My quick estimate is that the higher salaries might increase total costs by about 2% (when fully ramped up). Compare that to 10% import tariff and probably roughly 3% of shipping costs.I saw a post about salaries in Giga Berlin. Those salaries seemed extremely high for manufacturing jobs, and they didn't even include stock based compensation. I assume the situation is similar in Fremont. We don't know exactly which factory and region is making profits but I started to think that does all/majority of Tesla's profits come from MIC cars - especially MIC exports? Profitability skyrocketed at the same time as Giga Shanghai ramped + it would make sense logically. Right now they are exporting those cheaply made Shanghai cars to Europe and selling them at the same price as Fremont cars.
Risk: what happens when Berlin starts to ramp up and Shanghai exports starts to decrease? Are we going to see crash in profit margins or does shipping costs + import tax make up the difference in employee salaries?
A bigger issue might be parts and materials. China is an excellent place to be in terms of supply chain. According to Tesla's recent impact report Shanghai is now 90% localized while Fremont is about 75% localized. How well can Tesla localize their supply chain in Europe and at what cost? But then again most parts and materials are cheaper to ship and have lower tariffs than full cars.
Then there are capital costs, specifically depreciation costs might be higher in Berlin, but that has probably less than 1% effect on the total cost.
So my guess is that Tesla should be able to achieve lower total costs once Berlin ramps up fully. And that does not yet take into account of the newer technology in Berlin.
