Craft Build Cost Estimator
Know what you'll spend before you spend it. Pick a build type, adjust materials, and get a realistic total with a safety buffer for the things you'll inevitably forget.
Track the real numbers as you build
This calculator gives you a starting estimate. Costumary tracks your actual spending, materials, timeline, and progress across every build, all in one workspace.

How much does a cosplay cost to make?
A basic closet cosplay costs $30–80. A sewn costume runs $100–300. A full EVA foam armor build typically costs $200–500 in materials. Complex multi-component builds with LEDs and 3D printing can exceed $800. Use the calculator above with your actual material choices for a realistic estimate.
How much does a fursuit cost?
Materials for a partial fursuit (head, paws, tail) cost $200–500 for faux fur, foam, adhesive, and eyes. A full digitigrade suit runs $500–1200 in materials alone. Commissioned fursuits range from $2,000–$8,000+ because of the 100+ hours of labor involved.
How do I budget for a sewing project?
Start with fabric (typically 60–70% of cost), then add thread, interfacing, closures, and notions. A simple garment from quilting cotton costs $20–50. A lined wool jacket runs $80–200. Always add a 15–20% buffer for muslins, mistakes, and forgotten notions.
How much does a Gunpla build cost?
A High Grade snap-build costs $15–30 for the kit alone. A fully painted Master Grade runs $50–120 including primer, paints, panel liner, and topcoat. Custom painted Real Grades with weathering can run $80–150 in total materials.
What does LARP armor cost to make?
A basic foam LARP kit (tunic, belt, one prop) costs $50–120. Leather armor runs $150–400 for vegetable-tanned leather, hardware, and dye. A complete character kit with layered garb, armor, and accessories typically costs $300–600.
Why do craft builds always go over budget?
Builders forget consumables (adhesive, sandpaper, primer), underestimate fabric yardage for pattern matching, and don't account for tool costs on first builds. This calculator includes a configurable safety buffer and a 'forgotten items' reminder to help prevent overruns.
