| Food, cake, and drinks | This is the baseline spend every party feels, even when the event stays at home. | Pizza, custom cake choices, add-on desserts, drink variety, and refill buffer raise this lane first. | Pizza & Cake Calculator |
| Venue or activity spend | The total jumps fastest when the party leaves the house or adds a paid activity lane. | Play places, entertainers, craft stations, and booking minimums push the budget up much faster than extra snacks do. | Party Budget Calculator |
| Decor, favors, and table styling | These items often feel optional at first, but they stack quickly once themes and take-home items show up. | Balloon installs, themed plates, party favors, signage, and photo-friendly extras quietly widen the gap between a simple and a premium party. | Party Budget Calculator |
| Drinks, ice, and paper goods | Support items are easy to miss because they are rarely the headline purchase, but they still show up in the cart. | Water, juice boxes, soda, ice, cups, napkins, plates, and trash flow usually determine whether the party feels underplanned at the end. | Party Drink Calculator |
