A 100-guest wedding in Washington typically runs $42,000 – $72,000 all-in, with most couples landing near $54,000. That works out to roughly $420 – $720 per guest, driven mostly by venue, catering, and photography — the three line items where Washington pricing sits 15–25% above the national average.
Useful summary
You're planning for 100 guests in a state where vendor demand is high, peak season is short, and venue minimums do most of the damage. Here's what to know before you start allocating dollars:
- Total range: $42,000 – $72,000 for a full-service wedding.
- Median: ~$54,000 (Seattle metro pulls this up; eastern Washington pulls it down by 20–30%).
- Per-guest cost: $420 – $720, depending on venue type and bar package.
- Biggest variable: venue + catering combined, which typically eats 50–55% of the total.
- Peak season premium: July through September weddings cost 15–20% more than May, October, or off-season dates.
If you're trying to come in under $40,000 with 100 guests, you'll need to shift to a Friday/Sunday date, an off-season month, or a non-traditional venue (park, family property, restaurant buyout).

Local context
Washington isn't one wedding market — it's at least three, and pricing varies sharply.
- Seattle / Eastside (Bellevue, Kirkland, Woodinville): the most expensive zone. Venue minimums at hotel ballrooms and Woodinville wineries routinely start at $12,000 – $18,000 for a Saturday in summer. Sodo and Georgetown industrial venues can land closer to $7,000 – $10,000 if you're flexible.
- Tacoma, Olympia, and the Kitsap Peninsula: 15–20% cheaper than Seattle for comparable venues. Strong inventory of waterfront and historic spaces.
- Eastern Washington (Walla Walla, Spokane, Yakima Valley): vineyard and ranch venues at $4,000 – $8,000 site fees. Catering and floral costs run 25–30% lower than Seattle.
Climate matters more than couples expect. Washington's "guaranteed dry" window is roughly mid-July to early September. Outdoor ceremonies in May, June, or October require a real rain plan — usually a tent ($1,500 – $4,500 for 100 guests with sides) or a venue with a covered backup space. Don't skip this; budgeting for it after the fact is where surprise costs show up.
Vendor sales tax in Washington applies to most wedding services and rentals (8.8 – 10.4% depending on county), and gratuities aren't always built into catering quotes. Always ask whether a quote is "all-in" or pre-tax/pre-service.
Marriage license: $62 – $74 depending on county, with a 3-day waiting period after issuance.

To pressure-test these numbers against your specific situation, work through the Wedding Budget Calculator — it accounts for guest count, region, and priorities. Pair it with the Wedding Budget Guide for category-by-category benchmarks, and the Wedding Checklist Guide so spending lines up with the right planning month.
If you're still narrowing guest count, compare costs at smaller scales: 25-guest budget, 50-guest budget, and 75-guest budget. Cutting from 100 to 75 typically saves $8,000 – $12,000; cutting to 50 saves $18,000 – $25,000.

The fastest way to get a Washington-specific number is to plug your priorities into the calculator and let it allocate. You'll get a category-by-category budget, see where you're over or under local benchmarks, and can lock in spending caps before you start booking vendors.
FAQ
Is $50,000 enough for a 100-person wedding in Washington?
Yes, in most of the state. $50,000 lands you a solid mid-tier wedding with a real venue, full catering, professional photography, and DJ — especially in Tacoma, Spokane, or off-peak Seattle. In peak-season Seattle or Woodinville with a Saturday date, $50,000 is tight and you'll need to compromise on either bar package, florals, or videography.
What's the cheapest month to get married in Washington?
January and February are the cheapest, with venue discounts of 25–40% off peak rates. November, early December (before holidays), and March are the next-best value. The tradeoff is weather — expect rain and limit outdoor plans to covered spaces.
How much should I budget for the bar at 100 guests in Washington?
Plan on $3,000 – $7,500. Beer and wine only runs $25 – $45 per guest; full bar with signature cocktails runs $50 – $80 per guest. Washington allows licensed caterers and venues to handle alcohol service, but BYOB venues (where you supply liquor and pay a corkage/service fee) can cut bar costs by 30–50%.
Do I need a wedding planner for a 100-guest Washington wedding?
You need at least a month-of coordinator, which runs $1,500 – $3,000 in Washington. Most venues require one. Full-service planning ($6,000 – $12,000) is worth it if you're working across multiple vendors, planning from out of state, or doing an outdoor or non-traditional venue where logistics get complex.
How much does catering cost per person in Washington?
Expect $90 – $180 per person for food alone, before bar, tax, and gratuity. Buffet and family-style sit at the low end ($90 – $120), plated dinners run $120 – $160, and stations or premium plated land at $150 – $180+. Add 18–22% service charge and 8.8 – 10.4% sales tax to get the real number.
What does a 100-guest Seattle wedding cost compared to one in Spokane?
Seattle typically costs $58,000 – $72,000 for a comparable 100-guest wedding; Spokane runs $38,000 – $52,000. The gap comes from venue site fees (often double in Seattle), catering minimums, and floral pricing. Photography and DJ rates are closer to even across the state.
How much should I keep as a buffer?
Hold back 10–12% of your total budget — $4,500 to $8,500 at this guest count — for tax, tips, vendor overtime, last-minute additions, and the small items (welcome bags, marriage license, alterations, day-of emergencies) that nobody plans for but everybody spends on.
