South Carolina car insurance costs vary more by city and driver profile than most residents expect. The statewide average for full coverage sits around $148 to $256 per month depending on which 2026 data source you use — a spread that reflects real differences in how data sources construct their sample profiles. What matters more than the statewide average is where your rate falls within that range, and what factors give you room to lower it.
The good news going into 2026: South Carolina implemented a series of regulatory changes in 2025 that contributed to an average 11% rate decrease — one of the largest single-year reductions in the country, according to InsuranceQuotes.com's analysis. The market is more competitive now than it has been in several years, which makes this a good time to compare your current policy against what else is available.
Average car insurance cost in SC (2026 data)
For full coverage car insurance in South Carolina, NerdWallet's April 2026 analysis shows a statewide average of $2,508 per year. MoneyGeek's 2026 data shows full coverage ranging from $62 to $139 per month among major carriers. The Zebra's analysis puts the statewide average at $1,361 per year — reflecting a lower-coverage profile in their sample. Insurify's 2026 data puts full coverage at $255 per month, or $3,063 annually.
The differences reflect different coverage assumptions and sample profiles. The relevant takeaway is that the spread between the cheapest and most expensive carrier for the same South Carolina driver can easily run $50 to $100 per month or more — which is why comparing quotes matters more than knowing the state average.
For minimum coverage (South Carolina's required 25/50/25 liability plus mandatory UM/UIM), the statewide average runs $78 to $174 per month depending on the source, with NerdWallet showing $721 per year and InsuranceQuotes showing $90 per month.
Insurance rates by city: Myrtle Beach, Conway, Columbia
Rates vary meaningfully across South Carolina's cities based on accident frequency, traffic density, vehicle theft rates, and storm exposure.
Myrtle Beach and the Grand Strand: Coastal areas carry higher rates than inland markets because of hurricane and tropical storm exposure, which affects comprehensive coverage costs. The combination of year-round tourist traffic, seasonal population surges, and beach-adjacent commuting patterns also affects accident frequency data. Myrtle Beach drivers tend to pay above the state average for comparable coverage.
Conway: As an inland market without the coastal premium and with lower traffic density than Myrtle Beach, Conway typically prices more competitively than the Grand Strand. Horry County as a whole sees elevated insurance costs during peak tourist months, which can affect rate calculations even for inland residents.
Columbia: The state capital sits inland with different risk characteristics — higher traffic density than the coast, but different storm exposure. Columbia area rates tend to track closer to the state average.
North Charleston: Consistently the most expensive major South Carolina market at around $151 per month for full coverage according to MoneyGeek's 2026 data. Port city traffic, commercial truck volume, and elevated vehicle theft rates drive rates 16% above the state average.
Greer and Aiken: Consistently among the lowest-rate markets in the state. Greer runs around $115 per month for full coverage, and Aiken around $180 per month, reflecting lighter traffic, lower urban density, and lower crime rates compared to coastal and port city markets.
Factors that impact your SC auto premium
Driving record: The most direct factor. A DUI can spike South Carolina premiums by 50% to 100%, reaching over $2,075 annually. A single speeding ticket adds meaningfully to your rate. Most surcharges taper off after three years, making the three-year mark after any serious violation worth targeting for a re-shop.
Credit score: South Carolina allows insurers to use credit-based insurance scores. Drivers with poor credit can pay significantly more than those with good credit for the same coverage with the same driving history. Improving your score is a long-term rate reduction strategy that doesn't require changing your coverage.
Age: Teen drivers in South Carolina average around $4,456 to $6,000 or more per year — more than double the state average. Rates fall substantially through the 20s and tend to reach their lowest point in the 50s.
Vehicle: Higher-value vehicles and certain models with elevated theft rates carry higher comprehensive premiums. Coastal South Carolina's hurricane exposure makes comprehensive coverage particularly relevant — tropical storm and hurricane season damage to parked vehicles is a real risk along the Grand Strand.
SC vs national average costs
South Carolina's full coverage average of $2,508 to $3,063 per year compares to the national average of roughly $2,014 to $2,490 depending on the source. For minimum coverage, South Carolina's $534 to $1,083 per year compares to a national minimum average of around $622 per year. South Carolina runs above the national average overall, though the 2025 rate decreases narrowed that gap somewhat.
One driver of SC's elevated rates is the mandatory uninsured motorist requirement. Unlike states where UM/UIM is optional, South Carolina requires it at the same 25/50/25 minimums as liability coverage, which adds to base premium costs but also provides genuinely valuable protection given that a meaningful percentage of South Carolina drivers carry inadequate or no coverage.
How to get cheaper car insurance in SC
Compare quotes from multiple carriers. The most expensive major carrier in MoneyGeek's 2026 analysis costs more than double the cheapest for comparable coverage. That spread is the single best argument for running a real comparison rather than auto-renewing.
Bundle home and auto with the same carrier. Most South Carolina insurers offer 10% to 25% multi-policy discounts. On a $2,500 annual auto premium, a 15% bundle discount saves $375 per year.
Maintain a clean driving record. Three years without at-fault accidents, DUIs, or major violations opens up good driver discounts with most carriers and makes you eligible for preferred pricing tiers.
Ask about every available discount. Defensive driving course, low mileage, anti-theft devices, pay-in-full, and paperless billing discounts all stack and are frequently overlooked.
