BufeticoIn 2023 Tesla reported net income attributable to its shareholders of $14,997 million, the highest in its history. On the same statement, its operating income fell from $13,656 million to $8,891 million, down 35 percent.
Most people read an income statement from the bottom. They find net income, compare it with last year and stop there. Read that way, 2023 was Tesla’s best year. Yet the business earned less that year, and the statement shows it several lines above net income.
Read it from the top down instead, and at every line ask what changed from the line above.
Tesla’s 2023, from revenue down
Revenue was $96,773 million. That is everything Tesla recorded as sales in the year: cars, leasing, regulatory credits other carmakers paid for, batteries, solar and services.
Cost of revenues was $79,113 million, the cost of making and delivering all of that. At Tesla it includes materials, labor, factory overhead, shipping, and the depreciation of tooling and machinery, which is the share of their cost charged to each year. What remains is gross profit, $17,660 million, or 18.2 percent of revenue. That percentage is the gross margin.
Operating expenses come next: $3,969 million for research and development and $4,800 million for selling, general and administrative costs. Operating income, $8,891 million, is what the business earned from running itself before interest and taxes.
Below that line sits money that has little to do with cars. Tesla earned $1,066 million of interest on its cash and investments, was charged $156 million of interest on its debt and booked $172 million of other income, which brings income before taxes to $9,973 million.
Then comes the tax line, which usually takes money away. In 2023 it added $5,001 million, and net income came to $14,974 million. Outside partners in some subsidiaries absorbed a $23 million loss, so the profit belonging to Tesla’s shareholders was a little higher: $14,997 million, the figure that gets quoted.
Where the record came from
A tax line normally shows what a company owes. Tesla’s 2023 line also carries a change in judgment. Over the years it had built up tax losses and credits that could lower future tax bills, and it had kept most of their value off its books because it doubted it would ever earn enough to use them. In 2023 it decided it would. Tesla calls the result “a one-time non-cash tax benefit of $5.93 billion,” and without it the tax line would have taken money away like any other year.
Remove it and net income to shareholders is about $9.07 billion, less than the $12,556 million of 2022. The net margin, final profit per dollar of revenue, goes from 15.5 percent to 9.4. Cash from operations, the cash the business brought in, fell from $14,724 million in 2022 to $13,256 million. I took Tesla’s margins apart in what its gross margin hides.
Two growth figures for the same sales
Inditex, the owner of Zara, reported net sales of €19,755 million for the six months ended July 31, 2026, against €18,357 million a year earlier, growth of 7.6 percent. The same release said sales grew 9.2 percent in constant currency, meaning what growth would have been if exchange rates had stood still.
The 7.6 comes straight from the income statement, and the 9.2 is a recalculation under a definition Inditex writes itself, in a note to its annual accounts. That is a standard disclosure, and a useful one. The distance between them, 1.6 percentage points, is what currencies did to those six months, and I went through that gap in how much of Inditex’s growth is currency.
Where this breaks
Put these lines side by side for many companies and the first problem is that the same line does not hold the same costs. Tesla’s gross profit comes after the depreciation of its machinery. Inditex books all €1,670 million of its amortization and depreciation on a separate line further down, so its gross margin of 58.7 percent carries none of it. In a table the two margins appear side by side as if they measured the same thing.
Growth has the same problem at scale. Not every company publishes a constant-currency figure, and those that do each build it their own way. The only growth figure that exists for every company is the reported one, currency included. Over many years that is also the fairer one, because sales earned in a currency that keeps weakening really do arrive smaller.
A table also cannot read a tax note. Once Tesla’s $5.93 billion lands in net income, it looks exactly like profit from building cars. It is one reason the method I built starts from cash. In the cash flow statement the benefit is subtracted back out, and it never reaches cash from operations.
My own adjustment above has a flaw too. Tesla says the benefit relates to tax assets it expects to use in future years, and if it earns enough to use them, they will lower real tax bills. Leaving it in counts savings from future years as 2023 profit, and taking it out treats them as worth nothing.
Tesla’s record was printed on the bottom line, three lines below the line that made it.
