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.

Marin Kitagawa
~5wThe cosplay enthusiast from My Dress-Up Darling in her school uniform: the sailor top, the impossibly long pink wig with twin tails, and the layered styling that requires real wig management. The wig is the entire build - long enough to drag on the floor without support, heavy enough to slide backward even with clips. 6 components, 12 materials, ~5 weeks, $85-220.


Yor Forger
~6wSpy x Family's Thorn Princess in her iconic red dress, gold headband, and long black wig. The dress is a form-fitting strapless bodice with a thigh-high slit and detachable train, so it needs boning and modesty engineering that budget costume sets skip entirely. This template covers 7 components, 12 materials with cost estimates, a 12-step build plan, and a realistic 6-week timeline at $120 to $300.


Ryomen Sukuna
~6wJujutsu Kaisen's most powerful sorcerer and the series' primary antagonist: the deep red spiky hair, intricate facial tattoos, black standing-collar kimono with red flame patterns, and long black nails. A intermediate build requiring solid body paint application, wig styling, and garment construction. 6 components, 12 materials, ~6 weeks, $150-350.


Kenjaku
~9wJujutsu Kaisen's ancient sorcerer Kenjaku inhabits Suguru Geto's body, distinguished by an exposed brain prosthetic mounted on the head and a stitched scar across the forehead. The signature brain piece is a weeks-long build requiring tissue paper, PVA glue, and careful paint work, while the Geto uniform and long black wig complete the iconic silhouette. 5 components, 13 materials, ~8-10 weeks, $180-380.
