TL;DR: A 100-guest wedding in Ann Arbor typically costs $42,000 – $68,000, with most couples landing around $52,000. Expect roughly 45% of that to go to venue and catering, driven by University of Michigan demand, a short summer/fall peak, and regional per-plate minimums of $110–$165.
Useful Summary
Ann Arbor is a college-town wedding market with a compressed peak season (May through mid-October) and a strong preference for sit-down dinners at historic, campus-adjacent, or rural-chic venues. For 100 guests, you're in the sweet spot where most venues waive small-guest surcharges but still trigger full staffing, rental, and minimum spend requirements.
Plan for:
- A total range of $42,000 – $68,000, depending on venue type (barn vs. museum vs. hotel) and Saturday vs. Friday/Sunday pricing.
- Per-guest all-in cost of roughly $420 – $680, including everything from invitations to the late-night exit.
- A 10–15% contingency line — Ann Arbor vendors book 12–18 months out for prime dates, and late substitutions cost more.
If your number is below $42,000 for 100 guests, you'll need to shift to a Friday, a Sunday, a November–April date, or a non-traditional venue (brewery, restaurant buyout, backyard with tent).

Local Context
Venues you're likely comparing:
- Campus and museum venues (UMMA, Michigan League, Michigan Union): $8,000–$14,000 rental, formal catering, strong Saturday demand from alumni weddings.
- Kerrytown and downtown restaurants (Zingerman's Cornman Farms, Weber's, The Gandy Dancer): often all-inclusive at $180–$240 per person, simplifying 100-guest budgets.
- Rural barns within 30 minutes (Washtenaw and Livingston County): $4,500–$8,500 rental, but add $6,000–$12,000 in tent, restroom trailer, and generator rentals if the space isn't fully built out.
- Ann Arbor hotel ballrooms (Graduate, Kensington Court): food minimums of $12,000–$18,000 for 100 guests, but room blocks and logistics are easier.
What drives local cost up:
- Football Saturdays (September–November): many venues either block the date or charge a premium; hotel blocks near campus can triple in price.
- Graduation weekends (late April, early May): same problem for lodging.
- Short outdoor season: May–October is the only reliable stretch for outdoor ceremonies, so those dates carry a 10–20% peak premium.
What drives it down:
- Friday or Sunday dates save $2,000–$5,000 at most full-service venues.
- Off-season (January–March) can cut total cost by 15–20%, with the tradeoff of weather-driven guest travel risk.
- Using a local caterer with a rental partner (rather than a hotel package) typically saves $1,500–$3,000 at the 100-guest scale.

FAQ
Is $50,000 enough for a 100-guest wedding in Ann Arbor?
Yes, $50,000 is realistic for 100 guests in Ann Arbor if you book a Friday or Sunday, avoid football Saturdays, and pick a venue with in-house catering. You'll have to be deliberate about flowers and live music, but photography, venue, food, and bar will all fit comfortably.
What's the cheapest time of year to get married in Ann Arbor?
January through March is the cheapest window, typically 15–20% below peak pricing. November and early December are the next-best value, though you'll want to avoid Michigan home football weekends in November and the week of Thanksgiving.
How much should I budget for catering alone for 100 guests?
Plan on $130–$220 per guest all-in for food and bar, which works out to $13,000–$22,000 for 100 guests. Plated dinners and full open bars sit at the top of that range; stations, family-style, or beer-and-wine-only packages bring it down.
Do Ann Arbor venues require a wedding planner?
Many full-service venues (museums, campus properties, historic homes) require at least a month-of coordinator, which runs $1,200–$2,500 locally. Hotels and all-inclusive restaurants usually include a venue coordinator, which is not the same thing — their job is the venue, not your timeline or vendors.
How far in advance should I book venues in Ann Arbor?
Book popular Saturday dates 12–18 months out, especially for May, June, September, and October. Off-peak and weekday dates can often be booked 6–9 months ahead, and you'll have more negotiating room on pricing and minimums.
What's the tipping expectation for vendors?
Budget roughly $1,500–$2,500 in tips for a 100-guest wedding: 15–20% for catering staff (if not already in service charge), $50–$200 per person for photographer/DJ/officiant, and $20–$50 per delivery driver or shuttle driver. Check every contract — many Ann Arbor caterers include a 20% service charge that is not a tip.
How much should I set aside for a contingency?
Hold back 8–12% of your total budget — about $4,000–$6,000 on a $52,000 wedding. It covers weather backup (tent sidewalls, heaters), last-minute guest count adjustments, alterations, and the small purchases that always come up in the final two weeks.
