What is Flexible Budget?
A flexible budget is a budget that automatically adjusts revenue and variable cost lines to the actual level of activity achieved, rather than holding them at the original plan. It separates volume variances (driven by activity differences) from price and efficiency variances, enabling more meaningful performance analysis.
How It Works
- Build a static budget at planned activity (e.g., 10,000 units).
- Identify variable cost rates per unit and fixed cost block.
- Recalculate the budget at actual activity level (flex up or down).
- Compare actual results to the flexed budget to isolate price/efficiency variances.
- Use the difference between static and flexed budget as the volume variance.
Saudi Context
Saudi manufacturers and service businesses with significant variable cost components (raw materials, packaging, fuel, commission) implement flexible budgeting to manage seasonality (Ramadan demand spikes, summer slowdowns) and to compute manager bonuses based on controllable, activity-adjusted performance.
Example
A factory’s static budget at 10,000 units shows SAR 1,000,000 in materials cost (SAR 100/unit). Actual output is 8,000 units. The flexed materials budget is 8,000 * 100 = SAR 800,000. Actual materials spend SAR 880,000. Variance = SAR 80,000 unfavorable due to higher unit cost, isolated from the 2,000-unit volume shortfall.
