Every marketing budget eventually forces a choice. Spend on campaigns that build the brand over time, or spend on tactics that drive immediate sales. Most organizations treat this as a tension to manage through intuition or politics. Les Binet and Peter Field treated it as a question that data could answer.
Their research, drawn from hundreds of award-winning campaigns in the IPA Databank, produced a finding that has shaped marketing strategy for over a decade: consumer brands that allocate roughly 60% of their budget to brand building and 40% to activation tend to produce stronger long-term business outcomes than those that tilt heavily in either direction.
What Is the 60/40 Rule?
The 60/40 rule states that consumer brands achieve optimal long-term growth when they allocate approximately 60% of their marketing budget to brand building and 40% to sales activation. This ratio emerged from analysis of the IPA Databank conducted by Les Binet and Peter Field, first published in their 2013 report The Long and the Short of It.
Brand building refers to broad-reach, emotionally resonant campaigns designed to increase mental availability and build memory structures over time. Activation refers to targeted, often rational or promotional tactics meant to trigger immediate purchase decisions. Both serve necessary functions, but they operate on different timescales and produce different kinds of effects.
Campaigns that allocated budget near the 60/40 split outperformed those that tilted heavily toward either end. The effect showed up not just in short-term sales, but in sustained increases in market share, profit margins, and pricing power. The research suggested that brands which over-invest in activation at the expense of brand building eventually deplete their equity and face diminishing returns.
Key takeaway: The 60/40 rule is not a universal formula. It is an empirical finding that the optimal balance for most consumer brands favors long-term brand investment while maintaining sufficient activation to harvest demand.
Who Are Binet and Field?
Les Binet and Peter Field are marketing effectiveness researchers whose partnership combined quantitative rigor with strategic insight. Their work has become a reference point for how marketers think about balancing long-term and short-term investment.
Les Binet served as Head of Effectiveness at adam&eveDDB. His background includes training in physics and artificial intelligence, and he specializes in econometric modeling. Binet approaches advertising as a system that can be measured, modeled, and optimized through data rather than intuition alone.
Peter Field built his career as a strategic planner and consultant. He spent decades interpreting consumer insight and helping brands articulate positioning. Where Binet brought statistical analysis, Field brought experience translating research into strategic guidance that practitioners could apply.
Their collaboration produced a body of work that includes The Long and the Short of It (2013), Media in Focus (2017), and Effectiveness in Context (2018). Each study refined their core findings and extended them to new contexts, including digital media and business-to-business marketing.

What Is the IPA Databank?
The IPA Databank is a collection of detailed case studies submitted to the Institute of Practitioners in Advertising effectiveness awards. Each entry documents campaign objectives, budgets, tactics, and measurable business outcomes. The database has accumulated hundreds of cases over decades, creating a large dataset for analyzing what drives advertising effectiveness.
Binet and Field used statistical methods to identify patterns across this dataset. By coding each case for variables like budget split, media channels, creative approach, and business results, they could test which factors correlated with stronger outcomes. The scale of the database allowed them to surface patterns that would be invisible in individual case studies.
The IPA Databank has limitations. Its cases are award submissions, which tend to be stronger than average campaigns. The database reflects campaigns that organizations chose to enter and document, which introduces selection effects. Results from award-winning campaigns may not generalize perfectly to typical marketing efforts.
Despite these limitations, the database remains one of the most comprehensive sources of documented advertising effectiveness. Its longitudinal nature allows researchers to track how effectiveness patterns change over time as media landscapes and consumer behavior evolve.
Key takeaway: The IPA Databank provided the empirical foundation for Binet and Field’s research. Its scale enabled pattern detection, though its award-focused nature means findings may not apply uniformly to all campaigns.
How Do Brand Building and Activation Differ?
Brand building and activation serve different functions in a marketing system. Brand building expands future demand by creating memory structures and positive associations. Activation converts existing demand into immediate sales. Both are necessary, but they operate through different mechanisms and on different timescales.
Brand building typically involves broad reach, emotional messaging, and creative execution designed to be memorable. Its effects accumulate slowly but persist over time. A brand-building campaign may not produce measurable sales lift in the first quarter, but it builds the mental availability that makes future activation more effective. Brand building increases the pool of people who will consider the brand when a purchase occasion arises.
Activation typically involves targeted reach, rational or promotional messaging, and calls to action designed to trigger purchase. Its effects appear quickly but decay rapidly. An activation campaign produces immediate sales lift, but once the campaign ends, the effect fades. Activation harvests the demand that brand building has created.
The relationship between these functions matters for budget allocation. Brands that over-invest in activation eventually face diminishing returns because they deplete their reservoir of potential buyers without replenishing it. Brands that over-invest in brand building may build strong mental availability but fail to capture demand when purchase occasions arise.
Common failure mode: Treating brand building and activation as separate silos managed by different teams with different incentives. When the brand team optimizes for awareness while the performance team optimizes for conversions, the overall system loses coherence.
Key takeaway: Brand building and activation are complementary, not competing. Brand building expands future demand; activation converts present demand. Sustainable growth requires both.
Why Does the Optimal Ratio Vary by Category?
The 60/40 split emerged as an average optimal ratio across consumer brands, but Binet and Field consistently emphasized that context shapes the ideal allocation. Purchase cycle length, category dynamics, brand maturity, and competitive intensity all influence where the balance should fall.
Categories with short purchase cycles, where consumers buy frequently and decisions happen quickly, may lean more heavily toward activation. The opportunity to influence immediate purchase is higher, and the window for brand building to affect any single decision is narrower. Fast-moving consumer goods brands often operate closer to 60/40 or even 55/45.
Categories with long purchase cycles, where purchases happen rarely and involve extended consideration, may benefit from higher brand-building investment. Mental availability built over years influences the consideration set when a purchase occasion finally arrives. Automotive, financial services, and luxury brands often allocate more heavily toward brand building.
Business-to-business marketing presents different dynamics. Binet and Field’s research with LinkedIn suggested that B2B brands often benefit from allocations closer to 50/50, reflecting longer sales cycles, multiple decision-makers, and the role of rational evaluation in business purchasing.
Brand maturity also matters. New brands may need higher activation investment to establish initial trial and distribution. Established brands with strong mental availability may sustain periods of higher brand-building investment. Declining brands may need to rebalance toward brand building to arrest erosion.
Key takeaway: The 60/40 ratio is a useful starting point, not a universal prescription. Optimal allocation depends on category, brand maturity, competitive context, and purchase dynamics.
What Did the Research Actually Demonstrate?
The research demonstrated that marketing budgets skewed toward brand building produced stronger long-term business outcomes than budgets skewed toward activation. This finding held across multiple studies, time periods, and category contexts, suggesting a robust structural pattern rather than a statistical artifact.
Specifically, the research showed that campaigns with majority brand-building investment produced larger effects on market share, profit margins, and pricing power when measured over multiple years. Activation-heavy campaigns produced stronger short-term sales effects but weaker long-term growth. The most effective campaigns balanced both functions.
The research also showed that the proportion of budgets allocated to activation had increased over time, particularly with the growth of digital performance marketing. Binet and Field argued that this shift toward short-termism was eroding brand equity and producing diminishing returns at the aggregate level.
Several mechanisms explain these patterns. Brand building creates memory structures that persist and compound over time. Each exposure reinforces the last, building cumulative mental availability. Activation effects are transient. Each campaign must start from baseline rather than building on previous investment. Over time, brand-building investment creates compounding returns while activation investment produces linear or diminishing returns.
The research does not demonstrate that the 60/40 ratio is optimal for every brand in every situation. It demonstrates that, on average across the IPA Databank, allocations near this ratio correlated with stronger long-term outcomes than allocations far from it.
Key takeaway: The research provides evidence that long-term brand investment produces compounding returns that short-term activation cannot replicate. The 60/40 ratio represents an empirical average, not a proven optimum for all contexts.
What Are the Limits of This Research?
The 60/40 rule emerged from a specific dataset with specific characteristics. Understanding its limits helps practitioners apply it appropriately rather than treating it as a universal law.
The IPA Databank consists of award submissions, which skew toward well-executed campaigns. Brands that enter effectiveness awards tend to have stronger strategies, better creative, and more resources than average. Findings from this population may not generalize fully to typical marketing programs.
The research measures correlation, not causation. Campaigns with 60/40 allocation produced better outcomes, but the analysis cannot fully control for confounding factors. Brands that allocate budgets thoughtfully may also make better creative decisions, select better media partners, and execute more consistently. The budget split may be a marker of overall strategic capability rather than the sole cause of success.
The research predates several significant shifts in the media landscape. Digital platforms, performance marketing infrastructure, and measurement capabilities have evolved substantially since the core findings were established. Binet and Field have updated their analysis over time, but the foundational data comes from an era with different channel mixes and consumer behaviors.
Finally, the 60/40 ratio describes budget allocation, not strategic priority. A brand could allocate budgets correctly but execute poorly on either function. Budget split is necessary but not sufficient for effectiveness.
Common failure mode: Treating the 60/40 ratio as a formula that guarantees results rather than a principle that guides thinking. Budget allocation matters, but it cannot substitute for strategic clarity, creative excellence, or coherent execution.
Key takeaway: The 60/40 rule is a useful heuristic, not a universal law. Its value lies in challenging short-termism and rebalancing attention toward long-term investment, not in providing a precise formula for every situation.
How Should Brands Apply These Principles?
Brands should use Binet and Field’s research as a framework for evaluating balance, not as a formula for calculating allocation. The principles matter more than the specific numbers.
Start by assessing current allocation honestly. Many organizations discover that their actual spend skews more heavily toward activation than they assumed, particularly when digital performance marketing is included. Understanding the baseline reveals whether rebalancing is needed.
Consider category and brand context. Short purchase cycles, new brand launches, and competitive crises may justify temporary activation emphasis. Long purchase cycles, established brands, and stable markets may justify higher brand-building investment. The 60/40 ratio is a reference point for consumer brands in typical conditions, not a target for all situations.
Align measurement with investment horizons. Brand building produces effects that unfold over quarters and years, not weeks. Organizations that measure brand investment on activation timescales will consistently undervalue its contribution and pressure budgets toward short-term tactics. Measurement systems should match the causal timescales of different investment types.
Ensure that brand building and activation reinforce rather than contradict each other. Budget allocation is necessary but not sufficient. If brand campaigns build one set of associations while activation campaigns leverage different appeals, the overall system loses coherence. Both functions should express the same underlying meaning.
Key takeaway: Apply the 60/40 principle as a check against short-termism and a prompt for balance, not as a rigid rule. The goal is sustainable growth through complementary investment, not mathematical precision.
Conclusion
The 60/40 rule offers a corrective to marketing’s drift toward short-termism. It provides empirical grounding for the intuition that brands need long-term investment, not just immediate activation, to sustain growth.
The specific ratio matters less than the underlying principle: brand building and activation serve different functions, operate on different timescales, and produce different kinds of returns. Sustainable growth requires both. Organizations that over-invest in activation deplete their brand equity. Organizations that neglect activation fail to harvest the demand they create.
The question for any brand is not whether to follow the 60/40 split precisely. The question is whether current allocation reflects strategic intent or has drifted toward the measurable and immediate at the expense of the durable. Binet and Field’s research does not provide a formula. It provides a framework for asking better questions about balance, patience, and the systems that govern long-term growth.
