Simply put, a cost advantage is the ability to produce goods and services at lower costs than competition. However, we found there’s much more to it than that. And determining whether it rises to the level of sustainable competitive advantage capable of supporting an economic moat requires a good deal of analysis.

At its core, cost advantage allows a firm to produce goods or services more cheaply than its rivals. But to qualify as a true moat source, that advantage must be structural, meaning it’s deeply embedded in the business and difficult or impossible to replicate. It also tends to be relative. What matters is how a firm’s cost compares to competitors, not the absolute dollar figure. A structural cost advantage can kick off a virtuous cycle.

A firm with lower production costs can offer more competitive prices without sacrificing margins. Those lower prices attract customers, growing market share. Greater volume drives even lower unit costs and higher returns. As scale extends across R&D, distribution, and marketing, the advantage compounds, making it increasingly difficult for competitors to close the gap.

Let’s walk through the key types, importantly, how our analysts actually measure each one. Low-cost resources matter most in extraction industries like oil and gas and mining. The best resources combine lower operating cost and lower development costs. Think Saudi Arabia’s prolific, easy to extract reserves versus the higher cost US versus the higher cost US unconventional shale plays. To measure this advantage, analysts look at a variety of industry-specific metrics, but always with an eye on both operating and capital cost.

Economies of scale and R&D allow large firms to spread massive fixed budgets across more products and customers. In semiconductors, dominant players like ASML, maintain spending levels that small arrivals simply can’t match. The key metrics here are R&D as a percent of sales, new product vitality indices, and crucially whether the spending is actually translating into new revenue growth and successful product introductions.

Advertising and marketing scale enables global firms to spread the cost of high-profile campaigns across vast markets while securing lower rates for media partners.

Our analysts track advertising and marketing spend per user or customer, customer acquisition cost, and market share trends to gauge whether that spending is genuinely cost effective or simply necessary to stay competitive.

Buying power is common in retail and distribution. Large buyers like Walmart or Home Depot extract significant price concessions from suppliers, passing savings to customers or retaining them as margin. The telltale signs are relative gross margins and raw material costs per unit compared to industry benchmarks.

If a large buyer’s input costs aren’t measurably lower than peers, then buying power advantage may be overstated. Manufacturing and processing scale is about volume.

Producing a wide range of similar products at high volume and leveraging integrated distribution like global beverage companies drives costs lower than smaller, less diversified peers.

Here our analysts focus on operating costs per unit, capacity utilization, and operating leverage to distinguish firms with genuine structural scale from those simply running at temporarily high volumes. Route density and proximity reduce transportation costs.

Companies like Cintas and Waste Management maximize deliveries per hour, while commodity producers benefit from locating production close to end markets. Energy consumption per unit delivered, revenue per location, and capacity utilization are metrics that reveal whether transportation cost advantage is real and durable.

Cost advantage moats in our coverage are far and away the most commonly found moat source in financial services, with nearly 60% of the moaty companies that we cover in the industry exhibiting that moat source. That’s the highest mix of any industry in our coverage, followed only distantly by consumer defensive and consumer cyclical.

Within financial services, the two most prevalent drivers of cost advantage are low-cost funding and economies of scope. For banks, the composition of the deposit base, the yield on interest-bearing deposits and credit spreads reveal the true cost of funding. For scope advantages, our analysts tend to look at products or services per client, customer acquisition costs, and whether fixed platform costs are genuinely being fractionalized across a growing revenue base.

This brings us to a real world example, Charles Schwab. Charles Schwab is a textbook illustration of financial services cost advantage mode. By founding its own bank in 2003, and sweeping idle customer cash into its own balance sheet, Schwab built a structurally cheaper funding base that competitors simply can’t replicate. This allows it to generate a comparatively advantageous stream of high margin net interest income. To quantify this, its deposit cost of funding was just 50 basis points in 2025, compared to 185 basis points on average across our banking coverage. The firm also exhibits economies of scope, fractionalizing its product development cost and service costs across an enormous client base with more than $12 trillion in assets on its platform.

The result is an expense on client assets ratio of just 12 basis points in 2025, against 35 basis points for online brokers and 38 basis points for wirehouse competitors, a gap that has widened consistently as the firm grows, underpinning Morningstar’s wide economic moat rating.
