How do I open the calculator after crafting it?
Hold the 
Item Calculator Craft or 
Item Calculator Math and use it (right-click by default) to open its interface. The Craft calculator opens a recipe grid, while the Math calculator opens a plain number-entry screen.

The Craft calculator is built around a 
crafting grid and recipe lookups, so it's for planning what materials a recipe or chain of recipes needs. The Math calculator is a plain calculator for ratios, conversions, and multiplying or dividing quantities.

Open the Craft calculator and either fill the grid manually with the items and their counts, or import the recipe directly from your recipe viewer. Importing is faster and avoids typos in the grid.
How do I import a recipe from JEI or REI?
With the recipe visible in JEI or REI, use the mod's import key or button while the calculator is open to pull that recipe into the grid. Once imported, you can change the output quantity and the calculator scales the inputs.
Can it calculate materials for a recipe that needs other crafted items?
Yes — that's the main point of the Craft calculator. You set the recipe for the final item, then set recipes for the intermediate items it needs, and the calculator works down the chain to the base materials.
How do I change how many of an item I want to craft?
Set the desired output count on the recipe's output slot rather than the input slots. The calculator then multiplies every input by the same factor, so you don't have to edit each ingredient by hand.
Why does my calculation show the wrong amount of an ingredient?
The most common cause is a recipe in the chain that hasn't been set, so the calculator treats that item as a base material instead of breaking it down further. Check that every intermediate item has its own recipe entered.
Does the calculator know about modded recipes and machines?
It works with whatever recipes your recipe viewer can show, so modded crafting recipes generally import fine. Recipes that aren't in the viewer's recipe list — like some machine or multiblock processes — may need to be entered manually.

The calculator keeps your current grid while the item is in your inventory, so you can close the screen and reopen it without losing the setup. If you need to keep a plan long-term, note the final numbers down, since there's no separate saved-project list.
Does the calculator cause lag or affect performance?
No — it's a client-side planning tool that only does arithmetic when you open it, so it doesn't run anything in the background. Any lag you see while using it is almost always from the recipe viewer loading recipes, not the calculator itself.
