COE renewal is not a paperwork decision. It is a capital allocation + reliability risk decision. The correct question is: Will the renewed car produce a lower true monthly cost (with acceptable reliability) than switching?
Renewal cost is PQP-based and category/cycle dependent. The framework below stays valid even when the number changes. If your renewal is specifically 5-year, use: 5-Year COE Renewal: Is It Worth It?

If your question is actually “should I own a car at all?”, start here: Is It Worth Owning a Car in Singapore?
Anchor “true monthly cost” properly here (not instalment thinking): True Monthly Cost of Owning a Car · COE cost engine: COE Cost in Singapore
Gate A — Holding period (the #1 decider)
Gate B — Reliability phase (repair volatility)
Gate C — True monthly comparison (renew vs switch)
You don’t need precision. You need a clean frame:
Renewal monthly exposure (rough) =
Renewal becomes rational when: renewal monthly exposure < switching monthly exposure, and reliability risk is acceptable.
This table is not “full monthly cost”. It shows why holding period matters. You still add insurance, fuel, parking/ERP, maintenance, and a repair buffer.
| Renewal cost | Hold 2 years (24m) | Hold 3 years (36m) | Hold 5 years (60m) |
|---|---|---|---|
| $40,000 | ~$1,667/m | ~$1,111/m | ~$667/m |
| $60,000 | ~$2,500/m | ~$1,667/m | ~$1,000/m |
| $80,000 | ~$3,333/m | ~$2,222/m | ~$1,333/m |
If this table already puts you in “stress zone” before adding running costs, renewal is usually not the move.
The common mistake: “Renewal lump sum vs new car instalment.”
The correct comparison: total multi-year exposure.
| Option | What you are paying for | Main risk |
|---|---|---|
| Renew COE | Amortising renewal cost over your holding period | Repair volatility + downtime |
| Switch car | Fresh depreciation curve + possible financing | Higher depreciation + financing drag |
Your decision is choosing between: repair volatility vs depreciation drag.

Renewal works best when: you know the car’s history and it is in a stable mechanical phase. If you depend on the car for tight family logistics, volatility is not “just money” — it’s disruption.
If you’re leaning “renew”:
If you’re leaning “switch”:
If you’re unsure:
Usually yes when the car is stable and you can hold long enough to amortise renewal cost. Usually no when repair risk is rising or holding period is uncertain.
Sometimes. Renewal can reduce depreciation drag, but increases repair volatility risk. The right answer depends on holding period and reliability.
Renewing without long holding commitment, or renewing while the car is entering escalating mechanical decline.
