Wedding budget calculator

Split a total budget into the standard categories, see which half of it the guest list actually moves, and find out what a catering quote really costs once the service charge and tax stack on. Real numbers, real math.

How the math works

The split is plain percentage arithmetic. Each category's dollar figure is the total budget times that category's share:

The percentages are a planning template, not a law. The one this calculator uses puts venue and catering at 45%, photography and video at 12%, attire and beauty at 9%, flowers and decor at 8%, music at 7%, rings at 4%, stationery at 3%, transportation at 2%, favors at 2%, and a miscellaneous-plus-buffer line at 8%. They sum to 100.

The part the template hides is which categories the guest list moves. Catering, decor, stationery, and favors scale with the head count — more guests, more plates, more centerpieces, more invitations. Photography, attire, rings, music, and transportation don't; they cost about the same for 80 guests or 180. The calculator adds up the scaling categories and reports them separately, because that number, not the grand total, is what a shorter guest list changes.

The catering mode uses a different formula — the one that turns a quote into a bill. The service charge is a share of the food-and-beverage subtotal, and the sales tax usually applies to the subtotal and the service charge. The two stack cleanly:

Worked example

Take a couple planning a 117-guest wedding — the U.S. average guest count — to the $33,000 national average cost. Split by the template, venue and catering take $14,850, photography and video $3,960, attire and beauty $2,970, flowers and decor $2,640, music $2,310, rings $1,320, stationery $990, transportation $660, favors $660, and a miscellaneous-plus-buffer line $2,640.

Now separate the two halves. The categories that scale with the guest list — catering, decor, stationery, favors — come to $19,140, close to 58% of the budget. The fixed categories come to $13,860. Across 117 guests that variable half works out to roughly $164 a head. That per-head figure, not the $33,000, is what a shorter guest list actually trims.

The catering mode makes the second point. Suppose the caterer quotes $150 a plate. For 117 guests that's a $17,550 food-and-beverage subtotal. Add a 22% service charge and an 8% sales tax that applies to the subtotal and the service charge together, and the bill lands near $23,124 — about $198 a plate, not $150. The simpler version: a plate quoted at $100 with a 20% service charge and a 10% tax on the combined amount bills at $132, a 32% markup on the sticker.

When this calculator is wrong

The percentage template is an average of averages, and almost no real wedding matches it. The clearest evidence is the guest-count data: weddings with fewer than 50 guests averaged about $15,000 in 2024, and weddings with more than 100 guests averaged about $42,000. That is nearly a threefold difference driven mostly by one input, so a template that treats the total as fixed and the categories as proportional is describing a wedding that may not resemble yours.

Other ways the number above misses:

• Region moves the total more than the mix does. The same event ran about $57,000 on average in New Jersey and about $18,000 in Utah in 2024. A national-average budget split is roughly threefold off in either direction before you change a single category.
• The service charge and tax aren't in the split. The $14,850 the template assigns to venue and catering is a sticker figure. Once an 18–22% service charge and sales tax stack on the food, the real catering bill is roughly a third higher than whatever plate price it implies.
• "Miscellaneous and buffer" is doing a lot of work. Marriage license, alterations, welcome bags, vendor meals, overtime, and the tips that a service charge doesn't cover all land here. An 8% line — $2,640 on a $33,000 budget — is usually where the plan and the spreadsheet part ways.
• The averages come from different distributions. The $33,000 average, the $284 average cost per guest, and the $12,900 average venue cost are separate cuts of the same survey, not figures that stack into one internally consistent wedding. Don't add them together and expect them to reconcile.

What to do with the result

Use the split to set expectations, then work the guest list, because that is the input that moves the total most. If the total is higher than the budget can carry, the fastest lever is the variable half: every guest you cut removes a plate at its real, service-charged, taxed cost — closer to $198 than the $150 on the quote in the example above. Trimming a fixed category like photography or music saves its sticker price once; trimming the guest list saves on catering, decor, stationery, and favors at the same time.

Then get every vendor quote in all-in terms — service charge, tax, and any expected gratuity included — before you compare them or slot them into the split. A caterer quoting $120 a plate before extras can cost more than one quoting $135 all-in. The sticker is not the number; the number is what clears your account.

Common questions

What percentage of a wedding budget goes to each category?

A common template puts venue and catering at 45%, photography and video at 12%, attire and beauty at 9%, flowers and decor at 8%, music at 7%, rings at 4%, stationery at 3%, transportation at 2%, favors at 2%, and a miscellaneous-plus-buffer line at 8%. These are a starting point; the real split shifts with your guest count and region.

How much does the average wedding cost?

The average U.S. wedding cost about $33,000 in 2024, down from $35,000 in 2023, covering the ceremony and reception but not the ring or the honeymoon. It's an average across a wide range — weddings under 50 guests averaged about $15,000 and those over 100 guests about $42,000 — so treat it as a rough anchor, not a target.

Why is my catering bill higher than the quote?

Most caterers add a mandatory service charge of 18–22% of the food-and-beverage subtotal, and sales tax usually applies to the subtotal and the service charge together. A $100 plate with a 20% service charge and a 10% tax on the combined amount bills at $132 — a 32% markup before any additional tip.

What's the single biggest way to cut a wedding budget?

The guest count. Close to 58% of a typical budget — catering, decor, stationery, favors — scales with the number of guests, while photography, attire, rings, and music stay roughly fixed. Cutting guests trims all the variable categories at once; cutting a fixed category saves its price only once.

Should I budget by percentages or by guest count?

Use both. The percentages tell you how to divide a total across categories; the guest count tells you how big the variable half of that total will be. Start from a realistic guest count and a real per-plate quote, and let the percentages check the mix rather than set the total.
