RandoziCable Cut List Calculator
Write one length per line, with a quantity if you need several, add the allowance you keep for connectors or slack, and get the total length to buy plus the cut list with each piece’s subtotal.

- Enter the allowance added to every piece (0 for none).
- Read the total, the number of pieces and the longest piece.
- Copy the summary or the cut list for your supplier or your shopping list.

Questions
- How is the total calculated?
- Total = sum of quantity × (length + allowance) for every line. Three cables of 2 m with 0.5 m allowance each count 3 × 2.5 = 7.5 m.
- What does the allowance cover?
- Whatever you decide: stripping the ends, connectors, a service loop. It is added once to every piece, not once per line.
- Which line formats are accepted?
- A length (2 or 2.5, a comma works as the decimal mark) or a length and a whole quantity separated by x, × or *. Empty lines are ignored; a negative value, a zero length or a line that is not a number is refused with its line number. Up to 500 lines. Note that 1,000 is read as 1 (a comma is a decimal mark here), so type 1000 without a comma.
- Does it account for cut waste on a reel?
- No: it adds what you list. The remaining length of a reel is not tracked.
