Bridging the Gap

When you look at the full revenue bridge, you’re really seeing a story unfold from left to right. The columns line up like characters in a narrative: base revenue, price increase, price decrease, non‑repeat business effect, repeat business effect, new business effect, mix, currency exchange effect, exception effect, and finally current revenue.

Of course, your bridge might look slightly different. If you only do business in one country, you won’t need the currency exchange effect. If you don’t have much data on repeat or non‑repeat business, those columns may be zero. But the point is the same: the bridge shows the twists, turns, and hidden details that explain how revenue became what it is today.

Revenue Bridge: The Foundation

“Revenue bridges help us understand what’s driving change — by comparing time periods like year‑to‑date or trailing 12 months.” Link to:Revenue Bridge?

That’s the base column — the anchor. Without a consistent comparison, the rest of the story doesn’t hold together.

Price Effect: The Shifts in Value

When prices move up or down, the bridge captures it.

“It’s a bit like Moneyball — small slices of performance that help predict outcomes.” Link to: Nuts and Bolts - Measuring Price Effect 

Each price increase or decrease column is a slice of the game, showing how much uplift or erosion came purely from pricing decisions.

Volume Effect: The Shifts in Quantity

Next comes volume.

“Even small changes in volume — whether gradual or sharp — can be measured using the volume effect.” Link to: The Meat and Potatoes of Volume Effect

This column isolates the impact of selling more or fewer units, independent of price. It’s the clean measure of how quantity alone drives revenue.

Subgroups of Volume: Understanding the Herd

Volume itself breaks down further:

  • Recurring Volume — like owning a cow that produces another cow.
  • New Volume — like buying a cow you didn’t have before.
  • Non‑Recurring Volume — like selling the cow and ending the cycle.

As I wrote earlier:

“Let’s not just count cows — let’s understand the herd.” Link to: Let's Steak Down the Volume Effect

These subgroups tell us where the volume change came from — recurring customers, new customers, or lost business. That’s a deeper story than just “more or less units.”

Mix Effect: What Customers Choose

Beyond volume, mix matters.

“A small shift in product proportions can move revenue and margins more than a small change in volume.” Link to: Mix Mechanics

Even if total units and prices stay the same, the types of products customers buy change profitability. It’s like water levels in a reservoir — the mix shifts year to year, and the impact reveals itself as it happens.

FX Effect: The Tide That Moves the Shore

The FX Effect matters if you operate across currencies.

“Think of FX like the natural tide changes on a coastline.” Link to: The Natural Tide of Currency Change

The tide rises and falls, changing accessibility without altering the beach itself. FX works the same way: it doesn’t change the underlying business, but it changes how revenue shows up in reporting. Isolating FX ensures we don’t misinterpret what’s really happening.

Link to: Exception Effect: “Bank!”

In grade school, my friend and I had a rule: if you banked a shot off the backboard, it didn’t count unless you called “Bank!” first.

That’s exactly how I think about the exception effect in the revenue bridge. It’s the catch‑all bucket for odd, one‑off circumstances that don’t neatly fit into price, volume, mix, or FX. Credits, rebates, incorrect billing — they’re anomalies.

Think of the exception effect as the bloopers reel of the revenue bridge. It’s entertaining to look at, but it’s not the story you want to tell. The goal is to keep exceptions small so the main narrative stays clean and confident.

Closing Thought

With price, volume, volume subgroups, mix, FX, and exceptions all accounted for, the revenue bridge becomes a complete narrative. Each column is a character, each effect a subplot. Together, they tell the full story of how revenue changed — twists, turns, and all.

The full revenue bridge is your Egyptian cubit — a shared language for measuring shifts in price, volume, mix, and FX. With it, you can tell the complete story of how revenue changed, who the characters were, and what role they played.

Intro

     After three years working in pricing—alongside a background in natural resource economics and a master’s in applied econometrics—I’ve come to see pricing as one of the most fascinating areas in business. It’s not just about supply and demand curves or profit maximization. In practice, pricing is messy, nuanced, and deeply human. That complexity is what makes it so compelling. I’ve wanted to document my journey and growth in this field, especially the patterns I’ve observed. As "pricers", we often focus on the exciting parts: choosing between value-based, cost-plus, or competitive models (and interesting variations such as good, better, best). Or speculating on how AI might transform pricing strategy, execution and analytics. But we also dig into the gritty details—the DNA of our systems—where real change happens. Early on, I felt lost. I didn’t know how to measure whether our pricing was working. That’s when I discovered revenue bridges and the power of using them fo...

Assessing Averages

Image
     I really love statistics. They’re all over the place business, economics, the grocery store — average cost per ounce, sale prices, distribution. But here’s the funny thing about some of the averages: the “ASP,” or Average Sale Price, is just that — an average. And if you’re not careful, you can end up averaging the averages. Think about it. Instead of saying, we did half a million dollars in revenue, sold 50,000 units, which equates to $10 per unit , what often happens is someone takes the, say 8 thousand transactions that the revenue happened over — a spread of prices — and averages those transaction-level averages. Suddenly, you’re looking at $9 or $12.50 instead of the true $10. That’s not just sloppy math; it’s misleading. Even weighted ASPs—which I recommend using in pricing—while technically correct, can still hide the real story. Dan Heath talks about this idea of untangling averages in his book “Reset”. His example comes from the military’s attempt to des...

Revenue Bridge?

Image
       Revenue bridges might not be carved from granite — but they’re just as solid when built on comparison. They’re built on the comparison of prices, volume, product mix. We compare constantly — especially in sports. Yankees vs. Dodgers. Jordan or LeBron. Scheffler vs. Tiger (too soon?) In the 1500s, Pope Leo X had a beloved white elephant named Hanno, living in luxury at the Vatican. Then came Ganda — a rhinoceros, the first seen in Europe in over a thousand years. Naturally, the Pope staged a showdown to answer the question of which animal was superior. Ganda charged. Hanno fled. The Pope laughed and after calling the rhino ‘a beast of Satan,’ was shipped off (but sadly didn’t survive the journey). Ganda lived on; however, in Albrecht Dürer’s famous woodcut — armor-plated and horned, despite the artist never seeing a rhino. Hanno remained the Pope's prized animal.  In business, we’re lucky to have more reliable comparisons than an elephant to a rhino. Rev...
