coe.com.sg is an independent, non-commercial project. Everything on it is built from data the Land Transport Authority of Singapore publishes under the Open Data Licence, covering bidding results, quotas, deregistrations, and vehicle-population snapshots. We don’t collect our own numbers; we just chart theirs.
The brief was simple: the data is out there, so what does it look like when you actually chart it decade by decade, cross it against deregistrations and fleet population, and let people poke at it? The pages below are the answer so far.
Ten years of bidding results for each of Cat A to E, plus the last ten exercises at a glance.
How LTA turns deregistrations and fleet-stability targets into the quarterly quota that drives everything else.
Which makes registered the most vehicles in a given month, with per-brand detail pages across cars, goods, buses and motorcycles.
How Singapore’s vehicle mix has moved between petrol, diesel, hybrid and pure electric over the last decade.
A deliberately simple model that takes a guess at each upcoming exercise, with a track record showing how it would have done on every past exercise. You can also enter your own guess and see how you stack up.
What a COE is, how bidding works, what happens at 10 years, renewal costs. The articles we wished had existed when we started.
Nothing here is official. We aren’t affiliated with the LTA or any motor dealer. Numbers are refreshed from the LTA data.gov.sg feeds, so they lag real-world changes by whatever LTA’s own publishing cadence is.
The COE prediction model is a bit of fun, not financial advice. It’s a simple trailing-average-plus-nudges model and can be wildly off. If you’re about to make a six-figure bidding decision, please don’t do it because of a chart on this website.
