7 Ways to Lower Your Car Insurance Premium

How your rate gets set, and where you have control

Your car insurance premium is built from factors the insurer can see (your driving record, the car itself, where you live) and factors you control (how much coverage you buy, what deductible you choose, how you bundle policies). Lowering your rate means either changing the controllable pieces or shopping for an insurer that weights the unchangeable ones differently. Most people find their biggest savings by raising their deductible, bundling home and auto, or switching insurers after a rate increase — not by waiting for their record to improve.

The math is straightforward: an insurer quotes you a rate based on risk. If you've had an accident, that's baked in for three to five years depending on your state. But if you haven't had one, or if you're willing to accept more financial risk yourself by raising your deductible, you can move the needle when ready. The catch is that every insurer weights these factors differently, so a rate that's high at one company might be standard at another.

Key Takeaways

• Raising your deductible from $500 to $1,000 typically cuts your collision and comprehensive premiums by 15 to 30 percent, depending on your insurer and state.
• Bundling your car and home insurance with the same company usually saves 15 to 25 percent on your auto premium alone.
• Shopping for quotes every two to three years is the single most effective way to lower your rate, because insurers raise prices for existing customers faster than they offer them to new ones.
• Discounts for good driving, low mileage, and safety features exist at most insurers but vary widely — ask about each one before you commit.
• Removing coverage you don't need (like collision on a paid-off car worth less than $5,000) can lower your premium, but leaves you exposed if you cause an accident.

Raise your deductible if you have savings to cover it

Your deductible is the amount you pay out of pocket when you file a claim. The higher your deductible, the lower your premium, because the insurer is taking on less risk. Moving from a $500 deductible to $1,000 typically saves 15 to 30 percent on collision and comprehensive coverage — the parts that cover damage to your own car. The exact savings depend on your insurer, your state, and your car's value.

The trade-off is real: if you cause an accident and your car needs $3,000 in repairs, you'll pay $1,000 out of pocket instead of $500. Only raise your deductible if you have that money in savings and won't need to borrow it. If you're living paycheck to paycheck, a lower deductible protects you from a financial crisis when an accident happens. If you have an emergency fund, a higher deductible is usually the fastest way to cut your premium.

Some insurers let you set different deductibles for collision and comprehensive — for example, $500 for comprehensive (theft, weather, vandalism) and $1,000 for collision (accidents). This middle ground can save money without leaving you exposed to the most common claims.

Bundle your car and home insurance

Most insurers offer a discount when you buy car and home insurance from the same company. This discount typically ranges from 15 to 25 percent on your auto premium, though the exact amount varies by insurer and state. The discount is real money — not a marketing trick — because the insurer saves on billing and customer service costs when they manage both policies.

To use this strategy, you need to own a home or rent and have renters insurance. If you're a renter without a policy, bundling won't help you. If you own a home, call your current homeowners insurer and ask for a quote on car insurance, or call a major multi-line insurer like State Farm, Allstate, or GEICO and ask what the bundled rate would be. Compare that bundled quote to your current car insurance rate — sometimes the bundled rate is lower even if the home insurance is higher, because the discount is that large.

Bundling also simplifies your life: one renewal date, one customer service number, and one bill. If you move or change coverage, you update it in one place.

Shop for quotes every two to three years

Insurers raise rates for existing customers faster than they offer rates to new ones. A customer who's been with the same company for five years often pays 20 to 40 percent more than a new customer with the same driving record and car. This is called price optimization, and it's legal in most states. The only way to fight it is to get quotes from other insurers and switch when you find a better rate.

Set a calendar reminder to shop for quotes every two to three years, or when ready after any life change: a move, a new car, a birthday (age affects rates), or a change in your driving habits. When you call or visit an insurer's website, have your driver's license, current insurance card, and vehicle registration ready. Most quotes take 10 to 15 minutes online or over the phone. You don't have to switch — sometimes calling your current insurer and mentioning a competitor's quote is enough to get them to lower your rate.

When comparing quotes, make sure the coverage limits and deductibles are the same across all of them. A quote that looks cheaper might have lower liability limits, which leaves you exposed if you cause a serious accident. Liability coverage pays for damage you cause to other people's property or injuries — this is the one place where going cheap can be expensive.

Ask about discounts you might may have access to for

Most insurers offer discounts that can reduce your premium by 5 to 15 percent each. Common ones include good driver discounts (usually for three to five years without an accident or violation), low-mileage discounts (if you drive under 7,500 miles per year), safety feature discounts (for anti-theft devices or advanced braking systems), and bundling discounts (covered above). Some insurers also offer discounts for completing a defensive driving course, paying your premium in full instead of monthly, or using their mobile app to track your driving.

The catch is that these discounts vary widely by insurer and state. One company might offer a 10 percent good driver discount while another offers 5 percent. Some insurers stack discounts (you can get multiple at once) and some don't. When you get a quote, ask the insurer to list every discount you may have access to for and what each one saves you. This is the only way to know whether a quote is actually competitive.

Defensive driving courses are worth considering if you've had a recent accident or violation. Many insurers will give you a discount for completing one, and some states allow you to remove a minor violation from your record if you pass the course. The course usually costs $20 to $50 and takes a few hours online.

Remove coverage you don't need, carefully

If your car is paid off and worth less than $5,000, you might consider dropping collision and comprehensive coverage — the parts that pay to repair your own car. Liability coverage (which pays for damage you cause to others) is required by law in every state, but collision and comprehensive are optional if you own the car outright. Dropping them can save $30 to $100 per month depending on your car and insurer.

The risk is that if you cause an accident, you'll pay for repairs yourself. If your car is worth $4,000 and you cause $3,000 in damage, you've saved money over time. If you cause $8,000 in damage, you've lost money and might not be able to afford repairs. This decision makes sense only if you have savings to cover a major repair or replacement, and you're comfortable driving an older car that might not be worth fixing.

Never drop liability coverage. It's required by law, and it protects your personal assets if you cause a serious accident. If you injure someone and they sue, liability coverage pays their medical bills and legal judgment — up to your policy limit. If you don't have enough coverage and lose a lawsuit, a creditor can garnish your wages for years.

Pay attention to how you pay

Some insurers charge a fee if you pay monthly instead of paying your full premium upfront. This fee is usually $0 to $10 per month, but it adds up: paying monthly instead of annually can cost $50 to $120 per year. If you can afford to pay your premium in full, do it. If you can't, ask your insurer whether they charge a payment plan fee — some don't.

Automatic payments (setting up your bank account to pay automatically each month or year) sometimes may have access to for a small discount, usually 1 to 3 percent. It's not a huge savings, but it's information programs if you're already paying monthly. Set it up when you buy the policy and you'll never miss a payment.

Paperless billing (receiving your documents by email instead of mail) also sometimes qualifies for a discount, usually 1 to 2 percent. Again, it's small, but worth asking about.

Understand what you can't control

Some factors that affect your rate are outside your control: your age, your driving record, your location, and your car's make and model. A 19-year-old will always pay more than a 45-year-old with the same record, because young drivers have more accidents statistically. An accident or violation stays on your record for three to five years depending on your state, and you can't remove it early. If you live in a high-crime urban area, you'll pay more than someone in a rural area with the same car and record.

What you can do is understand how these factors affect your rate so you're not surprised. If you're shopping for a car, ask the insurer to quote you on a few models before you buy — some cars cost significantly more to insure than others. If you've had an accident, know that your rate will come down automatically after three to five years without another one. If you're moving, get a quote in your new location before you move so you know what to expect.

Frequently Asked Questions

How much can I save by switching insurers?

Savings vary widely, but the average person who shops around saves $400 to $800 per year. Some people save more, some less — it depends on your driving record, car, location, and which insurers you compare. The only way to know is to get quotes from at least three insurers.

Will my rate go up if I file a claim?

Usually yes, but it depends on your insurer and state. Most insurers raise rates after a collision claim, though the increase varies. Comprehensive claims (theft, weather, vandalism) often don't raise your rate, or raise it less than collision claims. Ask your insurer what their policy is before you file.

Does my credit score affect my car insurance rate?

Yes, in most states. Insurers use a credit-based insurance score (different from your credit score) to help set rates. A lower score usually means a higher rate. Paying bills on time and keeping credit card balances low can improve your score over time.

Can I lower my rate by driving less?

Yes, if your insurer offers a low-mileage discount. Most insurers define low-mileage as under 7,500 miles per year. If you work from home or use public transit, ask your insurer whether this discount applies to you. Some insurers also offer usage-based programs that track your driving and give discounts for safe driving habits.

What's the difference between liability and collision coverage?

Liability pays for damage you cause to other people's property or injuries — it's required by law. Collision pays to repair your own car if you cause an accident. Liability protects others; collision protects your car. You need liability; collision is optional if your car is paid off and you have savings.
