How does the crafting cost calculator expand recipes?

It walks the recipe tree recursively. A chest needs 8 planks, planks come from logs at 4 per log, so the tool reduces the chest to logs. It keeps expanding every intermediate item until only base resources remain, then sums identical materials across the whole tree.

How many logs does a crafting table take?

A crafting table needs 4 planks, and 1 log yields 4 planks, so a single crafting table costs 1 log. The tool always rounds up at each conversion because Minecraft does not give fractional items, so partial logs become whole logs.

Does this account for items that come in batches?

Yes. Many recipes output more than one item, like planks giving 4 per log or sticks giving 4 per 2 planks. The tool divides the needed amount by the batch yield and rounds up, so you never under-gather, matching how crafting works in game.

Can I plan a big build with this?

Yes. Set the quantity to the number of items your build needs, for example 27 chests for a storage wall, and the tool scales the entire material list. Combine items by running the tool for each component and adding the raw-material totals together.

Why is the raw material count rounded up?

Minecraft items are whole units, so you cannot mine half a log or half an ingot. At each conversion the tool rounds up to the next whole base resource. This guarantees the gathered amount is always enough, with at most a small surplus from batch rounding.

Starting a big Minecraft build without knowing the material cost means endless trips back to the mine. This calculator expands an item’s full recipe tree down to raw resources — logs, ingots, diamonds, redstone — and totals them so you can gather everything in one trip and craft without interruption.

How it works

The tool treats each recipe as a tree and reduces it recursively until only base materials remain, rounding up at every batch conversion because Minecraft items are whole units:

need(item, qty):
  if item is a base resource → add qty to totals
  else for each (ingredient, count) in recipe(item):
        batches = ceil(qty / recipe.yield)
        need(ingredient, batches × count)

For example a chest reduces to 8 planks, planks reduce to logs at 4 per log, so one chest costs ceil(8 / 4) = 2 logs of planks — and the tool then folds the extra surplus from rounding into the displayed total.

Tips and example

A single chest needs 8 planks; at 4 planks per log that is 2 logs. Make 27 chests for a storage wall and the tool reports 54 logs. A beacon expands into 5 glass, 3 obsidian, and 1 nether star, with glass reducing to 5 sand smelted. Run the tool once per component of a build and add the raw totals to get a single shopping list for your whole project.
