Aftermarket Services Margin in Manufacturing: Why Service Profits Beat Equipment Sales by 2 to 10x

Most OEMs are optimizing for the wrong number. Across thirty industries, McKinsey research found that aftermarket services deliver an average EBIT margin of 25 percent, more than double the roughly 10 percent margin on new equipment sales. Syncron’s analysis puts the gap even higher: service margins run at least 2x new product sales and as much as 10x in some cases, with manufacturers often earning 40 to 50 percent of total profit from service while equipment sales barely break even. If your growth strategy still starts and ends with units sold, you are chasing the lower margin half of your own business while the higher margin half sits underpriced, under-resourced, and treated as a cost center. This is not a call to abandon equipment sales. It is a case for understanding your aftermarket services margin as clearly as manufacturing companies track equipment margin today, and building a real strategy around it.

The problem: service is a courtesy, not a P&L line

At most small and mid-sized OEMs, service exists to support the equipment sale, not to stand on its own as a business. A customer buys a machine, gets a warranty, maybe signs up for a basic maintenance plan, and the relationship from there is reactive: a call comes in, a technician gets dispatched, a part gets shipped. Nobody is asking whether that maintenance plan is priced to reflect the value it delivers, or whether the spare parts catalog is priced at all, or whether the company even knows what percentage of its revenue and profit comes from service versus new equipment. 

This is not a small oversight. It means the highest margin part of the business is being run without the pricing discipline, systems, or executive attention that the lower margin part gets. A CEO who tracks equipment backlog weekly may not be able to say, without pulling a report from three systems, what the company’s aftermarket attach rate is. Before getting to the fix, it is worth sitting with the size of the number. 

The data: the margin gap is not marginal

The 25 percent versus 10 percent figure is the headline, but the supporting detail from McKinsey’s research is where the opportunity gets concrete. A few findings stand out. 

Parts, not labor, drive the margin. Spare parts sales typically generate gross margins exceeding 30 percent, while maintenance labor averages closer to 10 percent. If your service organization is built primarily around dispatching technicians rather than managing a parts and consumables business, you are running the lower margin half of an already higher margin category. This is especially visible in industries like trucking and agriculture, where equipment downtime has an immediate cost to the customer, and a parts stockout does not just cost a sale, it damages the relationship and puts a service contract at risk. 

Pricing is systematically too low. Across ten industries studied, OEMs were able to improve EBIT margins by 3 to 10 percent simply by re-pricing, particularly for long-tail parts serving older equipment still in the field, where demand is steady and price sensitivity is lower than most companies assume. One industrial machinery company improved EBIT margin by 2 full percentage points within a single year just by re-pricing 100,000 spare parts SKUs. That is not a new product line or a new market, it is correcting a pricing error that had likely existed for years. 

Strategic focus compounds. A power equipment manufacturer that bundled its service offerings saw a 20 percent increase in aftermarket revenue and 30 percent growth in long-term contract penetration. A construction equipment company that repositioned its service business realized 20 percent annual EBIT growth from services alone. These are not hypothetical upsides, they are documented outcomes from companies that treated service as a business unit rather than a support function. 

Put together, the pattern is consistent: the money is already there, inside your existing installed base and your existing customer relationships. It is being left on the table through underpricing, under-management, and a lack of strategic attention, not through any lack of demand. 

The framework: two ways to run the same company

The clearest way to see the gap is to compare how a company operates when it is structured around equipment sales versus when it is structured around service. 

 

Equipment-first economics 

Service-first economics 

Margin profile 

~10% EBIT, thin and cyclical 

~25% EBIT, higher and steadier 

Revenue predictability 

Lumpy, tied to capital spending cycles 

Recurring, tied to installed base 

Pricing discipline 

Competitive, transactional 

Value-based, relationship-driven 

Customer relationship 

Ends at delivery, restarts at next purchase 

Continuous, deepens over the equipment lifecycle 

What gets measured 

Backlog, units shipped, win rate 

Attach rate, contract renewal, parts margin 

Systems in place 

Standard ERP, order-to-cash 

Contract management, scheduling, inventory tied to service obligations 

 

Most OEMs in the $0 to $100M range are somewhere in the left column by default, not by design. Nobody sat down and decided service should be an afterthought, it simply grew that way because the sales organization, the systems, and the incentives were all built around moving equipment. Shifting even partway toward the right column does not require abandoning equipment sales, it requires treating service as a business with its own targets, pricing, and systems, the same rigor already applied to equipment. 

It is worth being honest about what stands in the way. Standard ERP systems are typically built for product transactions, not for managing contract obligations, scheduling, and inventory the way a service business requires, which is part of why so many OEMs get stuck offering ad hoc service rather than a structured, contract-based program. The same research found that 62 percent of manufacturers running planned maintenance contracts already consider that service profitable, which suggests the model works once a company commits to it, the barrier is usually operational readiness, not market demand.

So What: this is a margin decision, not a service decision

The business case here is not about customer experience or being a more complete solutions provider, though both are true side effects. It is a margin decision. A company earning 10 percent EBIT on equipment and treating service as a break-even support function is leaving a 25 percent margin business half built. For a $50M OEM, even a modest shift in aftermarket attach rate and pricing discipline can move the needle on overall company profitability more than a comparable amount of new equipment growth, without the capital investment or the sales cycle that new equipment growth typically requires. 

The harder part is rarely conviction, most operators already sense service is undervalued. The harder part is knowing exactly where the gap is: which parts are underpriced, what the real attach rate is, which systems are holding the shift back. That is where Servitize IQ comes in, giving OEMs a structured way to assess where their service business actually stands today (pricing, attach rate, systems, contract mix), benchmark that against peers in the 25 percent margin range, and build a practical roadmap to close the gap without disrupting the equipment business that still pays the bills today. 

If you do not currently know your aftermarket attach rate, your service EBIT margin, or what percentage of your spare parts catalog has not been re-priced in the last two years, that is itself useful information. It means the 25 percent margin business referenced above is sitting inside your company right now, waiting for someone to manage it as deliberately as the equipment side already is managed. 

Next step: if you want a clear read on where your service business stands against the benchmarks above, a Servitize IQ readiness conversation is a low lift way to find out, no commitment beyond an honest look at the numbers.
