The Best BCG Waterfall Charts: Design Principles From 200+ Slides

BCG's signature green

The most immediately obvious BCG difference is color. Where McKinsey defaults to navy and mid-blue, BCG leans into green for positive contributions — a distinctive forest or emerald green that's become associated with the firm's visual identity. The red for negative bars tends to be a true primary red rather than a muted brick.

This higher-contrast palette makes BCG charts feel bolder and more legible at a distance — useful in large room presentations. The tradeoff is that it can feel more aggressive in a one-on-one document review. McKinsey's more muted palette reads as more analytical and less assertive.

When to borrow it: if your chart will be projected on a large screen or viewed across a conference table, higher-contrast colors improve legibility. If it's primarily read on paper or screen, the subdued McKinsey palette may feel more appropriate.

Cleaner axes, less chart furniture

BCG tends to use even less axis furniture than McKinsey. In many BCG waterfall charts, the y-axis is entirely absent — there are no tick marks, no axis line, no grid lines. The only quantitative information comes from labels directly on the bars.

This is a confident design choice. It works when the chart is primarily about the relative size and direction of contributors rather than precise absolute values. When you need the reader to compare values to an external benchmark or track against a target, an axis becomes necessary. But in a pure "here's what drove the change" bridge chart, axes are often just noise.

Removing the axis also eliminates the awkward decision of where to set the axis minimum — a common source of unintentional visual distortion in charts with only positive values.

More generous use of subtotals

BCG is more likely than McKinsey to break a complex waterfall into sections using subtotal bars. A revenue-to-profit walk might show a "Gross Profit" subtotal partway through, then continue with operating expenses before arriving at EBIT.

This is good practice when a waterfall has more than 6-7 bars. Without subtotals, the reader has to mentally track the cumulative position through a long sequence of positive and negative bars — a significant cognitive burden. Subtotals act as checkpoints that reset the reader's position in the walk.

The subtotal bar always runs from zero to its value (like a start or end bar), never floats. In BCG decks, subtotals are typically the same dark color as the start and end bars, which reinforces that they represent a total state rather than a change.

BCG's data-dense layout style

BCG reports are generally more data-dense than McKinsey's. This shows up in waterfall charts as a tendency to fit more bars into a single chart — sometimes 9 or 10 — and to include more detailed callout annotations explaining specific bars.

The risk is crowding. When bars are narrow and labels overlap, the chart becomes harder to read than a table. The discipline is to ask: does each bar represent a genuinely distinct driver that the audience needs to understand separately? If two bars are adjacent, both small, and both pointing the same direction, they can often be combined with a "+" label.

Where BCG uses waterfall charts

BCG's public waterfall charts appear frequently in three domains that reflect the firm's research strengths:

• Sustainability and climate — emissions gap analysis, abatement cost curves decomposed by technology
• Consumer and retail — market growth decomposed by segment, channel, or geography
• Technology and digital — productivity gains or cost reductions broken down by automation lever

The most underrated BCG technique: the "so what" callout

In many BCG waterfall charts, you'll see a callout box or annotation pointing to one specific bar — often the largest contributor — with a sentence explaining its significance. "This single lever accounts for 45% of the total opportunity."

This is excellent practice. The waterfall shows the full decomposition, but the callout directs the reader's attention to what actually matters. Rather than leaving the reader to draw their own conclusions from the shape of the chart, the callout does it for them.

It also creates a natural bridge to the next slide, which typically dives deeper into that specific driver. The waterfall serves as both a summary and a roadmap for the rest of the section.
