How to calculate how much car insurance coverage you need
If you're looking for a new car insurance policy, it's important to understand the various coverage components that go into a policy.
The typical auto insurance policy may consist of six coverage types:
- Comprehensive coverage
- Collision coverage
- Uninsured and underinsured motorist coverage
- Auto liability coverage
- Medical payments coverage
- Personal injury protection
Comprehensive and collision coverages are not mandatory. Most insurance companies offer the ability to build a policy that suits your financial situation and driving needs.
How car insurance premiums are calculated
An insurance company looks at a driver's complete profile to set the policy's rates. A driver's profile includes several factors, some of which are in their control: maintaining a good driving record or driving an affordable car to insure.
Driving profiles and insurance rates
The amount a driver pays for insurance is based on several factors. These considerations, including location, age, gender, marital status, credit score, vehicle, and auto insurance and driving history, constitute the bedrock of a car insurance rate. The less risk posed by a client to an insurance company, the lower their premium will be.

Demographics and auto insurance rates
Insurance companies also take into consideration applicants' age, gender, credit score, marital status and homeownership status. Insurers use this information in an attempt to understand the risk posed by a client in order to assign an insurance rate.
Location and car insurance rates
Auto insurance is regulated by each U.S. state and priced based on the ZIP code in which a driver resides. If a state requires its drivers' basic minimum coverage to be high, its residents may face higher insurance costs.
This is one reason car insurance in Michigan is so expensive. Because Michigan is a no-fault state with high PIP insurance requirements, residents are forced to pay more for auto insurance than are drivers in other states. At the ZIP code level, higher rates of claims could lead to pricier premiums, as an insurance company adjusts for the increased likelihood of accidents and the greater probability of claims payouts.
Insurance history and insurance pricing
Insurance companies prefer to insure drivers with reliable insurance histories. A lacking or incomplete insurance record can be a red flag to an insurance company. Insurance companies see drivers with a long history of high insurance limits as financially responsible, and therefore a lower risk than a driver without a positive insurance history.
Comprehensive and collision coverage overview
Both of these coverages protect your vehicle from physical damage. Your collision coverage protects your vehicle if you collide with another car or fixed object whereas your comprehensive coverage protects your vehicle from weather-related incidents, animals, or vandalism.
These coverages are not required by state law but can be required if you’re leasing or financing a vehicle. Both are also subject to a deductible — what you pay prior to your insurance company reimbursing you for any damage.

Underinsured/uninsured motorist coverage
Uninsured and underinsured coverage pays for damages in the event the at-fault driver in a collision doesn't have insurance — or doesn't have enough insurance — to cover the damages inflicted. Underinsured and uninsured coverage usually falls into one of two buckets:
- Uninsured property damage insurance coverage: Coverage for a vehicle in the event of monetary damages.
- Uninsured bodily injury insurance coverage: Coverage for peoples' medical bills and other fees if bodily injury is sustained.
