Pick the output rate first
Start with the item you actually need, then choose a per-minute rate that matches your base goal instead of guessing from raw materials.
Arknights: Endfield production planner
Endfield Calculator
Plan factory output, material dependencies, facility counts, and power draw from one browser-based calculator. Add a target item below and the planner expands the full production chain for you.

Practical workflow
Build from targets, not guesswork
Endfield production planning becomes easier when each machine is treated as capacity. The calculator keeps the math visible, so you can compare output goals, power pressure, and raw material assumptions before rebuilding a factory line.
Read facility counts as capacity
A result of 2.4 facilities means two machines are fully occupied and one more machine needs 40 percent uptime.
Use the tree for bottlenecks
Tree view is best for spotting deep dependencies, repeated ingredients, and loops before you commit to a layout.
Switch materials to raw when needed
If you already farm or stockpile an ingredient, mark it as raw to compare the real build cost for your current base.
Calculation method
The planner exposes the factory math
Every recipe is reduced to an output-per-minute rate. The app then expands dependencies, totals facility utilization, adds power requirements, and marks ingredients as raw only when they have no recipe or you choose to treat them that way.

Quick answers
Is Endfield Calculator official?
No. It is an unofficial fan-made planning tool. Arknights: Endfield and related IP belong to their respective owners.
Why do some results show decimal facilities?
Decimal counts represent utilization. For example, 0.5 means one facility running half the time, while 3.25 means four facilities if you want continuous throughput.
Does the calculator handle loops?
Yes. The planner detects circular recipe chains and uses linear solving when a loop can be balanced by the available recipes.
Unofficial fan project with community-maintained calculations.
Recipe overrides and raw-material toggles help compare multiple base assumptions.
Tree and table views make dependency chains readable on desktop and mobile.
