Open →Minecraft keeps its systems close to the surface: XP, enchanting levels and crop-like mechanics all run on fixed formulas. Our tools apply them exactly — the same math the game uses — so the number you see is the number the game uses.
New calculators land here as the toolkit grows. If a number in the game annoys you, request it — most Minecraft tools take us days, not weeks.
Know which crop pays before you plant — gold per day, harvests and season math.
Open →Marketplace cuts, DevEx rates and pricing math for Roblox creators.
Open →Breeding maths, power ladders and combo data.
Open →OSRS XP curves, level targets and skilling math — computed from the game's own experience formula, not copied from a table.
Open →Production planning for Satisfactory: node output, belt throughput and machine counts, worked out from the recipes.
Open →Factorio production planning: machines from a target rate, belts from machine demand — the ratios, computed.
