Party Decoration Budget Calculator
Budget the areas that create the most visual impact before spending on small decorations everywhere.
What counts as an impact zone?
Examples include the entrance, cake/food table, backdrop/photo area or one main room feature. Your party may need one, three or none; the number is editable.
Why no “average decoration spend” is forced
Decoration prices vary with DIY versus hired décor, venue, materials and theme. Enter your real prices or quotes and keep the spending ceiling visible.
