Calculate the maximum profit that can be made in a month. 12. Rehan a first semester student at a college, decided to start a trading business buying formal dress shirts for $10 from an overseas country and selling them to his college peers for $35 each. As he is not good at selling, he hired his friend Ruby to sell these shirts and paid her 10% of the selling price as commission on every shirt she sold. If he spent a flat rate of $20 on storage charges every month and could only purchase a maximum of 500 shirts every month from his overseas vendor, calculate the maximum monthly profit that he can make in his business. 7.4 | Contribution Margin Ratio In Sections 7.2 and 7.3 you learned Cost-Volume-Profit (CVP) analysis and the Contribution Margin (CM) approach to CVP analysis. CVP analysis provides a relationship among the Selling Price (S), Total Revenue (TR), Variable Costs (VC), Total Variable Costs (TVC), Fixed Costs (FC), Quantity (x) produced, and Net Income (NI). The CM approach provides information on the dollar amount from each unit of sales that is available to cover the fixed costs and contribute towards the operating profits (Net Income). In this section, you will learn about the Contribution Margin Ratio (CM ratio), which provides information on the percent of each sales dollar that is available to cover fixed costs and contribute to the net income. Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Contribution Margin Ratio (CM Ratio) The Total Contribution Margin (TCM) as a percent of the Total Sales Revenue (TR) is called the Contribution Margin Ratio. Total Contribution Margin = Total Revenue - Total Variable Costs Therefore, CM Ratio = Formula 7.4(a) Total Revenue - Total Variable Costs # 100% Total Revenue = TR - TVC # 100% TR Contribution Margin Ratio CM Ratio = For example, if the Total Sales are $200,000 and the Total Variable Costs are $140,000 then, Using Formula 7.4(a), CM Ratio = = 200, 000 - 140, 000 # 100 % 200, 000 60, 000 # 100% 200, 000 = 30.00% The CM ratio measures the effect of Net Income when the Sales Revenue increases or decreases; i.e., for each dollar increase in sales, the total contribution will increase by the amount equal to the CM ratio and the Net Income will also increase by the amount equal to the CM ratio, provided that the fixed costs remain the same. In the above example, if $20,000 in sales are added, then the net income will increase by 30% of $20,000, which is equal to $6000. The Contribution Margin Ratio is most useful when the increase or decrease in sales volume is measured in sales amount. The Net income (NI) can also be calculated using the CM ratio, as follows: Formula 7.4(b) Net Income NI = (CM Ratio × TR) - FC The relationship among Total Revenue (Sales Amount), Total Variable Costs, Contribution Margin, Contribution Margin Ratio, Fixed Costs, and Net Income is shown in the following diagram in a table form (vertical analysis): - - Total Amount Unit Price Sales TR S Variable Costs TVC VC Contribution Margin TCM CM Fixed Costs FC Net Income NI Percent of Sales 237 238 Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Example 7.4(a) Calculating the Contribution Ratio and Net Income A company reported the following statement: Number of units produced: 2000 Selling price per unit: $30 Variable cost per unit: $12 Fixed costs: $15,000 Calculate the contribution margin ratio and net income. Solution Total Amount Unit Price Percent of Sales $60,000.00 $30.00 100% - TVC $24,000.00 $12.00 40% TCM $36,000.00 $18.00 60% TR - FC $15,000.00 NI $21,000.00 From Formula 7.4(a), CM Ratio = Substituting the values, TR - TVC # 100% TR = 60, 000.00 - 24, 000.00 # 100 % 60, 000.00 = 36, 000.00 # 100 % 60, 000.00 = 60.00% From Formula 7.4(a), NI = (CM Ratio × TR) - FC Substituting the values, = (0.60 × 60,000.00) - 15,000.00 = 36,000.00 - 15,000.00 = $21,000.00 Therefore, the contribution margin ratio of the company was 60.00% and the net income was $21,000.00. Example 7.4(b) Calculating the Total Revenue Required to Break-Even, Given TVC as a Percent of TR The variable costs of a product that a firm manufactures are 40% of selling price. The fixed costs per year are $150,000. Calculate the break-even point in sales dollars. Solution At the break-even point in sales, Net Income = 0 Therefore, TCM = FC = $150,000.00 TVC = 0.40TR TCM = 0.60TR 0.60TR = 150,000.00 TR Total Amount % of Sales $250,000.00 100% - TVC TCM - FC 40% $150,000.00 $150,000.00 TR = $250,000.00 NI Therefore, the break-even point in sales dollars is $250,000.00 0 60% Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Example 7.4(c) 239 Calculating the Sales Amount and the Contribution Margin Ratio, Given NI, TVC, and FC The net income of a manufacturing company was $250,000. The variable costs are $192,500 and fixed costs are $107,500. (i) Calculate the amount of sales. (ii) Calculate the contribution margin ratio. (iii) Calculate the amount of sales at break-even point. Solution Total Amount % of Sales $550,000.00 TR - TVC $192,500.00 TCM $357,500.00 - FC $107,500.00 NI $250,000.00 (i) Using, 65% TCM - FC = NI TCM = FC + NI Substituting the values, = 107,500.00 + 250,000.00 = $357,500.00 Using, TR - TVC = TCM TR = TVC + TCM Substituting the values, = 192,500.00 + 357,500.00 = $550,000.00 Therefore, the amount of sales was $550,000.00. (ii) Using CM Ratio = Substituting the values, TCM # 100 % TR = 357, 500.00 # 100 % 550, 000.00 = 65.00% Therefore, the contribution margin ratio is 65.00%. (iii) At break-even, Net Income = 0 Therefore, Total Contribution Margin = Total Fixed Costs = $107,500.00 Using, TCM CM Ratio = TR # 100 % 107, 500.00 Substituting the values, 65% = # 100 % TR TR = 107, 500.00 # 100 0.65 = $165,384.62 Total Amount TR % of Sales $165,384.62 - TVC TCM $107,500.00 - FC $107,500.00 NI Therefore, the amount of sales at break-even point is $165,384.62. 0 65% 240 Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Example 7.4(d) Calculating the Additional Sales Required to Break-Even When Variable Costs Increase Alfred Yeung Toys and Gifts has a fixed cost of $360,000 per annum and the variable costs are 70% of sales. If the variable costs increased to 75% of sales, what additional sales must be made to break-even? Solution Sales at break-even when TVC = 0.70TR Total Amount % of Sales 100% TR - TVC TCM - FC 70% $360,000.00 30% $360,000.00 0 NI TVC = 0.70TR At BE, NI = 0 Therefore, TCM = FC = 360,000.00 Also, TCM = TR - 0.70TR = 0.30TR 360, 000.00 0.30 TR = TR = $1,200,000.00 Sales at break-even when TVC = 0.75TR Total Amount 100% TR - TVC TCM - FC % of Sales 75% $360,000.00 25% $360,000.00 NI 0 TVC = 0.75TR At BE, NI = 0 Therefore, TCM = FC = 360,000.00 Also, TCM = TR - 0.75TR = 0.25TR 360, 000.00 0.25 TR = $1,440,000.00 TR = Therefore, the additional sales required to break-even is: 1,440,000.00 - 1,200,000.00 = $240,000.00 Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Example 7.4(e) 241 Calculating the Change in Net Income when the Selling Price is Reduced and the Sales Volume is Increased A manufacturer of air-conditioning units has fixed costs of $120,000 per annum. The variable costs are 40% of sales and profit was $66,000. When the selling price was reduced by 2%, the sales volume increased by 24%. (i) What was the original sales revenue? (ii) What were the original variable costs? (iii) What is the new sales revenue? (iv) What are the new variable costs? (v) What is the amount of change in net income? Solution Using, Contribution margin - Fixed costs = Net income Rearranging, TCM = FC + NI Substituting the values, = 120,000.00 + 66,000.00 = $186,000.00 TCM = TR - TVC Substituting the values, = TR - 0.40TR = 0.60TR Therefore, 0.60TR = 186,000.00 186, 000.00 (i) TR = S= 0.60 = $310,000.00 Total Amount % of Sales TR $310,000.00 100% - TVC $124,000.00 40% TCM $186,000.00 60% - FC $120,000.00 NI $66,000.00 Therefore, the original sales revenue is $310,000.00. (ii) TVC = 0.40TR = 0.40 × 310,000.00 = $124,000.00 Therefore, the original variable costs are $124,000.00. (iii) When the sale price was reduced by 2%, the sales volume increased by 24%. Therefore, the new sales amount is equal to: Total Amount = 310,000.00(1 - 0.02)(1 + 0.24) TR $376,712.00 = 310,000.00 × 0.98 × 1.24 = $376,712.00 % of Sales - TVC 100% 40% TCM $226,027.20 - FC (iv)New TVC = 0.40TR = 0.40 × 376,712.00 NI = $150,684.80 Therefore, the new variable cost is $150,684.80. $120,000.00 $106,027.20 (v)TCM = 0.60TR = 0.60 × 376,712.00 = $226,027.20 NI = TCM - FC = 226,027.20 - 120,000.00 = $106,027.20 Therefore, the change in net income = $106,027.20 - $66,000.00 = $40,027.20 60% 242 Chapter 7 | Break-Even and Cost-Volume-Profit Analysis Example 7.4(f) Calculating the Change in Net Income when the Contribution Margin Rate Changes A manufacturer of computer keyboards has fixed costs of $100,000. The variable costs are 80% of the sales. (i) What is the sales revenue at break-even? (ii) What are the variable costs at break-even? (iii) If the contribution margin rate is increased by 20% of sales and the fixed costs are increased by $25,000, calculate the new sales revenue at break-even. (iv) After the changes in the contribution margin rate and the fixed costs, calculate the net income when the sales are $400,000. Solution (i), (ii) When TVC = 80%TR (i) At Break-even,NI = 0 Therefore, TCM = FC = $100,000.00 % of Sales TCM = TR - TVC Substituting the values, 100,000 = TR - 0.80TR 100,000 = 0.20TR TR $500,000.00 100% - TVC $400,000.00 80% TCM $100,000.00 20% Therefore, - FC Total Amount 0.20TR = 100,000.00 100, 000.00 TRS = 0.20 $100,000.00 0 NI = $500,000.00 Therefore, the sales revenue at break-even is $500,000.00. (ii) TVC = 0.80TR = 0.80 × 500,000.00 = $400,000.00 Therefore, the total variable costs at break-even are $400,000.00.
