What Is Flexible Budget?
At its heart, a Flexible Budget is a financial plan that's designed to adapt. Unlike a traditional or "static" budget, which is prepared for a single, specific level of activity (like selling 1,000 units), a flexible budget can be prepared for any level of activity within a relevant range. Imagine you budgeted to sell 1,000 widgets, but you actually sold 1,200. A static budget would just compare your actual 1,200-unit performance against the 1,000-unit budget, which isn't a fair comparison because your costs and revenues would naturally be higher at 1,200 units.
A Flexible Budget, however, would recalculate what your revenues and costs should have been for selling 1,200 units. This allows for a much more accurate evaluation of your operational efficiency, telling you if your expenses were controlled effectively for the actual work done, rather than penalizing or praising you just for selling more or less. It helps separate the impact of sales volume changes from the effectiveness of managing your costs and revenues.
