The Forge Calculator is a community-built crafting helper designed for players of the Roblox game The Forge. Updated for December 2025 with all 40+ ores including Galaxite, crystal ores, and the latest additions.
By selecting different ores (maximum 4 types as per game rules), the calculator estimates your average multiplier, forge purity, and composition breakdown. High-tier ores generally improve forge effectiveness, while mixing low-value materials can dilute results. The purity indicator highlights whether your ore mix is focused or inefficient.
New Features: Trait activation display shows which ore bonuses will apply to your forge (requires 10%+ of that ore). Composition percentages help you understand exactly what you're crafting with.
