A Sankey diagram is a picture of where money went. Revenue enters on the left as one wide band, then splits and narrows as each cost takes its share, until whatever is left exits on the right as profit - or the band simply ends, if a cost took all of it. The one below is a real sankey.it diagram, not a mockup.
Not every company reports revenue segments broken out finely enough to draw as their own bands - Broadcom Inc.'s Q3 FY2026 statement is one of them. When that detail is not available, the diagram simply starts at Revenue itself: the single wide bar on the left, with nothing feeding into it.
Revenue is the hub of the whole diagram - the one band every dollar passes through before anything is spent. For Broadcom Inc.'s Q3 FY2026, that band is $29.6B. Every narrower band after it is a fraction of this one number.
The first split is the cost of actually producing what was sold. What survives that split is gross profit - Broadcom Inc.'s Q3 FY2026 gross margin is 69.1% of revenue. A wide gap between the revenue band and the gross band means the cost of revenue took a large bite; a narrow gap means most of revenue survived the first cut.
Next, operating expenses - research, sales, and everything else it costs to run the business day to day - take their own share of what gross profit left behind. What is left after that is operating income, the clearest read on whether the core business itself is profitable, before tax and anything outside normal operations.
The final band is net income (or net loss) - what remains after tax and every other cost has taken its share. For Broadcom Inc.'s Q3 FY2026, that is 44.2% of revenue. This is the number a headline usually quotes on its own; the diagram shows the whole path it took to get there.
Not every company reports a profit. sankey.it never flatters a loss into looking smaller than it is: once a cost consumes every dollar left at a stage, the diagram simply stops there - there is no negative band, no borrowed color from the next stage, and no reframing. The real loss figure still sits right beside the diagram, in text, exactly like every other number on the page.
Lucid Group, Inc.'s Q2 FY2026 statement lost money - the cascade above ends where the last dollar of revenue went, and the loss itself is called out in red text rather than a fabricated bar.
