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 ~18 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 -3% season) = 82 expected

Frequently Asked Questions
For a local summer wedding, expect 18% declines, about 18 people out of 100. This is slightly higher than spring due to vacation conflicts, especially in July and August. June weddings often perform closer to the spring baseline.
Fall and spring are tied at the 85% baseline for Saturday weddings. Summer is lower by 3 points (82%). If you have flexibility, fall or spring gives you slightly higher attendance and more predictable weather in most regions.
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 Summer Wedding: Almost as Good as Spring
Saturday summer weddings are popular and nearly as well attended as spring, just 3 percentage points lower (82% vs. 85%). For 100 invites, expect 75–89 attendees. The summer attendance penalty comes primarily from July–August vacation conflicts and destination travel that competes for the same weekends. June weddings typically perform closer to the spring baseline. If your guest list includes many families with young children, summer school schedule flexibility can actually help attendance. The main tradeoff is vendor pricing: summer is peak season, so venues and caterers are more expensive.
Summer guests are harder to pin down because they're juggling vacation plans. iDoTogether's personal links let guests RSVP in one tap with no email, no form, and no login, so you get responses faster even from distracted summer mode guests.
