How Is the Price of Comprehensive (Casco) Insurance Calculated?
Comprehensive (Casco) insurance is one of the most flexible forms of vehicle protection. Unlike the mandatory Third Party Liability insurance, Casco is voluntary, but often extremely necessary—especially for newer or more expensive vehicles. If you are wondering how much Casco insurance will cost you and what exactly determines the price, this article will examine all the influencing factors, as well as how you can easily obtain an accurate online quote through Trusti.bg.
What Does Casco Insurance Cover?
Before looking at pricing, it is important to understand what Casco insurance covers. It is designed to protect the vehicle itself, regardless of who is at fault in an incident. Coverage can be structured differently depending on the owner’s needs and insurers’ offers, but most commonly includes:
- Damage from road traffic accidents: regardless of whether the fault is yours or another driver’s, Casco covers repair costs. This includes collisions, impacts, rollovers, and other road-related damage.
- Natural disasters: hail, storms, hurricanes, floods, falling branches or trees, snow accumulation, and other natural events that may damage your vehicle.
- Fire and explosion: covers damage caused by self-ignition of the vehicle or external factors such as nearby fires or explosions.
- Theft or robbery: if the vehicle is stolen or forcibly taken, the insurer pays compensation based on depreciation and the vehicle’s assessed value at the time of the event.
- Vandalism and malicious acts: covers intentional damage by third parties—scratches, broken mirrors, headlights, windows, and other exterior or interior damage.
- Additional equipment: the option to insure non-standard equipment such as alloy wheels, factory-installed or aftermarket audio systems, multimedia screens, navigation systems, alarms, and more.
- Roadside assistance and replacement vehicle: many insurers offer additional services such as free roadside assistance in case of breakdowns, technical issues, or accidents. A replacement vehicle during repairs is also included in some premium packages.
It is important to note that coverage can be:
- Full coverage: includes all the risks listed above and provides the most comprehensive protection.
- Limited coverage: the client selects specific risks, such as natural disasters and theft only, without coverage for accidents or vandalism. This results in a lower premium but also reduced protection.
Key Factors That Affect the Price of Casco Insurance
The price of Casco insurance is not fixed. It is determined individually for each vehicle based on multiple parameters. The price difference between two seemingly similar vehicles can be significant, depending on their characteristics, history, and usage.
- Brand, model, and market value of the vehicle
The higher the vehicle’s market value, the greater the amount the insurer must cover in the event of total loss or theft. This leads to a higher annual premium. Luxury or sports models (such as Mercedes, BMW, Tesla) fall into a higher insurance price category. - Year of manufacture and depreciation
Newer vehicles are considered more valuable both in terms of market price and lower risk of technical failure. Accordingly, Casco insurance for a new car is more expensive, especially during the first three years. For older vehicles, insurers apply a depreciation rate that reduces the insured value. - User location and parking conditions
Urban environments carry higher risks of accidents, theft, and vandalism. For example, drivers in Sofia and Plovdiv may receive higher quotes than those in smaller towns. Where the vehicle is parked also matters—garage, yard, underground parking, or street. Parking in a secured garage reduces risk and therefore the premium. - Claims and damage history
If you have filed Casco claims in the past, this may affect the price of your new policy. Conversely, if you have had no incidents in recent years, most insurers offer bonuses and discounts (bonus-malus system). - Chosen coverage and deductible
Full Casco coverage includes all major risks and costs more than partial coverage, which usually includes only natural disasters and theft.
The deductible is the portion of costs the insured pays when a claim occurs. The higher the deductible (e.g., BGN 300 instead of BGN 150), the lower the premium. This is an effective way to reduce the price if you are willing to assume a small risk. - Vehicle usage
Vehicles used mainly for personal purposes are considered lower risk than commercial ones. Taxis, rental cars, courier vehicles, or company cars are classified as higher risk and have significantly higher premiums. Declaring the actual use is essential, as incorrect information may lead to claim denial. - Choice of repair service
Some insurers require repairs to be carried out only at their approved or licensed repair shops. This allows them to control quality and costs, and the insurance is often cheaper under such conditions. If you prefer free choice of repair shop, the price may increase. - Additional services and policy extras
Adding services such as:- Roadside assistance in Bulgaria and abroad
- Replacement vehicle during repairs
- Extended coverage abroad
- SMS or email notifications for policy changes
In short, the price of Casco insurance is influenced by a combination of objective factors (such as vehicle age and location) as well as your personal choices—coverage, services, deductible, and usage. Through the Trusti.bg platform, you can quickly and easily compare offers from different insurers and choose the best price for your needs.
