Event Budget Allocation

Excel Formulas › Events & Catering

All versionsROUND

Split a total event budget across categories by percentage — venue, catering, photography, flowers. Each line is the budget times its percent, tied out so the categories sum to the total.


Quick formula: a category's budget allocation:
=ROUND(total_budget * category_percent, 0)
Total budget times each category's percentage; make the last line a remainder so it ties to the total.

The example

$30k budget, 45% catering.

2Catering 45%$13,500
3Venue 25%$7,500

The formula

The formula:

=ROUND(total_budget * category_percent, 0) // budget × category %

How it works

How it works:

  1. Assign each category a percent of the total (they should sum to 100%).
  2. Each line = ROUND(total_budget × percent, 0).
  3. Make the last line a remainder — total - SUM(others) — so it ties out exactly.
  4. Track actual vs budget per category to catch overruns as you book vendors.

Common wedding splits run roughly: catering ~40–50%, venue ~20%, photography ~10–12%, flowers ~8%, attire/music/misc the rest. Start from percentages, then convert to dollars and adjust — it keeps the plan balanced and makes trade-offs explicit when one category creeps up.

Last as remainder

Tie-out:

=total_budget - SUM(other_lines)

Per guest

Budget ÷ guests:

=total_budget / guest_count

Actual vs budget

Variance:

=actual - budgeted

Pitfalls & errors

Tie to the total. Make the last line a remainder so allocations sum exactly.

Percents sum to 100%. Verify before trusting the split.

Leave a buffer. Hold ~5–10% for surprises.
