How motor premiums are calculated: age, car, claims history and usage
Motor insurance is compulsory in Singapore, but the premium two drivers pay for the same car can differ sharply. Here is what insurers weigh, and how to influence it.
Car insurance is required by law for anyone driving in Singapore, so the real question most drivers face is not whether to buy it but why the quote in front of them looks the way it does. Two drivers with the same car model can see meaningfully different premiums, and the gap usually comes down to a handful of factors insurers weigh every time they price a policy.
The driver
Age and driving experience are among the first things an insurer looks at, because claims data across the industry consistently shows that newer and younger drivers are statistically more likely to be involved in an accident. A driver who has held a licence for a short time, regardless of their actual age, will typically see a higher premium than someone with the same age but a longer clean driving record. This is also why some insurers ask about the number of years since you first obtained your licence, not just your date of birth.
The car
The vehicle itself affects the quote in several ways:
- Make, model and engine capacity. More powerful or higher-value cars generally cost more to insure, both because repair and replacement costs are higher and because some models carry different claims histories across the market.
- Age of the vehicle. Older cars can be cheaper to insure for third-party liability, but may see a lower payout on a total-loss claim if the insurer values the car below what you expect, since payouts are usually based on market value rather than what you originally paid.
- Usage of the car. Whether the car is used for private commuting, for business, or for ride-hailing changes the risk profile substantially, and using a private car for commercial purposes without declaring it can affect a claim later, not just the premium quoted upfront.
Your claims history and the No-Claim Discount
Most insurers in Singapore offer a No-Claim Discount that reduces your premium the longer you go without making a claim, and the discount is usually structured to grow year on year for continued claim-free driving. Making a claim, even a small one, typically resets or reduces this discount, which is one reason some drivers choose to pay for minor repairs themselves rather than claim, if the repair cost is close to what the lost discount would cost them over the following renewals.
Because the discount schedule and the exact percentages vary by insurer and can change over time, it is worth checking the current No-Claim Discount table with your own insurer rather than assuming a figure from a previous policy or a different insurer still applies.
Excess and deductibles
The excess is the amount you agree to pay out of pocket before the insurer covers the rest of a claim. Choosing a higher excess generally lowers your premium, because you are absorbing more of the small-claim risk yourself, while a lower excess raises the premium but reduces what you pay when something does go wrong. This is a genuine trade-off rather than a one-size-fits-all choice, and it is worth setting deliberately rather than accepting whatever an insurer defaults to.
Where the policy type matters
Comprehensive, third-party fire and theft, and third-party-only cover are priced very differently, since they cover different scopes of loss. Comprehensive cover, which typically includes damage to your own car as well as liability to others, costs more than third-party-only cover, which is the legal minimum but leaves your own vehicle's damage uninsured. For a newer or higher-value car, the gap in what you would pay out of pocket without comprehensive cover is usually large enough to make the additional premium worth comparing carefully rather than dismissing outright.
What you can actually control
Of the factors above, drivers have direct influence over their choice of excess, the level of cover they buy, whether they claim for minor incidents, and how honestly they declare the car's usage. Age and driving history are fixed at the point of quoting, but a clean record compounds in your favour over time through the No-Claim Discount, which is the single biggest lever most drivers have for reducing their premium year after year.
Talk to an advisor
Motor premiums are one of the more mechanical corners of insurance to price, but the right balance of excess, cover type and add-ons still depends on how you actually use the car. An advisor can compare quotes at /compare/singapore/motor and check whether your current policy still matches how you drive. Find one through our advisor directory, or ask our assistant to explain a quote you have received.
