Eleven weeks to produce an annual budget is a long time to spend discovering that leadership still disagrees about the sales target. The spreadsheet gets blamed, naturally. It has the misfortune of being visible.
An October 23 CFO.com report on Accordion’s 2026 budgeting research found that surveyed private equity-backed CFOs take an average of 11 weeks to prepare a board-ready budget. Sixty-seven percent reported five or more full revisions. And 84% still build their core model in Excel.
That doesn’t prove Excel is the problem. The survey covered 100 CFOs at PE-backed businesses with at least $50 million in revenue, along with 100 PE operating partners. It’s a useful look at a demanding corner of corporate finance, not a benchmark for every company.
The more revealing finding is where the time goes: respondents attributed roughly 38% of their budgeting cycle to reconciling department inputs, 27% to reworking assumptions after sponsor feedback, 22% to board formatting and rebuilding, and just 13% to strategic analysis. To reduce annual budgeting cycle time, finance has to address that process—not simply give the model a faster engine.
Agree on the assumptions before inviting everyone into the model
Before departments submit numbers, the CFO and leadership team should settle the handful of assumptions that drive the plan: expected demand, pricing, gross margin, hiring capacity, major investments and the cash limits. Each assumption needs an owner, supporting evidence and a date when it will be reviewed.
Consider a hypothetical request to increase next year’s revenue plan by 8%. That is not a model instruction. It’s a question: more customers, higher prices, improved conversion, an acquisition, or some combination? Sales owns the evidence. Operations confirms capacity. Finance shows the margin and working-capital consequences.
If the evidence isn’t there yet, keep the 8% as an upside scenario. Leadership can still set a stretch target. It just shouldn’t quietly replace the expected forecast because the slide looked lonely without it.
Make late changes earn another revision
A late edit isn’t automatically a reason to reopen the whole budget. First classify it. Is it a data correction? A real change in the business? Or a negotiation over what management wants the number to be?
Corrections should be fixed and logged. A material new customer loss, contract win or cost increase may justify a fresh scenario and revised approval. A preference for a tidier EBITDA number is a leadership trade-off, not a discovery about the future.
For each proposed change, require a short decision record: the assumption being changed, who requested it, the supporting evidence, its effect on revenue, EBITDA and cash, and who can approve it. Agree on materiality thresholds in advance. For example, a company might require escalation when a change alters projected EBITDA by at least 2%; that’s an illustrative internal policy, not an industry standard.
Smaller items can often wait for the next forecast refresh. Serious changes still deserve immediate attention. Speeding up the calendar by ignoring real information would be a peculiar achievement.
Automate the reconciliation, not the judgment
Finance should absolutely stop spending days comparing department files, hunting down version differences and repairing board tables. Standardized input definitions, controlled source data, automatic reconciliations and a visible change log can make those tasks more reliable.
AI may help flag inconsistent assumptions or explain where versions diverge. But the Accordion survey’s allocation of time does not mean 87% of budgeting can safely be automated. Sponsor feedback, quality checks and judgment still have to happen. The useful dividing line is whether a task prepares information or decides what the business should do with it.
Track the process accordingly: calendar days from kickoff to approval, days spent waiting for inputs, number of full revisions, exceptions approved after the assumptions deadline, and the portion of finance’s time spent testing decisions rather than formatting them. Those measures tell a CFO whether the next investment should be a tool, a better approval process, or a firmer meeting agenda.
Keep the annual budget and current forecast separate
The approved budget records the resource decisions leadership made. The current forecast records what the business now expects. They should reconcile, but they don’t have to agree.
When a new contract lands after budget approval, update the forecast and show its consequences. Don’t rewrite the original budget just to make an old decision look clairvoyant. That destroys the comparison management needs to learn from it.
An efficient budget cycle creates time for the questions finance is paid to answer: Which investment gets funded? Which assumption deserves skepticism? What happens to cash if the upside arrives three months late?
The Schlott Company helps finance teams build driver-based planning models, scenario analysis and management reporting that make those decisions easier to see.
