Event Budget Calculator
Build a complete event budget from venue, catering, entertainment, decor, and staffing costs. Enter values for instant results with step-by-step formulas.
Formula
Category Budget = Total Budget x Allocation Percentage
Event budgets are allocated by percentage to each category based on industry standards for the event type. Catering typically gets the largest share (30-35%), followed by venue (20-25%). A 5% contingency fund is always recommended. Cost per guest is calculated by dividing the total budget by the guest count.

Frequently Asked Questions
How do I create an event budget?
Start by determining your total budget, then allocate percentages to each category based on event type. The biggest costs are always venue (20-25%) and catering (30-35%). Use the 50/30/20 approach as a starting point: 50% for essentials (venue + food), 30% for enhancements (entertainment, decor, AV), and 20% for everything else (marketing, printing, contingency). Track actual expenses against your budget throughout the planning process. Always include a 5-10% contingency fund for unexpected costs.
What percentage of my event budget should go to catering?
Catering (food and beverages) typically represents 30-40% of the total event budget — the single largest expense category. For corporate events, budget 35% for catering. For social events like birthdays, 30-35% is typical. For fundraisers, aim for 25-30% to keep costs lower and maximize fundraising returns. If you're trying to reduce catering costs, consider: brunch or lunch instead of dinner, buffet instead of plated service, limited bar instead of open bar, or appetizer-focused receptions.
How can I reduce event costs without sacrificing quality?
Key cost-saving strategies: Choose off-peak days (weekdays cost 20-40% less), book during off-season months, negotiate package deals with venues that include catering, use in-season flowers and local vendors, opt for a DJ instead of a live band, use digital invitations, choose a venue that needs minimal decoration, serve brunch instead of dinner, and leverage volunteer help for setup/cleanup. You can also reduce the guest list — every guest removed saves $75-$200+ in per-person costs.
