Many motorists assume that as their vehicle gets older and loses value, their car insurance premium should automatically decrease. This assumption seems logical: if the car is worth less, the financial risk to the insurer should also be lower.
In reality, the way insurers calculate premiums is far more complex. While a vehicle’s market value usually declines each year, several other factors influence what you pay for car insurance. These include the cost of repairs, inflation, theft risk, claims history, and the overall cost of insurance across the industry.
Understanding how these elements work together can help drivers make better decisions about their insurance cover and avoid surprises when reviewing or renewing their policy.
Although vehicles depreciate over time, the cost of repairing them often increases. Modern vehicles include sophisticated electronics such as sensors, cameras, advanced driver-assistance systems and specialised materials. These technologies improve safety but can significantly increase repair costs.
According to Statistics South Africa Consumer Price Index reports, inflation continues to influence the cost of goods and services across the economy, including vehicle parts and labour. As repair costs increase, insurers must account for these expenses when calculating premiums.
This means that even though your vehicle may be worth less than when you purchased it, the cost of repairing damage after an accident may still be high.
Insurance premiums are calculated using a range of variables. Understanding these factors explains why premiums may remain stable even when your vehicle depreciates.
Modern vehicles are more technologically advanced than ever before. While these systems improve safety, they also increase the cost of repairs. Even a minor accident can involve replacing sensors, recalibrating driver-assistance systems, or sourcing specialised components.
If you want to understand the types of cover that protect against these risks, MiWay explains the details in their guide to comprehensive car insurance.
Comprehensive cover typically protects against accidents, theft, and damage to your vehicle, which is why repair costs play a significant role in determining insurance pricing.
Inflation affects nearly every sector of the economy, including the automotive repair industry. Spare parts, specialised tools, and labour costs can increase over time, particularly when parts need to be imported.
When these costs rise faster than vehicle depreciation, insurers may need to maintain or adjust premiums to reflect the true cost of potential claims.
Your car insurance premium is not based only on the vehicle. Insurers also evaluate the driver's risk profile. This may include driving history, previous claims, annual mileage, and where the vehicle is typically parked.
If you want to better understand what happens after an incident, MiWay provides a helpful explanation in their guide to navigating an insurance claim.
Drivers with fewer claims and a lower risk profile may benefit from more favourable premiums.
Insurance premiums are also influenced by broader industry trends such as theft, fraud, and accident rates.
According to the South African Insurance Crime Bureau, vehicle-related claims remain a significant contributor to insurance costs across the country. When theft or accident rates increase, insurers may adjust pricing across the market.
In some cases, older vehicles may actually become more expensive to insure. This can happen when replacement parts become harder to find or when certain models are targeted more frequently by thieves.
Older vehicles may also lack modern safety systems that help prevent accidents, which can increase risk for insurers.
Because many variables affect insurance pricing, reviewing your policy regularly is a smart way to ensure your cover still matches your needs.
A policy review can help you adjust your insured value, update personal details, or review your excess to ensure your premium reflects your current situation.
