What 7 Factors Do Insurers Use to Determine Car Premiums
Insurers price you mainly on driving record, the car, location, age, credit-based scoring where allowed, coverage, and other drivers.
These seven factors decide what you pay
- Driving record This means accidents and violations on file, and with none yet, insurers can't rate you as proven safe. Ask what counts as a clean record length so you know when yours will start counting.
- The car you drive Repair cost, safety features and theft rates all affect your rate. Before buying, ask an insurer to quote a few specific models so the car doesn't work against you.
- Where you live and park Your rate reflects local accident rates, theft and claims in your area, not just the state. If you're choosing between two addresses, ask how each one prices out.
- Age and experience combined Insurers separate age from years licensed, so an adult new driver is priced differently than a teenager. Ask specifically how they treat new adult drivers, since this varies by insurer.
- Coverage and deductible choices Higher deductibles and narrower coverage lower your premium but raise what you pay after a claim. Pick the balance based on what you could cover yourself, not just the lowest quote.
A new adult driver shopping for a first policy
Mara moved to a city where she finally needed to drive and got her license well into adulthood. When she requested quotes, the first insurer treated her almost like a teenager, pricing her on inexperience alone despite her age. She didn't argue the number. Instead she asked the agent directly which of the seven factors were hurting her most, and learned her zero-history record and her choice of a sportier used car were doing most of the damage.
She changed what she could control. She picked a different, more ordinary car with a better safety record, raised her deductible slightly since she had savings to cover it, and asked about being added to a family member's policy temporarily to borrow some household history. The combination lowered her quote noticeably compared to the first one. She kept shopping every so often as her own driving record grew, since that factor would keep improving regardless of what she did elsewhere. After a while on the road, her record alone carried more weight than any of the other adjustments she'd made at the start.
Compare quotes now, using the factors you control, like the car and coverage, while your record builds.
Whether you optimize these factors before buying a policy
If you do
You compare how car choice, deductible and address shift your quote before committing to anything. You catch costly mismatches early, like a car that prices badly for someone without a long record. You walk into a policy knowing exactly why the number is what it is, and what would lower it later.
If you don't
You accept the first quote without knowing which factor drove the price up. You might keep a car or address that's quietly costing you more than it needs to. You lose months or years before realizing a small change, like adjusting coverage, could have lowered your rate the whole time.
Why these seven factors carry the weight they do
Insurers price risk, not people. Each factor is a stand-in for how likely a claim is and how expensive it would be. Driving record is the strongest signal because it's the most direct evidence of behavior, but when that evidence doesn't exist yet, insurers fall back on the next best indicators, like age, the car, and location, which is exactly why a new driver in their thirties or forties can face pricing that feels disconnected from who they actually are.
The car and location factors work the same way almost everywhere, because repair costs, theft rates and local accident patterns are measurable facts insurers can check. What varies is how much weight each insurer gives to age versus experience, and whether factors like credit-based scoring are used at all, since some states restrict or ban it. This is worth asking about directly, because two insurers can look at the same new driver and price them very differently based on which factors they lean on most.
Coverage and deductible choices are different from the other factors because they're the one lever fully in your control. Everything else describes you or your situation, but your deductible and coverage limits are decisions you make, and they interact with the other six factors. A driver with no history and a cheap, practical car can often offset some of the inexperience penalty by choosing a higher deductible, since it signals less exposure for the insurer.
The case where this all works differently is when someone is added to another driver's policy instead of buying their own. In that setup, the policyholder's history and factors often outweigh the new driver's lack of record, which is why that option comes up so often for people building their driving record from scratch.
Will my rate actually go down once I build a driving record?
Yes, in almost every case, because driving record is the factor insurers trust most once it exists. A stretch of claim-free driving tends to move your rate more than any single change you make elsewhere, including switching cars or adjusting your deductible.
The timeline isn't fixed and depends on the insurer, since some reward even a short clean stretch while others wait longer before adjusting your price meaningfully. Ask any insurer you're considering how they treat a growing record over time, and whether they reward it with automatic reviews or only if you ask. If you're currently on someone else's policy, ask what happens to your pricing once you move to your own, since your personal record should start counting at that point even though you weren't the one named on the paperwork before.
