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
The baseline for local Saturday spring weddings is 85%. Expect 78–92 of 100 invited guests. Real world numbers can be 3–5 points higher or lower depending on how close your guest list is geographically and how early you send invitations.
Day of week is the biggest lever. Saturday vs. Sunday is an 8 point difference (85% vs. 77%). Saturday vs. weekday is 15 points. Season matters less than day. Spring vs. winter is only 7 points. If you can choose between Sunday and Saturday for the same venue, Saturday is always worth paying for.
Send RSVPs early (8 weeks out), enforce a firm deadline with a follow up at week 4, and use personal links rather than paper mail or email. iDoTogether couples who send text based personal links typically see 80% of RSVPs submitted within the first week, vs. 4–6 weeks chasing paper responses.
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 Local Wedding?
Local weddings have the most predictable attendance math in wedding planning. For a 100 invite local Saturday spring wedding, expect 78–92 guests, with an 85% rate that's the industry's best case baseline. Local attendance can still dip below 80% or spike above 90%, depending on specific demographics and how aggressively you enforce the RSVP deadline. The factors that move local attendance are day of week (Friday is nearly as good as Saturday; Sunday drops 8 points; weekdays drop 15) and season (winter costs 7 points; summer costs 3). Spring and fall are essentially tied for highest attendance.
An 85% attendance rate still means 15 people who don't show, and those {decline} declines won't all confirm early. iDoTogether's RSVP dashboard shows exactly who's pending vs. confirmed so you can stop guessing and start planning with real numbers.
