Why do car insurance rates increase?
Car insurance premiums have a nasty habit of rising each year — regardless of whether you've filed any claims. Why is that? Car insurance companies compensate for the money they pay out in claims per year through rate revisions. If an insurance company's claim payout total exceeded its premium revenue, it will often pass on those costs to customers the following year. On average, car insurance premiums increased by 2% between 2018 and 2019 — the most recent year for which data was available.
Let’s review the reasons behind car insurance rate increases.
Why did my car insurance go up without an accident or ticket?
You can expect your car insurance premium to increase if you've committed any traffic violations, added drivers to your policy, moved, changed or upgraded insurance coverage, or added a vehicle. If none of these events have occurred and you haven't filed an insurance claim, you could be wondering what sparked your higher premiums. In such a case, you could be the victim of a rate increase. In order to fully understand insurance rate increases, it’s important to know how insurance companies set your home or auto insurance premium. Most of the information used by car insurance companies is historical data used to predict what their future losses — or claim payments — could be.
Auto insurers don’t use only your information to create your profile. They also rely on related data, including your location, vehicle, age, credit score, and other factors to create a pricing profile. If you live in an area in which insurers experienced a higher loss-to-profit ratio than usual last year, you might experience a rate increase to account for the insurance company’s loss.

Looking at car insurance rates by region shows discrepancies based on geography. Some regions enjoyed rate decreases, while others endured significant premium increases. It all comes down to location.
- From 2011 to 2019, Oklahoma saw the greatest decline in auto insurance rates, with 2019 rates 7.9% lower than they were in 2011. However, from 2018 to 2019, premiums in Oklahoma increased by nearly 13%.
- Colorado saw the greatest rate hike from 2011 to 2019, with auto insurance premiums 86% higher in 2019 than they were in 2011. This trend was maintained in 2018 to 2019, increasing another 3.4%.
- Alaska saw the smallest change, with only a 1% net change between 2011 and 2019. The state did experience some year-to-year rate fluctuations during this period.

Looking at geography alone only paints a portion of the picture. Because car insurance is regulated at the state level and rated on a ZIP-by-ZIP basis, it's highly unique. As there are more 50,000 zip codes in the US, our analysis sticks to specific states for the sake of brevity.

Which car insurance companies have increased rates recently?
While it’s nearly impossible to track down specific rate changes for every insurance company, most major insurers factor rate increases into their premium calculations. Since rate increases aren't consistent across the industry, it's important to find the company that will increase your rates the least. The only real way to do this is to shop around for an insurance policy with the cheapest rates. Remember, the rate increase is dependent on the previous year’s return-on-investment — you'll need to consistently gather insurance quotes every six months to ensure the cost of your car insurance premium doesn't go up.
