Guest List & Seating Calculator

Wedding guest list management requires tracking guests by category, counting totals, estimating RSVPs, and mapping guest count to venue capacity and per-head cost. A structured formula approach prevents budget surprises and seating chaos.

The master count formula: Total Invited = Bride’s Family + Groom’s Family + Couple’s Friends + Work Colleagues + Other Expected Attendance = Total Invited × RSVP Rate

Typical RSVP (acceptance) rates:

• Local guests (within 1 hour): 85–95% will attend
• Out-of-town guests (2+ hours away): 55–75% will attend
• Destination wedding guests: 35–55% will attend
• Overall blended average: 75–80% for a typical wedding

Worked example: Guest list: 180 invited (120 local, 60 out-of-town) Expected attendance:

• Local: 120 × 0.90 = 108
• Out-of-town: 60 × 0.65 = 39
• Expected headcount: 147 guests

Budget per-head calculation: Food and Beverage Cost = Expected Guests × Per-Head Catering Rate Total Reception Cost = Venue Fee + Food + Bar + Cake + Floral + Staff

If catering is $95/person: 147 × $95 = $13,965

Category breakdown (recommended):

• Immediate family (both sides): 20–40 people
• Extended family: 30–60 people
• Close friends: 20–40 people
• Work colleagues: 10–20 people
• Plus-ones for guests: budget 50–70% of singles will bring one

Venue capacity rule: book for 10-15% more than your expected headcount, to absorb late acceptances and to leave the room comfortable. This calculator uses 12%. Never book to the venue’s stated maximum: that figure assumes wall-to-wall seating with no dance floor, no band, no bar and no cake table, and a room at its official capacity feels packed rather than full.

Seating math: typical round tables seat 8 to 10. At 8 per table, 147 guests need 19 tables; at 10 per table, 15. The calculator shows all four common sizes so you can see what the choice costs you in centerpieces, because every table you add is another centerpiece, another linen and another table number.
