TL;DR: A wedding for 100 guests in Chicago typically runs $48,000 – $85,000, with most couples landing near $62,000 — roughly $620 per guest. Venue and catering alone usually eat 55–60% of that, and Chicago's downtown and West Loop venues push costs toward the top of the range.
Useful summary
At 100 guests, you're at the hinge point where Chicago venues shift from "intimate restaurant buyout" pricing to full hotel ballroom or loft venue minimums. That changes your math.
Here's what you can expect:
- Budget floor (lean): ~$48,000 — off-peak date (Jan–March or Sunday), neighborhood restaurant or community venue, limited florals, DJ instead of band.
- Realistic middle: ~$62,000 — Saturday in shoulder season, a loft or boutique hotel, full bar, plated dinner, standard photography package.
- Premium: $85,000+ — peak Saturday (May, June, September, October) at a downtown hotel, West Loop industrial venue, or lakefront property with upgraded catering and a live band.
The largest single variable is your venue-plus-catering bundle. Chicago food-and-beverage minimums at downtown hotels commonly start at $20,000–$30,000 for 100 guests before tax and the automatic 24–26% service charge.

Per-guest rule of thumb in Chicago: $480 on the low end, $620 midpoint, $850+ premium.
Local context
Chicago has a few pricing realities that don't show up in national averages:
- The 24–26% service charge. Most Chicago hotels and full-service venues add this to every food and beverage line. On a $25,000 F&B bill, that's an extra $6,000+ — and it's not a tip. Budget for it separately.
- Cook County liquor and sales tax. Combined taxes on food and alcohol in Chicago run about 10.25–11.25%. Suburban Cook, DuPage, and Lake County venues tax lower — a real line-item difference at scale.
- Venue clusters by neighborhood. West Loop and Fulton Market industrial venues (Morgan Manufacturing, Gallery 1028, Ignite Glass) trend $10,000–$18,000 in rental alone. River North and Gold Coast hotels (The Peninsula, Waldorf, Thompson) hit higher F&B minimums. Logan Square, Pilsen, and Avondale restaurants and lofts run noticeably cheaper. Lakefront and Millennium Park-adjacent venues (Chicago Athletic Association, Cafe Brauer, Adler Planetarium) carry a view premium.
- Winter is a real discount. January through mid-March Saturdays can save 20–30% on venue minimums. Chicago couples use this deliberately.
- Weather contingency. Outdoor ceremonies need a tent or indoor backup from late October through April, and even June and September can surprise you with wind off the lake. Build $1,500–$3,500 in if you're planning outdoors.
- Parking and transit. Downtown venues rarely include guest parking; valet packages run $15–$25/car. If most guests are coming from the suburbs, factor shuttles ($1,200–$2,500) or choose a venue near a CTA line.

FAQ
What's the average cost of a 100-guest wedding in Chicago?
Most Chicago couples spend $55,000–$70,000 on a 100-guest wedding, with a median near $62,000. That includes venue, catering, bar, photography, flowers, music, attire, and vendor tips — but not the honeymoon or engagement ring.
How much should I budget for catering alone in Chicago?
Plan on $180–$275 per guest for full-service catering and bar at a standard Chicago venue, or $18,000–$27,500 for 100 guests. Downtown hotels and West Loop venues often have F&B minimums that push you to the high end before you've chosen a menu.
Is it cheaper to get married in the Chicago suburbs?
Usually yes — expect 10–20% savings in suburban Cook, DuPage, or Lake County, driven by lower venue rentals, lower sales tax, and no service-charge-heavy hotel contracts. You'll trade convenience and the skyline backdrop for the savings.
What's the cheapest month to get married in Chicago?
January, February, and early March are the cheapest, with many venues discounting Saturday rates 20–30% and offering weekday or Sunday rates even lower. The tradeoff is weather — plan indoor logistics and warm guest transport.
Do I need a wedding planner for 100 guests in Chicago?
A full planner isn't required, but a month-of coordinator ($1,500–$3,000) pays for itself at the 100-guest scale. Chicago venues often require a day-of contact, and hotel contracts with service charges, taxes, and tasting timelines are easy to misread without one.
How much should I tip Chicago wedding vendors?
On top of the automatic service charge, tip the banquet captain $150–$300, bartenders $50–$100 each if gratuity isn't included, photographers/videographers $100–$200 each optionally, hair and makeup 18–20%, and transportation drivers 15–20%. Build $2,000–$3,500 into your budget for gratuities.
Does the 24% service charge count as the tip?
No. In Illinois, the service charge is a venue fee distributed at the venue's discretion and is not a guaranteed gratuity to staff. Ask your venue in writing how it's allocated, then decide whether to tip the captain and bartenders on top.
