In the second July bidding exercise, a Singapore Category A Certificate of Entitlement closed at S$126,000. That is a permit. It buys no metal, no engine, no warranty. It is the right to put a car on the road for ten years, after which it is worth nothing.

At the end of July a Singapore dollar bought RM3.18, which makes that permit RM 400,730. A new Perodua Myvi 1.5 X is RM 50,900 on the road.

The licence costs roughly eight times the entire car.

The average Category A COE premium by year from LTA's bidding data: 29,906 Singapore dollars in 2019, 35,403 in 2020, 47,424 in 2021, 75,808 in 2022, 94,537 in 2023, 90,494 in 2024, 102,912 in 2025 and 117,094 in 2026 to July. That is 3.9 times higher in seven years.
3.9× in seven years — and none of it buys any part of a car

Averaged across each year's exercises, Category A has gone from S$29,906 in 2019 to S$117,094 so far in 2026. The all-time high, S$129,000, was set this month. The all-time low was S$18,502, in January 2010.

Two countries that tax completely different things

Most people know Singapore is "more expensive" and Malaysia is "cheaper". But the totals hide the shape of the costs, and that shape determines which car is the better buy.

Singapore taxes owning a car at all. The COE is the same whether you buy a small hatchback or a well-equipped saloon inside the same category. It is a quota system, so the price is set by how many other people want one this fortnight.

Malaysia taxes engine size, steeply. Road tax is flat up to 1600cc and then climbs on a per-cc scale that gets brutal at the top. Look at what that does to the comparison:

1.0 litreRM 20 a year in Malaysia. S$391 in Singapore — about RM 1,244. Singapore charges 62 times as much.
1.5 litre (a Myvi)RM 90 against S$682, or roughly RM 2,169. Still 24 times.
2.0 litreRM 379 against S$1,210 — about RM 3,848. Down to 10 times.
3.0 litreRM 2,120 against S$2,380, or about RM 7,571. Only 3.6 times.

The gap collapses as engines grow. By three litres, Malaysia's steep scale brings its road tax almost level with Singapore's; the real punishment in Singapore is reserved for small cars.

There is one number in the Malaysian scale worth memorising if you are buying there. Road tax is RM90 flat at 1600cc, and at 1601cc it jumps to a RM200 base plus 40 sen for every cc above 1600. A single extra cubic centimetre more than doubles the bill, and it keeps climbing from there. That cliff is a large part of why so much of what sells in Malaysia is exactly 1.5 or 1.6 litres.

The February change that made Singapore cars quietly worse

Singapore's system gives you money back when you deregister: a COE rebate for the unused months, and a PARF rebate that returns part of the Additional Registration Fee you paid at the start. These rebates give a Singapore car a computable residual value, not just a guessed-at resale price.

In February 2026 the PARF half of that was cut roughly in half.

Three PARF rebate schedules run in parallel. For COEs before the second February 2023 bidding: 75 percent of ARF at five years falling to 50 percent at ten, no cap. For February 2023 to the first February 2026 bidding: the same percentages, capped at 60,000 dollars. From the second February 2026 bidding: 30 percent at five years falling to 5 percent at ten, capped at 30,000 dollars.
Three schedules, all live, and the one you get depends on your COE date

Take a mass-market car with an Open Market Value of S$25,000. The ARF on that is S$27,000 — the first S$20,000 of OMV at 100%, the next S$5,000 at 140%. Deregister at exactly five years:

  • If you bought in January 2026, PARF returns 75% of ARF: S$20,250.
  • If you buy today, PARF returns 30%: S$8,100.

The COE rebate is identical in both cases and unchanged by the reform. The difference is S$12,150 on the same car at the same age. On expensive cars the damage is worse: the rebate cap fell from S$60,000 to S$30,000, so any car with an ARF over S$100,000 loses another S$30,000 outright.

LTA's stated reason, in its own words, is that "EVs are less pollutive than conventional petrol cars. As EVs become more commonplace, the need to encourage early deregistration through the PARF rebate is reduced." It's a coherent policy, but it's also a large, retroactive-feeling change to the economics of a ten-year purchase. If you last bought a car before February, the numbers in your head are wrong.

Note what this does to the shape of Singapore depreciation. Don't model a Singapore car's value as a sagging curve. It is a ten-year asset with a computable floor, and at exactly 120 months both rebates go to zero together. Every generic car-depreciation model, including the one we shipped until this week, gets that wrong.

Malaysia now has two prices for the same petrol

Since 30 September 2025, RON95 has had a subsidised price for eligible Malaysians under BUDI95 and a floating unsubsidised one for everyone else. For the week of 30 July to 5 August 2026, in Peninsular Malaysia:

RON95, subsidisedRM1.99 a litre — the headline figure, held flat.
RON95, unsubsidisedRM3.82 a litre. Same fuel, same pump, 92% more.
RON97RM4.40 a litre, floating weekly.
DieselRM4.62 a litre at the market price.

Fifteen thousand kilometres a year at 6.5 L/100km is 975 litres. That is RM 1,940 a year subsidised, RM 3,724 unsubsidised — a difference of nearly RM 1,800 for identical driving.

And the subsidised price is quota'd, reported at 300 litres a month with a cut to 200 under discussion. A Malaysian driver's fuel cost isn't a single price. It's a two-tiered rate with a monthly quota, so your final bill depends on your eligibility and your mileage.

We are not putting a figure on Singapore pump petrol. Listed prices for 95 differ sharply between sources on the same day, and Singapore retailers discount 20–24% through loyalty and credit-card combinations, so the listed price is not what anyone actually pays. A number here would look authoritative and be wrong.

How to work out your own figure

Our total cost of ownership calculator now computes road tax from the published scales. Pick a market and an engine size, and it adds the correct figure, in the right currency, to your running costs. Pair it with the car loan calculator if you are borrowing, since the calculator deliberately excludes financing interest, and the fuel economy calculator to turn your actual mileage into litres before you apply either of Malaysia's two prices.

For Singapore, one modelling note that matters more than any of them. Put the COE inside the purchase price, and the PARF plus COE rebate inside the resale value. The tool will then be doing arithmetic that matches the market. Be careful not to take a "resale value" from used-car ads. Those prices already include the remaining COE, so you would be counting it twice.

What to actually do

In Malaysia, watch the 1600cc line — one cc over doubles your road tax, and the scale keeps climbing. Check your BUDI95 eligibility and your monthly litres, because the difference between the two RON95 prices is nearly RM1,800 a year on ordinary mileage. In Singapore, find out which PARF schedule your car is on before you assume anything about what you will get back; if your COE dates from the second February 2026 bidding or later, halve whatever figure you had in your head. Model a Singapore car as a ten-year asset, not a depreciation curve. And compare the road tax before the engine: the two countries disagree so completely about what to tax that the sensible car in one is the expensive one in the other.

What this audit found in our own tools

This guide began, as they all do here, by reading the source of every tool it was going to link to — ten of them, in our auto category.

The arithmetic was fine. The loan amortisation, the affordability solve, the depreciation curve and the power conversions all check out, and unlike our payroll tools none of them shipped embedded rates that could go stale.

The problem was that none of them knew which country you were in. Searching all ten for "certificate of entitlement", "road tax", "open market value" and "additional registration fee" returned nothing. No COE. No ARF. No PARF. No road tax for either country. The two costs that dominate car ownership in this region were absent. Road tax, a figure both governments publish to the cent, was buried in a generic "Other (tax, parking…)" field where a reader would have to guess.

Both road tax scales are now in our shared calculation kernel with the authority cited on every line, along with the COE and PARF rebate formulas and all three PARF schedules, guarded by 25 automated checks. A proper COE calculator is a bigger build and is queued rather than half-done.

One more thing, because it is the kind of error this guide is about. The first version of the fix added the road tax straight into the total without touching the currency — so a ringgit figure was being summed into a US-dollar total. That wasn't a labelling slip; it was wrong arithmetic. The bug survived until someone checked the output instead of just the code. Choosing a market now pins the currency.
