Your car insurance renewal notice arrives with a higher premium. You have had no accidents or tickets. Many drivers simply pay it. But insurers price policies differently, and the company that was cheapest three years ago may not be cheapest now.
Key Takeaways
- Compare quotes at renewal, after major life changes, or every year or two.
- Compare policies with identical coverage limits and deductibles; otherwise the comparison is misleading.
- A higher deductible lowers premiums, but only makes sense if you can afford the deductible from savings.
- Ask about discounts for bundling, safe driving, low mileage, paying in full, paperless billing and vehicle safety features.
Why premiums change
Premiums are affected by your driving record and claims history, where you live and park, your vehicle and its repair costs, annual mileage, credit-based insurance scores in most states, and insurer-wide rate changes driven by repair costs and claims trends. Insurers weigh these factors differently, which is why quotes for the same driver can vary widely.
When to shop
- At renewal, especially if your premium rises
- After moving
- After buying or selling a car
- After marriage, divorce or adding a teen driver
- When an accident or ticket drops off your record
- After a significant improvement in credit, in states where credit is used
How to compare fairly
Start with your current declarations page. It lists:
- Liability limits, often shown as three numbers such as 100/300/100 — bodily injury per person, bodily injury per accident, and property damage, in thousands of dollars
- Collision and comprehensive deductibles
- Uninsured and underinsured motorist coverage
- Medical payments or personal injury protection
- Optional coverages, such as rental reimbursement and roadside assistance
Request quotes with the same coverages. A cheaper quote with lower limits is not a fair comparison — it is less insurance.
Liability limits matter
State minimum liability limits are often low. A serious accident can exceed them, leaving you personally responsible for the rest. Many consumer advocates suggest carrying higher limits than the minimum, especially if you have savings or a home to protect. Raising limits often costs less than people expect, so price it before deciding.
Deductible math
Collision and comprehensive deductibles are what you pay before insurance covers a claim. Higher deductibles lower premiums.
Example:
- $500 deductible: premium $1,400 a year
- $1,000 deductible: premium $1,250 a year
Raising the deductible saves $150 a year but adds $500 of risk per claim. If you file a claim less than once every three or four years, the higher deductible usually comes out ahead — but only if you could comfortably pay $1,000 tomorrow.
Should you drop collision coverage?
On an older car, collision and comprehensive may cost more than they are worth. A common rule of thumb: if the yearly cost of these coverages is more than about 10% of the car’s value, consider dropping them, provided you could repair or replace the car yourself. Keep them if the car has a loan or lease, since lenders require them.
Commonly missed discounts
- Bundling home or renters insurance with auto
- Multi-vehicle
- Safe driver or claims-free
- Low mileage, especially for remote workers
- Telematics programs that track driving behaviour
- Good student for young drivers
- Defensive driving courses, in some states
- Paying in full or setting up automatic payments
- Paperless billing
- Vehicle safety and anti-theft features
- Affiliation discounts through employers, alumni groups or professional organisations
Ask each insurer to list the discounts applied to your quote, then ask what else you might qualify for.
Switching insurers
- Buy the new policy first, with coverage starting before the old policy ends, so you never have a gap.
- Cancel the old policy in writing and request a refund of any unused premium.
- Update proof of insurance in your vehicle and with any lender.
Frequently Asked Questions
Will shopping for quotes affect my credit? Insurance quotes typically use soft inquiries that do not affect your credit score.
Is the cheapest insurer always best? Consider claims service and financial strength, not just price.
Do telematics programs always save money? They can reward safe driving, but some programs may raise rates if they record risky habits.
How often should I shop? At least every year or two, and after major life changes.
The bottom line
Car insurance pricing changes over time. Compare identical coverage at renewal, choose a deductible you can afford, keep sensible liability limits, and ask for every discount you qualify for.
