TL;DR: A 100-guest wedding in Simi Valley typically costs $42,000 – $72,000, with most couples landing near $55,000. Venue and catering alone usually consume 55–60% of the budget, driven by Ventura County labor rates and LA-adjacent vendor pricing.
Useful summary
Simi Valley sits in a pricing pocket that's cheaper than central LA but pricier than inland California. For 100 guests, expect a per-guest all-in cost of roughly $420 – $720, depending on venue type, bar service, and how much you DIY.
Your budget will swing most based on three decisions:
- Venue type — a ranch or backyard estate runs very differently than the Reagan Library or a Westlake Village resort.
- Bar package — full open bar adds $40–$70 per guest versus beer/wine only.
- Saturday vs. Friday/Sunday — off-peak days can save 15–25% on venue and vendor fees.
A realistic working number for a mid-range Simi Valley wedding with 100 guests is $50,000 – $58,000 before rings and honeymoon.

Local context
Simi Valley pulls vendors from both Ventura County and the San Fernando Valley, which gives you more choice but also more price variance. A few things to plan around:
- Venues to know. The Ronald Reagan Presidential Library, Hummingbird Nest Ranch, Lost Canyons, Bella Vista Ranch & Event Center, and Sycamore Hills anchor the local scene. Site fees commonly run $6,000 – $14,000 for a Saturday.
- Climate. Summer afternoons regularly hit 90–100°F. Outdoor ceremonies before 5 PM in July/August need shade, fans, or a tent — budget $1,500 – $3,500 for guest comfort rentals.
- Wind. Simi and the surrounding canyons get strong evening gusts. Lightweight floral installations and tall centerpieces need anchoring; expect a small upcharge.
- Fire season. September and October bookings carry real risk. Trip insurance and a venue with a clear cancellation policy matter more here than in most markets.
- Travel. Many couples pull guests from LA and the Conejo Valley. Hotel blocks at the Grand Vista or properties in Thousand Oaks typically run $160 – $230/night.
- Sales tax & service. Catering quotes in Ventura County usually exclude 7.25% sales tax and a 20–22% service charge — confirm whether your quote is gross or net before comparing.

FAQ
What's the minimum realistic budget for 100 guests in Simi Valley?
Around $32,000 – $38,000, but only if you pick a low-fee venue (a private ranch or community space), use a casual caterer, do beer/wine only, and skip videography. Below that, you're cutting categories most couples regret cutting.
How much should I budget for catering alone?
Plan on $130 – $200 per guest for a plated or buffet dinner with staff and rentals included. Family-style and stations land in the same range. That puts catering at $13,000 – $20,000 for 100 guests, before bar.
Is the Reagan Library worth the cost?
The Reagan Library site fee typically runs $15,000 – $25,000 depending on space and date, plus required vendors. It's worth it if the iconic setting is central to your vision — but it pushes your total budget toward $75,000+ for 100 guests.
How much does a Friday or Sunday save?
Expect 15–25% off venue site fees and 5–10% off most vendors for Friday or Sunday in Simi Valley. On a $55,000 Saturday budget, that's roughly $5,000 – $9,000 in savings.
What's typically forgotten in a 100-guest budget?
Most couples underbudget service charges and tax (often 25–30% added to catering), vendor meals (~$40 each, for 8–12 vendors), tips ($1,500 – $3,000 total), and day-of transportation for the wedding party. Build in a 10% buffer.
Do I need a wedding coordinator at this size?
Yes — at 100 guests with multiple vendors and a venue that often requires outside catering, a month-of coordinator ($1,800 – $3,500) is the highest-ROI line item in your budget. Full planning runs $5,000 – $9,000 locally.
How far in advance do Simi Valley venues book?
Popular venues book 9–14 months out for Saturdays in peak season (May, June, September, October). Off-peak Saturdays and Friday/Sunday dates can sometimes be booked 4–6 months out.
