From budget variance to a management decision
A useful variance review explains the driver, tests whether it persists and assigns an action.
Explain
Separate the change into understandable drivers.
Decide
Identify what management can influence.
Follow through
Record an owner, deadline and measure.
Start with the question the decision-maker needs answered
A report that says revenue is below budget identifies a difference. The next conversation needs to establish why it happened and whether the forecast should change. Ask whether the issue is volume, price, timing, mix or a data problem. Agree on the meaning of each driver before building the bridge.
Budget: 1,000 units × SAR 100. Actual: 900 units × SAR 95. These are fictional figures.
Build a bridge that reconciles
| Driver | Calculation | SAR |
|---|---|---|
| Volume at budget price | (900 − 1,000) × 100 | −10,000 |
| Price at actual volume | (95 − 100) × 900 | −4,500 |
| Total change | 85,500 − 100,000 | −14,500 |
This convention reconciles the difference for a single service without double-counting the interaction. Multiple products, currencies or changing mix require a more detailed bridge. State the chosen method so that successive reviews remain comparable.
Turn the explanation into a decision
For volume, ask whether the shortfall reflects demand, delayed delivery or capacity. For price, distinguish an approved discount from an unplanned leakage. The commercial owner can then propose a response, while finance tests the expected revenue and margin effect.
Do not treat every adverse variance as a problem to reverse. A deliberate price reduction could support a different objective. Review the decision against contribution, capacity and cash implications, not revenue alone.
Close the loop in the next review
Record the action, owner, due date and expected effect. At the next meeting, compare the observed result with that expectation. If the cause is persistent, update the forecast assumptions explicitly. If it is timing, track the expected reversal rather than silently carrying it forward.
Use this meeting prompt
What changed? What evidence supports the cause? Is it temporary or recurring? What can we influence? Who will act, by when, and what result will we check?
Original Practical Finance worked example. All figures are fictional; calculations are shown in full. This is a management-analysis workflow, not an accounting-standard requirement.
