Quick answers
Frequently asked questions
Does the calculator subtract intermediate items from inventory?
Yes. Existing components and intermediate crafts are consumed before their recipes are expanded.
Why can the result include a small surplus?
Rust recipes create fixed batch sizes. The planner rounds up complete batches and keeps the extra output available to later recipe steps.
Does crafting time include parallel players or workbench speed modifiers?
No. It totals the listed base crafting time for one sequential queue.
