Wedding RSVP Drop-off Calculator
Stop guessing who is actually coming. Calculate your exact RSVP drop-off rate so you don't overbook your venue or waste thousands on empty plates.
Your Estimate
You are about to have ~26 empty seats. Do you know whose they are?
If you give your caterer a guess, you pay for those plates anyway. iDoTogether sends one personal link to your guests' phones. You get hard, confirmed RSVPs instantly so you only pay for people who actually show up.
Formula: 175 guests × (85% base) = 149 expected

Frequently Asked Questions
For a local Saturday spring wedding, expect 137–161 out of 175. The midpoint is 149. Plan catering for 158. Destination weddings at 175 invites drop to roughly 113 attendees.
Set a firm cutoff. Anyone who doesn't respond by 3 weeks out is marked as not attending. Build a small "courtesy overflow" table for 3–5 unexpected late additions. iDoTogether timestamps every RSVP submission so you can enforce the cutoff cleanly.
On average, 15-20% of invited guests decline a local wedding. For destination weddings, the decline rate jumps to 30-40%. Factors like day of the week, season, and travel distance all affect the final number. Saturday weddings see the highest attendance, while weekday ceremonies can see decline rates as high as 30%.
The average wedding drop-off rate is about 15% for local weddings held on a Saturday. This means if you invite 100 guests, roughly 128 will attend. Destination weddings have a much higher drop-off rate of around 35%, meaning only 98 out of 100 would attend. These are industry averages — your actual numbers will depend on your specific guest demographics.
It depends on your wedding type. For a local Saturday wedding, you can safely invite 15-20% more guests than your venue capacity. For a destination wedding, you may be able to invite 50-55% more. Use the 'Fill My Venue' mode above to find the right invite count for your venue size.
Season plays a meaningful role. Spring and fall weddings tend to see the highest turnout due to comfortable weather and fewer travel conflicts. Summer weddings (especially July/August) can see 3-5% lower attendance due to vacation conflicts. Winter weddings often see 5-8% lower attendance due to weather and holiday scheduling.
Friday weddings perform much closer to Saturday than Sunday does. Many guests are already in a weekend mindset, and taking one day off from work is more manageable than losing a Sunday evening before the work week. Sunday weddings consistently show higher decline rates because guests need to be back at work Monday morning.
The biggest bottleneck is chasing people who ignore paper mail. iDoTogether lets you text each guest a personal link. They tap it, RSVP, and submit their meal choice in under 60 seconds. Couples using our software typically collect 80% of RSVPs within the first week.
Send RSVP requests 6-8 weeks before your wedding date. Follow up with non-responders at the 4-week mark. (Pro-tip: If you use iDoTogether, your dashboard automatically flags exactly who hasn't answered, so you don't have to manually cross-reference a spreadsheet).

Planning a 175 Person Wedding?
175 guests requires the same level of structure as a corporate event. For a local Saturday spring wedding, you'll have 149 expected attendees and 26 declines, but the real challenge is that those 26 declines won't all be confirmed by the time you need to give your caterer a headcount. Build in an RSVP deadline 4 weeks before the wedding and a hard cutoff at 3 weeks. Waitlist management also becomes relevant: if you're planning assigned seating, having 5–10 late additions creates a ripple effect across table assignments.
At 175 guests, you'll have 20+ people who have not responded by your deadline and at least one partner spending evenings chasing people down. iDoTogether distributes that workload automatically, and both partners get dashboard access while guests respond via personal link.
