Each category is either a percentage of the total budget or a fixed amount; the calculator turns both into money, adds them up and shows what is left to allocate or how far the plan runs over. Budget per guest is the total divided by the number of guests, and the table gives each category's cost per guest.

With the defaults, 30,000 for 120 guests is 250 per guest, and the example split puts 45% (13,500) on venue and catering. For comparison, couples married in the US in 2025 spent an average of $34,000 on 117 guests, or $292 a head, according to The Knot's 2026 Real Weddings Study.

The default percentages are an example, not a rule; change them to your priorities. A line such as "Rings 2500" is read as a fixed amount and "Flowers 10%" as a share of the total.

## 자주 묻는 질문

### What is the average cost of a wedding?

$34,000 in the US in 2025, according to The Knot's 2026 Real Weddings Study, based on 10,474 couples married that year. The average guest count was 117 and the average spend per guest $292, up $8 from 2024. Couples hired 13 vendors on average.

### How do you calculate the cost per guest for a wedding?

Divide the total budget by the number of guests: 30,000 ÷ 120 = 250 per guest. The table does the same for each category, so venue and catering at 13,500 is 112.50 per guest. Only costs charged per head, such as catering, rise with each extra guest; a photographer or band booked for a fixed fee does not.

### How should you split a wedding budget?

Start from the total you can spend, give each category a percentage or a fixed amount, and keep a contingency line. The default split is 45% venue and catering, 12% photography and video, 10% flowers and decor, 8% each for attire and beauty, music and contingency, and 3% each for stationery, rings and transport, which adds up to 100%. Move percentages toward what matters most to you.

### What if the categories add up to more than the budget?

The calculator shows a negative amount left to allocate and a share allocated above 100%. For a 10,000 budget with Venue 80% and Band 3,000, the categories total 11,000, which is 110% of the budget and 1,000 over. Lower a percentage or a fixed amount, or raise the total, until the share allocated is 100% or less.
