1 Costing 2 Accounting Prof. Clive Vlieland-Boddy Academic Year
2 Activity Based Costing
3 Costs per service or activity. Costs are allocated to a service or activity Examples: Cost per sales enquiry Costs per warranty claim Costs per credit check
4 Cost Drivers There are two main types of cost driver: A resource driver, which refers to the contribution of the quantity of resources used to the cost of an activity. An activity driver, which refers to the costs incurred by the activities required to complete a particular task or project.
5 Activity-Based Costing A way to allocate as many costs as possible to a product Focuses on activities and cost of activities Each activity has its own cost driver Uses a separate allocation rate for each activity
6 Other Costing Issues
7 Job Costing Measures individual costs of production or service to each sales unit. Example: A builder will charge to a job all the materials and labour so as to identify the results of that particular job.
8 Processing Costing Traces all direct an indirect costs of manufacturing often on a batch process. They eventually divide these costs up to calculate a per unit cost.
9 Conversion Costs
10 Equivalent Units When valuing ending inventories of WIP, there may well be many partly completed units. These have to be equated into completed units. Example: At the month end a cycle manufacture has 500 half completed cycles. That would equate to 250 equivalent units.
11 Cost Volume Profit Analysis (CVP) & Break Even
12 The principles of variable/marginal costing 1.For any given period of time, fixed costs will be the same, for any volume of sales and production (provided that the level of activity is within the relevant range). Therefore, selling an extra item of product or service: Revenue will increase by the sales volume of the item sold Costs will increase by the variable cost per unit Profit will increase by the amount of contribution earned from the extra item
13 Cost-volume-profit analysis Systematic method of examining the relationship between changes in activity and changes in total sales revenue, expenses and net profit CVP analysis is subject to a number of underlying assumptions and limitations The objective of CVP analysis is to establish what will happen to the financial results if a specified level of activity or volume fluctuates
14 CVP analysis assumptions All other variables remain constant A single product or constant sales mix Total costs and total revenue are linear functions of output The analysis applies to the relevant range only Costs can be accurately divided into their fixed and variable elements The analysis applies only to a short-time horizon Complexity-related fixed costs do not change
15 Break Even

17 Margin of safety The extent that the revenue exceeds total costs, is called the margin of safety. Indicates by how much sales may decrease before a loss occurs
18 Break Even Analysis Remember: A higher price or lower price does not mean that break even will never be reached! The break even point depends on the number of sales needed to generate revenue to cover costs – the break even chart is NOT time related!
19 Activity Use the matrix on web site to do this
22 Budgets Estimates of the income and expenditure of a business or a part of a business over a time period Used extensively in planning Helps establish efficient use of resources Help monitor cash flow and identify departures from plans Maintains a focus and discipline for those involved
23 Budgets Flexible Budgets – budgets that take account of changing business conditions Static Budget – Based on pre determined level of activity
25 Flexible Budget This is the budget we would have prepared HAD WE ONLY KNOWN the number of units that would be sold or produced
26 What is needed to do a flexible budget To do a flexible budget we need to know the assumptions used to create the original budget – Units expected to be sold – Expected selling price per unit – Variable cost per unit – Fixed costs (in total)
31 Actual Vs Budget Actual Budget Variance Sales540, ,000 20,000 F Purchases350, ,000 10,000 U Because it is a positive variance the it is marked with a F. Unfavourable is marked with a U
32 Budgets Variance – the difference between planned values and actual values – Positive or Favourable variance – actual figures less than planned – Negative Unfavourable variance – actual figures above planned
34 Quantity variancePrice variance The difference between the actual price and the standard price The difference between the actual quantity and the standard quantity Standard variances Revenue or Cost Variance Analysis
35 Easier than formulas? Sales volume variance – (actual units – planned units) * planned selling price per unit Sales price variance – (actual unit price – budgeted unit price) * units sold Note: Some companies use contribution margin per unit instead of selling price to compute these variances.
36 Drilling down further... Sales volume variance can be further analyzed – Are sales more or less than expected because we sold a different mix of products than we planned? – The selling price for each product might also be different than we planned
37 Production Variances Direct materials – Price variance – Quantity variance The computations are similar to what we illustrated for sales. You change one element at a time and, from the difference, determine the impact on costs (instead of sales)
38 Direct labor – Rate variance – Efficiency variance
39 Maybe I can attribute the labour and materials variances to personnel for hiring the wrong people and training them poorly. Responsibility for Labour Variances
43 Report financial performance of responsibility centers Cost center Difference between actual results and budget Changes in labour dollars or hours Changes in purchased price vs. quantity discount Revenue center Variance due to selling more or less units than expected Variance due to price changes Profit center – Focus on both revenue and cost variances Copyright (c) 2009 Prentice Hall.

44 Management by exception – Only material variances are investigated Should focus on information, not blame Some variances are uncontrollable – Examples: increase in costs due to a natural disaster or macro economic issues Copyright (c) 2009 Prentice Hall. All rights reserved.44
