Start with what you will pay your manufacturer. Stack everything else on top. Get 1 clean number you can fund, plus the 3 numbers that tell you what it means.
The baseline is your winning quote: units times the price per unit, plus the one-time fees on the quote. It is the biggest check most founders write, so everything else is stacked on top of it.
The launch number is every line added together, plus a buffer of at least 10%, then rounded up to a clean number. Whatever the rounding adds goes into the buffer, so the buffer you see is the real one. Never round down: that is asking for less than you need. An exact number like $27,654 looks like a spreadsheet. $30,000 with every line behind it looks like a plan.
Auto rounding picks a step that fits the size of the number:
Break-even divides the launch number by what 1 sale leaves after landed cost and the cost to ship 1 order. On a first run it is often more units than the run itself. That is normal: the one-time costs are paid once, and landed cost drops on run 2.
Runway is the months of monthly costs you set aside. If the buffer goes unused, it buys more months on top.
The presets are the Mauna example from the lesson, with made-up quote numbers. Standard and Overbuilt show the same product with a bigger run, a warehouse, a photo shoot, an agency and a bigger ad budget. What this does not include: your time, and anything after the first run sells.
