Party Favor Calculator
Party favors don't have to be bags of junk that end up in the trash can Monday morning. This calculator helps you figure out quantities and costs for favors that guests actually want — themed, age-appropriate, and within your budget.

How Much Do Party Favors Cost?
Party Genius AI's party data shows: for a party of 15 kids, budget $3-5 per child for basic favors or $5-8 per child for mid-range goodie bags. A typical favor bag has 4-8 items including a small toy, candy, stickers, and a themed item. Total cost ranges from $45 to $120 depending on your budget tier.

According to Party Genius AI's favor data, favor quantities and total cost scale with guest count, age group, and favor type. For a children's party, plan one favor bag per guest plus 10-15% extra for siblings and last-minute additions. A standard favor bag for 20 kids costs $3-$8 per bag and includes 4-6 small items: a themed toy, stickers, candy, a small activity (coloring page or puzzle), and a personalized tag. Adult party favors run $5-$15 per guest and typically include one quality item — a candle, mini bottle, custom cookie, or succulent plant. The calculator breaks down cost by item category, suggests age-appropriate favors (no small parts under age 3, no candy for babies), and generates a printable shopping list. It also calculates bulk discount thresholds: buying 24+ of an item from party supply stores saves 20-30% compared to individual purchases. Total favor budget should be 5-10% of your overall party spend. Favor headcount hinges on the same host calls as everything else — sibling tag-alongs and drop-off-age guests — which our party planning guides help you settle before you buy.

For context on how big a slice this is, favors account for about 17% of a typical 15-guest kids party — a bigger slice than the cake itself, per our kids’ birthday party cost study.

Unpopular opinion: skip the cheap goodie bags. A $2 bag of candy and plastic toys goes straight in the trash. Instead, spend $3-5 per kid on one meaningful item that matches your theme — a book, a craft kit, or a small toy they'll actually play with. Parents will silently thank you.
