What contingency costs should I budget for events?

Preparing for unexpected event costs

A contingency budget protects your event from unforeseen expenses like vendor cancellations, technical failures, or weather-related changes. Planning a realistic contingency reduces last-minute scrambling.

Common contingency items:

  • Emergency vendor replacements (AV, catering)
  • Weather-related expenses (tents, heaters, fans)
  • Overtime labor charges and security
  • Additional transportation or accommodation needs
  • Permit or licensing unexpected fees
  • Refunds or ticketing disputes

How much to set aside:

  • For most events, reserve 10–15% of the total budget for contingency.
  • For high-risk events (outdoor in bad weather months or complex productions), consider 15–20%.

Management tips:

  • Track contingency use separately so you can analyze causes after the event.
  • Negotiate vendor flexibility clauses (e.g., reduced penalties for rescheduling).
  • Have backup plans for key elements—alternate AV suppliers, backup generators, or rain venues.

Clear internal protocols help too: designate who can approve contingency spending and under what conditions. That speed of decision-making keeps problems from escalating into larger costs.
