For most industries involved in electronics, the rule-of-thumb is the MSRP is five times the cost of goods. The breakdown goes something like -
10% labor
17% to 20% material
Is the Cost of Goods. To that we add -
10% R&D
12% Administrative and Marketing (sometimes a lot more)
10% Warranty costs
??% Margin (aka profit) could run from 1% to 40% depending on the industry. Typically is around 33%.
From there, we sell to the distributors and retailers. Who typically add 10% to 33% on top of their costs.
So it roughly breaks down to - MSRP/5 = Mfg. cost.
So if an espresso machine retails for $500, then the cost of goods (out the Mfg. door) will have to be no more than $100.
Breaking this down further, the typical assembler on the Mfg. floor is going to make $8 to $15/hr plus benefits. The technician and QA folks are going to be making 10$ to 20$/hr. Then you have supervisors, Mfg. Engineers, and Process Engineers, who you have to pay even more.
If you look at most Consumer/Pro-sumer espresso machines, it's easy to see how they are "designed for assembly". A Silvia can probably be assembled - bare chassis, minus the skins, to be functional in about 20 minutes. A Quickmill Andreja shouldn't take more than 30 minutes to assemble to a functional state where they can be burned in and verified functional.
Of course one needs several assembly stations - subassemblies get put together on multi-purpose workstations by batches - wiring harness', boiler assemblies, group head assemblies, etc. Then, there's tracking parts inventories, ordering, stocking packing material, final assembly - put the skins on, final check out, boiler drain, final wipe down, packing, scheduling shipping, and actual shipping.
Plus, something always goes wrong - parts suppliers run out, sometimes tolerances go to extremes, bad lots arrive, etc.
Then, no matter how hard you try, nor how sophisticated the MRP system, nor how great the process control is, at the end of the quarter it's always a scramble resulting in overtime.
So to cover costs, one needs a high volume. Or one needs many common parts to create variations on a machine - i.e. re-using the E61 head on a dual boiler machine. And common parts is key. Adding a part means adding a part number, adding a part number means updating inventory control systems, additional logistics costs because now additional spares inventories need to be updated. In the end adding a $5 part may cost a company $50 or in a large company $5K.
