Start your buildHow to budget for a convention
Convention costs sneak up on you. The badge is the easy part. It is the hotel split, the parking you forgot to check, the $16 chicken tenders at the convention center, and the artist alley prints you could not walk past that blow your budget. Most first-time con-goers underestimate their total spend by 40 to 60%.
The real cost breakdown
For a typical 3-day convention, lodging is your biggest expense (30 to 40% of total), followed by food (20 to 25%), then badge and shopping split the rest. If you are driving, gas and parking add $40 to $100 depending on distance. If flying, budget $200 to $400 for airfare plus $30 to $60 for airport-to-hotel transport each way.
How groups save money
Hotel rooms are the biggest savings lever. A $150/night room split four ways is $37.50 per person per night. Carpooling cuts gas and parking costs. Group dinners at sit-down restaurants are cheaper per person than everyone buying convention center food individually. The calculator above splits shared costs automatically when you set a group size larger than one.
First convention vs. repeat attendee
Your first convention is more expensive because you are buying things you will reuse: a rolling suitcase for cosplay transport, a repair kit, comfortable walking shoes, a portable charger. By your third convention, your base costs drop because you already own the gear. The variable costs (badge, hotel, food, shopping) stay the same.

Goku
~4wThe most iconic anime hero: the orange gi, the blue undershirt, the spiky black hair. Goku's look is a martial arts uniform with Saiyan flair, and it's one of the most recognized cosplays on any con floor. This template covers the full outfit: the wrap-front gi top, the blue wristbands and obi, the boot covers, and the gravity-defying wig. 7 components, 10 materials with cost estimates, a 12-step build plan, and a realistic 4-week, $70 to $200 budget.


Jinx
~6wArcane's chaos gremlin in full: the blue braids, the cloud tattoos, the crop top and belt rig, and optionally Pow-Pow. The braids are the make-or-break detail, 140cm of synthetic fiber that will drag the floor and pull the wig off your head if you don't support them properly. The tattoos take real planning too, whether you paint them on or build armsocks. 6 components, 13 materials, ~6 weeks, $120-320.


Hatsune Miku
~5wVocaloid's iconic digital diva, built around four instantly recognizable details: the floor-length teal twin-tail wig, the grey school-uniform top and pleated skirt, the detached black sleeves, and the headset with mic. This is an intermediate build where the wig is the star component, and every garment has a signature teal trim. Includes 7 components, 16 materials with cost estimates, a 14-step build plan, and a realistic 5-week, $100 to $300 budget.


Wednesday Addams
~6wNetflix's darkly witty Nevermore student in her signature black and gray uniform, double braids, and pale ghostly makeup. The Nevermore uniform is a custom design (not standard plaid), and the braids demand wig stability work. 7 components, 13 materials, a 6-week build plan accounting for wig testing and makeup practice, budget $85 to $220.
