058 / mo, ending 2037 | SingStat HES 2023 (youngest child 7-15). Ends when the youngest reaches ~23: statutory maintenance to 21, extended for tertiary study + 2 years' National Service. |

Outcome · Cashflow
The 2026 budget
Salary, the employer's CPF contribution and CPF interest come to exactly S$164,408 against a S$164,408 budget, with S$44,703 of surplus invested. The children's-education cost shows S$7,406 - only its first partial year (it starts mid-2026 and will end in 2037). On top of the S$27,348 HDB loan payment and the combined 24% tax-and-CPF deduction already taken off salary.

Projected annual income vs. expenses by category, age 40 → 84
Both bars climb for over two decades. Three milestones shape the working years: the children's cost ends in 2037 (freeing the whole S$1,058/mo for saving), the HDB loan clears in 2041 at age 55, and work stops in 2049 at 63. Four real years, in the same category detail as 2026:
- SalaryS$168,557
- Employer CPF contributionS$28,647
- InterestS$15,664
- DividendsS$3,078
- InvestingS$76,623
- TaxS$40,454
- MortgageS$27,348
- Groceries & foodS$21,217
- Transportation (no car)S$14,189
- Utilities & home insuranceS$8,206
- Healthcare (out-of-pocket)S$7,072
- Children's education (Jan–Jun, final)S$6,348
- HDB flat maintenance (S&CC)S$1,268
- DiscretionaryS$13,220
Dividends now appear in income (S$3,078) - the equity pool has started growing, the CPF-first phase handing off to the equity phase. From 2038 the children's cost is gone entirely.
- InterestS$35,690
- Withdraw InvestmentsS$31,229
- DividendsS$17,389
- Groceries & foodS$27,446
- Transportation (no car)S$18,355
- Utilities & home insuranceS$10,616
- Healthcare (out-of-pocket)S$9,149
- HDB flat maintenance (S&CC)S$1,641
- DiscretionaryS$17,101
A gap year - no salary, no CPF LIFE yet (starts 65). Interest off the CPF/fixed-income balance (which peaks this year at ~S$1.33M) plus equity dividends nearly cover the whole budget; only a modest withdrawal tops it up, and total net worth still grows. The mortgage cleared at 55 (2041, down to S$52), so housing is long behind them.
- CPF LIFE payoutS$47,897
- DividendsS$34,601
- InterestS$31,963
- Withdraw InvestmentsS$10,817
- Groceries & foodS$40,784
- Transportation (no car)S$27,275
- Utilities & home insuranceS$15,774
- Healthcare (out-of-pocket)S$13,595
- HDB flat maintenance (S&CC)S$2,438
- DiscretionaryS$25,411
At 84, CPF LIFE and equity dividends together cover most of the budget, with interest and a small withdrawal filling the rest. Income equals expenses exactly, as every year - the plan never comes up short.
Outcome · Investments
Two pools, opposite shapes
At 40, net worth is S$508,079 - more than double any US profile's start in this series, mostly because CPF is already a large, mandatory asset by this age. From here the portfolio grows every single year to S$4,536,116 at age 84 (its highest point ever), but the two savings pools move in opposite directions along the way.
- Real estate (HDB flat)S$628,000

Outcome · Analysis
What Dispono's risk analysis finds
Debt-to-income reads green ("Comfortable," 17%) because the employer's CPF contribution counts as real income. Assets at 84 reads "Unspent wealth" (36×) - the 60% equity sleeve compounds into a large terminal balance, and the children's cost ending in 2037 frees up even more to invest.
Net worth against essential expenses is already well past the "Ahead" threshold for this age - CPF makes the starting balance unusually large.
The one measure this profile doesn't beat the series on - S$5,000 of day-to-day cash (no official Singapore statistic to size it), against a large budget, doesn't stretch far.
The CPF balance alone counts as cash-and-bonds liquidity here, large enough to run past the top of the gauge.
Counting the employer's CPF contribution as the real income it is pulls the HDB-loan burden down to a comfortable 17%.
"Red" means the opposite of the US profiles' problem - not running out, but likely over-saving: the compounding equity sleeve leaves far more at 84 than this household will spend.
The lowest flexibility rating in the series - discretionary spending is a small share of a budget dominated by tax, CPF and a large mandatory investing line. (This gauge reads the recurring budget only, so the now-bounded children's cost no longer weighs on it.)
Income is still projected to outpace inflation comfortably for now.
Stress-testing the plan
Same five scenarios as every US profile. Nothing pushes the rating out of "Unspent wealth," but unlike the earlier all-fixed-income version of this profile, the equity sleeve now gives the plan real - if well-cushioned - market exposure.
| Scenario | What's stressed | Assets at 84 | Multiple | Rating |
|---|---|---|---|---|
| Baseline | Current plan, no changes | S$4,536,115 | 36× | |
| Lower returns | Expected return 5% → 3.5% for the full period | S$3,463,116 | 28× | |
| Higher inflation | Inflation 2% → 3% for the full period | S$4,672,740 | 24× | |
| Crash early | Equity −30% in year one (2026) | S$4,536,115 | 36× | |
| Crash mid-way | Equity −30% at age 65 (2051) | S$3,586,412 | 29× |
"Crash early" is byte-identical to Baseline - but for a real structural reason, not luck: in 2026 the equity position is still exactly zero (CPF fills first, so equity doesn't start growing until ~2034), and a −30% shock to nothing is nothing. "Crash mid-way" (2051) and "Lower returns" tell the real story: by then decades of saving have built a substantial equity pool, and both stresses knock a million-plus off the terminal balance. The plan absorbs it comfortably - but the exposure is genuine now, which is exactly what modelling those savings as equity, rather than fixed income, buys you: more growth, more market risk.
Key insights
What this profile actually tells you
Four findings from this model, each backed by the real Dispono output above.
Finding
CPF and equity are two pools with opposite shapes
Modelling CPF as fixed income and everything beyond it as equity produces a genuine two-phase plan: the CPF anchor fills first and peaks at S$1.33M around age 64, then is spent down first in retirement; equity starts at zero, overtakes CPF near 2050, and compounds to S$2.71M by 84. One pool is the safe base that funds the early retirement years; the other is the growth engine that finishes the job. Neither on its own tells the story.
Finding
Ending the children's cost is worth real money
A cost of children isn't forever. Modelling S$1,058/mo that stops in 2037 - when the youngest finishes tertiary study and National Service around age 23 - instead of running to age 84 frees up over a decade of that spending to compound in equity. It's a reminder that a realistic plan has to model when costs end, not just when they start.
Finding
The employer's CPF contribution is real, and it matters
At 17% of wages - S$23,040 in 2026 alone - the employer's CPF contribution is larger than most take-home-pay-based calculators ever see. Counting it as real income pulls debt-to-income from 20% to a comfortable 17% and adds a substantial stream that helps build both savings pools.
The limits of the model
One engine, one surplus, one target - disclosed, not hidden
Dispono routes total surplus by a single portfolio-share target, so it can't literally send the CPF dollar to fixed income while sending take-home savings to equity - the two-phase split is the closest faithful approximation, and the mortgage is paid from combined cashflow rather than drawn specifically from CPF (identical effect on total wealth). Every one of these limits is written into the profile's own model notes, the same discipline this whole series runs on.
Read the whole picture
Three numbers worth remembering
The average 40-year-old Singaporean starts with S$508,079 in net worth - more than double any US profile in this series, thanks to a mandatory CPF balance that's already substantial by this age. Modelled the way a real household runs it - CPF as fixed income filling first, then a global equity fund for everything saved beyond it, with the children's cost ending at their graduation - the plan grows every single year to S$4,536,116 at age 84, its highest point ever. The CPF pool peaks at S$1,331,230 around age 64 and funds the early retirement years; the equity pool, starting from zero, compounds past it to S$2,713,765 and becomes the household's largest asset. The tradeoff is real on both sides: less discretionary room today (the lowest Flexibility score in the series) and genuine market exposure in the equity sleeve, in exchange for a plan that never runs dry.
