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 ~35 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 × (65% base) = 65 expected

Frequently Asked Questions
The baseline for destination Saturday spring weddings is 65%. Expect 60–70 out of 100 invited guests to attend. This is roughly 20 percentage points below a local wedding. The range widens when you factor in season and day: a destination winter weekday wedding can see attendance drop to 40–50%.
Send save the dates 9–12 months out for destination weddings, and formal invitations 3–4 months out (vs. 6–8 weeks for local). Your RSVP deadline should still be 4–6 weeks before the wedding to give caterers and venue time to adjust. Guests booking flights need more planning time, but their decision to attend is usually made early.
Yes. Use the 'Fill My Venue' mode on this calculator to find the right over invitation count. For a 65 seat destination venue, you'd need to invite approximately 118 people at a 65% attendance rate. Factor in that some guests will decline purely for financial reasons, not social ones.
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 Destination Wedding?
Destination weddings have a fundamentally different attendance math than local ones. For a 100 invite destination Saturday spring wedding, expect 60–70 guests, with a 65% rate compared to 85% for local. The 35% decline rate isn't a reflection of how much people want to attend. It's a reflection of the real financial and logistical barriers created by flights, hotels, and time off. Budget planning is where this matters most: if you're planning for 100 attendees at a destination and only 65 show up, you've spent too much on venue minimums, catering, and florals. Smart destination couples run both local and destination scenarios before booking the venue.
Destination guests need extra lead time to book flights and hotels, and you need to stop texting everyone individually about dietary restrictions. iDoTogether sends personalized links to each household so guests can RSVP, confirm dietary needs, and submit their address all in one tap.
