Oxygen Not Included Calculators

Oxygen Not Included Calculators

Plan your colony with precise, up-to-date numbers. Four calculators — farm, food, ranch, and geyser — built on data extracted directly from the live game, so they stay current with every DLC including the Aquatic Planet Pack.

Farm Calculator Crop grow time, seeds, water, fertilizer, light and yield — with Wild, Farmer’s Touch, mutations and pollinators.Food Calculator Calories per cycle and the full ingredient breakdown down to raw crops and materials, with spoilage and spices.Ranch Calculator Eggs, meat, byproducts, ranch capacity and the happiness/fertility from grooming, fountain and condo.Geyser Calculator Average output, taming rolls, dormancy storage, cooling, oxygen and power for every geyser, vent and volcano — with geotuning.

Built on live-game data — current with every DLC

Most Oxygen Not Included calculators are hand-maintained and drift out of date. This one extracts crop, critter, food, recipe and building data straight from the running game, so the numbers match what you see in-game and update with each patch — including the latest Aquatic Planet Pack.

What’s included

  • 36 crops — grow time, water, fertilizer, light, temperature and yield.
  • 64 critters — diet, eggs, meat, byproducts, lifespan and happiness.
  • 65 foods — calories, quality, ingredients and spoilage.

The calculators

The farm calculator sizes any crop to a target output. The food calculator turns a duplicant count into the full ration supply chain. The ranch calculator plans critter ranches — eggs, meat, capacity and the happiness mechanics that older tools predate. The geyser calculator analyzes any geyser, vent or volcano — average output, taming, dormancy storage, cooling and power. They cross-link, so a food’s ingredients open in the farm calculator and a critter’s feed opens preconfigured.
