Fast path:
In Singapore, depreciation is usually shorthand for how much value your car loses each year. Because COE dominates the cost structure, depreciation often becomes the single largest component of ownership cost — bigger than fuel, parking, or insurance for many drivers.
A practical estimate is:
This is not accounting math. It’s a decision tool. Your goal is to avoid underestimating your real monthly exposure.
When COE is high, you are effectively prepaying more of your usage upfront. If resale prices don’t rise at the same pace (or you sell at the wrong time), your depreciation spikes.
That’s why timing pages like buy now or wait matter — not because anyone can predict COE, but because your holding period and exit plan must be realistic.
If you’re deciding between the two, use used vs new and treat depreciation as the primary lever (not just monthly instalment).
COE renewal changes the depreciation story because the remaining usable life is reset, but your car’s age and maintenance profile don’t disappear. If you’re considering renewal, read:
Depreciation is how much value your car loses each year. In Singapore, it is heavily influenced by COE, remaining COE years, and prevailing market prices.
Because COE and scarcity-driven pricing compress most of the car’s cost into the ownership period. Over 5–10 years, depreciation/COE exposure often dominates fuel, insurance, and maintenance.
It’s a strong starting point, but you should evaluate total exposure: depreciation plus running costs (fuel, parking, ERP, insurance, maintenance) and your usage pattern.
