Why brand keeps losing the budget argument, and the evidence that wins it

It’s budget season, and I’d like to start with a number that should worry anyone walking into a planning meeting this month.

Only 22% of senior marketers strongly feel they have the data to justify marketing’s value to their CFO. That’s from a Perion and Advertiser Perceptions survey. Turn it around, and nearly four in five of us are heading into the most important meeting of the year without the evidence to win it.

And the pot isn’t growing. Gartner’s 2026 CMO Spend Survey has marketing budgets at 7.8% of company revenue, barely up from 7.7% the year before. A flat pot and a weak case. I think we all know which line gets cut.

I’ve written before about why brand tends to be first in line: performance numbers turn up with a revenue figure attached, and brand turns up with last quarter’s awareness score. This piece is about what that cut actually costs, and why almost nobody in the room can see the bill.

The CFO isn’t the problem

I’ll put the spicy bit up front. When brand budgets get cut, it’s rarely because the CFO doesn’t believe in brand. It’s because marketing brought opinions to a numbers meeting.

The Marketing Society recently asked finance leaders how marketing’s pitch lands with them, and it makes uncomfortable reading. When a marketer says “this is about long-term brand building”, many of them hear “you’ll have to trust us.”

That isn’t a CFO being difficult. That’s a CFO doing the job. “Trust us” is not a line item.

Money moves to whatever can be counted

When brand can’t make its case, the budget drifts toward whatever can. Gartner found awareness and conversion now take 62.6% of media spend, while spending on loyalty and retention has fallen 29% since 2024, to under 15%.

That isn’t because the short term works better. It’s because it’s easier to defend in the boardroom. On a flat budget, the line with a spreadsheet beats the line with a feeling, every time.

The bill for cutting brand arrives after the meeting

What makes a brand cut so tempting is that it costs nothing on the day you make it.

The Ehrenberg-Bass Institute followed 365 US consumer goods brands, across 22 categories, that stopped advertising for a year or more. After twelve months they had lost around 10% of their value market share on average. The decline carried on year after year, and smaller brands fell harder than big ones.

Coming back isn’t one-for-one, either. Analytic Partners, drawing on more than 700 marketing mix models, found that brands which went dark for twelve weeks needed twenty-four weeks to rebuild the momentum they’d lost.

And there’s a third cost that never makes it into the budget paper: your competitors don’t go quiet with you. As I wrote a couple of weeks ago, brands whose share of voice runs ahead of their share of market tend to grow. Pull back, and the brand next to you on the shelf gets a bigger share of voice for exactly the same money. Your cut is their gain.

Put those together if you run a challenger brand. You lose the most when you go quiet, your rivals get louder without spending a cent more, and you have the least room to spend twice as long getting back.

Why nobody connects the cut to the cost

If the evidence is that clear, why does brand keep losing the argument? Because the tools most brands rely on can’t show the damage while it’s happening.

A tracker asks people how they feel, once a quarter, and attitudes are among the last things to move. MMM will tell you what the cut cost, months after the money has gone. And very little in a typical stack is watching what your competitors do in the meantime.

So the bill lands two or three quarters later, as a soft sales line that gets put down to the market, the season or the creative. By then, the meeting where it was decided is long forgotten.

What to bring to the budget meeting

1. Swap belief for a revenue sentence. Not “we need to invest in brand”, but where your momentum stands against the competitive set, and what that’s worth in sales.
2. Model the cut before finance does. Don’t wait for someone to propose trimming brand by 20%. Put the hold-versus-cut scenario on the table yourself, with the going-dark evidence beside it: the share you stand to lose, and how long it takes to win back.
3. Show who benefits if you go quiet. Finance understands share. Name the competitors who’d pick up the voice you give away.
4. Name your assumptions and risks. The finance leaders in that Marketing Society piece said they’re far more comfortable backing investment when marketers are open about risk, rather than presenting plans as sure things.
5. Put a checkpoint in the plan. Agree with finance to read momentum against the competitive set every quarter, not once a year. If brand does get trimmed, you’ll both see the effect while it can still be reversed, not twenty-four weeks too late.

Brand doesn’t need a believer in the finance team. It needs evidence a skeptic would sign off. This budget season, bring that.
