Your car insurance NCD, the No-Claim Discount, is the biggest lever you have over the price of motor cover in Singapore, and the easiest to lose. Drive five years without a claim and most insurers knock 50% off your premium, turning an S$1,800 policy into roughly S$900. The catch sits in the small print: one at-fault claim can drag a 50% discount down to 20% overnight, and a second claim in the same year zeros it entirely. That is why insurers sell an add-on called NCD protection, and why deciding whether to buy it is worth more than the cost of the cover itself. This guide lays out the exact NCD tiers, the step-down scale after a claim, what protection actually costs in 2026, and the cases where paying for it is throwing money away.
NCD stands for No-Claim Discount. It is a reward for not claiming on your policy, applied as a percentage off your base premium at each renewal. The General Insurance Association of Singapore (GIA) sets a standard scale that almost every local insurer follows, so the tiers below hold whether you are with Income, AIG, Sompo, or a direct insurer.
Each claim-free year you complete adds another 10% for a private car, capped at 50% after five clean years. Motorcycles and commercial vehicles run a slower, lower scale that tops out at 20%. The discount is not automatic goodwill from your insurer; it is earned year by year and recorded against you, not the car, which is why it travels with you when you switch insurers or buy a new vehicle.
A few insurers stretch the ceiling. DirectAsia, for example, offers an NCD60 tier for drivers with 10 or more claim-free years (as of June 2026), 10 percentage points beyond the GIA standard. Treat anything above 50% as a marketing perk that only applies while you stay with that insurer.
| Claim-free years | Private car | Motorcycle / commercial |
|---|---|---|
| 1 year | 10% | 10% |
| 2 years | 20% | 15% |
| 3 years | 30% | 20% |
| 4 years | 40% | 20% (capped) |
| 5+ years | 50% | 20% (capped) |
| 10+ years | Up to 60% (select insurers only) | 20% (capped) |
The dollar value scales with your base premium, so the higher your raw price, the more the discount saves you. A driver paying an S$1,800 base premium at NCD50 pays roughly S$900. Move down to NCD20 after a claim and that same policy jumps to about S$1,440, a S$540 swing for one incident, before the separate loading insurers add for having claimed at all.
That second penalty matters and gets glossed over. Losing NCD is one cost; the claim itself also marks your record, and many insurers raise the base premium for a claimed-on policy regardless of the discount. So the real cost of an at-fault claim is the lost discount plus a fatter starting price. If you are weighing whether to claim for minor damage, run the math on both before you call your insurer.
Premiums themselves are volatile, so use the car cost calculator to estimate where insurance sits inside your total cost of ownership rather than treating the NCD percentage in isolation. A 50% discount on a cheap policy is worth less than a 30% discount on an expensive one.
| NCD tier | Discount | Approx. premium |
|---|---|---|
| NCD0 | 0% | S$1,800 |
| NCD20 | 20% | S$1,440 |
| NCD30 | 30% | S$1,260 |
| NCD40 | 40% | S$1,080 |
| NCD50 | 50% | S$900 |
This is where the discount earns its danger. After an at-fault claim, your NCD does not just drop one tier; it falls along a fixed step-back scale, and the higher you were, the further you fall. The GIA scale that most insurers apply is below.
Note that the drop is not symmetric. A driver at NCD50 keeps more cushion than the scale suggests because they fall to 20% rather than to zero, while anyone at NCD30 or below loses the lot. A second claim in the same policy year takes everyone to 0% regardless of where they started.
| NCD before claim | After 1 claim | After 2+ claims |
|---|---|---|
| 50% | 20% | 0% |
| 40% | 10% | 0% |
| 30% or below | 0% | 0% |
Not every claim costs you the discount. If you are found not at fault, or liable for less than 20% in an accident involving another identified vehicle, your NCD is protected automatically and stays put. The condition is that the other party is traceable, so a hit-and-run or a solo incident where you cannot recover from anyone usually still counts against you.
Report any accident to your insurer within 24 hours even when you are sure you were not at fault. Miss that window and you can be penalised on the claim and lose the not-at-fault protection, which is a needless way to forfeit a discount you were entitled to keep.
NCD protection is an optional add-on that lets you make one claim without your discount stepping back. It is usually sold only to drivers at NCD30 and above, and it is single-use: claim once and the protection is spent until you rebuild. A handful of insurers, such as Sompo, have bundled basic NCD protection free into certain plans (as of June 2026), but as a paid add-on it typically runs around 10% to 15% of your motor premium. On a S$900 NCD50 policy that is roughly S$90 to S$135 a year.
The decision is a straight expected-value question. You are paying every year to guard against a loss that only bites if you make exactly one at-fault claim while sitting at a high tier. For an NCD50 driver, one claim costs about S$540 in lost discount, so a few clean years of paying S$90 to S$135 can still come out ahead if it saves that S$540 hit once. For an NCD30 driver, the potential loss is smaller and the protection often is not worth it.
Read the policy wording before assuming you are covered, because the premium add-on and the actual protection terms vary. Protected NCD is frequently non-transferable: if you switch insurers, the new insurer recognises your underlying NCD level but not the protection, and may not honour the protected entitlement at all. That undercuts the value if you are the type who shops around at every renewal.
NCD belongs to the policyholder, who must be the registered owner of the vehicle, not to the car. That means it follows you across insurers and across vehicles, but only within the same vehicle class. You cannot carry private-car NCD onto a motorcycle, and you cannot apply one NCD to two cars at the same time. Each vehicle you own builds and keeps its own record.
If you stop driving for a while, your NCD does not evaporate immediately. Most insurers hold it for 12 to 24 months after your last policy ends, so a gap between selling one car and buying the next is usually survivable. Confirm the exact window with your insurer, because it varies and the clock is unforgiving once it runs out.
Two traps catch people. First, being a named driver on someone else's policy earns you nothing; NCD only accrues to the policyholder, so years on a parent's or partner's policy do not build your own discount. Second, when you switch insurers you need an NCD confirmation letter from your previous insurer as proof; without it the new insurer may start you at zero. If you are timing a switch, our guide to renewing car insurance in Singapore covers how to carry the discount across cleanly.
Treat NCD as an asset you have spent years building. A driver at NCD50 is sitting on a discount worth hundreds of dollars a year, which is exactly why a single careless claim is so expensive and why the not-at-fault rule is worth knowing cold. Before claiming for minor damage, compare the repair cost against the lost discount plus the higher base premium; small bumps are often cheaper to pay out of pocket.
If you are deciding on protection, anchor on your tier. At NCD50 the maths usually favours buying it, especially if it comes free on a competitive plan. Below NCD30 it rarely pays. And whatever you decide, keep your NCD confirmation letter handy at renewal so you never restart the clock by accident. For the bigger picture on whether full cover is even right for your car, weigh it against your total running costs rather than the headline discount alone.
NCD rises 10% for every claim-free year on a private car, capped at 50% after five years. Motorcycles and commercial vehicles cap at 20%. A few insurers offer an NCD60 tier for 10-plus claim-free years, but that perk only applies while you stay with them.
Not entirely, but it drops sharply. An at-fault claim takes NCD50 down to 20%, NCD40 to 10%, and NCD30 or below to 0%. A second claim in the same policy year zeroes your discount regardless of your starting tier, unless you carry NCD protection.
It is most worth it at NCD50, where one claim costs roughly S$540 in lost discount on an S$1,800 base premium, against protection of about S$90 to S$135 a year. At lower tiers, or if you switch insurers often since protection rarely transfers, it usually is not worth the cost.
Yes, NCD follows the policyholder across insurers and across vehicles within the same class, as long as you are the registered owner. You need an NCD confirmation letter from your previous insurer as proof. You cannot move private-car NCD onto a motorcycle or apply one NCD to two cars at once.
Most insurers retain your NCD for 12 to 24 months after your last policy ends, so a gap between selling one car and buying the next is usually fine. Confirm the exact window with your insurer, because it varies and your discount resets to zero once it lapses.
