How to build a wedding budget, and where the money really goes

The Knot’s 2026 Real Weddings Study surveyed 10,474 US couples who married in 2025. It puts the average wedding at $34,000, about flat on the year before, with an average of 117 guests and $292 spent per guest. The average couple hired 13 wedding professionals.

Zola’s 2026 First Look Report, which surveyed more than 11,500 engaged couples, puts the average budget at $36,000. The two are not measuring the same thing. The Knot asks couples what they spent after the wedding; Zola asks couples who are still planning what they expect to spend. Both companies sell wedding services, so read them as industry surveys, not government statistics.

Averages are pulled up by a few very expensive weddings. MoneyLion’s summary of The Knot’s study gives a median of $24,000, with a quarter of couples spending $12,000 or less and a quarter spending over $41,000. Where you marry and how many people you invite matter more than any national number.

In the UK, Hitched’s 2026 report on 2,020 couples gives an average of £21,990 and £272 per guest, with London about 12% above the national figure.

The venue and the food are the budget. In The Knot’s sample breakdown, reported by U.S. News, venue and rentals take 29% and catering, cake and drinks another 24%. Photography and video come next at 10%, then flowers and decor at 9%. Everything else is single digits.

Planners say the same from the other side. Karen Pecora, an event planner in Pennsylvania, told U.S. News she has couples set aside 48% to 54% of the whole budget for venue, food and drink. If your venue and catering quotes already eat 70% of your number, the rest of the plan will feel starved, and that is the moment to rethink the venue or the guest list, not the flowers.

MoneyLion’s rundown of 2025 spending lists the reception venue at about $12,900 on average and catering at about $80 a person, which gives you a quick check on any quote you receive.

Most of your costs are priced per head: meals, drinks, chairs, linens, invitations, postage, favors. At The Knot’s $292 a guest, each table of ten is roughly $2,900. Cutting 20 guests will not save the full $5,840, because the venue and photographer cost the same either way, but the per-head lines fall straight away.

Hitched found the same pattern in the UK: couples with 101 or more guests spent £35,591 on average, nearly 40% above the national figure. Fix a guest number before you sign anything, and price every quote at that number.

Service charges are the big one. Caterers and venues often add a service fee of 18% to 25% on food and drink, and sales tax on top. Here Comes The Guide, a venue directory, says tax and service together usually take 23% to 33% of the food and drink budget. A service charge is not always a tip, so ask in writing whether staff gratuities are included.

Then the smaller lines that add up: tips for hair and makeup, delivery crews, drivers and bartenders; dress or suit alterations, which can run from a few hundred dollars to over $1,000; hair and makeup trials; meals for the photographer, DJ and planner, which some contracts require; your marriage license and certified copies; and the last-minute supplies nobody budgets for.

Postage surprises people too. Since October 4, 2026, a 1-ounce stamped letter costs $0.82, each extra ounce $0.29, and a square or rigid envelope pays a $0.49 nonmachinable surcharge. Take a finished invitation to the post office to be weighed before you buy stamps, and remember the stamped reply envelopes.

Before you sign, ask every vendor for an all-in price that includes tax, service, delivery, overtime and any fees.

Start with the total you can pay without debt: savings, what you can set aside each month until the date, and any family money that has actually been offered. Then set the guest count. Then divide the total by the shares in the table above and adjust for what you care about.

Hold back a buffer before you allocate anything. Lisa Lafferty, a Beverly Hills planner, told U.S. News to expect to spend 10% to 15% more than your budget. In the UK, Hitched found 56% of couples overspent. Keep the buffer out of the category numbers, so nobody mistakes it for spare money in the flowers line.

Track every deposit and due date in one place, and keep the wedding money in its own account, as Pecora suggests, so you always know what is left.

Pick your top two or three priorities together and spend there. Cut hard everywhere else, rather than trimming every line a little.

Go after per-head costs first, since they multiply: a smaller guest list, a shorter bar menu, fewer courses. The planners U.S. News spoke to also suggest digital invitations, renting arches and decor rather than buying, skipping favors (at $15 each for 120 guests, that is $1,800), and choosing a venue that is already furnished rather than a bare field with a tent, which often costs more than expected.
