Useful summary

For 100 guests in Aurora, your single biggest line item is food and bar, which alone will eat 35–45% of your total. The next two pressure points are venue rental (often $4,000–$9,000 in the Fox Valley) and photography ($3,500–$6,500 for full-day coverage). Everything else — flowers, music, attire, stationery, transport — competes for what's left.

Local context

Aurora sits in a sweet spot for cost: it's far enough from downtown Chicago that you avoid Loop pricing, but close enough that you have access to top-tier vendors who travel the I-88 corridor.

What drives cost up in Aurora: - Downtown Aurora venues along the Fox River (Hollywood Casino, Two Brothers Roundhouse, Riverfront properties) command higher rentals than west-side banquet halls. - Saturday evenings May–October are peak; Friday or Sunday weddings can save 15–25% on venue and photography. - Outdoor or tented receptions require rentals (tent, generator, restrooms, climate control) that can add $5,000–$12,000.

What keeps cost down: - Established banquet halls in the Fox Valley (Gaslite Manor, Meson Sabika nearby in Naperville, Q Center in St. Charles area) often bundle venue + catering + bar, which reduces total spend versus à la carte. - Off-peak months (January–March, November) cut venue pricing 10–20%. - Guest count of 100 is the cutoff where many local caterers price more aggressively per head than at 60–75 guests.

Plan around Illinois weather: roughly 60% of Aurora weddings happen May through October. If you're booking in 2025–2026, lock venue and photographer 10–14 months ahead.

FAQ

What's the average wedding cost for 100 guests in Aurora, IL?

The average lands around $42,000, or roughly $420 per guest. Couples who pick an all-inclusive banquet hall and a Friday or Sunday date can come in closer to $32,000, while downtown Aurora and tented outdoor weddings push past $55,000.

How much should I budget for catering for 100 guests near Aurora?

Plan on $10,000–$16,000 for food and another $3,500–$6,500 for bar. Buffet service runs $65–$95 per person, plated dinners $90–$140, and a full open bar adds about $15–$25 per guest over a beer-and-wine package.

Can I do a 100-guest wedding in Aurora for under $25,000?

Yes, but it requires real tradeoffs: a restaurant or community-hall venue, a brunch or appetizer-style menu, beer and wine only, a DJ instead of a band, and digital invitations. Most couples who hit this number choose an off-peak Friday or Sunday and skip videography and florals beyond bouquets.

How far in advance should I book vendors in Aurora?

Book your venue and photographer 10–14 months out for Saturday weddings May through October. Caterers, florists, and DJs typically book 6–9 months ahead. Off-peak dates and weekday weddings give you more flexibility on every vendor.

What's the cheapest month to get married in Aurora, IL?

January, February, and November are the cheapest, with venue discounts of 10–20% and easier vendor availability. December gets pricier again because of holiday parties competing for the same venues.

Do I need to tip vendors, and is that included in the budget?

Tips are not in vendor contracts and should sit in your buffer. Standard amounts: 15–20% on catering and bar staff (often built into contracts as service charge — check), $50–$200 per photographer/videographer/DJ, and $1–$2 per guest for shuttle drivers.

Is the marriage license fee included in these estimates?

The Kane County marriage license costs $30 and is grouped under officiant/license in the table. You apply in person at the County Clerk's office in Geneva, and the license is valid for 60 days.
