Zero-based budgeting: what it really demands from a CFO

September 10, 2026 · 5 min · Free, with full transcript

Zero-based budgeting is sold as a cost-cutting trick, and that framing is what keeps failing. The episode argues ZBB is about knowing what you are buying, not spending less, and contrasts it with incremental budgeting, the last year plus 3 percent habit that protects decisions nobody remembers making. The Kraft Heinz and 3G Capital story, from the 2015 rollout to the 2019 $15 billion write-down, is used as the warning, while Unilever's find of duplicate analytics tooling shows where the money actually sits. Listeners leave knowing which categories to zero-base, software, travel, consulting, agencies and facilities, which to leave alone, how long a first pass takes, and why a ZBB template in a planning tool is not a decision.

Key takeaways

  • Apply zero-based budgeting to discretionary overhead such as software, travel, consulting, agencies and facilities, where 15 to 25 percent of a spend category can be redundant.
  • Do not zero-base cost of goods or anything set by contracts and volumes; you will rebuild a number that was already correct.
  • Name a cost owner for every category and make them defend the spend in front of peers, including events budgets with no measurable return.
  • Budget eight to 12 weeks for a serious first pass on discretionary spend at a mid-sized company, and treat weekend-fast tools as dashboards, not discipline.
  • Start Monday with one category, one named owner and a line-by-line justification from zero due by end of month rather than a company-wide rollout.

Host:Welcome to the Leaders Insights Podcast. Today's episode, Zero-Based Budgeting Revisited. What it actually demands from a CFO.

Expert:Zero-based budgeting has been buried more times than any finance idea I can think of.

Host:So why are we talking about a corpse?

Expert:Because it keeps getting dug up by the wrong people for the wrong reasons. Zero-based budgeting. The idea that every line item starts at zero each cycle and has to justify its existence isn't dead. It's just been sold as a cost-cutting magic trick. And that's a lie.

Host:A lie is strong. Kraft Heinz built a whole reputation on it.

Expert:They did, and look how that ended. 3G Capital ran zero-based budgeting across Kraft Heinz starting around 2015, cut billions, and by 2019, they took a $15 billion write-down and their brands were hollow. They cut so deep they stopped investing in the actual products. That's the cautionary tale everyone quotes and nobody learns from.

Host:So what does everyone get wrong?

Expert:They think zero-based budgeting is about spending less. It's not. It's about knowing what you're buying. The number at the bottom might go up. The point is you can defend every dollar instead of inheriting last year's number plus 3 percent because that's what the spreadsheet did while you slept.

Host:That plus 3 percent thing, you're saying that's the default in most companies?

Expert:It's the default in almost every company. It's called incremental budgeting. You take last year and nudge it. It's comfortable, it's fast, and it quietly protects every bad decision anyone made a decade ago. Nobody ever asks why the Prague office has a media agency retainer. It's just always been there, like a houseplant nobody remembers buying.

Host:Fine, so where does zero-based budgeting actually earn its keep?

Expert:Overhead you can't see the value of. Software subscriptions, travel, consulting, marketing agencies, facilities. Categories where the money leaks and nobody owns the total. Unilever ran a version of this and found redundant tooling, teams paying for four different analytics platforms that did the same thing. That's where you find real money, sometimes 15 to 25 percent of a spend category.

Host:And where is it a waste of everyone's time?

Expert:Waste of goods and anything tied directly to revenue. If you zero-base your raw materials, you're not budgeting, you're doing performance art. The inputs are set by contracts and volumes. You'll spend 40 hours rebuilding a number that was already correct. That's the quiet waste. CFOs apply it everywhere to look rigorous and burn their teams out for nothing.

Host:So what does it genuinely demand from a CFO? Not the brochure version.

Expert:Time in a stomach for a fight. Real zero-based budgeting means naming a cost owner for every category and making them defend it in front of peers. That's political. The head of sales does not enjoy explaining why events cost 1.4 million and generated nothing measurable. Your job is to hold that room and not blink.

Host:How long does a proper cycle actually take?

Expert:For a mid-sized company, a serious first pass on discretionary spend is eight to 12 weeks. Anyone selling you a tool that does it in a weekend is selling you a dashboard, not a discipline. And I'll flag it. AnnaPlan and vendors like them publish numbers on time saved that assume you've already done the hard human work of setting the cost drivers. The software doesn't decide whether the Prague retainer lives or dies. You do.

Host:You keep coming back to the human part. Is the technology overrated here?

Expert:The technology is fine for tracking. It's useless for judgment. The failure mode I see in 2026 is CFOs buying planning platforms and thinking they've done zero-based budgeting because the tool has a ZBB template. A template is not a decision. If nobody's uncomfortable, you haven't done it.

Host:So give me the one thing a CFO should do Monday morning.

Expert:Pick one discretionary category, software, travel, or agencies, and demand a named owner produce a line-by-line justification from zero by end of month. Just one. Don't boil the ocean. Don't roll it out company-wide with a fanfare. Prove the muscle works on a category where you already suspect the fat is. If it saves nothing, you've learned something. If it saves 20%, now you know where to point it next.

Host:One category, one owner, one deadline that I can use. Sources for today's episode. Financial Times Accounting Today, CFO dive. That's a wrap. Fresh CFO briefings drop daily at MBA-training.com.
