Saved batches are checked against practical project recipes and ranked by how much they can cover without another purchase.

LEFTOVER INVENTORY
What can you make with what you have?
Save material batches on this device. Leftover ranks project ideas by what those exact pieces can cover, then loads the best match into a calculator.

THE LEFTOVER DIFFERENCE
Most calculators start with what to buy. Leftover starts with what you already own.
The workflow now runs in both directions: saved material can suggest projects, and finished project plans can feed usable remnants back into your local inventory.
Carry calculated remnants into the next project and replace a used saved batch with its estimated remainder inventory.
Compare edge starts, centered layouts, rotation and supported stagger options before committing to a layout.
Compare manual package prices, print QR garage labels, and use Workshop Mode for step-by-step cutting guidance.
FROM LEFTOVERS TO FINISHED
See the project, not just the math.
Leftover is designed around a simple homeowner question: “Can I finish this with what I already have?” The answer should feel visual, practical and easy to act on.

Start with a real project.
Leftover answers the question before the store run.
Does Leftover guarantee every scrap will fit?
No. The calculator is a planning check. Total usable material can be sufficient while a particular scrap is the wrong shape for a required cut. Verify the real layout before cutting.
Why include a planning reserve?
Projects commonly lose usable material to cuts, defects, breakage, pattern matching and installation constraints. The reserve gives you a more realistic first estimate.
Are my measurements uploaded?
No. The current calculators run in your browser and do not require an account or photo upload.
What should I count as a usable leftover?
Only count material you would actually install: correct type and dimensions, undamaged, and large enough for a realistic project cut.

Most calculators begin by asking how much you need to buy. Leftover begins with what you already own.
