How often should you shop for car insurance?
Compare car insurance prices at least once a year, a few weeks before renewal, and after any change that affects your rate. Here is when and why.
Compare car insurance prices at least once a year, ideally three to six weeks before your policy renews, and again whenever something changes that affects your rate: a move, a new car, a new driver, a marriage, or an accident or ticket dropping off your record. Shopping more often than that rarely pays, but going years without checking is how many drivers end up overpaying.
Why prices drift apart over time
Your premium is set by your insurer's current rate plan applied to your rating factors. Both move:
- Insurers change their rates on different schedules. Each company files rate changes with state regulators when its own claims costs and profit targets require it. One insurer may take a large increase this year while a competitor holds steady, then the positions reverse.
- Insurers weigh the same facts differently. One company may price a recent speeding ticket heavily and another lightly; one may favor your ZIP code, your car model or your age group more than others do.
- Your profile changes. Turning 25, marrying, adding a teen, buying a newer car or moving across town can each change which company is cheapest for you.
Because of this, the insurer that was the best price when you bought your policy may not be the best price three years later, even if your own record is spotless.
The once-a-year check
Make one structured comparison each year, timed to your policy renewal.
- Watch for the renewal notice. Insurers send it ahead of the renewal date; the timing of that notice is set by state rules and varies. Many policies renew every six months, so pick one of the two renewals each year for a full comparison.
- Measure the change. Enter last term's and this term's premium into the renewal rate increase checker to see the increase in dollars and percent. If your premium rose and your coverage, cars and drivers did not change, that is a strong reason to compare (see why your premium went up at renewal with no claims).
- Get three or more quotes at identical coverage, using your declarations page as the template, and compare annual totals in the car insurance quote comparison worksheet.
- Ask your current insurer to review your policy. Missing discounts, an outdated mileage estimate or a driver who has moved out can be fixed without switching.
- Decide. Switch if the saving is meaningful after counting what you would give up; otherwise renew knowing your price is competitive.
Shopping early can itself save money
Some insurers reward buying ahead of your current policy's expiration. GEICO lists an "Early Shopper" discount in some states for buying a new policy before your existing one expires, saying "the more in advance you buy, the higher discount you could get". American Family offers an early-bird discount if you request a quote "at least one week and up to 60 days" before the new policy takes effect. Availability varies by state.
Life events that justify shopping right away
| Event | Why it can change the cheapest insurer |
|---|---|
| Moving, even within your city | Territory rating changes with your garaging ZIP code |
| Buying or replacing a car | Repair costs, theft rates and safety features vary by model |
| Adding a teen driver | Insurers price young drivers very differently |
| Marriage or divorce | Marital status is a rating factor in many states, and households combine or split policies |
| A ticket or accident ages off | Surcharges usually last a set number of years (see how long accidents and tickets affect your rates) |
| Turning 25 | Many insurers' age-based rates drop in the mid-20s |
| Credit improvement | In most states, a better credit-based insurance score can lower rates at some insurers |
| Big change in mileage | A new job, remote work or retirement can qualify you for low-mileage or pay-per-mile pricing |
| Buying a home | Opens up home-and-auto bundle discounts |
When frequent shopping does not pay
Switching costs. Mid-term cancellations can carry fees or short-rate refunds in some states, and every switch is paperwork.
Tenure benefits. Accident forgiveness, diminishing deductibles and loyalty credits are often earned over time. If you have one of these, put a dollar value on it before switching for a small saving.
Telematics resets. A good driving score with one insurer does not transfer. You may spend months earning a new one elsewhere.
Quote inaccuracy. Quotes based on incomplete information change after the insurer checks your driving record and claims history. Shopping constantly with rough answers produces noise rather than savings.
Getting quotes does not hurt your credit. Insurers' checks of your credit-based insurance score are not the kind of inquiry lenders see when you apply for a loan.
A hypothetical example
Say you have paid the same insurer for four years. Your six-month premium went from $690 to $745 to $812 to $880 with no claims or tickets. The latest renewal is about 8% higher than the last one, and 28% higher than four years ago. A comparison at identical coverage turns up two quotes around $720 for six months. Switching would save about $320 a year — and the repeated increases suggest checking the market every year, not every four.
Now say the same quotes came back at $860. A $40 difference over six months may not be worth losing accident forgiveness you have already earned. The point of the annual check is the information, not a switch every time.
Key takeaways
- Compare prices at least once a year, three to six weeks before a renewal.
- Insurers change rates on different schedules and weigh the same facts differently, so the cheapest company can change even if you do not.
- Shop immediately after a move, a new car, a new driver, a marriage or divorce, or a violation aging off your record.
- Some insurers offer early-shopper discounts for buying before your current policy expires.
- Count what you would lose — accident forgiveness, tenure credits, a telematics score — before switching for a small saving.
