Game Supplies Calculator — Party Games Kit
Work out supplies and prizes needed for party games and activities.
How We Calculate This
This calculator estimates total game supply and prize costs for your party.
Formula
- Supply cost = number of games × supply cost per game
- Total prizes = games × prizes per game, rounded up after adding the spare-prize buffer (default 10% for ties, re-matches and consolation)
- Prize cost = total prizes × cost each
- Grand total = supply cost + prize cost
- Cost per child = grand total ÷ number of children
Frequently Asked Questions
Plan 4-6 games for a 2-hour party. That is roughly one game every 15-20 minutes, with breaks for food and cake. Have 2-3 backup games in case some finish quickly or the children are not engaged. Alternate between active games and quieter ones.
Musical bumps/statues (ages 3+), pass the parcel (all ages), treasure hunt (ages 5+), relay races (ages 5+), musical chairs (ages 4+), and sleeping lions (ages 3+). For older children (7+), try team challenges, scavenger hunts, or craft activities.
Have 2-3 prizes per game (winner plus runners-up). For pass the parcel, every child should win a small prize. For very young children (under 5), consider giving everyone a small prize for every game to avoid tears. Budget £0.50-£2 per prize.
Musical games need a speaker. Pass the parcel needs wrapping paper and small prizes. Treasure hunts need clues and a prize. Relay races need markers. Most games need very little equipment. Keep supplies simple and reusable where possible.
