Renew COE vs Replace Car (Singapore, 2026)

Decision comparison · Last updated: February 2026

This decision is not “renewal is cheaper monthly”. It’s: what total exposure are you accepting for the next 5 years — and how much fragility you’re adding.

The clean decision rule

If you’re undecided after reading, run the numbers — the break-even usually reveals itself.

Decision table (fast)

Signal Leans toward Why it matters
Your usage is stable for 3–5 years Renew Renewal is a “commitment buyout”. Uncertainty is expensive.
Repair risk is rising / unpredictable Replace One major repair can erase the perceived renewal savings.
You want to reduce COE timing risk Renew You lock your structure and avoid buying into a bad COE moment.
You’re renewing because “selling now is painful” Replace Sunk cost bias. Don’t extend a mistake to avoid admitting it.
Cashflow looks fine but liquidity is thin Replace / downsize Fragility kills: the bad month forces a bad sale.

Run the numbers (recommended order)

  1. COE renewal worth-it framework (the base model)
  2. 5-year renewal vs 10-year renewal (structure choice)
  3. 5-year ownership exposure (so you compare like-for-like)
  4. Car affordability stress test (so you don’t become fragile)

Common failure mode

People renew COE to “avoid buying high” — then forget they are still buying a structure. If renewal pushes you into thin liquidity, you’re not safer — you’re more trapped. If this feels familiar, read the instalment trap.
