Marketing ROI: From Budget Fight to Growth Conversation
Marketing ROI Shouldn't Be a Fight
Marketing ROI is hard to measure. So, how do we bring CFO and CMO back onto the same side of the table and share the same story to support commercial growth?
A few strong insights came through. Here's what they told me, and what it means for founders trying to make sense of their own marketing spend.
1. Marketing metrics need translation
Q: Marketing teams have more data than ever. So why do CFOs still struggle to trust it?
"It's not that marketing has no metrics. It's that the metrics need translation," one CFO told me.
Picture this: marketing reports traffic up 20%. The CFO comes back with, "why is revenue only up 5%?" Nobody's lying here. Traffic and revenue are connected by a chain — conversion rate, sales cycle, lead quality, time lag — and nobody has explained that chain out loud.
As one CFO put it, the issue isn't that marketing doesn't have a story. It's that marketing, sales and finance are telling the same story from different angles, and nobody has checked the angles add up. McKinsey's research backs this: 70% of CEOs say they measure marketing on year-over-year revenue and margin, but only 35% of CMOs track that as a top metric. That gap is exactly where trust breaks down.
2. CFOs can accept delayed ROI — if the logic is clear
Q: Do CFOs actually expect marketing to drive revenue immediately?
No — and this surprised me. One CFO was explicit:
I don't expect revenue from a brand-building phase straight away. But I need signals that show awareness is building, and a clear point where the business knows it's time to shift from brand to demand to conversion.
A credible ROI case, in his words, answers:
- What's the commercial target?
- What role does marketing play in getting there?
- Which stage are we investing in right now?
- What KPIs prove progress at this stage?
- When should impact show up?
- When do we move to the next stage?
- How do we adjust budget if the data says otherwise?
That last point matters most. A plan that can't flex isn't a strategy — it's a guess with a budget attached. This tracks with where the market is heading: NIQ's 2026 CMO Outlook found only 69% of marketing leaders still believe their CEO and CFO support long-term brand investment, down 11 points from the year before. The CFOs still willing to fund brand work aren't doing it on faith — they're doing it because someone showed them the staging logic.
3. The conversation must start before the budget is spent
Q: When should CFO and CMO actually be talking?
Before the spend, not after the results disappoint. Most CFO–CMO conversations happen reactively — after a quarter underperforms, after a board member asks an uncomfortable question. By then, you're already in defence mode.
The better model: get the CFO, CMO, sales lead and CEO in a room before a dollar is spent, and agree the commercial objective, marketing's role stage by stage, the budget split, the KPIs that prove each stage, and the conversion assumptions sales is comfortable with.
One CFO noted this matters even more when a fractional CMO joins a business — the CEO needs confidence that marketing can self-track with clear guardrails, rather than asking for sign-off at every step.
4. Marketing needs stage-based measurement
Q: How should measurement actually change given how non-linear buying journeys have become?
A fixed annual plan isn't enough anymore. CFOs described wanting a dynamic measurement model — tracking whether brand awareness is actually moving, whether demand is translating into pipeline, whether leads are converting, and reallocating budget mid-stream based on what the data says, not what the plan said in January.
Here's a high-level framework based on objective-led marketing activities from top to bottom of the funnel:
The discipline isn't the metrics themselves — it's agreeing before spend which metric belongs to which stage, and what "on track" looks like at each one. Without that, every number is just an artefact waiting to be misread by whoever's under the most pressure that quarter.
5. Cutting marketing is not always the right answer
Q: When performance dips, isn't marketing always first to get cut?
Not automatically — and CFOs themselves pushed back on this. One called it "a classic, knee-jerk reaction" and questioned whether it's right. Sometimes the dip is cyclical. Sometimes the business moved into lead generation before brand awareness was properly built, and the fix isn't less spend — it's a different sequence.
Instead, the recommendation was scenario planning at board level:
- What happens to demand if we cut?
- What happens if we hold the line?
- Could a stage-gate approach — dial down, watch for recovery signals, dial back up — work better than an all-or-nothing cut?
"The CFO's role is not just to cut cost. It's to help the business understand the options and the consequences," as one put it. That reframes the CFO from adversary to ally in the ROI conversation — which isn't how most marketers are taught to see the relationship.
6. AI makes senior marketing judgement more important, not less
Q: Does AI change any of this?
AI is an amplifier, not a substitute. If the underlying strategy is weak, AI just executes the wrong strategy faster and at greater scale. If the strategy is sound, AI lets good judgement compound.
Several CFOs expect AI to absorb more of the junior, repetitive marketing work — content production, outbound — which, in their view, makes senior marketing judgement more valuable, not less. The strategic thinking becomes the scarce resource, not the execution.
Why CFOs and CMOs Need One Marketing ROI Story
That is the simple solution to the conflicting CMO & CFO dynamics.
CFOs understand marketing ROI is hard to measure and all they need is a shared story and an early alignment of the commercial objectives, marketing strategies and KPIs at different stage of growth to justify the spend and answer the difficult questions from the board. What it required is that marketing, finance and sales shared one story, not that three functions narrating the same business from three different scripts.
So, this is the next conversation that needs to happen:
How can CFO and CMO build a full-funnel tracking model that explains marketing impact clearly enough to defend investment, especially when times get tough?
Because marketing investment shouldn't be a fight. It is not a cost centre, but a core part of the wider commercial strategies that backed by CEO, CFO and CCO, in any growing businesses.
