Renting a car in South Carolina typically costs between $50 and $120 per day on average. The final price is highly variable, influenced by seasonal demand, rental location, vehicle type, rental duration, and included extras. For budget , expect a compact car to average $55-$90 daily, while a standard SUV often ranges from $90-$140 daily.
Your choice of pickup location significantly impacts cost. Renting from a major airport like Charleston (CHS) or Myrtle Beach (MYR) is convenient but often includes premium fees and taxes. Renting from a downtown or suburban branch of the same company can be 15-30% cheaper. Summer and during major events (like the Carolina Cup or Charleston Wine + Food Festival), daily rates can double compared to the winter off-season.
The rental duration is another key factor. Weekly rentals usually offer a lower average daily rate than three separate two-day rentals. An economy car might rent for $75/day, but a weekly rate could be around $350, bringing the effective daily cost down to $50.
Beyond the base rate, mandatory fees and optional add-ons are crucial to your budget. These include state and local taxes, an airport concession fee if applicable, and a vehicle license fee. A young driver fee (for drivers under 25) can add $25-$35 per day. Damage waivers (CDW/LDW) or supplemental liability insurance can easily add $25-$50 daily. Refueling policies can also add a substantial charge if you return the tank less than full.
To secure the best rate, book at least two to three weeks in advance, especially for peak travel. Compare prices across both major brands and budget operators. Be decisive with your insurance choices—check your personal auto policy and credit card benefits for coverage before accepting the rental company's offerings. Declining unnecessary extras like pre-paid fuel or GPS (use your smartphone) can lead to significant savings. Always read the rental agreement thoroughly to understand mileage limits, additional driver policies, and cancellation terms.

I was just looking at this for my trip to Charleston next month. I was surprised—prices shift constantly. A basic car showed as $58 a day when I looked on a Tuesday, but by the weekend, the same car was $89. My takeaway? Don’t wait until the last minute. I’m booking my rental almost as soon as I book my flight. Airport rentals are so much easier with luggage, but I checked a city location too, and it was about $20 cheaper per day. I’m still deciding if the Uber ride downtown is worth that saving.

Here’s the real deal from someone who’s done this drive a dozen times. Forget the sticker price. The advertised $53 a day is a ghost you’ll rarely catch. I budget for $80 to $100 a day, all-in, for a midsize. Myrtle in July? That’s the premium zone. Go in November, and you’ll breathe easier. Always, and I mean always, skip the counter insurance if your own car insurance or gold-level credit card covers rentals. They’ll push it hard. Oh, and never get the tank filled by them. Find a gas station near the return lot. It’s the oldest trick in the book, but folks still get caught.

We needed a minivan for our family of five last summer, traveling into Greenville. The price difference between car types was huge. A standard car was quoted around $75/day, but the minivan we needed jumped to $135. We saved nearly $200 by adjusting our trip by just two days—renting from Wednesday to Wednesday instead of a weekend start. We also compared every company. The big names were easier, but a well-reviewed local agency had a similar van for $30 less per day. It paid to dig a little deeper. For families, the size and the weekly rate are where you find the real value.

My friend is a coastal road trip from Hilton Head to Charleston and asked me for budget advice since I did a similar loop. I told him the daily rate is just the starting point. You have to build a total trip budget. I explained how picking up at the Savannah airport (just over the state line) was cheaper than starting in Hilton Head itself for my rental. I warned him about the one-way drop fee if you plan to return the car in a different city—that can be a $150+ surprise. My main advice was to book something with free cancellation now to lock in a rate, and then keep checking for price drops. I found monitoring rates every few days leading up to my trip saved me about $17 a day.
