Budget Size Drives Growth 8x More Than ROI, Research Shows

A story about a rock star might not seem like the obvious starting point for a marketing strategy conversation. But a quote about Morrissey recently made the rounds at the Festival of Marketing that stopped people in their tracks.

Factory Records founder Tony Wilson once observed that Morrissey, "even when he was nobody," behaved like a big rock star from the very beginning. He almost willed himself into becoming one. The mindset came first. The fame followed.

It turns out that principle applies directly to how brands grow.

The Finding That Challenges How Most Marketers Think

At the Festival of Marketing, effectiveness expert Les Binet made a provocative claim. His research found that budget size is roughly eight times more important than ROI in driving growth.

That's a number most marketing teams are not set up to hear. The industry has spent years training itself to chase efficiency, to optimize campaigns, to report on ROI as the gold standard of marketing value. Binet's argument cuts against all of that.

His point is not that ROI is meaningless. It's that effectiveness (actual profit) beats efficiency (better ratios) every time. Budget scale is simply more in marketers' control, and varies far more between brands, than ROI ever does.

The practical implication is uncomfortable. If you want to move the needle on market share, you have to shout loud enough for the whole market to hear you. A handful of likes on a social post, however viral it feels internally, doesn't do that.

Acting Bigger Doesn't Always Mean Spending More

Here's where the conversation at the Festival of Marketing took an interesting turn. The author of a complementary framework called "Building big from lots of littles" joined Binet on stage. The expected showdown between big-budget thinking and scrappy, fragmented approaches never happened.

Instead, both sides landed on the same conclusion: the real enemy is small thinking.

Too many brands, whether large or small, are limiting themselves by acting small. They rely too heavily on tactics that don't scale, such as organic reach, virality, and hard-to-measure activity. They do "more with less" without ever making the case that they need more. They adopt the behaviors of a smaller brand when they shouldn't, or they've become resigned to constraints that haven't actually been tested.

As Binet put it at the IPA Effectiveness Conference 2025, "We're all focused on ROI and we are all trying to do more with less, and the result is that small thinking actually reduces effectiveness, and reduces sales, reduces profit."

"Acting a few sizes bigger than you are" is the phrase that captures the fix. It's a mindset shift as much as a budget shift. It means having the confidence to argue for more resources, to reach more future buyers than you did last year, and to stop accepting a ceiling that nobody actually put there.

The Multiplier Effect of Doing It Consistently

Modern brand-building is not about a single big campaign. Achieving scale today means using more channels and formats than before. But there's a condition: the creative must not be fragmented.

The "lots of littles" framework argues for a "system of ideas" approach. Content should feel native to each platform, but connected by distinctive brand assets that weave everything together. Multiple channels, used consistently, don't just add reach. They multiply it. Combined benefits kick in when the creative is coherent and always on.

The trap is running big bursts of activity with long gaps. Brand memories decay faster than most marketers expect. Topping up memory continuously is more efficient than rebuilding it from scratch after a long silence.

Virality still has a role, but a limited one. If something breaks through organically, it can signal that an idea has potential. But virality alone is not a scalable strategy. The real return comes from backing that idea with paid support and consistent effort over time.

The Ambition to Be 'One of Those Brands'

There's a feeling that people who work in marketing recognize immediately, even if it's hard to describe precisely. Customers sense it too. It's the restless energy of a brand on its way up.

A client brief that came in more than a decade ago captures it perfectly. A marketing leader from a large financial services firm walked into a briefing and said she wanted the next year's campaigns to help them "become one of those brands." No one needed clarification. Everyone in the room knew what she meant: Nike, Apple, Guinness. Brands with a creative, infectious, forward-moving energy that makes people want to be associated with them.

The Super Bowl is one arena where this kind of brand ambition shows up loudly. This year, AI companies like Claude used it to signal momentum to customers and investors alike. The mistake many brands make is treating it as a one-off. The ones who win at this game find ways to connect the high-profile moment to everything else they do, extending it through other channels, building on it over time. Coherence and consistency turn a one-time signal into a sustained reputation.

Posh Spice had the same instinct. Not satisfied with being a pop star, she looked beyond her category from the start. Just like Morrissey before her, the ambition to be a household name came before anyone else believed it was possible.

That's the real takeaway for marketing leaders under budget pressure. The size you act is a choice. Budget constraints are real, but they're not the only variable. The brands that grow beyond their means don't do it by outspending rivals. They do it by refusing to think like the smaller brand they are today, and instead moving with the confidence of the brand they intend to become.
