At 120 invited guests and a 20% decline rate, our estimate is that about 96 people will come. Sort every name into tier A (must invite) or tier B (maybe), pick a decline rate, and read the expected headcount. Then send that one number to your budget and seating chart.
The Knot’s 2025 study put the average guest count at 116 for weddings held in 2024. Your list does not need to match that. It needs to match your budget.
Headcount table for 120 invited guests
Start here. This is what the calculator above computes at its default of 120 invited, shown at three decline rates so you can see the range.
Table: Expected headcount for 120 invited guests at three decline rates (our estimate, assumptions below)
| Decline rate | Guests who decline | Expected headcount | Food and drink at $100 a guest |
|---|---|---|---|
| 10% | 12 | 108 | $10,800 |
| 20% | 24 | 96 | $9,600 |
| 30% | 36 | 84 | $8,400 |
The gap between the best and worst case is 24 people, or $2,400 at our example price.
Assumptions: one decline rate applies to the whole list. The $100 per guest is an example figure we chose, not a market price. Replace it with your caterer’s quote.
Plan the venue around the middle row and check that you can live with the top row. If 108 people would break your room or your budget, trim the list now, not after the invitations go out.
Zola puts guest-dependent costs at roughly $150 to $300 per guest. Our $100 sits below that range, so treat it as a placeholder for the math, not a forecast.
Split the list into A and B
One flat list hides the real question: who must be there? Tiers answer it before anyone argues about a name.
Tier A is the people whose absence would change how the day feels. Immediate family, the wedding party, grandparents, closest friends. Tier A guests also decline least, so their rate is low.
Tier B is everyone you would like to have but could skip. Coworkers, parents’ friends, cousins you see once a year. Tier B declines more.
Table: The same 120 guests with a separate decline rate per tier (our estimate, example rates)
| Tier | Invited | Decline rate | Expected to come |
|---|---|---|---|
| A, must invite | 70 | 10% | 63 |
| B, maybe | 50 | 30% | 35 |
| Total | 120 | 18% overall | 98 |
Splitting by tier gives 98, not 96. The blended rate is 18%, because most of your list sits in the low-decline group. That is a small difference here. It grows when one tier is much larger than the other.
Tiers also give you a plan for sending invitations in two waves. Send tier A first. When replies come in, you know how many B invitations you can afford to send. Check the date your venue needs a final count before you rely on this.
Let each person fill in their own part
The hardest part of a guest list is not the math. It is that three or four people each want to add names.
Give each contributor a share of the list. Here is one example split of the same 120.
Table: One example split of 120 invited guests by who is asking (our estimate, example rates)
| Whose list | Invited | Decline rate | Expected to come |
|---|---|---|---|
| You two | 50 | 10% | 45 |
| Your parents | 30 | 20% | 24 |
| Partner’s parents | 30 | 30% | 21 |
| Parents’ extra friends | 10 | 40% | 6 |
| Total | 120 | 20% overall | 96 |
The two rows at the bottom are where lists grow without anyone deciding. Agree on a number for each contributor before they start, then send the page link so they can add names to their own tier. Our share link keeps what they entered, so the numbers stay in one place.
When a parent asks for more seats, answer with the table: “Your share is 30. You are at 34. Which four come off?”
Steps
- Pick a rough headcount ceiling from your budget. Our budget planner shows what each guest does to the other lines.
- Write down tier A first, with no cap. Count it.
- Give each contributor a number for tier B, so the total fits under your ceiling.
- Set a decline rate. Use 20% if you have no better guess, and check 10% and 30%.
- Read the expected headcount and the three-rate table. Adjust the list, not the math.
- Copy the headcount into your budget and your table plan.
How many to invite to land on a target
Sometimes the room fixes the number. You have space for 100 and want to know how many invitations to send.
Table: Invitations needed to reach 100 guests, rounded up (our estimate)
| Decline rate | Invitations to send | Expected to come |
|---|---|---|
| 10% | 112 | 101 |
| 20% | 125 | 100 |
| 30% | 143 | 100 |
Rule: invitations = target guests divided by (1 minus the decline rate), rounded up.
Be careful at the high end. At 30%, you send 143 invitations to fill 100 seats. If fewer people decline than you assumed, you now have more than the room holds. Use the high row only if you can handle the overflow with a firm RSVP date and a tier B wave you can hold back.
What to put in each column
Whether you build this in a notebook or a spreadsheet, these are the columns that pay for themselves. Copy the list into a sheet header row.
- Name and household. Count people, not envelopes.
- Tier, A or B.
- Side or contributor, so you can see each share.
- Mailing address, collected once, early.
- Plus-one: yes, no or named.
- Kids invited: yes or no, with ages if the venue has a limit.
- RSVP: yes, no or waiting.
- Meal choice and dietary note.
- Table number, filled in last.
Keep the RSVP column honest. A guest who has not replied is “waiting”, not “yes”.
Plus-ones and kids: decide once
These two rules cause more list fights than any single name. Pick a rule before you start, write it at the top of the sheet, and apply it to everyone.
- Plus-one rule, version one: everyone in a relationship gets a plus-one, and nobody else does.
- Plus-one rule, version two: only wedding party members and family get one.
- Kids rule: either every child is invited, or only children in the wedding party and immediate family.
Our decision rule for lists over your ceiling: tighten the plus-one rule first. It removes people you have never met, so it costs you the least.
Cut the list without singling anyone out
When the total is too high, cut a group, not a person. Here is one example order, with what each cut does to a list of 120.
Table: Example cuts from 120 invited, with the expected headcount at a 20% decline rate (our estimate, example cut sizes)
| Cut | People removed | Invited after | Expected to come |
|---|---|---|---|
| Coworkers beyond your own team | 10 | 110 | 88 |
| Plus-ones for guests you have not met | 12 | 98 | 78 |
| Distant relatives with no recent contact | 12 | 86 | 69 |
Three group cuts take the expected headcount from 96 to 69, a drop of 27 people. The cut sizes here are our example, not a norm. Your groups will differ, but the method holds.
Tell people the rule, not a reason about them. “We kept it to family and close friends” is true and ends the conversation. If your budget is the reason, say that. It is a reason nobody argues with.
Smaller guest lists also change which kind of wedding you are planning. See small wedding planning for the micro, backyard and elopement options.
Mistakes that wreck the headcount
Counting envelopes. A household of four is one envelope and four meals. Count heads in the sheet.
Using one decline rate for everyone. Local close friends decline rarely. Out-of-town acquaintances decline often. Tiers fix most of this.
Treating “maybe” as “yes”. Keep a waiting column and use the expected headcount, not the best case.
Adding names after the seating chart. Each late name changes the table math. Lock the list on a date and hold it. When it is locked, move to the seating chart.
Skipping the venue check. Capacity, the catering minimum and the fire-code limit differ. Ask early, and use the venue questions for a tour to cover them.
What to do with the number
The expected headcount is an input for four other decisions.
- Budget. Put it into the 100-guest budget split or the planner itself and read the cost per guest.
- Venue. Compare it with capacity. Leave room for a few late additions.
- Catering. Give the caterer your high-case number as the maximum and your expected number as the guarantee, if they allow it. Ask about their rules.
- Seating. Divide the expected headcount by the seats per table to estimate how many tables you need.
Add your own milestones, such as the date addresses are due and the date the final count is due, to your wedding planning checklist.
Guest list also feeds small details, like how many pages your guest book needs.
Sources and how the numbers are made
The figure of 116 guests and the guest-dependent cost range come from the sources listed at the end of this page. Everything else in the tables is computed by our own arithmetic from the example inputs stated beside each table. The decline rates, tier sizes, cut sizes and the $100 per guest are examples we chose to show the method. They are not survey results.

Questions people ask
How to make a wedding guest list
Start with two columns, not one. Put the people you cannot imagine the day without in tier A. Put everyone else in tier B. Add each person's household, side and a plus-one flag. Count heads, not envelopes. Then set a decline rate and read the expected headcount before you commit to a venue size.
How to cut down a wedding guest list
Cut by rule, not by name. Remove plus-ones for guests you have not met, then adult children's dates you have never met, then coworkers beyond your own team, then distant relatives you have not spoken to in two years. Each rule removes a group, so nobody feels singled out, and you can show the rule to anyone who asks.
How many guests will actually come?
Nobody can promise a number. Declines depend on travel distance, the date, how close each guest is and whether kids are invited. That is why this page asks you to choose a rate. Try 10, 20 and 30 percent, see all three headcounts, and plan the venue and caterer minimum around the middle one with the high one as a check.
How to make a wedding guest list in Google Sheets
Make one row per person with columns for name, household, tier, side, RSVP, meal, dietary note, plus-one and table. Add a dropdown for tier and RSVP. Count tier A with COUNTIF on the tier column. Share the sheet with your parents as comment-only, or have each of them fill in their own tab, then merge the tabs.
Should the guest list come before the venue?
Yes, at least a rough one. Venue capacity, the catering minimum and the seating layout all depend on headcount. A list of 120 invited with a 20 percent decline rate is a better planning input than a guess of about 100. You can refine the list later without redoing the search for a room.
