The short answer
One more wedding guest costs the sum of each line priced per person in your contracts, plus the service charge and tax calculated on those lines, so the cost per guest is more than the menu price. A smaller count can save less than you expect if it drops below a guest or spending minimum. Work it out from the rates, bases and minimums in your own contracts.
Which wedding costs change with the guest count?
Go through each contract and mark the lines that are priced per person or per unit that follows the count: the meal, a bar package, dessert or cake by the slice, a cake cutting fee, chairs and place settings, favors, printed menus, and seats on a shuttle. These move one guest at a time.
Then mark lines that move in steps. Tables, linens and centerpieces may change only when the count crosses a table size. A contract may tie staffing to the count, such as a server or bartender for a set number of guests. Finally, mark the fixed lines, such as a venue rental fee or a photographer package, which do not move with the count at all.

How do I calculate the cost per guest for a wedding?
Add up the per-person prices from your catering or venue contract, then apply the percentages in the order and on the bases the contract states. If a service charge applies to food and beverage, and sales tax applies to food, beverage and service charge together, the per-guest figure is the per-person total, times one plus the service rate, times one plus the tax rate.
For example, take a hypothetical contract with dinner at $78, a bar package at $32 and dessert at $4, or $114 a person. A 22% service charge adds $25.08, making $139.08, and 8% tax on that adds $11.13. One guest costs $150.21 from this contract, not $114. Check your own contract for the bases, because tax may not apply to a service charge in your state.
How much do ten more wedding guests cost? For example
Continue the hypothetical. Ten more guests add $1,140 of per-person charges, a $250.80 service charge and $111.26 of tax on $1,390.80, for $1,502.06 from the caterer. Suppose the rental company charges $6 a guest for a chair and place setting, plus 8% tax, which adds $64.80 for ten guests.
If tables seat ten and the count moves from 110 to 120, you also need a twelfth table. With a hypothetical $125 for its linen and centerpiece, the ten guests together cost $1,502.06 + $64.80 + $125 = $1,691.86, or about $169 each. Run the same arithmetic with your own rates before you add names to the list.
Does cutting the wedding guest count save money?
Cutting the wedding guest count saves money on each per-person line until the count reaches a minimum in the contract, so look for two kinds of minimum. A guest minimum says you will be billed for at least a set number of guests. A food and beverage minimum says you will spend at least a set amount before service charge and tax, or with them, depending on the wording. Cutting below either one stops saving money on the lines it covers.
For example, with a hypothetical 100-guest minimum and the $150.21 figure above, reducing from 110 to 95 guests saves the charge for 10 guests, $1,502.06, not 15. If the contract also had a $12,000 food and beverage minimum, 100 guests at $114 is $11,400, leaving a $600 shortfall. Ask how the shortfall is billed and whether service charge and tax apply to it.
Until when can the guest count change?
Your contract sets this, not a general rule. Find the final count clause and note the date or the number of days before the event, whether the final count is a guarantee you will be billed for even if fewer attend, and whether increases are accepted after that date and on what terms. Rental and transport contracts may have their own deadlines for quantities.
Put each deadline on your calendar and work back from the earliest one to set your RSVP date, so you have real replies before you commit. If a deadline has passed and your count changes, ask the vendor in writing whether they can adjust, and at what price.
How do I compare guest count scenarios before deciding?
Build a small table with your current count and two or three alternatives, such as ten more and ten fewer. For each, total the per-guest lines with their percentages, the step lines at the right number of tables, the fixed lines, and any minimum shortfall. The difference between columns is the real cost or saving of that change.
Share the table with anyone contributing to the budget before the list changes. Seeing that a hypothetical ten guests cost about $1,700, not $1,140, can change the conversation, and it gives your contingency line a figure to hold if the count is still uncertain.

A message you can make your own
Change the wording to suit you, fill in anything in brackets and keep the questions that apply. You decide what to send and send it yourself.
We are finalizing our guest list for [date] and want to understand the cost of a change before we decide. Could you confirm, in writing, the per-person price for each item on our contract, which of them the service charge and tax apply to, and whether any staffing or equipment changes at particular counts? Please also confirm our guest or spending minimum, how a shortfall would be billed, and the last date on which we can change the count up or down.
Common questions
What is the average cost per wedding guest?
The average cost per wedding guest is not a figure you can rely on for your own date, because it depends on the menu, the bar, the service charge and tax bases, the rentals and any minimum in your contracts. Build your own cost per guest from the per-person lines each vendor quotes in writing, and compare quotes on that same basis.
How do you calculate guest count for catering?
The guest count for catering is the number of people the caterer prepares for and bills, split the way the contract prices them. List adults, children in each age band and vendor meals separately, check which of them count toward any minimum, and give the caterer that split in writing by the final count date the contract states.
Does reducing the guest count lower the service charge?
Reducing the guest count lowers the service charge when the charge is a percentage of per-person lines that fall with the count, unless a minimum applies. Check whether the service charge is calculated on actual spend or on the minimum, and whether it is also added to any shortfall between the two.
Is it cheaper to cut wedding guests or change the menu?
Cutting wedding guests or changing the menu can each lower the total, and your contract rates show which saves more. Price both in the worksheet: for example, in the hypothetical above, ten fewer guests remove $1,502.06 from the caterer, while a hypothetical $10 cheaper entree for 110 guests removes $1,100 before service charge and tax. Check any minimum against both totals.
Do children count toward the wedding guest count cost?
Children count toward the wedding guest count cost in the way each contract states. A contract may offer a separate price for children, count them differently toward a minimum, or bill them as adults. Check each per-person line, and ask the vendor in writing how children are priced and counted if the contract does not say.
Do vendor meals add to the cost per guest?
Vendor meals add to the catering total but belong on their own line rather than in the cost per guest. A catering contract may price them separately from guest meals, and they may or may not count toward a minimum. List them apart from guests, with the price and service charge the contract states, so they are neither missed nor counted twice.
