What a car costs a Singaporean household: about S$2.8 million.

Methodology

The real cost of an average Singapore car

Everything in this profile is copied verbatim from the no-car base household - income, CPF, the S$628,000 HDB flat and its loan, the children's cost, the 40% Fixed Income / 60% Equity target - so the only variable is the car. The base profile noted that only about 1-in-3 Singapore households own a car (the COE-driven car-lite policy); this is that 1-in-3 household. The single "Transportation (public transit)" line at S$951/mo is replaced by three car cost lines totalling about S$2,496/mo, built from published 2025 figures for a Toyota Corolla Altis 1.6L (Category A COE) - the archetypal Singapore mass-market family car.

• Depreciation — S$1,546/mo. An Altis costs about S$196,888 to drive away, which bundles the car's Open Market Value (OMV), the tiered Additional Registration Fee (ARF), the ~S$126,000 Category A COE and registration fees. At 10 years the COE expires worthless and the car is scrapped for its PARF rebate (~S$11,400). The ~S$185,000 consumed over the 10-year COE life is S$1,546/mo - by far the biggest cost of car ownership here, and the reason cars are so much dearer in Singapore than almost anywhere else.
• Road tax, insurance, servicing & repairs — S$270/mo. Road tax S$742/yr (LTA, 1.6L engine), motor insurance ~S$1,500/yr, and servicing plus a repair reserve ~S$1,000/yr.
• Fuel, ERP & parking for the daily commute — S$680/mo. Petrol S$300/mo (~50 km/day), ERP S$120/mo (a daily peak-hour commute crossing expressway gantries morning and evening), and parking S$260/mo (HDB season parking at home plus workplace parking near the office). Per the brief, these three reflect the daily commute specifically.

One modelling choice, disclosed: Dispono has no depreciating-asset mechanism, and a Singapore car's COE expires worthless at 10 years, so the car is modelled as its ongoing cost of ownership - the standard way Singapore car costs are quoted - rather than as a balance-sheet asset. The cost is assumed to run for the whole plan (the household keeps owning and replacing a car, even in retirement); a real retiree might give the car up, which would soften the later years.

Outcome · Cashflow

The 2026 budget

Income is identical to the no-car household - S$164,408. But the car takes S$29,952 this year (depreciation S$18,552 + the commute's fuel/ERP/parking S$8,160 + road tax/insurance/servicing S$3,240), against S$11,412 for public transit in the base. That extra ~S$18,500 comes straight out of investing, which drops to S$26,163 (from S$44,703 without the car).

The car's three brown lines never go away, and depreciation grows with inflation, so the car's claim on the budget only rises. By retirement it dominates. Four real years:

At 84, the car's three lines add up to S$71,587 - about 42% of the entire S$169,589 budget. A retiree still paying to depreciate, insure, fuel and park a car is spending more on the car than on food, housing and healthcare combined. Every year's income still equals expenses exactly - but from 2050 on, only because the household is drawing steadily on savings the car should never have consumed.

Outcome · Investments

The car drains the CPF pool to zero

The no-car household's portfolio grows every single year to S$4.54M and never depletes. With a car, the same portfolio peaks at S$2,458,648 in 2050 (age 64) and then declines to S$1,718,138 by 84 - and the CPF fixed-income pool, drawn on first, is emptied completely by 2065.

Outcome · Analysis

What Dispono's risk analysis finds

The car pulls "Assets at 84" down from the no-car household's 36× ("Unspent wealth") to 10× ("High") - still healthy, but the entire margin is gone. The near-term gauges reflect today's holdings, so they move only a little; the car's real damage is a long-run, compounding effect the projection makes visible.

Stress-testing the plan

With the margin gone, the stresses bite harder than they do for the no-car household. A single point of extra inflation is now enough to push the plan into "Thin."

"Crash early" still equals Baseline (equity is S$0 in 2026, so a shock hits nothing). But "Higher inflation" now lands on "Thin" (4.6×) - because the car cost inflates too, and a car whose price keeps rising through a 45-year retirement is a compounding drag the no-car household simply doesn't carry.

The comparison

Same household, one car, S$2.8 million

Because this profile changes nothing but the transport line, the gap between it and the no-car base is a clean measure of what a car costs a Singaporean household over a lifetime.

A S$1,545/mo difference in one budget line, compounded over 45 years and the growth it would have earned, is worth about S$2.8 million at 84. That is the true price of the car - many times its S$196,888 sticker, because in Singapore you buy a new one roughly every ten years, and every dollar spent on it is a dollar that never compounds.

Three numbers worth remembering

The average 40-year-old Singaporean household starts with S$508,079 in net worth either way. Give them a car - an average Toyota Corolla Altis, at about S$2,496/mo all-in once you count COE, ARF, depreciation, road tax, insurance, servicing, fuel, ERP and parking for the daily commute - and the plan changes shape entirely: net worth peaks at S$2,458,648 around age 64 and falls to S$1,718,138 by 84, the CPF pool is drained to zero by 2065, and "Assets at 84" drops from 36× to 10×. The car costs this household about S$2.8 million over a lifetime, many times its sticker price. In Singapore, owning a car is one of the biggest retirement decisions a household makes - and it rarely feels like one.
