What Is a Wedding Budget Allocator?
This calculator splits a total wedding budget across the categories couples typically spend on — venue and catering, photography, attire, flowers, entertainment and more — using commonly-cited planning percentages as a starting point.
Every percentage is editable, so you can shift the split toward what matters most to you (a bigger photography budget, a smaller favors budget) while keeping the math and the running total in sync.
How to Read Your Results
Cost Per Guest
The venue-and-catering dollar amount divided by your guest count — often the single most useful number when deciding whether to trim the guest list or the budget.
Category Breakdown
Each category's dollar amount, calculated directly from your total budget and its percentage.
Percentages Total
A running check that all category percentages add up to 100%. If it doesn't, part of the budget is unallocated (or over-allocated) and the percentages need adjusting.
Real-World Example
A $30,000 budget for 100 guests, using the starting guideline percentages:
| Category | % | Amount |
|---|---|---|
| Venue & catering | 45% | $13,500 |
| Photography & video | 12% | $3,600 |
| Music & entertainment | 8% | $2,400 |
| Attire & beauty | 8% | $2,400 |
That puts venue and catering cost per guest at $135 — a useful check against per-head quotes from venues and caterers.
Tips for Building a Wedding Budget
- Decide your top 2-3 priorities first (often venue, photography, or entertainment) and shift extra percentage toward them.
- Guest count has an outsized effect on total cost — cutting the list is usually the single biggest lever on the total budget.
- Keep a real contingency — the miscellaneous category exists for a reason, since unexpected costs are common.
- Re-check the percentage total every time you adjust a category so the full budget stays allocated.
