Break-Even Analysis
An important part of running a company is the determination of how the company should be financed and how the prices of the products the company sells should be set.
Clearly, in order to do this properly a sound financial analysis is necessary.
![Page 4: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/4.jpg)
Types of costs
It is essential to realize that there are two basic types of costs a company incurs.
• Variable Costs• Fixed Costs
Variable costs are roughly proportional to a company’s sales. I.e. the cost per unit remains roughly constant.
Fixed costs remain roughly the same regardless of sales. I.e. the cost per unit is inversely proportional to sales.

Break-Even Analysis
Commonly, the Break-even point is defined to be the level of sales where:
Revenues = Expenses
Let us have a look at a simple example.
Aunt Petunia opens a flower shop.
![Page 7: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/7.jpg)
Break-Even Analysis
Fixed Costs:
• Rent: 5,000• Utilities: 300• Helper: 1,500
Variable Costs:
• Flowers: 40% of selling price
So we know that: Selling price – cost of flowers – rent – utilities
– helper = 0when she breaks even

Let’s enter the last line into the spread sheet
We learned something in the last lesson. It’s good to put the assumptions separately.
=E6*$H$7But!!!?? I’m not a Mathematician!How am I going to find the value for E6 so that E11 = 0?
=E6-E7-E8-E9-E10

Piece of cake! Trial and error!
Oops! Not as easy as I thought.Especially if H7 is not a nice number like 40%. Is there a better way?

The Solver
We could cave and write down the equation. That would, in fact not be such a bad idea since equations are really not as difficult to understand when one knows what they are supposed to mean.
But *** RELIEF *** Excel has an incredibly useful function called the solver. It will solve equations without giving it the equations!
That was close ….

The Solver
The Solver can be found in the Tools menu of Excel. If it’s not there, it can be installed by going to the “Add-ins” menu item and selecting the Solver Add-in.
This is really quite self-explanatory!
Enter the appropriate values for “Set target cell”, “Equal to” and “By changing cells”, and click Solve.

Let try out the Solver!
Incredible!Like this anyone can do Math!
The break even point is 11,333
![Page 13: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/13.jpg)
An Equation
The Solver is a fabulous tool, but really in business it is beneficial to at least be open-minded about equations.
Let’s give it a try! We know that:E11=E6-E7-E8-E9-E10(Income = Sales – Cost – Rent – Utilities – Helper)
At the break even point, Net Income = 0 and hence E11 = 0
Inserting this we obtain:0 = E6-E7-E8-E9-E10
![Page 14: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/14.jpg)
An Equation
We want to change E6 such that0 = E6-E7-E8-E9-E10
is true.
Ah, if we just set E6 to the other values together the above equation is true. Or,
E6 = E7+E8+E9+E10is the solution to our problem.
Let’s try it and go back to the situation before we used the solver:

Let’s fill the equation into cell E6
Oops!
What went wrong?
=E7+E8+E9+E10
![Page 16: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/16.jpg)
An Equation
May be Math isn’t as easy as I thought…
But wait, doesn’t E7 depend on E6? Yes indeed, we have defined E7 = E6 * H7 (cost of product).
Let’s put this into our equation:
E6 = E7+E8+E9+E10 => E6 = E6*H7+E8+E9+E10
Or: E6 - E6*H7 = E8+E9+E10E6 * (1 - H7) = E8+E9+E10E6 = (E8+E9+E10) / (1 - H7)

Yosh! Let’s try that again.
Yatta! It works
After all, this was quite easy wasn’t it?And now we can change H7 to play out scenarios. Very useful indeed!
(E8+E9+E10) / (1 - H7)
![Page 18: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/18.jpg)

If Aunt Petunia raises the price so that the cost is only 30% of sales ….
… she can break even already at 9714. Of course now she may be so expensive that no one wants to buy her flowers anymore.
![Page 19: Break Even Analysis Lecture 5 This lecture is part of Chapter 2: Budgets, Running a Company](https://reader035.vdocument.in/reader035/viewer/2022081519/56649e715503460f94b6f62b/html5/thumbnails/19.jpg)
The other way around
There may be times when it is betterto turn things around.
Just now, Aunt Petunia found how much she needs to sell in order to break even given certain cost as percentage of sales. This is in general a good idea since for many products the profits are more or less set.
In order to see how feasible a business is one could also enter an expected sales amount and then see how much the cost of the product can be in order to break even.

With our nice equation, it’s fairly easy to accomplish this:
E6 * (1 - H7) = E8+E9+E10(1 – H7) = (E8+E9+E10)/E6H7 = 1 - (E8+E9+E10)/E6
Cool! And I thought that Financial Analysis is only for … others

Key Points of the Day
The Solver is a great tool
But Math can be very useful as well
There are two types of costs:
– Variable Costs
– Fixed Costs
Break Even Analysis is a snap with Excel
