Preparing and presenting reports on actual costs
Purpose of cost reports
Actual cost reports tell managers what has been spent, compare it with the plan, and prompt corrective action. A good report shows the cost centre, the period, who prepared it and who it is for, and it must be produced on time - a late report has little value.
Comparing actual with budget
A fair comparison needs a flexed budget: the original budget recalculated at the actual level of activity, so variable costs are compared like with like. The difference between the flexed budget and actual is a variance. Favourable (F) means profit is better than planned - actual cost below budget for a cost, actual revenue above budget for income; adverse (A) is the reverse. Fixed costs are compared with the original budget because they do not flex.
Presentation
Use a clear table: cost line, flexed budget, actual, variance, F/A. Add a short narrative explaining significant variances and recommending action. Many marks are lost by presenting figures without explanation. Keep units and rounding consistent and make sure totals reconcile.
Worked example. Budget: 10,000 units, materials £50,000 (so £5.00 per unit). Actual: 11,000 units, materials £56,000. Flexed budget = £5.00 × 11,000 = £55,000. Variance = £56,000 − £55,000 = £1,000 adverse.
Traps: comparing actual results with the un-flexed budget; labelling a cost overspend as favourable; giving totals with no analysis; omitting the period, currency or units.
