About Calc Den
Free Steal an Egg income, weight and speed calculators
Calc Den is a free, unofficial browser tool for players of Steal an Egg on Roblox. The income calculator estimates earnings from pet weight and colour mutation, works backwards from a target income, and totals a pen of pets. A separate speed calculator compares treadmill and trail upgrades and estimates steps to each biome. Reference pages cover pet income, mutations, treadmills and trails. Some community records lack base weights, so the calculator lets users enter a size ratio or estimate a missing base weight from displayed pet statistics. Source links, dates and limitations are provided; results may differ after game updates or because of rounding. No account, download or payment is required. Calculations run in the browser. This is an independent fan project built with AI assistance, not affiliated with Roblox or the game developers.
