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 ~22 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 -7% season) = 78 expected

Frequently Asked Questions
Winter costs 22% more declines than spring. Expect 78 attendees instead of roughly 85 from 100 invites. In northern states with heavy snowfall, the variance is wider. Southern states (Texas, Florida, Arizona) see almost no winter penalty and sometimes prefer cooler weather for outdoor elements.
Often yes. Venues and caterers are 20–35% cheaper in January and February than in peak months. The 22% attendance penalty means roughly 22 fewer guests for 100 invites. If you're budget constrained, the cost savings often outweigh the attendance difference, especially if your guest list is heavily local.
Early November and mid January are the least conflicted winter months. Late November (Thanksgiving), the two weeks before Christmas, and New Year's weekend carry the highest conflict rates. If you must have a winter wedding, avoid those windows.
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 Winter Wedding: Budget Friendly, Attendance Penalty
Winter weddings carry a 7 point attendance penalty compared to spring and fall, landing at 78% for local Saturday weddings. For 100 invites, expect 72–84 attendees, about 7 fewer people than the same wedding in spring. The penalty comes from three sources: weather uncertainty (particularly in northern states), holiday scheduling conflicts (November–early December has heavy travel competition; late December/January has competing family obligations), and the general perception that winter travel is higher risk. The upside: winter is off peak for vendors, which means significantly lower venue and catering costs, often 20–35% below peak season pricing. For budget conscious couples, the 7 point attendance tradeoff is usually worth the savings.
Winter guests are weighing weather risk and holiday conflicts when they RSVP. Make it as easy as possible for them to say yes. iDoTogether's personal links work on any device, take under 60 seconds, and don't require creating an account.
