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 ~15 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: 100 guests × (85% base) = 85 expected

Frequently Asked Questions
They're statistically identical. Both sit at 85% for local Saturday weddings. The decision usually comes down to weather preference, venue availability, and vendor pricing. Fall often has slightly better foliage for photos in northern states; spring is preferred in southern states.
For a local Saturday fall wedding with 100 invites, expect 78–92 attendees. The midpoint is 85, with a catering buffer of 90.
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).

Saturday Fall Wedding: Tied With Spring for Peak Attendance
Saturday fall weddings match spring exactly. Both sit at an 85% baseline for local weddings. For 100 invites, expect 78–92 attendees. Fall offers one practical advantage over spring: later sunset times mean golden hour photography windows extend through October without the compressed schedule of March weddings. September and October are also the most popular wedding months in the US, which means higher vendor demand but also more options and availability in many markets. The main risk for fall is venue booking lead time. Fall Saturdays at popular venues book 12–18 months out.
Fall Saturdays book fast, and so do caterers, photographers, and florists. While you're locking in vendors, iDoTogether handles the RSVP side: personal links, real time tracking, and automatic reminders so you can focus on vendor contracts instead.
