TL;DR: A 100-guest wedding in Westminster, CO typically runs $34,000 – $58,000 all-in, with a realistic midpoint around $44,000. Expect venue and catering to eat roughly 55% of that, and plan for Denver-metro vendor pricing with a slight discount versus downtown Denver.
Useful summary
Westminster sits between Denver and Boulder, which gives you access to vendors from both markets without paying full downtown Denver rates. For 100 guests, most couples land in one of three bands:
- Lean budget ($34,000 – $40,000): Public or community venue, buffet catering, 8-hour photography, DJ, supermarket-florist mix, limited bar.
- Mid-range ($40,000 – $50,000): Dedicated wedding venue or hotel ballroom, plated or stations catering, full photo/video, DJ or small band, beer-wine-signature bar.
- Elevated ($50,000 – $58,000+): Standing Bears Shelter, The Bradford, or a Boulder-adjacent estate; full florals, premium photo + video, live band, open bar, day-of coordinator.
The biggest line-item swings in this market are bar package ($2,500–$9,000 for 100 guests), florals ($3,000–$10,000), and whether you bring in a planner ($2,500–$6,500 for partial to full service).

Local context
A few things that actually move the number in Westminster:
- Venue mix. Popular options include The Bradford (historic estate in north Westminster), Ranch Country Club, Standing Bears Shelter at Westminster Hills Open Space, and hotel ballrooms along the US-36 corridor. Standley Lake and Legacy Ridge also host outdoor ceremonies with permits.
- Season matters more than day of week. June–September books 12–18 months out and commands 15–25% premiums. November, January, and February regularly discount venue fees 20–30%, and Friday/Sunday saves another 10–15%.
- Altitude and weather planning. At ~5,400 ft elevation, afternoon summer thunderstorms are real — any outdoor ceremony needs a written rain plan, which usually means a tent rental ($1,200–$3,500) or an indoor backup room you've actually reserved.
- Vendor travel. Most Denver and Boulder vendors don't charge travel fees to Westminster, so you have the full metro pool to shop from without a surcharge.
- Tax and service. Colorado sales tax plus Westminster local tax runs around 8.6%, and caterers typically add 18–22% service. Budget these on top of menu prices, not inside them.

FAQ
Is $40,000 enough for a 100-guest wedding in Westminster?
Yes, $40,000 is workable for 100 guests if you choose an off-peak date, a venue under $6,500, and a beer-and-wine bar instead of full open. Expect to make tradeoffs on videography, live music, or high-end florals — not all three, but probably one.
How much should we budget per guest in Westminster, CO?
Food and beverage alone run $110–$180 per guest in the Denver metro, including service and tax. All-in, across every category, a midrange Westminster wedding works out to roughly $400–$500 per guest at 100 people.
What's the cheapest legitimate venue option near Westminster?
Westminster Hills Open Space shelters, Big Dry Creek venues, and community centers in Broomfield and Thornton rent for $800–$2,500, but you bring in everything — catering, rentals, bar, restrooms if it's outdoor. Factor $4,000–$7,000 in rentals before deciding it's actually cheaper than a turnkey venue.
Do we need a day-of coordinator?
If your venue doesn't include one, yes. A day-of or month-of coordinator runs $1,500–$2,800 in this market and almost always pays for itself in vendor coordination, timeline management, and preventing family members from working your wedding.
How far ahead should we book vendors in Westminster?
Book venue and photographer 10–14 months out for summer dates; catering and DJ 8–10 months; florals and hair/makeup 5–7 months. Saturday dates between May and October routinely sell out a year in advance at the popular venues.
Should we tip vendors, and is that in the budget?
Tipping is customary for service-based vendors (catering staff, hair/makeup, transportation, musicians). Budget 3–5% of your total for tips and thank-you gifts — on a $44,000 wedding that's roughly $1,500–$2,200, and it's easy to forget until the week of.
How much should we keep in a contingency fund?
Hold back 5–8% of your total budget for overruns — final guest count, extra rental hours, last-minute alterations, welcome bags, day-of tips. For a $44,000 Westminster wedding, that's $2,200–$3,500 you don't touch until month one.
