    Volume-Cost-Profit Analysis

    The cost-volume-profit (CVP) analysis is a tool to show therelationship between various ingredients of profit

    planning, namely, unit sales price (SP), unit

    variable cost (VC), fixed costs (FC), salesvolume, and sales-mix (in the case of

    multi-product firms).

    The crucial step in this analysis is the determination of

    break-even point (BEP), which is defined as the saleslevel at which the total revenues equal total costs.

    It is the level at which losses cease and beyondwhich profit starts.

    1(a) Contribution MarginApproach

    Contribution margin is the excess of unit sale price over unit variable cost

    Example 1: How many ice-creams, having a unit cost of Rs 2 and a selling

    price of Rs 3, must a vendor sell in a fair to recover the Rs 800 fees paid by

    him for getting a selling stall and additional cost of Rs 400 to install the

    stall? The answer can be determined by dividing the fixed cost by thedifference between the selling price (Rs 3) and cost price (Rs 2). Thus

    BEP (units) =Fixed cost (Entry fees + Stall expenses)

    (Sales price Unit variable cost)

    (Rs 800 + Rs 400)/(Rs 3 Rs 2) = 1,200 units

    BEP (units) =Fixed costs

    Contribution margin (CM) per unit

    BEP (amount)/BEP (Sales revenue)/BESR = BEP (units) Selling price (SP)

    per unit = 1,200 Rs 3 = Rs 3,600

    Dr. Shailendra Kumar, LMTSOM, Thapar University, Patiala 16-6

    BEP (amount) =Fixed costs

    Profit volume ratio (P/V ratio)

    P/V ratio =

    Contribution margin per unit

    Selling price per unit

    BEP (amount) = Rs 1,200 0.3333 = Rs 3,600

    From the P/V ratio, the variable cost to volume ratio (V/V ratio) can be easily

    derived:

    V/V ratio = 1 P/V ratio

    In the vendors case, it is = 11/3 = 2/3 = 66.67 per cent

    The V/V ratio, as the name suggests, establishes the relationship between

    variable costs (VC) and sales volume in amount. The direct method of its

    computation is:

    Variable cost = Rs 2 Rs 3 = 66.67 per centSales revenue

    Thus, P/V ratio + V/V ratio = 1 or 100 per cent

    (1/3 + 2/3) = 1 (33.33 per cent + 66.67 per cent) = 100 per cent

    Margin of Safety

    Margin of safety is the excess of actual sales revenue over the break-evensales revenue.

    The excess of the actual sales revenue (ASR) over the break-even sales revenue(BESR) is known as the margin of safety. Symbolically, margin of safety = (ASR

    BESR)

    When the margin of safety (amount) is divided by the actual sales (amount), themargin of safety ratio (M/S ratio) is obtained. Symbolically,

    M/S ratio = (ASR BESR)/ASR

    Assume in the vendors case that sales is 2,000 units (Rs 6,000); margin ofsafety (Rs 6,000 Rs 3,600) = Rs 2,400; and the M/S ratio is Rs 2,400 Rs 6,000= 40 per cent.

    The amount of profit can be directly determined with reference to the margin ofsafety and P/V ratio. Symbolically,

    Profit = [Margin of safety (amount)] P/V ratio

    Or Profit = [Margin of safety (units) CM per unit]

    In the vendors case, profit = Rs 2,400 0.3333 (33.33 per cent) = Rs 800 or 800 Re 1 = Rs 800.

    The reason is that once the total amount of fixed costs has been recovered,profits will increase by the difference of sales revenue and variable costs.

    1( b) Equation technique

    The equation technique is particularly useful in

    situations where unit price and unit variable costs arenot clearly defined. The excess of actual sales over theBE sales is the margin of safety. When margin of safetyis divided by the actual sales, we get margin of safetyratio which indicates the percentage by which actualsales may decline without causing any loss to the firm

    Sales revenue-Total costs = Net profit

    Breaking up total costs into fixed and variable, Sales revenue Fixed

    costs Variable costs= Net profit. Or Sales revenue = Fixed costs +

    Variable costs + Net profit.

    If S be the number of units required for break-even and sales revenue

    (SP) and variable costs (VC) are on per unit basis, the above equation

    can be written as follows:

    SP (S) = FC + VC (S) + NI

    Where SP = Selling price per unit

    S= Number of units required to be sold to break-even

    FC= Total fixed costs

    VC= Variable costs per unit

    NI= Net income (zero)

    SP (S)= FC + VC (S) + zero

    SP (S) VC (S)= FC

    Example 2

    SV Ltd, a multi-product company, furnishes you the following datarelating to the current year:

    Particulars First half of the year Second half of the year

    Sales

    Total costs

    Rs 45,000

    40,000

    Rs 50,000

    43,000

    Assuming that there is no change in prices and variable costs andthat the fixed expenses are incurred equally in the two half-year

    periods, calculate for the year:(i)The profit-volume ratio, (ii) Fixed expenses, (iii) Break-even sales,and (iv) Percentage margin of safety.

    Solution

    Sales revenue Total costs = Net profitRs 45,000 Rs 40,000 = Rs 5,000 (first half)

    Rs 50,000 Rs 43,000 = Rs 7,000 (second half)

    On a differential basis: Sales revenue, Rs 5,000 Total costs, Rs3,000 = Total profit, Rs 2,000.

    Dr. Shailendra Kumar, LMTSOM, Thapar University, Patiala 16-11

    We know that only VC changes with a change in sales volume and, hence,

    change in total costs are equivalent to VC (Rs 3,000). Accordingly, theadditional sales of Rs 5,000 has earned a contribution margin of Rs 2,000 [Rs

    5,000 (S) Rs 3,000 (VC)].

    P/V ratio = Rs 2,000 Rs 5,000 = 40 per cent.

    V/V ratio = 100 per cent 40 per cent = 60 per cent.

    Accordingly, 60 per cent of the total costs are made up of variable costs and

    the balance represents the total fixed costs (FC).

    Sales revenue = Fixed costs + Variable costs + Net profit

    Rs 95,000 = FC + 0.60 (Rs 95,000) + Rs 12,000

    Rs 95,000 = FC + Rs 57,000 + Rs 12,000Rs 95,000 Rs 69,000 = FC or Rs 26,000 = FC

    BEP (amount) = Rs 26,000 0.40 = Rs 65,000

    (Fixed expenses + Desired operating profit) P/V ratio

    In Example 2, if the desired operating profit of SV Ltd is Rs 14,000,required sales volume = (Rs 26,000 + Rs 14,000)/0.40 = Rs 1,00,000

    Additional Sales Volume Required to Offset a Reduction

    in Selling Price

    Suppose that SV Ltd reduces its selling price from Rs 10a unit to Rs 9. The sales volume needed to offset

    reduced selling price/maintain a present operating profit

    of Rs 12,000 would be:

    Desired profit (P) + Fixed expenses (FC) = Rs (12,000 + Rs 26,000)

    0.3333 = Rs 1,14,000Revised P/V ratio (Rs 3/Rs 9)

    The required sales volume of Rs 1,14,000 represents an

    increase of about 20 per cent over the present level. Themanagement should explore new avenues of sales

    potential to maintain the existing amount of profit

    Effect of Changes in Fixed Costs

    A firm may be confronted with the situation of increasing fixed costs. An

    increase in the total budgeted fixed costs of a firm may be necessitated

    either by external factors, such as, an increase in property taxes, insurancerates, factory rent, and so on, or by a managerial decision of an increase in

    salaries of executives. More important than this in the latter category are

    expansion of the present plant capacity so as to cope with additional

    demand. The increase in the requirements of fixed costs would imply the

    computation of the following:

    (a) Relative break-even points.

    (b) Required sales volume to earn the present profits.

    (c) Required sales volume to earn the same rate of profit on the proposed

    expansion programme as on the existing ones.

    The effect of the increased FCs will be to raise the BEP of the firm. Assume

    the management of SV Ltd decides a major expansion programme of its

    existing production capacity. It is estimated that it will result in extra fixed

    costs of Rs 8,000 on advertisement to boost sales volume and another Rs

    16,000 on account of new plant facility.

    Dr. Shailendra Kumar, LMTSOM, Thapar University, Patiala 16-16

    (a) The relative BEPs will be:

    Present facilities = Fixed costs P/V ratio = Rs 26,000/0.40 = Rs

    65,000.

    Proposed facilities = (Present FCs + Additional FCs) P/V ratio.

    = (Rs 26,000 + Rs 24,000)/0.40 = Rs 125,000.

    It may be noted that increase in FCs (from Rs 26,000 to Rs 50,000)

    has caused disproportionate increase in the BEP (from Rs 65,000 to

    Rs 1,25,000).(b) The required sales volume to earn the present profit

    [Present FCs + Additional FCs + Present profit (NI)] P/V ratio.

    = [Rs 26,000 + Rs 24,000 + Rs 12,000] 0.40 = Rs 1,55,000.

    (c) The required sales volume to earn the present rate of profit oninvestment:

    (Present FCs + Additional FCs + Present return on investment +

    Return on new investment) P/V ratio.

    Dr. Shailendra Kumar, LMTSOM, Thapar University, Patiala 16-17

    Let us assume that the present investment is Rs 1,00,000 and the newinvestment will involve an additional financial outlay of Rs 60,000. Therequired sales volume will be (Rs 26,000 + Rs 24,000 + Rs 12,000+ Rs 7,200(0.12 Rs 60,000)/0.40 = Rs 1,73,000.

    These computations may be reported in a summary form to the managementas follows (Table 1).

    Effect of Changes in Variable Costs

    Assuming an increase of VC by Re 1 a unit for SVLtd, the new contributionmargin will be: Rs 3 (Rs 10 Rs 7) and the revised P/V ratio 0.30 that is, (Rs 3 Rs 10).

    Revised BEP = (Rs 26,000)/0.30 = Rs 86,667

    Desired sales volume to earn existing profit = Rs 38,000/0.30 = Rs 1,26,667

    Assuming that variable costs of SVLtd decline by Re 1 per unit, revised BEP= Rs 26,000/0.50 = Rs 52,000.

    Desired sales volume to maintain existing profit = Rs 38,000/0.50 = Rs 76,000.

    Effects of Multiple Changes

    So far we have assumed that a change takes place in one of the threevariable affecting profitscost, price and sales volume. In cases where morethan one factor is affected, the BEP analysis can be applied as shown below:

    product (X from 50 to 30 per cent), the company can increase its overallprofitability. In fact, it can further augment its total profits, if it can make, andthe market can absorb, more quantities of Y and Z, say Rs 1 lakh each (Table3).

    From the above, it can be generalised that, other things being equal,management should stress products with higher contribution margins. For

    individual product line income statements, fixed costs should not beallocated or apportioned.

    2(a) Break-Even ChartThe break-even chart is a graphic presentation of the relationship between

    costs, profits, and sales. It shows not only the break-even sales but alsothe estimated costs and profit at various levels of the sales revenue. It is,therefore, also referred to as volume-cost-profit (VCP) graph/chart

    Assumptions Regarding the VCP Graph are

    1. Costs can be bifurcated into variable and fixed components.

    2. Fixed costs will remain constant during the relevant volume range ofgraph.

    3. Variable cost per unit will remain constant during the relevant volumerange of graph.

    4. Selling price per unit will remain constant irrespective of the quantitysold within the relevant range of the graph.

    5. In the case of multi-product companies, in addition to the above fourassumptions, it is assumed that the sales-mix remains constant.

    6. Finally, production and sales volumes are equal.

    1. Select an appropriate scale for sales volume on the horizontal axis, say, 2,000 units

    (Rs 20,000) per square, and plot the point for total sales revenues at relevantvolume: 6,000 units Rs 10 = Rs 60,000. Draw the sales line from the origin to Rs2,00,000 (the upper limit of the relevant range). Ensure that all the points, 0, Rs60,000 and Rs 2,00,000 fall in the same line. This should be ensured for the totalcost line also.

    2. Select an appropriate scale for costs and sales revenues on the vertical axis, say,Rs 10,000 per square. Draw the line showing Rs 60,000 fixed cost parallel to thehorizontal axis.

    3. Determine the variable portion of costs at two volumes of scales (beginning andending): 6,000 units Rs 5 = Rs 30,000; 20,000 units Rs 5 = Rs 1,00,000.

    4. Variable costs are to be added to fixed costs (Rs 30,000 + Rs 60,000 = Rs 90,000).Plot the point at 6,000 units sales volume and Rs 1,00,000 + Rs 60,000 = Rs1,60,000. Point is to be plotted at 20,000 units sales volume. This obviously is thetotal cost line.

    5. The point of intersection of the total cost line and sales line is the BEP. To the rightof BEP, there is a profit area and to the left of it, there is a loss area.

    6. Verification: FC CM per unit = Rs 60,000 Rs 5 per unit = 12,000 units or Rs1,20,000

    Figure 1 has been drawn using different scales for the horizontal andvertical axis. Figure 2 has been drawn on a uniform scale for both axes.Since the scales are the same, the 45 line will always be the proxy of thesales line. Any amount of sales revenue on the horizontal axis willcorrespond to costs and revenue on the vertical axis. Let us illustrate

    taking two sales levels.

    1. Rs 60,000: FC = Rs 60,000

    VC = 30,000 (50 per cent variable cost to volume ratio)

    TC = 90,000

    Loss = 30,000 (TC, Rs 90,000 Rs 30,000, sales revenue)

    Thus, Rs 60,000 = Rs 60,000 + Rs 30,000 Rs 30,000. Point A in Figure 2clearly shows these three relevant figures at the sales volume of Rs 60,000.

    2. Rs 1,80,000: FC = Rs 60,000

    VC = 90,000

    TC = 1,50,000

    Profit = 30,000

    Thus, Rs 1,80,000 = Rs 60,000 (FC) + Rs 90,000 (VC) + Rs 30,000 (Profit).Point B in Figure 2 portrays these three relevant figures at the sales volumeof Rs 1,80,000.

    The VCP graph in Figure 3 is drawn with the details of the individual segmentof variable cost and is more informative. The steps involved in drawing thegraph include an additional step of adding variable costs to the fixed cost.

    This is to be repeated four times for four different components: material,

    labour, direct expenses and selling expenses. In fact, fixed costs can also befurther split-up into parts. Such a graph provides a birds-eye view of theentire cost structure to the management. By drawing a line perpendicularfrom any volume (horizontal axis), the corresponding cost and profitvariables can be ascertained on the vertical axis.

    For instance, at 20,000 unit level, following are the various cost figures, asshown by the VCP graph (line A).

    The VCP graph can be modified to show the changes in the

    profitability factors of Example 4, such as,

    1.Change in fixed costs (Rs 10,000 both ways)

    2.Change in variable costs (20 per cent both ways)

    3.Change in selling price (25 per cent both ways).

    Table 4 provides a summary of the results due to the above changes.

    Only one change is taken at a point of time.

    Important Points Regarding Figure 6

    In Figures 4 and 5, there are two cost lines to show the increase and

    decrease. But Figure 6, which is designed to reveal the change due to the

    selling price, has only one sales line (45). The impact of change in the

    sales price is reflected indirectly in the variable cost line (which is merged

    with FC line and is represented by the total cost line). This is due to the fact

    that the V/V ratio which is an essential input for drawing the chart gets

    changed when the selling price is changed. In other words, Figure 6 is like

    Figure 5. The new V/V ratio has been determined as follows.

    (1) When there is an increase in selling price by 25 per cent

    Sales price ( revised) = Rs 5.50 (Rs 10 + 25 per cent) or 125 per cent (Rs 12.5

    per unit).

    Variable costs = Rs 5 or 50 per cent (existing).

    V/V Ratio = (Rs 5 Rs 12.50) or (50 125) or 40 per cent.

  • 8/2/2019 Mang Account

    37/40

    Dr. Shailendra Kumar, LMTSOM, Thapar University, Patiala 16-37

    (2) When there is a decrease in sales price by 25 per centSales price= Rs 7.50 (Rs 10 Rs 2.50) or 75 per cent (Rs 7.5 per unit).

    Variable costs= Rs 5 or 50 pr cent (existing).

    V/V Ratio= (Rs 5 Rs 7.50) or (50 75) or 66.67 per cent .

    Total cost line= Rs 60,000 + 66.67 per cent sales.

    Since the V/V ratio assumes a fractional form, care has been taken to plot

    points at sales levels of Rs 1,50,000 and Rs 2,40,000 so that corresponding

    variable cost figures can be whole numbers, that is, Rs 1,00,000 and Rs

    1,60,000 respectively.

    Figure 7 portrays VCP relationships of a sales-mix for multi-product firm

    (Example 3).

    Cash Break-Even Point

    The VCP relationship can also be used to show the liquidity position of the

    firm. This is done through the computation of cash break-even point or

    cash break-even sales revenue (CBEP/CBESR). Algebraically:

    CBEP =Total cash fixed cost (CFC)

    Equation 1Contribution margin per unit

    CBESR =Total cash fixed cost

    Equation 2

    P/V ratioGraphically, the CBEP is determined at the point of intersection of total

    cash cost line and total sales line. The area to the left of the curve

    signifies cash losses and the area on the right side is indicative of cash

    profits.

    Assuming for Example 4, the cash fixed cost to be Rs 15,000, the CBESRusing Equation 2 would be Rs 30,000 = Rs 15,000 0.50

    Figure 8 portrays the graphic presentation of the cash break-even sales

    revenue.
