A sign order is mostly the hours before the printer starts
On the example order, design, proofs, cleaning up a logo file, loading the roll and the head clean come to 3.75 hours. At $58 that is $217.50, not far off the $270.67 that all fifty signs take in print and trim time. A square foot price hides that split completely, which is why the calculator asks for the hours and gives you a price per sign at the end.
If the customer sends a clean, print-ready vector file and you cut an hour from the setup box, the sign drops from $25.22 to $23.77. That gap is a fair reason to charge an art fee when the file shows up as a blurry JPEG.
Ten signs at $51.77, 250 at $19.91
The quantity table shows the same yard sign at 10, 50, 100 and 250. Ten come to $51.77 each, fifty to $25.22, a hundred to $21.91 and 250 to $19.91. Past a few hundred the price per sign flattens out, because by then it is mostly coroplast, vinyl and print minutes, not setup.
Use the table for the question every realtor or campaign asks: "what if we order more?" You can answer with real numbers on the phone instead of guessing a discount.
Timing a sign from roll to stake
Minutes per sign covers printing both sides, mounting, trimming and packing for one finished sign. The example uses 5.6 minutes. Time a short run next time: start the clock when you load the first blank and stop it when the last sign is bagged, then divide by the count. A double-sided sign is one sign in this box, not two, so time both passes through the printer.
A minute and a half matters more than it looks. If your printer and trimming bring it down to 4 minutes a sign, the example order drops to $23.29 a sign. If it really takes 7, you were losing that difference on every sign you printed.
Where the full sign shop spreadsheet gets $25.37 a sign
The quick version leaves out each machine's own hourly cost, the separate charge for reprints and botched cuts, the twelve-line list of sign costs owners forget, the customer quote with your proof and size terms, and the job log. With those in, the spreadsheet's version of the same order is $25.37 a sign.
