A 100-guest wedding in South Carolina typically runs $32,000 – $58,000 all-in, with most couples landing near $42,000 — about $420 per guest. Coastal venues in Charleston push the upper end; Upstate and Midlands weddings often come in 20–30% lower.

Useful summary

You're planning for 100 guests in a state where the wedding market is split: Charleston and Hilton Head sit near national averages (or above), while Greenville, Columbia, Aiken, and Myrtle Beach run noticeably cheaper. Catering and venue together will eat 45–55% of your budget — that's where the real decisions are.

Local context

Charleston is the price-setter. Downtown venues (William Aiken House, Lowndes Grove, Cannon Green, Gadsden House) typically run $8,000–$15,000 for site fees alone, before catering minimums of $20,000+. Plantation venues 20–40 minutes out (Magnolia, Boone Hall, Legare Waring House) sit in the same range but bundle more. Expect to add transportation if your guests are staying downtown.

Hilton Head and Kiawah are resort-driven. Sea Pines, The Sanctuary, and Palmetto Bluff push 100-guest budgets to $55,000–$80,000 once F&B minimums and resort fees are in. Off-season (November–February) cuts that 20–30%.

Greenville and the Upstate are the value play. Venues like The Old Cigar Warehouse, Zen, and Larkin's Cabaret Room run $4,000–$7,000 site fees, and catering markets are competitive. A 100-guest Greenville wedding at $32,000–$38,000 is very achievable.

Columbia, Aiken, and Beaufort sit in the middle: $35,000–$45,000 covers a polished day with a local barn, historic home, or country club.

Climate matters. June–September humidity plus afternoon thunderstorms make tented outdoor receptions risky without a hard backup — tents with sidewalls and AC run $4,000–$8,000 extra. Hurricane season runs June 1 – November 30; ask about cancellation policies, especially coastal.

FAQ

What's a realistic budget for 100 guests in Charleston specifically?

Plan for $45,000 – $65,000 for a Charleston wedding with 100 guests at a downtown or plantation venue, peak season, Saturday. The same wedding on a Friday in November typically lands $8,000–$12,000 lower. Resort weddings on Kiawah or Isle of Palms run higher, $55,000–$80,000.

How much should I budget for catering for 100 guests in South Carolina?

Expect $110–$200 per guest for full-service plated or buffet catering, including staff and rentals — so $11,000–$20,000 total. Lowcountry boil and BBQ-style spreads from local caterers can drop that to $75–$95 per guest if your venue allows outside food.

Do I need a wedding planner for a 100-guest South Carolina wedding?

A month-of coordinator ($1,200–$2,500) is the minimum we recommend at this guest count — venue staff are not your advocates, and 100 guests is enough complexity that something will go sideways without one. Full-service planning ($5,000–$10,000+) makes sense for destination couples planning Charleston or Hilton Head from out of state.

What's the cheapest month to get married in South Carolina?

January, February, and August are the lowest-demand months statewide. Venues frequently discount site fees 15–30%, and top photographers are more available. August is hot and humid statewide; January coastal weddings are mild (50s–60s) and a strong value play.

How much does a 100-guest open bar cost in South Carolina?

Budget $35–$70 per guest for a 4–5 hour open bar — so $3,500–$7,000 total. Beer and wine only runs $20–$35 per guest. South Carolina law requires licensed bartenders for any served alcohol, and most venues require liability insurance, which is usually bundled into the bar package.

What's the South Carolina marriage license cost and process?

A South Carolina marriage license costs $25–$110 depending on the county (Charleston County is $50), and there is a 24-hour waiting period after application before it's issued. Both parties must apply in person at the Probate Court; the license is valid statewide and never expires once issued.

Can I do a 100-guest South Carolina wedding for under $25,000?

Yes, but you'll need to make trade-offs: Upstate or rural venue ($2,000–$4,000), buffet or food-truck catering ($60–$80/guest), DJ instead of band, digital invitations, friend officiant, and a Friday or Sunday date. A $22,000–$25,000 wedding for 100 in Greenville, Aiken, or Anderson is realistic with disciplined choices.
