MemorraA wedding for 100 guests costs most couples somewhere between 20,000 and 40,000 dollars in the United States, and the single largest chunk is almost always food and drink, which tends to run 40 to 50 percent of the total. The rest divides across the venue, photography, attire, flowers, music, and the many smaller lines that add up quietly. What matters more than the grand total is how the money splits, because the percentages hold fairly steady whether your budget is 20,000 or 60,000. If you know that catering is roughly half and photography is roughly a tenth, you can size every other line and spot when one category is quietly eating the rest. Here is a category by category breakdown for 100 guests, with the ranges couples actually land in.
Where does the money go?
These percentages are a starting point, not a rule. Your venue, your city, and your priorities will shift them.
| Category | Typical share | On a $30,000 budget |
|---|---|---|
| Catering and bar | 40 to 50% | $12,000 to $15,000 |
| Venue | 10 to 15% | $3,000 to $4,500 |
| Photography and video | 10 to 12% | $3,000 to $3,600 |
| Flowers and decor | 8 to 10% | $2,400 to $3,000 |
| Music or DJ | 7 to 10% | $2,100 to $3,000 |
| Attire and beauty | 5 to 8% | $1,500 to $2,400 |
| Everything else | 8 to 12% | $2,400 to $3,600 |
Catering is the line that scales directly with guest count, which is why cutting your list is the fastest way to cut your budget. Trimming 100 guests to 80 does not just save on 20 meals, it saves on two tables of rentals, more flowers, more invitations, and more of the bar.
What is the cost per guest?
Divide the food and drink budget by your headcount and you get the number that actually moves with your list. At 100 guests, plated dinners with a bar commonly land between 120 and 200 dollars per guest once you include the meal, alcohol, service, and tax and tip. Buffets and stations can come in lower, and a full open bar pushes it higher. Knowing your per guest number makes every add to the list a real decision, because one more guest is not free.
What do people forget to budget?
The lines that blow budgets are rarely the big ones. They are the pile of smaller costs nobody lists at the start: service charges and gratuity on catering, which can add 20 to 25 percent on top of the food quote, plus rentals, stationery, an officiant, hair and makeup, and the marriage license. Read every vendor quote for whether tax and gratuity are included, because a 12,000 dollar catering quote can become 15,000 once they are added.
How to keep the budget honest
A budget only helps if you update it as real costs come in, and a spreadsheet you set up once and never touch will drift. Memorra tracks your total against actual spend by category, so you can see at a glance whether catering is on track or quietly over. As you book vendors and log deposits, the numbers update, and because your guest count lives in the same place, you can see how adding guests moves your spend. That is the difference between a budget you set and a budget you actually keep.
