How Car Insurance Premiums are Calculated in Washington

Car insurance providers determine their rates based on a range of factors, and some have more impact on the cost than others. In Washington, the most important factors in terms of price are adding a teen driver to your policy, your age and the level of coverage you select.

If you add a teen driver to your car insurance, for instance, your rates will increase by 3.0x.

How Much Adding a Teen Driver Matters in Calculating Car Insurance in Washington

Insurers charge teen drivers higher premiums due to their inexperience. Teen drivers are more likely to get involved in accidents than other experienced drivers. Research shows drivers in this age category are nearly three times as likely as drivers aged 20 or older to be in a fatal crash.

In Washington, adding a teen driver to your policy can increase your car insurance rates by as much as 3x.

How Much Age of Driver Matters in Calculating Car Insurance in Washington

Your age also determines how much you pay for car insurance. Young drivers pay higher premiums since they tend to be more reckless than older drivers and are involved in accidents. Senior drivers also pay more than middle-aged drivers due to worsening health conditions, reduced vision, impaired hearing and slower motor reflexes.

If you are a 19 or 20-year-old driver, you’ll pay up to 2.3x more than a 40-year-old driver for car insurance in Washington.

How Much Coverage Level Matters in Calculating Car Insurance in Washington

Car insurance rates vary across coverage levels. That means your rate may be higher or lower than the state average based on the amount of coverage you purchase. To obtain an accurate quote from insurance companies, you will need to specify the average number of miles driven per year, type of coverage and deductible amount.

The cheapest car insurance in Washington is the state minimum liability-only. The most expensive is full coverage insurance with a limit of 100/300/100 and a $500 deductible, about 2.2x more than the state minimum.

How Much The Model Matters in Calculating Car Insurance in Washington

The model of your car also determines how much you will pay for car insurance in Washington. High-value cars are often riskier to insure, meaning that you will need to pay more to get insurance. Luxury cars and sports cars with expensive repair bills have higher premiums than SUVs and other cheaper models that may not be prone to damage or theft.

In Washington, car insurance policies are up to 2x more expensive depending on the car model.

How Much Credit Score Matters in Calculating Car Insurance in Washington

Your credit score is another variable that insurers consider when determining the cost of your car insurance in Washington. If you have an excellent credit score, your premiums will be lower. However, if you have a poor credit score, you will pay higher insurance premiums.

Drivers who have poor credit can pay up to 1.9x more than those with good credit.

How to Calculate How Much Car Insurance You Need in Washington

One of the most significant factors influencing your car insurance rates is the level of coverage you choose. To find a policy that balances cost and protection, you need to determine how much coverage you need and can afford.

So, how do you calculate how much car insurance you need in Washington? By law, all drivers in the state must have bodily injury liability and property damage liability coverage. You may opt to purchase comprehensive and collision insurance depending on your needs and budget.


Understand Washington car insurance requirements

You can figure out how much car insurance you need by looking up the Washington minimum car insurance requirements.

In a nutshell, state law requires car insurance with a minimum of 25/50/10 coverage. That means $25,000 in bodily injury per person, $50,000 in bodily injury per accident and $10,000 in property damage. While you’re not required to buy comprehensive and collision insurance, it does protect you against damages to your car.


Consider Purchasing Additional Liability Insurance

You may need liability insurance above the state minimum if you want financial protection in the event you’re in a major accident.

In Washington, a policy that protects you for $300,000 in bodily injury per accident costs an average of $904 per year. The state minimum policy, on the other hand, costs about $605 annually.


Decide whether or not to buy comprehensive and collision insurance

Comprehensive and collision insurance is optional in Washington, although it’s recommended due to the high level of protection it provides if you’re in a serious accident. In fact, some lenders need drivers to have full coverage before providing a lease or financing agreement.

In Washington, it will cost you an average of $347 per year to add comprehensive and collision coverage with a deductible of $1,000 to your policy. If the replacement value of your car is not very high, you may consider forfeiting this add-on to save on costs.


Consider buying additional protection besides these core coverages

Washington drivers are not required by law to purchase uninsured/underinsured motorist coverage. However, with about 21.7% of drivers in Washington uninsured or underinsured, you may wish to consider buying this additional auto insurance coverage. It’ll protect you if you’re ever in a car accident caused by an uninsured driver.

Personal injury protection is also optional in Washington. You can purchase either PIP or medical payments insurance. The latter is known as MedPay, and like PIP, it’s an add-on that covers your medical expenses in an accident regardless of fault.
