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 ~30 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 -15% day) = 70 expected

Frequently Asked Questions
For a local Monday–Thursday spring wedding with 100 invites, expect 64–76 attendees. The midpoint is 70, with 30 declines. Plan catering for 75. Guest lists that skew toward retirees or remote workers typically outperform this baseline.
Wednesday and Thursday consistently outperform Monday and Tuesday. Thursday is often called the 'second Friday.' Guests are already in a near weekend mindset and many take only one day off. Monday weddings have the highest decline rate because of the full week commitment they imply.
It depends on your priorities. A 30% decline rate vs. 15% for Saturday means 30 more declines per 100 invites. If you save $5,000–$15,000 on venue costs, that may be worth inviting a larger list to hit your target headcount. Use the 'Fill My Venue' calculator to find how many invitations you'd need to send to fill your specific venue on a weekday.
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).

Weekday Wedding: Maximum Savings, Clear Attendance Tradeoff
Weekday (Monday–Thursday) weddings carry the largest attendance penalty at 15 points below peak, landing at 70% for local spring weddings. For 100 invites, expect 64–76 attendees. That's 30 declines compared to just 30% for a Saturday spring wedding. The math is stark, but the cost savings are equally stark: weekday venues often run 40–60% below Saturday pricing, and many vendors offer their lowest rates for Tuesday–Thursday bookings. Weekday weddings work best when your guest list is primarily retirees, self employed guests, or people in flexible schedule industries. Guest lists with many 9 to 5 employees, parents with school age children, or guests who need to travel will see higher decline rates than the national average.
Weekday guests need to request PTO, arrange childcare, and potentially book a hotel. Every friction point in your planning process raises the barrier to attendance. iDoTogether's personal RSVP links remove all friction from the guest side so they can respond (and commit) in under 60 seconds.
