Your Budget Is Obsolete by March: 6 Rules for Planning That Actually Runs the Company

Somewhere this week, a finance team is sending out the spreadsheet. Department heads will have until October to fill in next year's numbers, the first version will be too optimistic in sales and too generous in costs, and three rounds of negotiation later the board will approve a document in December.

According to the 2026 AFP FP&A Benchmarking Survey, that ritual takes an average of 8.7 weeks, exactly as long as it took three years earlier, despite all the planning software companies have bought since. By March, a tariff, a currency move or a lost customer will have turned the approved number into fiction. And for the rest of the year, the organization will still be judged against it.

Jack Welch called the budgeting process at most companies "the most ineffective practice in management." He was not arguing against planning. He was arguing against a process that asks one document to do three incompatible jobs.

The traditional budget fails because it tries to be a target, a forecast and a resource allocation at the same time, and each of those jobs corrupts the other two.

Our group was founded in Azagra in 1890 and today operates eight active businesses selling into more than 75 countries, from wine and mineral water to real estate and hospitality. Businesses that different cannot be run from one frozen spreadsheet approved in December. Here are the six rules we apply to planning, whatever the sector.

Rule 1: Separate the target, the forecast and the budget

Bjarte Bogsnes, who led Statoil (now Equinor) when it abolished traditional budgets in 2005, makes the point better than anyone. A budget number is usually three numbers pretending to be one:

• The target is what we want to achieve. It should be ambitious.
• The forecast is what we honestly expect to happen. It should be accurate, not ambitious.
• The resource allocation is what we are prepared to spend. It should follow the best opportunities, not last year's spending.

When one number has to serve all three purposes, managers learn to shade it. Nobody forecasts honestly if the forecast becomes their target, and nobody asks for exactly what they need if the request becomes their ceiling.

Pull the three apart, give each its own conversation, and you remove the reason to game any of them. Equinor replaced its budget with a model it calls Ambition to Action, and since 2010 it has abandoned the calendar year wherever possible in favor of a rhythm set by business events.

Rule 2: Stop paying people against a negotiated number

In November 2001, the Harvard economist Michael Jensen published "Corporate Budgeting Is Broken, Let's Fix It" in Harvard Business Review, based on a paper with a blunter title: "Paying People to Lie." His argument was simple. When bonuses depend on beating a budget that the manager helped set, the manager has every reason to set it low, and then to hit it at any cost, even when that damages the company.

The damage compounds as it climbs the organization. A sales manager pads the forecast a little. The regional director, knowing the numbers below are uncertain, adds a buffer of their own. The country head does the same. By the time the plan reaches the board, it contains several layers of protection, none of them visible and all of them paid for in lost ambition.

If you want honest numbers, measure people against things they cannot negotiate: competitors, peers, prior years and the market.

Handelsbanken, the Swedish bank, is the longest-running proof. It stopped budgeting around 1970 under Jan Wallander and set itself a relative goal instead: a return on equity higher than the average of its competitors. According to BCG, it has achieved that goal every year since 1972. For more on designing pay that rewards owner-like behavior, read why your incentive plan is your real strategy.

Rule 3: Forecast on a rolling horizon, not a calendar

A budget treats December 31 as a wall. In February the company can see eleven months ahead, and by October it can see only two. That is exactly backwards: the closer you get to year-end, the less the plan tells you about what matters.

A rolling forecast fixes the horizon instead of the end date. Every quarter, you drop the quarter that has passed and add a new one, so you always look five quarters, or twelve to eighteen months, ahead.

Three disciplines make a rolling forecast worth the effort:

• Keep it light. A quarterly update that takes more than a few days will be abandoned.
• Measure accuracy and bias. Track how far each forecast was from reality, and whether it is consistently high or low. A forecast that is always optimistic is a hidden target.
• Never turn it into a target. The moment a forecast is used to judge performance, Rule 1 is broken and the gaming begins again.

Rule 4: Plan the few drivers that move the business, not every line

Most budgets are thousands of lines of false precision. Nobody can predict next October's stationery costs, and nobody should try. What moves a business is a handful of drivers, and those deserve all the attention.

In wine, the drivers are cases sold by market, price per case, product mix and the exchange rate. In a hotel, they are occupied room nights and the average rate. In real estate development, they are units sold, construction cost per square meter and the timing of cash in and out.

Identify the five to ten drivers that explain most of your results, plan those carefully, and let the rest of the numbers follow from them. When reality changes, you update one assumption and the whole forecast moves with it.

The time saved is real. APQC benchmarks of more than 3,900 organizations found that top performers complete the annual budget in 25 days or less, half the time of organizations in the 75th percentile.

Rule 5: Allocate money when the decision is due, not once a year

An annual budget decides in November what the company will spend in the following October, long before anyone knows whether that spending will still make sense. It also creates one of the most wasteful habits in management: spend it or lose it.

The evidence is not anecdotal. Jeffrey Liebman and Neale Mahoney studied US federal procurement, where budgets expire at the end of the fiscal year, in a paper published in the American Economic Review in 2017. Spending in the last week of the year was 4.9 times the weekly average for the rest of the year, and year-end IT projects received substantially lower quality ratings.

Money should be released when a project is ready to be decided, against the same hurdle every time, and not because a line in a year-old spreadsheet said it was available. That means holding capital centrally and allocating it continuously, as described in our six rules for deciding which capital projects get funded.

Rule 6: Replace the straitjacket with guardrails

The fear that stops most owners is loss of control. If there is no fixed budget, what stops costs from drifting? The answer is that a static budget was never good at controlling costs in the first place. It simply approved last year's costs plus inflation.

Guardrails work better:

• Ratios instead of fixed amounts. Cost as a percentage of revenue, or cost per unit produced, scales automatically with the business and cannot be defended by pointing at an old approval.
• Ranges and triggers. Agree the level at which a KPI must be escalated, rather than explaining every variance against an arbitrary number.
• A monthly business review built on the forecast. The question is not "why are you off budget" but "what has changed, and what are we doing about it."
• Hard limits where they matter. Banks, covenants and boards still need firm commitments on leverage, liquidity and investment. Keep those, and keep them few.

You do not need to abolish the budget overnight to get most of the benefit. Many companies keep a light annual plan for the board and the bank, and run the business on a rolling forecast and relative targets. If you are choosing which numbers to review every month, begin with the seven KPIs every CEO should track.

Key Takeaways

• A traditional budget fails because it forces one number to be a target, a forecast and a spending allowance at once. Separate the three.
• Paying people against a number they negotiated rewards low targets. Use relative measures: competitors, peers, prior years.
• Replace the calendar-year plan with a rolling forecast that always looks five quarters ahead, and measure its accuracy and bias.
• Plan the five to ten drivers that explain your results instead of thousands of lines of false precision.
• Allocate capital when decisions are ready, not once a year. Expiring budgets produce year-end spending sprees.
• Control costs with ratios, ranges and a monthly review of the forecast, and keep hard limits only where lenders and boards need them.

Frequently Asked Questions

What is the difference between a forecast and a budget?

A budget is a plan approved in advance that sets what a company intends to earn and spend over a fixed period, usually a year. A forecast is a regularly updated estimate of what is actually likely to happen, based on the latest information. The budget tells you what you hoped for; the forecast tells you where you are heading, which is why the two should not be the same number.

What is a rolling forecast?

A rolling forecast is a financial projection that always covers the same length of time ahead, typically twelve to eighteen months or five quarters. Each quarter or month, the period that has passed is dropped and a new one is added. Unlike an annual budget, its horizon never shrinks as the year goes on.

How long does the budget process take?

According to the 2026 AFP FP&A Benchmarking Survey, the average budget cycle takes 8.7 weeks, unchanged from three years earlier. APQC benchmarks show that top performers finish in 25 days or less, about half the time of organizations in the 75th percentile, largely by planning fewer lines around key drivers.

What does sandbagging a budget mean?

Sandbagging means deliberately setting a budget or forecast lower than what you expect to achieve, or asking for more resources than you need, so the target is easy to beat. It usually happens when bonuses are tied to budget performance. Across several management layers, small buffers add up to a plan far below the company's real potential.

What are the steps in the budget process?

A typical process runs through setting strategic goals, gathering assumptions, preparing department budgets, consolidating them, reviewing and negotiating, obtaining approval and monitoring variances during the year. Companies that move to rolling forecasts keep the goal-setting and monitoring steps, but replace most of the consolidation and negotiation with a quarterly update of a small set of drivers.

One thing to do this week

Take last year's approved budget and put it next to last year's actual results. Circle the three lines where the gap was largest, and ask one question about each: did we learn about that change in time to act, or did we find out when the year was already over? If the answer is the second one, your planning process is telling you history, not steering the company.
