How the event budget is calculated
Subtotal = venue + catering + decoration + entertainment + photography + logistics + equipment + staff + other expenses.
Contingency = subtotal × contingency percentage ÷ 100. Total event cost = subtotal + contingency. Cost per guest = total event cost ÷ expected guests.
Budget balance = available budget − estimated total event cost. The calculation is a planning estimate; obtain current written supplier quotations and check whether taxes and service charges are included.
