A lower car insurance premium can look like an easy win until you notice that the deductible doubled, an important coverage limit changed, or a discount disappeared. Other factors aren't obvious from the bill at all. Claims history, credit-based insurance information, telematics data, vehicle characteristics, and lender requirements can affect coverage or pricing.
Instead of treating these factors as insurance-company “secrets,” it makes sense to check the information insurers and lenders actually use. Some details can be corrected or changed. Others can help explain why one quote costs less than another.
1. Compare the Whole Policy, Not Only the Premium
Start with the number most people notice first: the premium.
A lower quote doesn't necessarily mean you're getting equivalent insurance for less. The new policy might have different liability limits, higher collision or comprehensive deductibles, or different optional coverage.
When comparing quotes, line up the same drivers, vehicles, coverage types, limits, and deductibles. The National Association of Insurance Commissioners (NAIC) advises consumers to compare coverage and other policy details rather than assuming the lowest quote is automatically the best choice.
This makes the real question less about which company has the lowest advertised price and more about what you're receiving for that price.
2. Check Your Deductibles Before Choosing the Cheaper Quote
Collision and comprehensive insurance often come with deductibles. These are amounts you're responsible for paying toward covered damage before the applicable insurance payment is calculated.
A higher deductible can reduce the premium for that coverage, but it increases your potential out-of-pocket expense after a loss.
For example, suppose two policies provide otherwise comparable collision coverage. One has a $500 deductible and the other has a $1,000 deductible. The second policy may have a lower premium, but you're accepting an additional $500 of potential expense if you make a covered collision claim.
Before increasing a deductible, compare the annual premium savings with the additional amount you'd have to pay after a loss. The lower premium matters only if you're comfortable handling the higher deductible.
3. Review Your Claims History for Incorrect Information
Past claims can affect auto insurance underwriting and pricing. Insurers may obtain claims-history information when evaluating an application or renewal.
That makes accuracy important.
If a consumer reporting agency maintains insurance claims information about you, federal law gives you rights concerning your consumer report, including the ability to dispute inaccurate information.
If quotes seem unexpectedly high, reviewing relevant consumer reports can help identify incorrect claims or other information that may need to be disputed.
Don't assume changing insurance companies automatically erases past claims from consideration. A new insurer may obtain historical information when evaluating your application.
4. Ask Which Discounts Are Already Applied
Auto insurers commonly have discounts tied to factors such as multiple policies, multiple vehicles, driving history, mileage, driver education, safety equipment, or student eligibility. The exact discounts depend on the company and state.
Some discounts may be applied based on information the insurer already has. Others may require enrollment, documentation, or updated information.
Ask your insurer for the discounts available in your state and compare that list with the ones appearing on your policy.
Changes in your household can matter too. A student's eligibility, annual mileage, another vehicle, or an additional insurance policy with the same company could affect which discounts are available.
Staying with one company for years doesn't guarantee that you're receiving the lowest available premium. At renewal, compare substantially equivalent quotes from several insurers rather than assuming loyalty automatically produces the best price.
5. Read the Rules Before Joining a Telematics Program
Usage-based insurance programs can use a smartphone app, plug-in device, or technology installed in the vehicle to collect driving information.
Depending on the program, telematics can track information such as mileage, time of day, rapid acceleration, hard braking, hard cornering, and location. Insurers may then use permitted data when determining premiums.
Drivers shouldn't assume participation guarantees permanent savings.
Before enrolling, check:
- What information the program collects
- How that information affects the premium
- If driving behavior can increase the price
- How long you need to participate
- What happens if you leave the program
- What privacy terms apply to the collected data
Program terms and state rules differ, so read the insurer's current terms before agreeing to monitoring.
6. Check the Insurance Cost Before Adding a Teen Driver
Adding a newly licensed driver can substantially change a household's insurance premium.
Insurers can use factors such as age, driving experience, driving history, vehicle use, and other permitted rating information when calculating premiums. The rules differ by state and insurer.
Before adding a young driver, ask your current insurer for the new premium and compare substantially equivalent quotes elsewhere.
Also check available discounts. Some insurers provide good-student, driver-training, or other discounts for qualifying young drivers.
The vehicle assigned to the driver may matter as well. Comparing the cost of different household vehicle arrangements can show how each option affects the premium.
7. Know What Insurance Your Auto Lender Requires
Financing a vehicle can change the coverage you need to carry.
State law may require liability insurance, while lenders generally have a separate financial interest in protecting the vehicle securing the loan. Lenders commonly require physical-damage protection, which generally means maintaining collision and comprehensive coverage on a financed vehicle.
Check the loan agreement for required coverage and any deductible requirements before buying the vehicle.
Allowing required insurance to lapse can create an expensive problem. Depending on the loan contract, the lender may obtain force-placed insurance and charge the borrower for it. The Consumer Financial Protection Bureau warns that this coverage protects the lender's interest and can cost considerably more than insurance consumers obtain themselves.
The monthly loan payment therefore isn't the only recurring cost worth checking before financing a car.
8. Get an Insurance Quote Before Buying Your Next Vehicle
The vehicle itself can affect insurance pricing.
Insurers can account for vehicle type and the expected cost of claims. Repair and replacement costs, theft experience, vehicle characteristics, safety-related factors, and other permitted information can affect premiums.
This is much easier to address before buying the car.
If you've narrowed your search to two or three vehicles, request insurance quotes for each using the same drivers and coverage selections. A vehicle with a similar purchase price can still have a different insurance cost.
That gives you another ownership expense to compare before signing the purchase agreement.
9. Understand Credit-Based Insurance Scores
In states where their use is permitted, insurers may use credit information when underwriting or pricing auto insurance.
A credit-based insurance score is different from the ordinary credit score associated with borrowing money. Insurance scores use information from a person's credit history to help estimate the likelihood of future insurance losses.
State laws place restrictions on how these scores can be used, and some states prohibit certain uses. In many states, an insurer can't use a credit-based insurance score as the sole reason for certain adverse actions.
Because these scores rely on credit-report information, checking your credit reports for inaccuracies can be useful. If you find an error, follow the credit bureau's dispute process rather than assuming the insurer can correct the underlying credit record.
10. Know Which Pricing Factors Are Harder to Change
Some factors explain your premium without giving you an immediate way to reduce it.
Location is one example. Auto insurers can use garage location and geographic information when determining rates, subject to state rules. Vehicle use, driving history, annual mileage, age, driving experience, and other permitted characteristics may also influence pricing.
These factors help explain why two people with similar vehicles can receive different quotes.
That doesn't mean a driver should move or make another major life decision solely to lower an insurance bill. Instead, knowing which inputs you can't readily change helps you focus on the ones you can.
Five Things to Check Before Your Next Renewal
You don't need to reverse-engineer an insurer's entire pricing formula every time your policy renews.
Start with five checks:
- Compare equivalent quotes. Keep coverage types, limits, drivers, vehicles, and deductibles consistent.
- Read your declarations page. Check coverage limits, deductibles, listed drivers, vehicles, and other policy information.
- Review your discounts. Ask which discounts are currently applied and if your circumstances qualify you for others.
- Check information that may affect pricing. Review relevant claims and credit information for errors when appropriate.
- Read optional-program terms. If you're using telematics or another usage-based program, know what data is collected and how it can affect your premium.
A low premium by itself doesn't tell you if a policy is a good deal. The useful comparison is the price of substantially equivalent protection.
Checking those details before renewal can show where genuine savings are available without cutting coverage simply to make the monthly bill look smaller.
