A saw cut can change which stock fits
One 5×60 in area and one 5×36 in area fit in a single 96 in board when kerf is zero. With a measured 1/8 in kerf, 60+36+1/8 exceeds 96: a 36 in remainder no longer exists after the first cut. In this greedy plan two 96 in boards are opened; a separate single 144 in stock scenario uses one board. Fewer boards and less purchased length are different choices.
These are calculated scenarios, not measured customer installations. Inputs and limits follow the calculator method.

Inputs and alternative plans
A 10-inch-wide by 50-inch-long area; actual face 5 in; zero side gap; two full rows; one board per bundle.
| Stock option | Saw kerf (in) | Two cuts fit? | New boards |
|---|---|---|---|
| 100 in stock | 0 | 50+50 = 100: yes | 1 |
| 100 in stock | 1 | 50+1+50 = 101: no | 2 |
| 102 in stock | 1 | 50+1+50+1 = 102: yes | 1 |
What changes the order?
The planner charges a cut when a positive remainder remains, including the second cut from 102-inch stock. Thus the third alternative includes two inches of kerf loss. Compare supported stock lengths separately rather than assuming the longest board always minimizes cost.
Before using this result
The greedy cut plan is not a proof of global optimality. Verify lengths, blade width, end defects and supplier bundle quantities; this model does not create butt joints.
