Wedding Budget Calculator United States
Use this wedding budget calculator to split your total budget across venue, catering, attire, photography and more by percentage, and see your cost per guest.

What it does
The Wedding Budget Calculator splits your total wedding budget across the main spending categories by percentage and shows your cost per guest.
Data sources & parameters
This calculator uses standard financial formulas and runs entirely in your browser. It needs no external rate data — your result is computed only from the values you enter above.
We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.
The formula
Category amount = total budget × category %; cost per guest = total budget ÷ guests
How it works
It multiplies your total budget by the percentage you set for each category, sums the allocations, and divides the budget by your guest count.
Where it is used
- Splitting a wedding budget across categories
- Finding the cost per guest
- Spotting an over- or under-allocated plan
Worked example
On a $30,000.00 budget for 120 guests, that is … per guest, with … going to venue and catering.
What the wedding budget calculator does
Enter your total budget and guest count, then set the share of the budget for each major category. The wedding budget calculator multiplies the budget by each percentage, shows the amount for each category, and gives your cost per guest.
Wedding costs are spread across many vendors, and without a plan it is easy to spend too much early on a venue and leave too little for photography, flowers or entertainment. Allocating the budget first gives each category a limit before you sign any contracts.
Categories and a starting split
The categories are venue and catering, attire and beauty, photography and video, flowers and decor, music and entertainment, and "other" for stationery, favors, rings and the many small items that add up. Venue and catering is almost always the largest, so the default weighting leans that way.
A common starting point is roughly 40 percent for venue and catering, 10 to 12 percent for photography and video, 8 to 10 percent each for attire, flowers and entertainment, and the rest for everything else. These are planning rules of thumb. Use the advanced fields to change them: if photography matters most to you, raise its share and lower another.
Cost per guest
Much wedding spending rises with the number of guests: each one adds a meal, a place setting, rentals, favors and sometimes a bigger venue. Dividing the total by the guest count shows this in one figure. Trimming the guest list, even slightly, cuts several categories at once and usually saves more than shaving a little off each vendor's quote. If you want a large celebration, the per-guest figure shows whether your headcount and budget fit together.
Allocation and contingency
Your percentages do not have to add up to 100. Anything left over appears as unallocated, which you can keep as a contingency reserve for vendor overtime, last-minute additions, weather backups and easily forgotten tips. If the percentages add up to more than 100, the unallocated figure turns negative, a sign the plan is overcommitted. Allocating 90 to 95 percent and holding the rest back leaves room for real invoices.
Building a plan you can follow
Start with a total you can spend without borrowing, then a realistic guest count, then percentages that reflect your priorities. A couple who cares most about food and a good band will weight categories very differently from one focused on the dress and the venue.
Update the percentages as quotes come in so you always know how much is left in each category and whether an upgrade in one area means a cut in another. Use the calculator at the start of planning, before a venue takes 60 percent of the budget, again whenever the guest list changes, and when weighing a vendor's quote against what that category should cost. You can also compare a lavish version and a lean version side by side.
