Farthest Frontier tools

What these Farthest Frontier tools do

Farthest Frontier punishes guesswork. A village that looks fine in August can starve in February because half the harvest was cabbage that rotted in the root cellar, or freeze because nobody checked how much firewood the houses burn. These pages turn the numbers the community wiki has pulled from the game into answers you can use while you play.

• Food and crop field calculator: type in your population and a three-year rotation. It tells you how much food the village eats, how much one field grows, how many fields you need, and whether the rotation is wearing the soil down.
• Firewood and fuel calculator: adds up what your homes and fuel-burning workshops use, then converts it to logs and logging camps.
• Production chain lookup: pick any crafted good, from bread to platemail, set a yearly target and get the full chain as a diagram, with every raw material and how many cycles each building runs.
• Buildings list: all 98 buildings with tier, size, build work, materials, output, workers, what unlocks them and their effect on desirability.
• Resources and goods list: every resource with its recipe, what it is used for, how many months it keeps in storage and how long tools and clothes last.
• Food guide, crop rotation guide and food spoilage guide for the reasoning behind the numbers.

The three things that end most villages

Food that rots before it is eaten. Fresh meat and fish keep 3 months on Vanquisher, bread and greens 6, while smoked meat keeps 24 and cheese 36. A big harvest is only worth what the village eats before it spoils. The spoilage guide has the full table, the storage multipliers and the barrel math.

Fields that wear out. Every wheat planting takes 8 points of fertility off the field and leeks or rye take 6. Clover gives back 3 and compost 6, but only after the field's Environment Fertility Factor cuts them down. The crop rotation guide shows rotations that hold the soil, and the food calculator checks yours.

Heavy tools. The Windmill, Foundry, Blacksmith Forge, Furniture Workshop, Glassmaker and Saw Mill upgrade each need 1 Heavy Tool to build. A Heavy Tool is 15 iron ingots and 5 coal at a Blacksmith Forge, and the ingots are 5 iron ore and 2 coal per 5 at a Foundry. Plan the iron chain before you need it:

Where the numbers come from

Crop output, fertility changes, growing days and loss chances come from the crops table in the Farthest Frontier Wiki farming article, which is marked as updated for version 1.1.0. Building costs, workers and tiers come from the wiki's Buildings article, spoilage from its Resources and Spoilage articles, and recipes from each item's wiki page. Food per villager and the best-case output of hunters, foragers, barns and orchards come from the wiki's "Food, by the numbers" article, which a player measured in version 0.9. The game is on version 1.1.0 as of April 2026, so a patch may have moved a number or two. Every page lists its sources at the bottom.

Some numbers we could not find in any source, like how much firewood one house burns in a winter. Where that happens, the calculator asks you to read the figure from your own Annual Report instead of making one up. Where two sources disagree, as they do on barrels, we say so on the page.
