You open your renewal notice, and the number is higher than last year — again. Or you shop around and get quotes that vary by hundreds of dollars for the same car. What exactly is going on?
The truth is, car insurance pricing is not random. Every number you see is the result of a complex formula insurers use to predict how likely you are to file a claim. The higher the risk they calculate, the higher your premium. But here's what most people don't realize: many of those factors are within your control.
At Mauldin Insurance Group in Lexington, SC, we help drivers across the Midlands and the entire state understand what drives their auto insurance costs — and find better rates. Here are the ten most important factors insurers use when calculating your premium.
1. Your Driving Record
This is the single biggest factor. Insurers look at your history for the past three to five years, including:
- At-fault accidents
- Speeding tickets and moving violations
- DUI or DWI convictions
- Reckless driving citations
A single at-fault accident can raise your premium by 30–50% at renewal. A DUI can double it — or cause your insurer to non-renew your policy entirely. Conversely, a clean record is one of the most powerful discounts available.
South Carolina drivers with no violations for three or more years are often eligible for safe driver discounts that can reduce premiums significantly.
2. Your Age and Driving Experience
New drivers — especially teenagers — pay the highest rates because they have the least experience and the highest statistical risk of accidents. Premiums typically peak for drivers under 25 and then decrease steadily through middle age.
Drivers in their 50s and early 60s often enjoy the lowest rates of their driving careers. After age 70, rates may begin to rise again as reaction times and vision can become factors.
If you have a teen driver in your household, talk to us about the best way to add them to your policy. There are strategies that can reduce the impact significantly.
3. Your Vehicle — Make, Model, and Year
Not all vehicles are priced equally to insure. Insurers look at:
- Repair and replacement costs — luxury and imported vehicles cost more to fix
- Safety ratings — vehicles with strong crash test scores often cost less to insure
- Theft rates — some models are stolen far more frequently than others
- Engine size — high-performance vehicles are considered higher risk
A compact sedan with strong safety ratings will almost always be cheaper to insure than a sports car or a large SUV of similar value. If you're shopping for a new vehicle, it's worth getting insurance quotes before you buy — the difference can be significant.
4. How Much You Drive
Insurers calculate your annual mileage because more time on the road means more exposure to accidents. If you drive fewer than 7,500 miles per year, you may qualify for a low-mileage discount.
Remote workers and retirees who drive infrequently should make sure their insurer has their mileage correct. Overestimating can cost you money you don't need to pay.
5. Where You Live
Your zip code matters — a lot. Insurers evaluate:
- Local accident rates and traffic density
- Vehicle theft rates in your area
- Weather-related claim patterns
- How often uninsured drivers are on the road nearby
In South Carolina, rural areas generally have lower premiums than urban and suburban corridors. Lexington County rates tend to be moderate compared to densely populated areas like downtown Columbia or North Charleston. That said, rates can vary significantly even between zip codes a few miles apart.
6. Your Credit Score (in States That Allow It)
South Carolina is among the majority of states that allow insurers to use credit-based insurance scores when calculating premiums. Insurers have found a strong statistical correlation between credit history and the likelihood of filing claims.
This is not the same as your FICO score, but it's influenced by similar factors — payment history, amount of debt, and length of credit history. Improving your credit over time can meaningfully lower your insurance costs.
| 💡 Quick Tip If your credit score has improved significantly since your last renewal, ask your agent to re-run your rate. Many insurers will recalculate mid-term or at renewal with updated credit data. |
7. Your Coverage Levels and Deductibles
The coverage you choose directly controls your premium. South Carolina requires drivers to carry minimum liability limits, but most drivers benefit from carrying more.
Key coverage decisions that affect your rate:
- Liability limits — higher limits cost more but protect you far better
- Comprehensive and collision — optional but required if you have a loan
- Deductible amounts — choosing a $1,000 deductible instead of $500 lowers your premium but increases your out-of-pocket cost after a claim
- Uninsured motorist coverage — highly recommended in SC given the rate of uninsured drivers
Many drivers are over-insured on older low-value vehicles (paying for comprehensive and collision on a car worth $3,000) and under-insured on liability where the real financial risk lives. A quick policy review can often find savings.
8. Your Claims History
Even if you weren't at fault, a history of multiple claims can raise your rates. Insurers track claims through CLUE (Comprehensive Loss Underwriting Exchange) — a national database that records auto and home insurance claims for up to seven years.
If you've had two or more claims in the past few years, expect to pay more regardless of fault. Frequent claimants are viewed as higher-risk policyholders.
9. Marital Status
Married drivers statistically file fewer claims than single drivers, and many insurers factor this into their pricing. The discount varies by company, but it's real. If you've recently married, make sure your insurer has updated your status.
10. Discounts You Qualify For
Discounts can dramatically offset the factors above. Common discounts available to South Carolina drivers include:
- Multi-policy discount (bundling auto with home or renters insurance)
- Safe driver discount (no violations for 3+ years)
- Good student discount (for full-time students with a B average or better)
- Defensive driving course completion
- Low mileage discount
- Vehicle safety features (anti-lock brakes, lane departure warning, etc.)
- Affinity group discounts (military, first responders, certain employers)
Many drivers never ask about discounts — and leave real money on the table. When we shop your coverage, we make sure every applicable discount is applied.
What Can You Actually Do to Lower Your Rate?
Based on the factors above, here are the most impactful steps SC drivers can take:
- Keep your driving record clean — even one ticket can cost you more than the fine itself over three years of higher premiums
- Bundle your auto and home insurance — this is typically the largest single discount available
- Raise your deductible if you have savings to cover it — moving from $500 to $1,000 often saves 10–15%
- Improve your credit over time — this compounds with every renewal
- Shop your coverage every two to three years — loyalty rarely pays in auto insurance
- Tell your agent about life changes — marriage, moving, retiring, buying a newer safer car
