The final headcount for your wedding, worked out step by step
The final headcount is the one number your caterer bills you on, and it is due before every reply is in. Here is when it is due, how to get from a list of replies to a number you can sign, and what to do with the guests who never answered.

The short answer
Most caterers want the final headcount between five working days and two weeks before the wedding, and your contract sets the exact date. Count everyone who said yes, add the guests you are certain of, add the two of you if you are not on your own list, and give vendor and children's meals as separate numbers. Many contracts bill the guaranteed count or the number served, whichever is greater, so do not pad it.
The final headcount, sometimes called the guarantee, is the number of meals you promise to pay for. After it is in, the caterer orders food and books staff against it. A higher number later may still be possible, at a cost. A lower one usually is not.
The hard part is not the date. It is that the date arrives while a few replies are still missing, a few guests have changed their minds, and the number on your guest list is not quite the number of plates. This guide works one wedding through from the RSVP date to the message you send the caterer.
When the final headcount is due
The date is in your catering or venue contract, and it varies. Four caterers that publish theirs:
| Caterer | Final count due |
|---|---|
| Park Ave Catering | 14 days before, with entrées, dietary needs, vendor meals and children's meals |
| University of Iowa Catering | 8 business days before a wedding |
| BYU Catering | 5 business days before |
| Kahn's Catering | 5 working days before |
So the usual window is one to two weeks before the wedding. Some caterers also want the layout and the number of guests per table a few days after the count: Park Ave asks for the floor plan and rental order 10 days before. Look for both dates when you sign, and write them down with the payment dates.
If you do not know your date yet, plan for two weeks before. That is what our free checklist assumes, and an earlier date in your contract always wins.
Work back from it to the RSVP date
The headcount date sets everything before it. Take away about ten days for chasing missing replies and you have the RSVP date to print on the invitation. Our guide to when to send wedding invitations walks through the whole chain.
The example in this guide: a wedding on Saturday 12 June 2027, with the final count due 14 days before, on Saturday 29 May. Ten days earlier, the RSVP date is Wednesday 19 May. With six weeks for guests to reply, the invitations go out on Wednesday 7 April.

The couple invited 140 people, plus-ones included. Here is how the number moves.
1. On the RSVP date, count what you have. On 19 May: 104 yes, 22 no and 14 with no reply.
2. Follow up, by name. A short personal message to each of the 14, with a date: "We send our final numbers on Saturday, can you let us know by Thursday?" By 27 May, nine have answered: six yes and three no. That makes 110 yes, 25 no and 5 silent.
3. Decide about the silent ones, one at a time. This is the decision rule:
- Count them as a yes only if you are sure they will come. Two of the five are an aunt and uncle who told a parent they are booked on a flight. They go in.
- Count everyone else as a no, and tell them. The other three get a kind message saying you have had to send final numbers without them, and that you hope to see them soon. A guest who never answered is not a yes until they say so.
Now the count is 112.
4. Add the people the guest list forgets. Most couples are not on their own guest list. Add the two of you: 114 guests.
5. Split out children's meals. Six of the 114 are children on the children's menu, so the caterer needs 108 adult meals and 6 children's meals.
6. Add vendor meals as their own line. The photographers (two), the DJ and the planner will be there through dinner. Ask each contract whether a meal is owed. Here that is 4 vendor meals, often at a different price.
7. List the dietary needs by name. Seven vegetarian, two gluten-free and one nut allergy, each with the guest's name and table, so the servers know which plate goes where.
The message to the caterer:
Our final numbers for 12 June: 114 guests, of whom 108 adults and 6 children on the children's menu, plus 4 vendor meals. Dietary needs: 7 vegetarian, 2 gluten-free, 1 nut allergy, listed by name and table in the attached guest list.
Why you should not pad the number
It is tempting to add five "just in case". Read the billing line first. BYU Catering's policy is typical of how these contracts work: it bills the final guaranteed count or the number of guests served, whichever is greater, and it only makes enough food for the guaranteed number. Kahn's Catering treats the count as the guaranteed minimum. So:
- Every head you guarantee is paid for, whether anyone sits in front of the plate or not.
- A guest who drops out after the deadline is still paid for. On a list of a hundred or more, expect the odd one.
- A late yes may still be possible. BYU says changes inside five business days carry extra charges, if they can be accommodated, and Iowa's general policy charges $25 for late additions. Ask your caterer what theirs is before you need it.
The rule: guarantee the people you have counted, and know the price of a late addition. That costs less than paying for empty chairs.
Yes, I Do
Every guest, every reply
Paste a list from anywhere and it becomes names. Replies, plus-ones, dietary notes and tables stay in one place, for both of you.

Who sends the number
One of you should own the final headcount: the person who has been marking replies, or the one who signed the catering contract. The other takes the follow-up messages to their own side of the list, since a nudge from someone a guest knows works better. Our guide to planning a wedding together has a way to split the rest of the work.
Once the number is in, the same list becomes the seating plan. Our seating chart guide starts from exactly this point, and the vendor payment guide explains why the caterer's final invoice often follows the headcount.
The headcount in Yes, I Do
In Yes, I Do, each guest is marked yes, no or pending, with their plus-ones and dietary notes on the same row. Both of you can mark replies from your own phones as they come in. In the last six weeks, the home screen can remind you how many guests have not replied, so you follow up before you confirm numbers with your caterer.
When it is time to send the count, the guest packet gathers it in one place: how many seats are coming, how many are pending or declined, the plus-ones, the split by side, every dietary note grouped with the names that go with it, and each guest's table. Choose attending guests only or everyone, and share it as a PDF or a CSV. Vendor meals and children's meals are not on it, so add those lines yourself.

Questions
When do you give the final headcount for a wedding?
When your contract says, usually between five working days and two weeks before the wedding. Park Ave Catering asks for it 14 days before, the University of Iowa 8 business days before, and BYU and Kahn's 5. If you have no date yet, plan for two weeks.
Do you pay for guests who do not show up?
Usually, yes. Many catering contracts bill the guaranteed count or the number served, whichever is greater, so a guest who drops out after the deadline is still paid for. That is why the count should hold only the guests you are sure of.
Should you include vendors in the final headcount?
Give vendor meals as a separate number. Your photographer, DJ or planner may be owed a meal by their contract, and caterers often price vendor meals differently. Park Ave Catering asks for vendor meal counts alongside the guest count.
Do the couple count in the headcount?
Yes. You eat too, and most couples are not on their own guest list, so add two. Check the wedding party as well if they sit at a head table that is not on the list.
What if guests RSVP after the final headcount?
Ask your caterer straight away. Some can add a guest for an extra charge, and others cannot promise the same menu. BYU, for example, charges for changes inside five business days and only if it can accommodate them.
Can you lower the final headcount?
Usually not once the deadline has passed, because the food and staff are ordered against it. Before the deadline, change it as often as you need.
