Implied Tesla average COGs for a $35k base car:
This is from my reconciliation of Tesla's quarterly accounts and using options mix surveys and other bottom up cost estimates and modelling.
- 1Q18 $67.6k ($53.2k ex depreciation).
- 2Q $49.0k ($42.3k ex depreciation).
- 3Q $39.5k ($36.8k ex depreciation).
- 4Q $38.5k ($36.0k ex depreciation) despite c.$1k higher costs from Trump's tariffs.
Elon disclosed a base model 3 production cost of $38k in November. I presume this is on an accounting basis (which is how Elon normally talks about margin guidance), but it is possible Elon’s number includes deferred costs (in which case cost would be $36k on my basis) and also possible it doesn’t include warranty (in which case it would be $40.1k on my basis).
I think Tesla likely finished Q4 with the base cost at $37-37.5k.
Much of the easy work on cost reduction was done in 2018, but there is still room for significant cost reduction in 2019.
Roughly I think further base model 3 COGS savings could be achieved by:
Aside from improving gross margin, Tesla can alternatively try to reduce costs by cutting SG&A. This is the reason for cutting store sales. I roughly estimate this could cut annual SG&A costs by c.$750m, or c.$1.5k per car at annual production of 500k.
- Production ramp from 5k/week to 7/k week, which could reduce depreciation by c.$0.5k per car and staff costs by c.$1.5-2k per car through operating leverage.
- New more efficient battery module and pack designs: $0.5-1.5k per car
- $10-20/kwh reduction in Panasonic cell purchase cost: $0.5-1k per car
- Cancellation of referral program (I'm not sure how this is accounted for, but it may reduce deferred revenue by c.$0.5k)
- Cancellation of Trump's China tariffs: $0.5-1k per car.
- Other supplier cost savings with negotiations and purchasing scale: $0.5-1k
- Other car design improvements: $0.5-1k
- Better production quality to reduce scrap, rework and warranty costs: $0.5-1k
So Tesla needed to reduce COGs $7-7.5k to get base model 3 costs to the target $30k or a 14.3% gross margin on the base model (likely corresponding to 25% or so average across all options). If they are now instead reducing SG&A by $1.5k per car, the COGs cost target can increase $1.5k to $31.5k while maintaining the previous operating margin target.
That leaves $5.5k to $6k COGs reduction needed from the 2018 exit rate to get to the initial targeted operating margins. I've listed measures above that i think could potentially reduce COGs $5.5k to $9.5k. Of these, i think the ramp to 7k/week, new module lines and referral cut have already likely been implemented (together $3k to $4.5k COGs savings).
So if Tesla has ramped to 7k week, i think current COGs are likely $32.5k to $34.5k. This makes current gross margins on the base model 1% to 7% per car (I would guess closer to 1% than 7%). I think Tesla should get this base gross margin to c.10% in the US with the average Model 3 margins at 20-25% this year. In China next year base margin should be higher which should increase group overall model 3 margins.
These numbers are all rough but I'll finish a full model with all of the new options pricing and my estimated options mix in the next week or so.
I don't have any major problems with this analysis. However, we are of course hand-waving and taking WAGs at the cost savings on those various line items and I think your ranges tend towards highly optimistic. In particular I don't think $1.5k to $2k further savings on labor for production is very likely if you consider how many hours labor that represents and the amount of time they've already had to refine the process. Nor do I think it's likely that a new module design would come anywhere close to $1.5k which is a massive percentage of the entire price of the module.
At the end of the day of course it matters less where the exact cost of the base model is and more what the long-term demand is for cars in the upper price ranges since the vast vast majority of profit will come from ~45k$+ up configurations. Or one could alternately argue that the only thing that matters is the competitive advantages/disadvantages since pricing is mostly limited by competition. I appreciate the commentary at any rate.
