The BREAK-EVEN CHART is a graphical
representation showing the relationship
among the TOTAL REVENUE (R), TOTAL COST
(Yc), and FIXED COST (FC) equations.
SOME IMPORTANT FEATURES IN THE BREAK-EVEN
ANALYSIS ARE THE FOLLOWING:
1. The FIXED COST LINE (FC) is parallel to the x-axis (hence, the
slope is zero) with y-intercept equal to the FIXED COST. Fixed costs
include all indirect costs and these exist regardless of whether
production takes place or not. These include overhead expenses
such as RENT, SALARIES OF PERSONNEL or ADMINISTRATIVE
SALARIES, PROPERTY TAXES, UTILITIES, INSURANCE, INTEREST ON
BORROWED CAPITAL, MAINTENANCE and DEPRECIATION OF OFFICE
EQUIPTMENT and MACHINERY. The fixed cost equation is Y= FC.

The TOTAL COST LINE slopes upward to the
right ( slope is positive) with its y-intercept
equal to the fixed cost. The total cost for
the production of a particular commodity in
a specified period of time has two distinct
components: FIXED COST and VARIABLE COST.
VARIABLE COSTS are directly proportional to the level of
production, that is, variable costs increase as quantity of
production increases. These include expenses for WAGES
or direct labor, raw materials and all others directly
related to the production or manufacturing process.
![Page 12: Calculus.application in Business Supply Demand Break Even Anal Graph](https://reader036.fdocuments.net/reader036/viewer/2022081801/5695d3061a28ab9b029c91b4/html5/thumbnails/12.jpg)
The TOTAL COST LINE equation is given by
Yc = total variable costs + fixed costs
OR
Yc = (variable cost per unit) X + fixed costs
where X pertains to the quantity of
production and Yc, to the toal cost. The
graph shows the relationship among FIXED
COST and VARIABLE COST and TOTAL COST.

The TOTAL REVENUE LINE has a positive slope
and always passes through the origin (0,0)
since NO OUTPUT or NO SALES means NO
INCOME or NO REVENUE. The total revenue
equation can be stated as:
R= (selling price per unit) X
where X is the quantity of commodity

Based from the figure, there is a point A where the REVENUE LINE intersects the FIXED COST LINE or where R=FC. Thus, solving the REVENUE and FIXED COST equations simultaneously will yield the value of X where revenue is just enough to recover fixed costs.
There is also a point in the graph where R=Yc. Thus, solving the revenue and total cost equations simultaneously will yield the value of x necessary for the producer to earn just enough revenue to recover total costs, or to BREAK-EVEN. This X value is called the BREAK-EVEN quantity and the corresponding y-value either in the total revenue or total cost equation is the BREAK-EVEN PRICE. These X and Y values are the coordinates of the BREAK-EVEN point.
![Page 18: Calculus.application in Business Supply Demand Break Even Anal Graph](https://reader036.fdocuments.net/reader036/viewer/2022081801/5695d3061a28ab9b029c91b4/html5/thumbnails/18.jpg)
In the region to the left of BREAK-EVEN POINT, Yc>R, is the LOSS and LOSS= Yc-R.
To the right of BREAK-EVEN POINT is R>Yc, is the PROFIT. PROFIT = R-Yc.
The BREAK-EVEN analysis also includes the concept of CONTRIBUTION MARGIN, C.M. is the difference between the SELLING PRICE PER UNIT and the VARIABLE COST PER UNIT.
Therefore, C.M. (in pesos) = S.P. per unit- V.C. per unit
To express C.M. as a percentage of the selling price per unit: (C.M. in %)(S.P. per unit)= S.P. per unit – V.C. per unit
C.M. in % =[(S.P. per unit-V.C. per unit)/(S.P. per unit)] (100%)
CONTRIBUTION MARGIN is also known as MARK-UP or GROSS PROFIT.
![Page 19: Calculus.application in Business Supply Demand Break Even Anal Graph](https://reader036.fdocuments.net/reader036/viewer/2022081801/5695d3061a28ab9b029c91b4/html5/thumbnails/19.jpg)
Another method to find the x and y
coordinates of BREAK-EVEN POINT is as
follows:
At the BREAK-EVEN POINT,
R= Yc
(S.P. per unit)x= (V.C. per unit)x+FC
(S.P. per unit- V.C. per unit)x= FC
(Contribution Margin in pesos)x=FC
OR
X or BEP per unit=FC/c.m. in pesos
![Page 20: Calculus.application in Business Supply Demand Break Even Anal Graph](https://reader036.fdocuments.net/reader036/viewer/2022081801/5695d3061a28ab9b029c91b4/html5/thumbnails/20.jpg)
The Y-coordinate of the BREAK-EVEN POINT,
or the BREAK-EVEN PRICE can be determined
from the preceding formula:
X= FC/ (C.M. in pesos)
X=FC/ (C.M. in %)(S.P. per unit)
X (S.P. per unit) = FC/ (C.M. in %)
THEREFORE, Y or BEP = FC/ (C.M. in %)
![Page 21: Calculus.application in Business Supply Demand Break Even Anal Graph](https://reader036.fdocuments.net/reader036/viewer/2022081801/5695d3061a28ab9b029c91b4/html5/thumbnails/21.jpg)
The production levels to attain the desired profit, both in units and in pesos, can be obtained by using the contribution margin method.
P= R-Yc
P= (S.P. per unit)X-[(V.C. per unit)X+FC]
P= [(S.P. per unit)X-(V.C. per unit)X]-FC
P+FC=(S.P. per unit- V.C. per unit)X
P+FC=(C.M. in pesos)X
Finally, X= (P+FC)/ (C.M. in pesos)
Where X is the sales volume or production level in units to attain profit.
PESO sales volume to attain P= (P+FC)/ C.M. in %
