Before any company I run, chair, or advise spends a dollar on growth, I apply one test: take material margin — revenue minus the direct cost of materials — and divide it by total employee cost. If the answer is around 2.0 or better, the business has earned the right to grow and I will fund almost any sensible initiative it proposes. If the answer is below the line, every growth dollar is frozen until the economics are fixed, because growth poured into a leaking business does not fill the bucket. It widens the hole. That is the whole test. The rest of this post is where it came from, why it works, and what happened to a board that ignored it.
I did not learn this from a textbook. I learned it by watching companies I was responsible for spend real money on growth and get poorer. Across thirty years and a few billion dollars of enterprise value, the pattern never changed: businesses above the line convert growth into profit almost automatically, and businesses below it convert growth into busyness. The ratio is crude on purpose. Crude tests get used. Elegant ones get admired and ignored.
The Company That Taught Me the Ratio
Years ago I took the chair of an industrial products company doing about $180 million. The board deck was a growth story — two new sales regions, a product line extension, a digital channel build, call it $6 million of annual spend against a promised $40 million of new revenue. Enthusiasm was general. Meanwhile the P&L underneath was quietly bleeding: gross margins had drifted down four points over three years, the customer list had doubled while profit stood still, and headcount had grown faster than margin every year of the strategic plan. The company was spending like a winner and leaking like a colander.
I asked one question nobody had asked: for every dollar we pay our people, how many dollars of material margin do they generate? The answer took the finance team two days to produce, which told me something by itself. The number was 1.5. Then I asked what it had been five years earlier, back when the company threw off cash. The answer was 2.2. Nothing about the market had changed that much. The company had simply piled complexity — customers, SKUs, exceptions, headcount — on top of its own economics until the engine could barely pull its own weight. And the plan on the table was to hitch a trailer to it. We killed the growth spend that week. It was not popular. It was correct.
The Formula, in Plain Language
Material margin divided by total employee cost. Material margin is revenue minus the direct cost of the stuff — materials, purchased components, merchandise. Deliberately, it is not gross margin: I strip out direct labor and overhead allocations because I want the numerator clean of accounting judgment. Employee cost is everything you pay everybody: wages, salaries, benefits, bonuses, taxes, contractors doing employee work. No exclusions for the corner office. The ratio asks the simplest question in business: does the value your products create cover the cost of the humans required to create, sell, and administer it — with enough left over to fund everything else?
Everything else is the point. Out of that spread you must pay rent, freight, insurance, interest, capex, and taxes, and still deliver a profit. At 2.0, a dollar of people cost is matched by two dollars of material margin, and the spread reliably covers the rest with room to invest. At 1.5, the spread is consumed by the fixed costs of existing, and there is nothing left for offense. The beauty of the ratio is that it cannot be argued with in the way strategy can. It is arithmetic. I have sat in rooms where executives fought the implications for an hour and never once disputed the number.
Why the Line Sits at 2.0
The threshold is empirical, not theoretical. Across the industrial, distribution, and services companies I have run and reviewed, businesses that sustain roughly 2.0 or better generate cash through cycles, self-fund growth, and command premium multiples at exit. Businesses in the 1.6 to 1.9 band survive but never get ahead — every good year’s surplus disappears into the next year’s complexity. Below 1.5, the company is in slow liquidation whether or not anyone has said so out loud. The line is fuzzy at the edges and varies a bit by model; a distributor and a precision manufacturer wear it differently. What does not vary is the direction of the answer.
People sometimes object that the threshold is unfair to their industry. Occasionally they are right, and we adjust. Far more often the objection is the sound a below-the-line business makes when it meets a mirror. The purpose of a threshold is precisely to end the negotiation. Every company below the line has a story about why it is special. The bank that holds its revolver has heard the story too, and prices it accordingly.
Below the Line: The Fix-First Sequence
When a business fails the test, the answer is not austerity and it is not a hiring freeze dressed up as strategy. The answer is a specific sequence, run in order, that I have used in every turnaround I have touched. It works because each step funds and simplifies the one after it:
Focus. Run the 80/20 analysis on customers and products. The top quartile typically delivers 105 to 150 percent of profit; the tail consumes it. Decide, explicitly, who and what you are for. Everything else in the sequence flows from this decision.
Price. Reprice the tail to its true cost to serve and take targeted increases where your value is proven. Price is the fastest lever in the EBITDA bridge and the most neglected, because it requires courage rather than headcount.
Mix. Shift effort, capacity, and sales attention toward the customers and products the focus step identified. Mix improvement is free margin — same factory, same people, better math.
Complexity. Strip the SKUs, exceptions, special processes, and one-off promises the tail left behind. Complexity is where the ratio quietly went to die, and removing it is how employee cost falls without a single layoff announcement.
Notice what is absent: no new markets, no new products, no transformation program with a lanyard and a logo. The fix-first sequence is subtraction and pricing, which is why it improves the ratio within two or three quarters instead of two or three years. At the $180 million company I described above, eighteen months of this sequence took the ratio from 1.5 to 2.1 — and only then did we relaunch the growth agenda, most of which suddenly cost less and returned more because the business underneath it was clean.
What Earning It Unlocks
Crossing the line changes the character of every decision that follows. Above 2.0, growth investments compound instead of compensate — a new region lands on a cost structure that converts margin into profit, not into subsidy for the tail. Hiring becomes accretive: each added dollar of employee cost has a track record of bringing two dollars of margin with it. Debt capacity expands. Exit multiples improve, because acquirers pay for engines, not for revenue. And the leadership conversation changes from defending spend to allocating surplus, which is a different job done by more cheerful people.
I saw the contrast most vividly running two businesses side by side in the same portfolio. One, a flow-control manufacturer at 2.3, added a two-person applications team and watched a $14 million segment appear over two years — the investment paid back before the annual report mentioned it. The other, a fabricator at 1.7, added a nearly identical team in the same quarter, and the same caliber of people spent two years drowning in expediting calls and quote exceptions for accounts that never should have existed. Same sponsor, same playbook, same year. The only variable that mattered was the base each investment landed on. That is the ratio doing what strategy decks cannot: predicting the outcome before the check is written.
There is a quieter benefit I value more. A company that has earned the right to grow can say yes quickly. When the ratio is healthy, I do not need a committee to evaluate every opportunity, because the base business is not fragile — a mistake costs money instead of costing the company. Speed is a compounding advantage, and speed is downstream of clean economics. Slow companies are not slow because their people are slow. They are slow because every decision has to be litigated against a P&L that cannot absorb error.
The Discipline of Saying No to Good Ideas
The hardest part of this test is that it forces you to reject genuinely good ideas. Not bad ideas — those are easy. Good ones: the adjacency that customers are asking for, the bolt-on at a fair price, the product extension the engineers already half-built. Below the line, the answer to all of them is not yet, and not yet satisfies nobody. I have delivered that answer to founders, to sales leaders, and to my own instincts, and it never gets applause. The idea is good. The timing is wrong. Those two sentences are both true at once, and a CEO who cannot hold both at once will eventually fund the idea and starve the fix.
The wrong-time problem is hardest with founders, and I will name it because I have lived it from the chairman’s seat. A founder’s growth idea is never just an idea — it is identity, and declining it feels to him like a verdict on the whole enterprise. The move that works is to agree on the test before you discuss any specific idea. Get the founder to endorse the ratio and the 2.0 line in the abstract, in a calm quarter, when nothing is on the table. Then when the pet project arrives at 1.7, you are not arguing against his idea; the two of you are standing on the same side of the table looking at his number. It does not make the conversation pleasant. It makes it survivable, and repeatable, which matters more.
My rule is to keep a written parking lot. Every good idea we decline goes on one page with a name next to it, and the page is reviewed the quarter after the ratio crosses 2.0. This does two things. It tells the organization the ideas are deferred, not dead, which keeps people bringing them. And it turns the ratio into a shared finish line instead of my personal veto — the fastest way to fund your project is to help fix the base business. You would be surprised how quickly complexity dies when killing it funds someone’s dream.
The Board That Wanted to Grow at 1.6
Let me tell you about the time the test lost the argument. A sponsor-backed specialty manufacturer, call it $220 million of revenue, ratio of 1.6 and drifting down. I was on the board. The value creation plan called for an aggressive push into an adjacent vertical — new salesforce, new applications engineering, roughly $9 million of spend over two years. I made the case for fix-first: the core was leaking, the 80/20 analysis showed a bottom half of the customer book that consumed a third of operating cost to produce four percent of margin, and the adjacency would land on top of all of it. The rest of the board heard me out, thanked me, and voted for growth. The market window, they said, would not wait. Windows never do, in board decks.
The adjacency actually worked — that is the painful part. New vertical revenue hit plan almost exactly. But it arrived on a cost base that ate it alive: the new customers inherited the same exception-riddled service model, the new SKUs multiplied the complexity the old ones had created, and employee cost grew faster than material margin for eight straight quarters. Three years in, revenue was up nearly 30 percent and EBITDA was down 12. The ratio had sunk to 1.4. The sponsor missed its exit window, the CEO was replaced at month twenty-six — right in the middle of the eighteen-to-twenty-four-month kill zone — and the fix-first program got run anyway, by a new team, at crisis prices. The company earned its right to grow eventually. It just paid twice for the privilege.
How Sponsors Should Use the Ratio
For private equity operating partners, the ratio belongs in two places. First, portfolio reviews: put material margin over employee cost on one page for every company, trended eight quarters, next to the growth capex each is requesting. The pattern will offend some management teams and inform every capital allocation decision you make that day. Companies above the line get their growth funded fast. Companies below it get a fix-first plan and a dated path back to offense. The conversation stops being about whose narrative is better and starts being about arithmetic, which is a considerable upgrade for most portfolio reviews.
Second, diligence. The ratio and its five-year trend tell you more about a target than most of the commissioned studies in the data room. A business at 2.3 and rising is an engine; underwrite growth. A business at 1.6 and falling is a fix-first deal wearing a growth thesis, and it should be priced and planned as one — the first eighteen months belong to focus, price, mix, and complexity, not to the adjacency slide. With multiple expansion dead, the bridge has to be earned inside the P&L, and the ratio tells you on day one which kind of bridge you are actually buying. Deals go wrong at entry far more often than at exit. This is one of the cheapest ways I know to see it coming.
Run the Test This Week
You can compute your ratio in an afternoon with a trial balance and a payroll summary. Material margin over total employee cost, this year and each of the past four. The trend matters as much as the level — a 1.9 climbing from 1.6 is a different company than a 1.9 fallen from 2.4. Put it on one page. Show it to your team before you show them the growth plan, because the ratio decides which conversation you are allowed to have.
Two measurement mistakes to avoid, because I see them constantly. First, do not let anyone substitute gross margin for material margin — direct labor and overhead allocations smuggle judgment into the numerator, and the whole point of the test is that it contains none. Second, resist the urge to exclude anybody from the denominator. The moment the corporate office, the new hires still ramping, or the division being fixed get carved out, the ratio becomes a negotiation, and a negotiated ratio protects exactly the complexity it was built to expose. Take the number raw. If it is ugly, it was ugly before you measured it — you have simply stopped paying for the ignorance.
If you want a second set of eyes, The 80/20 Institute runs a free Business Assessment that computes the ratio, runs the 80/20 concentration analysis underneath it, and tells you plainly whether your next dollar belongs in growth or in the fix. It costs you nothing but honesty. Companies above the line should grow boldly — you have earned it. Companies below it have a different job first, and the sooner it starts, the sooner the growing gets to.
Frequently asked questions
What does it mean to earn the right to grow?
It means passing a simple economic test before spending on growth: material margin (revenue minus direct material cost) divided by total employee cost should be roughly 2.0 or better. Above the line, growth investments compound. Below it, growth dollars land on a leaking cost structure and typically make the business busier and poorer.
How is the right-to-grow ratio calculated?
Divide material margin by total employee cost. Material margin is revenue minus the direct cost of materials and purchased components — deliberately excluding direct labor and overhead allocations. Employee cost includes all wages, salaries, benefits, bonuses, payroll taxes, and contractors doing employee work, with no exclusions.
Why is the threshold set at approximately 2.0?
The threshold is empirical. Across industrial, distribution, and services companies, businesses sustaining roughly 2.0 or better generate cash through cycles, self-fund growth, and command premium exit multiples. Businesses between 1.6 and 1.9 survive without getting ahead, and businesses below 1.5 are in slow liquidation whether or not anyone has said so.
What should a company do if it is below the line?
Run the fix-first sequence in order: focus (80/20 analysis of customers and products), price (reprice the tail to true cost to serve), mix (shift capacity and attention to the profitable core), and complexity (strip the SKUs and exceptions the tail left behind). This sequence typically improves the ratio within two to three quarters without a transformation program.
How should private equity firms use the ratio?
In portfolio reviews, trend the ratio for every company next to its growth capex requests — fund companies above the line and give companies below it a dated fix-first plan. In diligence, the ratio and its five-year trend reveal whether a target is a growth engine or a fix-first deal wearing a growth thesis, which should change both price and the first eighteen months of the plan.
