ForgCalcs.com was created by a team of dedicated Roblox The Forge and Forge of Empires players who were tired of doing forge math by hand. We built the tool we wished existed — accurate, fast, and completely free.
Our probability models are built on community-verified data and statistical analysis of real game outcomes. We're committed to keeping the calculator updated with every major game patch.
We are not affiliated with Roblox Corporation or InnoGames. This is an independent fan tool created for the community.
Our Mission
We believe every player deserves access to the same information that top players use to make optimal forge decisions. Forge math is complex — ore stacking, trait thresholds, world multipliers, Arc bonuses — and doing it correctly without a tool takes significant time and expertise. ForgCalcs.com makes this analysis instant and accessible to everyone, from first-time players to veteran theorycrafters.
What We Cover
Our Roblox The Forge calculator covers all 48+ ore types across World 1 through World 4 and The Peak, with up-to-date trait data, rarity thresholds, and world-specific modifiers. The Forge of Empires section provides a full Arc Calculator, Great Building investment planner, and P1–P5 reward tables with real-time Arc bonus computation.
Data Accuracy
All game data is sourced from community playtesting and cross-verified across multiple sources. We update within 48 hours of any major patch. If you spot an inaccuracy, please reach out via our Contact page — community corrections help make the tool better for everyone.
Privacy & Independence
ForgCalcs.com is fully independent. We run no advertising, collect no personal data, and require no account or login. The calculator operates entirely in your browser. We're funded purely by our passion for these games and this community.
