The fastest ways to cut your car insurance cost

The most direct ways to lower your premium are to raise your deductible, drop coverage you don't need, ask about discounts you're not using, and shop your policy to other insurers every two to three years. Most people save the most by switching carriers — the average driver who gets three quotes saves several hundred dollars annually. After that, bundling home and auto policies, maintaining a clean driving record, and taking a defensive driving course each produce real reductions, though the size varies by insurer and your location.

The changes that cost you nothing upfront — like asking about discounts or switching insurers — should come first. The changes that trade lower premiums for higher out-of-pocket costs if you have an accident (raising your deductible, dropping collision coverage) should come only after you understand what you're giving up.

Key Takeaways

  • Shopping your policy to at least two other insurers every two to three years typically saves more money than any single change to your current policy.
  • Raising your deductible from $500 to $1,000 usually cuts your premium by 15 to 30 percent, but you pay that full amount out of pocket if you have an accident.
  • Bundling your car and home insurance with the same company often saves 15 to 25 percent on your car premium alone.
  • Discounts for good driving records, defensive driving courses, low mileage, and paperless billing exist at most insurers but are not automatic — you must ask.
  • Dropping collision or comprehensive coverage makes sense only if your car is worth less than 10 times your annual premium for that coverage.

Shop your policy to other insurers every two to three years

This single step saves most people more money than any other change. Insurance companies use different formulas to price risk, so the cheapest option for you today may not be the cheapest in two years. Getting quotes from at least two competitors takes 15 to 30 minutes and costs nothing.

When you get quotes, use the same coverage limits and deductibles across all three quotes so you're comparing the same thing. Many insurers offer online quote tools that don't require a phone call. If you find a cheaper option, contact your current insurer and ask if they'll match it — some will, and you avoid the hassle of switching. If they won't, switching is straightforward: buy the new policy, confirm the start date overlaps with your current one by at least a day, then cancel the old policy.

The best time to shop is when your policy renews, because you're already thinking about insurance. But you can shop anytime — there's no penalty for switching mid-term, though you may lose a small refund if you cancel early.

Raise your deductible if you have emergency savings

Your deductible is the amount you pay out of pocket before insurance covers the rest of a claim. Raising it from $500 to $1,000 typically cuts your collision and comprehensive premiums by 15 to 30 percent. Raising it to $2,500 cuts them further, though the savings per dollar of deductible increase shrink as you go higher.

This trade-off only makes sense if you have cash set aside to cover the deductible without going into debt. If a $1,000 accident would force you to use a credit card, keep your deductible at $500. The premium savings aren't worth the cost of interest on debt. If you do have savings, a higher deductible is a safe way to lower your premium because you control when and whether you use it — you can choose not to file a small claim and keep your rate from going up.

Check what your insurer charges for each deductible level before you decide. The savings vary widely between companies and between regions, so the math matters more than the general rule.

Bundle your car and home insurance

Insuring your car and home with the same company usually saves 15 to 25 percent on your car premium, though the exact discount varies by insurer and location. Some companies offer the discount automatically; others require you to ask. Call your homeowners insurer and ask what they charge for auto insurance bundled with your current policy, then compare that bundled quote to quotes from other companies.

Bundling is worth considering even if the bundled quote isn't the absolute cheapest option, because the combined savings on both policies may beat the total cost of splitting them between two insurers. Use a calculator or spreadsheet to add up your total annual cost (home plus auto) under each scenario before you decide.

If you rent rather than own, bundling renters insurance with auto insurance produces similar discounts at most carriers.

Ask about discounts you're not using

Most insurers offer discounts for good driving records, defensive driving courses, low annual mileage, paperless billing, automatic payment, and bundling. Many also offer discounts for safety features like anti-theft devices or collision-avoidance technology. These discounts are not automatic — you have to ask, and you may have to provide proof (like a certificate from a defensive driving course or a current mileage reading).

Call your insurer or log into your online account and ask which discounts you currently have and which ones you don't. The defensive driving discount typically requires you to take an online course that takes three to four hours and costs $15 to $50. The course doesn't lower your license points or affect your driving record — it's purely for the insurance discount. Some insurers offer it free to policyholders.

Low-mileage discounts usually apply if you drive fewer than 7,500 to 10,000 miles per year, though the threshold varies by insurer. If you work from home or use public transit most days, ask whether you may have access to.

Drop collision or comprehensive coverage if your car is old

Collision coverage pays for damage to your car from an accident. Comprehensive coverage pays for damage from theft, weather, vandalism, or hitting an animal. Neither is required by law (liability is), so you can drop them if you choose. But dropping them makes financial sense only if your car is worth less than 10 times what you pay annually for that coverage.

For example, if your car is worth $5,000 and collision coverage costs $600 per year, you're paying 12 percent of the car's value annually for coverage. If you have an accident, you pay your deductible and insurance covers the rest — but if the car is totaled, you get $5,000 minus your deductible. If you drop the coverage and have an accident, you pay the full repair cost or the car's value if it's totaled. The math only favors dropping coverage if you can afford to replace the car out of pocket.

Check your car's current market value using Kelley Blue Book or NADA Guides, then divide that by your annual collision and comprehensive premiums. If the result is less than 10, keep the coverage. If it's more than 10, dropping it will lower your premium, though you're taking on the risk of a large out-of-pocket cost.

Maintain a clean driving record

Accidents and traffic violations raise your premium for three to five years, depending on your insurer and your state. A single at-fault accident can raise your rate by 20 to 40 percent. A speeding ticket or other moving violation typically raises it by 10 to 30 percent. The impact varies widely by insurer, so if you have a violation or accident, getting quotes from other companies may reveal one that penalizes it less heavily than your current insurer.

If you received a ticket, some states allow you to take a defensive driving course to have the ticket dismissed or to reduce the impact on your insurance rate. Ask your insurer whether they offer a rate reduction for completing a course, even if the ticket wasn't dismissed. Some do, and some don't.

The best way to keep your rate low is to avoid accidents and violations. If you're a safe driver, make sure your insurer knows — ask about good-driver discounts and confirm you're receiving them.

Understand what you're trading off before you cut coverage

Lowering your premium by dropping coverage or raising your deductible shifts risk from the insurance company to you. That's a reasonable trade if you have savings to cover the risk, but it's a bad trade if you don't. Before you make any change that increases your out-of-pocket costs, ask yourself: could I pay this amount out of pocket without going into debt?

If the answer is no, focus on the changes that don't shift risk: shopping for a better rate, bundling, asking about discounts, and taking a defensive driving course. These lower your premium without making you more vulnerable to financial hardship if you have an accident.

Frequently Asked Questions

How much can I save by switching insurance companies?

The amount varies widely based on your age, driving record, location, and the type of car you drive. On average, drivers who get three quotes save several hundred dollars per year compared to staying with their current insurer. The only way to know what you can save is to get quotes from at least two other companies using the same coverage and deductibles.

Will my rate go up if I raise my deductible?

No — raising your deductible lowers your premium. You pay less each month or year, but you pay more out of pocket if you have an accident. The trade-off only makes sense if you have savings to cover the higher deductible without borrowing.

Do I have to take a defensive driving course to get the discount?

Most insurers require you to complete an approved course to receive the discount. The course is usually online, takes three to four hours, and costs $15 to $50, though some insurers offer it free. The discount typically lasts three years, so you'd need to retake the course to renew it.

What happens to my rate if I have an accident?

An at-fault accident typically raises your rate by 20 to 40 percent for three to five years. The exact impact depends on your insurer and your state. If you have an accident, get quotes from other insurers — some may penalize it less heavily than your current company.

Should I drop comprehensive coverage to save money?

Only if your car is worth more than 10 times what you pay annually for comprehensive coverage. If your car is worth $8,000 and comprehensive costs $600 per year, the ratio is about 13, so dropping it makes financial sense. If the ratio is less than 10, keep the coverage — the premium savings aren't worth the risk.
