Why the laser minutes are the smallest part of a coaster set
A per-minute laser price only counts the time the beam is firing. On the example set that is a slice of the 6.6 minutes the set takes. The rest is loading four coasters into the jig, wiping off residue, fitting them in the gift box and closing it.
Then there is the work before the first burn. The example carries 3.25 setup hours: prepping the logo file, the proof the customer approves, a test burn on a blank, building a jig for this coaster, dialing settings and the paperwork. At $63 an hour that is $204.75 of the price, and none of it shows up on a laser timer.
Timing a set from jig to box
Time five full sets, not one. Start the stopwatch when you pick up the first blank and stop when the fifth box is closed, then divide by five. That catches the small waits, the coaster that sits crooked and the box lid that sticks.
Slate, wood, tumblers and acrylic all handle differently, so time each blank type on its own rather than reusing one number. Count the setup separately and only once. If your files usually need fixing, or customers ask for two proofs, put that time in setup. The laser pricing guide shows how the same example prices out step by step.
A reorder with the jig and logo file already done
When the same customer comes back for 50 more sets, the logo file, proof and jig are done. Take 1.5 hours off setup and lower the jig and test box to $10 for test blanks and packing. The order drops to $1,186.78, or $23.74 a set.
The break table under the price shows how quantity moves the original order: $56.07 a set at 10, $33.74 at 25, $26.30 at 50 and $22.58 at 100. Those are the numbers to put in front of a customer deciding between 25 and 50.
What the quick laser estimate doesn't charge for
The $63 break-even rate belongs to the example shop. Yours comes from your space, insurance, software, equipment and billable hours: work it out with the free true hourly rate calculator. The 15% on blanks is a markup, so it is not the same as a 15% margin; markup vs margin explains the gap.
The spreadsheet also charges the CO2 laser by its own hourly cost, puts a markup on outside freight, adds a 5% cushion, keeps a price list of blanks and boxes, prints a customer quote with three quantities and tracks whether each order made money. Its version of the same 50 sets comes to $27.79 a set rather than $26.30.
The $75 minimum stays in place. A quick one-off name on a customer's own item, with no jig or proof, still pays for turning the laser on.
