How to get the cheapest car insurance

There are plenty of ways to bring down the cost of car insurance. Take these steps to get the best possible price on the coverage you need.

Step 1: Get the right type of coverage

You can keep the cost of car insurance low by buying only the minimum amount of liability coverage required by your state. However, this strategy can backfire. Liability coverage pays only for property damage and injuries to others if you cause an accident. It doesn't cover repairs to your vehicle, leaving you on the hook for those costs.

It can save you money in the long run to spend a little more each month to add collision insurance and comprehensive insurance to your coverage. Collision coverage insurance pays for repairs or replacement after an accident, and comprehensive insurance pays if your car is stolen or damaged by something other than an accident with another vehicle, such as a storm or vandalism.

Step 2: Opt for a higher deductible

Your car insurance deductible is the amount you pay to repair or replace your car before collision or comprehensive coverage kicks in. Opting for a higher deductible can lower your car insurance cost. For example, increasing your deductible for collision and comprehensive from $200 to $500 can reduce your rate by as much as 30%, according to III. Just make sure you have enough in an emergency fund to cover your deductible.

Step 3: Shop around for the lowest quotes

It pays to get quotes from multiple insurance companies because each insurer has its own methodology for setting car insurance premiums. As a result, quotes for comparable policies can be substantially different.

There are several ways to comparison shop for car insurance quotes:

• Online car insurance comparison toolsshow car insurance premiums from different insurers and let you compare prices for similar policies.

• Car insurance websitesallow you to expand your search to companies that aren't featured in online comparison tools.

• Independent insurance agentscan do the comparison shopping for you by getting quotes from several companies.

• Captive insurance agentsonly sell products from a single insurance company, such as Allstate, Nationwide, and State Farm.

Step 4: Take advantage of car insurance discounts

Ask your insurance agent or car insurance company whether you qualify for any of these discounts that can lower your premium:

• Multi-policy discount:Most insurers offer a discount if you buy more than one insurance policy, such as auto and home or auto and renters insurance.

• Low mileage discount:Many car insurance companies offer discounts if you drive less than the average number of miles per year. If you put relatively few miles on your car, explore pay-per-mile car insurance.

• Safe driver discount:You can get a lower rate if you haven't had any accidents or moving violations in a certain number of years.

• Anti-theft device discount:Several car insurance companies offer a security discount for having an anti-theft device or technology to protect your car.

• Good student discount:Many insurers offer good student discounts for high school and college students with a high GPA.

• Defensive driving discount:Young drivers and seniors may get lower rates by taking an approved safe driving course.

• Military discount:A variety of insurers offer special discounts for serving in the military.

• Loyalty discount:Some insurers offer discounts for staying with them for a certain number of years, which can be worthwhile if you can't save money by switching companies.

• Autopay discount:You might get a discount by setting up automatic premium payments. Opting for electronic statements rather than paper also might save you money.

• Payment in full discount:Save money by paying for six months or a year of coverage at once instead of monthly.

Step 5: Don't focus on monthly price alone

There's more to choosing the right auto insurance policy than cost alone. Trying to secure the most affordable car insurance policy might save money up front, but could lead to higher costs if coverage is inadequate.

Ask about any coverage restrictions before buying a policy. For example, will your coverage level drop if you drive outside of your state? Will your insurance cover a friend if they get into an accident when borrowing your car?

Also, check online reviews and complaints for insurers you're considering to find a company with a good customer service track record.

Step 6: Review your coverage annually

Review your car insurance coverage each year to ensure you're getting all discounts you qualify for and not paying more than necessary. For example, if your income has increased, you might be able to afford a higher deductible, which will lower your premium.

Also, use your annual check-in to get quotes from other insurers to see if you can get a lower rate elsewhere. However, make sure to account for the loss of any discounts with your current insurer before switching.

Methodology

Unless stated otherwise, the estimates above are generated by Savvy Insurance Solutions' in-house machine learning models based on over 3 million data points, and include more than 15 of the largest insurance companies in the Savvy nationwide data set. This includes data from more than 2 million insurance accounts connected through Trellis Connect, an in-house technology allowing consumers to "link" their insurance accounts before searching for insurance, and tens of thousands of policies bound by Trellis' own agents. It takes into account a myriad of factors to create predictions, such as:

• Policyholder age

• Number of vehicles

• ZIP code

• Vehicle age

• Insurer

• …and more

Savvy Insurance Solutions creates estimates by running models against multiple inputs to the parameters of interest. For instance, the "teen driver" estimates were created by adjusting the policyholder age input into the pricing model while keeping all other variables steady from the baseline for "full coverage." The models enable hyper-personalized estimates that take into account a plethora of user attribute permutations (e.g., teen drivers in specific states, teen drivers with new vehicles, teen drivers in specific states with new vehicles) to provide individuals with a unique and tailored experience. The charts above are a subset of the kinds of personalization Savvy Insurance Solutions can do.
