The Catering Quote Hiding $40 a Plate
The first time you ask a caterer for a price, you get one number. It looks clean. It fits on a spreadsheet line. Then the contract arrives, and that number has grown three new neighbors.
Here's the short answer: a wedding catering quote of "$110++" is almost never $110 per guest. The two plus signs stand for service charge and tax. Once you stack on gratuity, you're usually paying 25 to 35 percent more than the quoted number. On 150 guests, that's the difference between $16,500 and $22,600 — and it shows up after you've already signed.
What does "plus-plus" pricing actually mean?
"Plus-plus" is the catering industry's shorthand for a base per-guest price that hasn't been finalized yet. A quote of $110++ means $110 plus service charge plus tax. The dollar sign is doing the obvious work. The two plus signs are doing the quiet, expensive work.
The first plus is usually a service charge of 20 to 25 percent of the food and beverage subtotal. The second plus is sales tax, which depends on your state but often lands between 6 and 10 percent. And in many contracts, there is a third line that doesn't get a plus sign at all: gratuity, sitting on top of both.
This is where most people get stuck. They build a budget around the per-guest price they were quoted. The contract numbers come in. Suddenly the catering line is thousands of dollars higher than the spreadsheet said it would be, and nothing has actually changed except the math finally being complete.
Is the service charge the same as the tip?
No. This trips up couples more than any other line on a catering invoice. A service charge of 20 to 25 percent is paid to the venue or the catering company to cover administrative costs, coordination, and overhead. It does not go to the staff who serve your meal.
Gratuity is a separate line item that goes to the servers, bartenders, and kitchen team. Most contracts treat it as 15 to 20 percent of the same subtotal. Some venues bundle it into the service charge. Others list it separately. A handful expect you to add it yourself.
If you assume the service charge covers the tip, you'll either underbudget by 15 to 20 percent or feel ambushed at the end of the night. The fix is to ask one direct question before you sign: "Is gratuity included in the service charge, or is it billed separately?" Get the answer in writing.
How much does a $110-per-plate wedding actually cost?
Here is the math, line by line, for 150 guests at $110 per plate:
- Food and beverage subtotal: $16,500
- Service charge at 22 percent: $3,630
- Gratuity at 18 percent: $2,970
- Tax at 8 percent (on the full subtotal including service): $1,610
- Final catering total: roughly $24,710
That's the all-in number. Notice that the tax is often calculated on the subtotal plus the service charge, which is a small detail that quietly adds a few hundred dollars on its own. Notice also that none of this includes rentals, cake-cutting fees, corkage, overtime, or any vendor meal requirements. Those are separate lines.
The gap between "$110 a plate" and "$24,710 catering total" is not a scam. It's standard. It's how the industry quotes. But if your spreadsheet only has the $16,500 line, you're going to spend the last six weeks before the wedding rearranging other categories to absorb the surprise.
What questions should I ask before signing a catering contract?
Five questions, in this order. Answers in writing.
- What is the all-in per-guest price? Force the caterer to add service charge, gratuity, and tax to the quoted figure and give you one number. If they're reluctant, that's a signal.
- What is the service charge percentage, and does it include gratuity? If it doesn't, ask the next question.
- What is the expected gratuity, and is it billed automatically? Some contracts include automatic gratuity. Some leave it to you. Either is fine — you just need to know which.
- Is sales tax applied to the food subtotal, or to the food subtotal plus service charge? The second is more common and slightly more expensive.
- What is the minimum spend, and what happens if my guest count drops below it? Most venues require a minimum food and beverage spend. If you booked for 175 and 160 confirm, you may still owe the 175-guest minimum.
How do I avoid this on every other vendor?
The plus-plus trap isn't unique to catering. Florists charge delivery fees. DJs charge overtime. Photographers charge for extra hours and album upgrades. Venues charge for setup, breakdown, and chair rental that you thought was included.
This is what actually works: build your budget around the final invoice for each vendor, not the headline quote. Every line item gets its own row — base price, service charge, gratuity, tax, delivery, overtime — and the total of those rows is what you compare against your category cap.
A wedding budget spreadsheet that tracks each fee on its own line will catch this every time. You enter the quote when it comes in. You add the service charge, gratuity, and tax as separate rows. The sheet adds them up and compares the all-in number to what you actually have to spend. The surprise disappears before the contract gets signed.
The bottom line
If a caterer quotes you $110 a plate, write down $140. If they quote $90, write down $115. The math is consistent across nearly every venue and catering company because the structure — base price, service charge, gratuity, tax — is standard in the industry.
The couples who don't get blindsided are not the ones who negotiate harder. They're the ones who treat the per-guest quote as the start of the math, not the end of it.
Want a spreadsheet that breaks every vendor invoice into its real line items — and tracks budget vs. actual against your category caps? The Wedding Budget Spreadsheet is built for exactly this. Plug in the quote, add the service charge and gratuity rows, and you'll see your real number before you sign.
