Financial Management and Budgeting
Domain 4 tests budgeting mechanics and the ability to read a variance without being misled by volume.
Budget types
- The operating budget covers recurring revenue and expense for the period; the capital budget covers multi-year asset purchases, justified by payback, NPV, or IRR.
- Incremental budgeting adjusts last year's figures; zero-based budgeting rebuilds each line from justification, costlier to run but effective at exposing slack.
- Fixed costs do not move with volume, variable costs do, and semi-variable costs contain both a base fee and a usage element.
Variance analysis
Standard costing compares actual results to a flexed budget, which is the original budget restated for actual volume. The total variance splits into a volume effect and a spending (rate) effect. A variance is favourable when profit is higher than expected or cost is lower.
Investment appraisal
NPV discounts future cash flows at the cost of capital; positive NPV adds value. IRR is the discount rate producing zero NPV. Payback ignores cash flow after the cut-off and the time value of money. Profit differs from cash: depreciation reduces profit but is not a cash outflow.
Controls
Segregation of duties separates authorisation, custody, and recording. Reconciliations, spending limits, and purchase-order thresholds are preventive controls; audits are detective.
Worked example
Material budget: 10,000 units at 5.00 each = 50,000. Actual: 11,000 units, 52,800 spent. The naive comparison shows a 2,800 overspend, which is wrong because volume rose. Flex the budget: 11,000 × 5.00 = 55,000. Spending variance = 55,000 − 52,800 = 2,200 favourable. Volume variance = 5,000 unfavourable, because more units were legitimately produced. The manager controlled price well; the gap is explained by output.
Traps that cost marks
- Comparing actual to the static budget when output changed.
- Calling a cost overrun unfavourable without checking the volume driver.
- Arguing a project is affordable from profit when cash timing is the real constraint.
- Submitting a capital request with an NPV but no identified funding source.
