Zero-based budgeting (ZBB) has died and been resurrected so many times that declaring it dead again risks sounding like just another cycle in the pattern. I’m making the claim anyway, because this time the death isn’t cyclical – it’s structural. The operating conditions zero-based budgeting was built for no longer match the conditions most companies are actually planning in, and the methodology hasn’t adapted fast enough to survive the mismatch.

A Brief, Honest History of a Methodology That Keeps Almost Working

Zero-based budgeting isn’t a new idea dressed up in new language. It dates to the early 1970s, when Peter Pyhrr developed it at Texas Instruments and Georgia Governor Jimmy Carter adopted it for state government. When Carter became president in 1976, he mandated zero-based budget methodology across every federal agency starting in 1977 – an ambitious, government-wide experiment in making every dollar justify itself from scratch every year, with no default carryover from the prior year’s baseline. It failed. The scale of the federal budget, the paperwork burden, and bureaucratic resistance overwhelmed the process, and the Reagan administration quietly abandoned the mandate in 1981. ZBB spent the following two decades largely dismissed as an impractical management fad.

It came roaring back around 2010-2014, driven primarily by 3G Capital, the private equity firm behind aggressive cost discipline at companies like Kraft Heinz, which turned budget-based zero thinking into a Wall Street-friendly cost-cutting story. And for a while, it worked as a story. Then it stopped working as a business outcome. Kraft Heinz, the company most associated with the modern ZBB revival, saw its share price drop 29% in 2019 as its relentlessly cost-focused strategy created what internal accounts described as a high-pressure, anxious operating environment that ultimately undermined the brand investment and growth the business needed.

That’s not an isolated cautionary tale. It’s the pattern.

What Is a Zero-Based Budget Actually Optimizing For, And Why That’s the Problem

The core promise of a zero-based budget is simple and genuinely appealing. Instead of rolling forward last year’s spending and adjusting at the margins, every expense has to be justified from zero, every cycle, based on current priorities rather than historical inertia. In theory, that eliminates legacy waste and forces alignment between spend and strategy.

In practice, the McKinsey research most frequently cited in favor of ZBB tells a more complicated story than the pitch suggests. A survey of more than 300 global companies using ZBB found average annual savings of $280 million, a genuinely large number, but among companies that announced cost reduction programs under this kind of discipline, only 26% were able to sustain those reductions for four years, and only 17% went on to achieve actual growth afterward.

Sit with those two numbers together, and ZBB is genuinely good at producing a large, one-time cost reduction. It is not good, at scale, at sustaining that discipline or converting it into growth. That’s not an implementation failure at one or two companies. That’s a structural pattern across the methodology itself, and it points to exactly what’s wrong with treating zero-based budgeting as an annual ritual rather than an ongoing operating discipline.

Why the Method Breaks Down at Scale

There are three specific reasons zero-based budgeting consistently produces a short-term win and a long-term drag, and understanding them is the key to understanding what should replace it.

1. It’s a once-a-year event applied to a continuous problem

Classic ZBB happens during the annual budget cycle. Every line justified from zero, once, and then largely locked in for twelve months. But spend conditions, market pressure, and strategic priorities don’t hold still for a year. A zero-based budgeting system built around an annual reset is structurally unable to respond to the eleven months of change that happen after the budget is finalized, which is exactly why so many ZBB implementations feel rigorous in January and irrelevant by June.

2. The paperwork burden creates its own dysfunction

This was true during the Carter administration’s failed federal experiment, and it’s still true in modern corporate implementations: justifying every line item from scratch generates an enormous amount of documentation and review work, disproportionate to the strategic value of scrutinizing, say, a stable, well-run facilities budget with the same intensity as a volatile marketing spend line. Zero-based budgeting advantages and disadvantages discussions tend to undersell how much this administrative burden erodes the very discipline ZBB is supposed to create, because exhausted teams start rubber-stamping justifications just to get through the cycle.

3. It optimizes for cost, not for capital allocation

ZBB is fundamentally a cost-justification exercise. It answers, “can this expense be justified”, far better than it answers, “is this the best use of this dollar compared to every other option available to us.” Those are different questions, and the second one is the one that actually drives growth. A budget that survives zero-based scrutiny by having a defensible justification isn’t the same as a budget that represents the optimal allocation of scarce capital, which is precisely the gap that turned Kraft Heinz’s cost discipline into a growth problem.

What’s Actually Replacing It

The companies getting real, sustained spend discipline in 2026 aren’t running a better version of the annual ZBB ritual. They’re replacing the ritual with continuous, driver-based, and technology-enabled planning that keeps the good instinct behind ZBB – nothing gets funded by default while fixing its structural weaknesses.

1. Driver-based, continuous planning instead of an annual reset

Rather than justifying every line item once a year, driver-based planning ties budget allocations to the operational metrics that actually move the business, like headcount, transaction volume, and customer growth, and updates automatically as those drivers change. This preserves ZBB’s core discipline (spend has to be justified by something real) without the once-a-year rigidity that makes classic ZBB stale by the second quarter.

2. Rolling forecasts layered with targeted, not universal, zero-basing

Instead of applying zero-based budgeting intensity uniformly across every cost line, spend-conscious CFOs are increasingly applying it selectively to volatile, discretionary, or historically bloated categories while running stable, predictable cost centers on a rolling forecast basis. Gartner’s 2026 CFO priorities survey found that 51% of CFOs rank improving financial forecast accuracy and quality among their top five priorities, alongside 56% ranking enterprise-wide cost optimization in their top five both priorities pointing toward continuous accuracy and targeted discipline, not a once-a-year, blanket exercise.

3. Real-time spend visibility replacing after-the-fact budget justification

This is where the discipline actually lives now, and it’s a fundamentally different mechanism than a budgeting methodology. Instead of forcing every line to be re-justified annually, modern zero-based budget software and spend platforms enforce discipline transactionally, every purchase, expense, and invoice validated against policy and budget availability at the moment it happens, not reconstructed after the fact during a budget cycle. That turns “justify every dollar” from an annual paperwork exercise into a continuous, low-friction control embedded in how money actually moves.

4. AI-assisted scenario modeling instead of manual line-item review

Some of the zero-based budgeting tools gaining traction now use AI specifically to reduce the administrative burden that sank both the federal ZBB experiment and countless corporate rollouts, automatically flagging line items that deviate meaningfully from operational drivers or historical patterns, so human review time concentrates on the handful of genuinely questionable items instead of being spread evenly and exhaustingly across every line, regardless of its actual risk.

The Honest Version of What Still Works

None of this means the underlying instinct behind ZBB was wrong. “Don’t let spend continue by default just because it happened last year” is a genuinely good principle, and any zero-based budget apps or planning tool worth adopting should preserve it. What’s dead isn’t the principle; it’s the specific operational form of an annual, universal, paperwork-heavy justification ritual that Carter’s administration couldn’t scale in 1977 and that Kraft Heinz’s board learned the hard way couldn’t scale in 2019 either.

The replacement isn’t a rejection of budget discipline. It’s a more honest admission that discipline applied uniformly, once a year, through a paperwork-heavy process, produces exactly the pattern McKinsey’s own data shows: real short-term savings, poor four-year sustainability, and weak conversion into growth. Continuous, driver-based, transactionally enforced spend control fixes the timing problem and the paperwork problem simultaneously, which is precisely why it’s what spend-conscious companies are actually building toward, whatever they choose to call it internally.

What CFOs Should Actually Ask Before Their Next Budget Cycle

• Are we applying zero-based scrutiny uniformly, or targeting it at the volatile and discretionary categories where it actually adds value?
• Is our spend discipline enforced continuously, at the point of transaction, or only reconstructed once a year during budget season?
• When we cut costs this cycle, do we have a mechanism to prevent quiet reversion to the old baseline eleven months from now?
• Are we measuring sustained savings over multiple years, or just celebrating the first-year number the way most ZBB case studies do?

If your organization can’t answer the third question with confidence, you don’t have zero-based budgeting. You have an annual cost-cutting event with a name borrowed from a more rigorous idea, and the data on how well that pattern sustains itself should worry you more than it currently does.
