- [Instructor] In this video,
-
I'm gonna talk about
-
how we can use cost-volume-profit analysis
-
in order to reach a target net income
-
or a target profit level.
-
And what I mean by that is this.
-
So in a previous video
-
we talked about calculating
a break-even point.
-
So let's put it here, just break even.
-
But the thing is,
-
so let's say you start this business
-
that we talked about,
you start a sub shop,
-
and you go and you calculate
this break-even point
-
and you end up breaking even.
-
And then you tell your spouse,
-
"Hey, great, we broke even."
-
Well, they're gonna be upset
-
because they wanted to make money.
-
That's why you started this business.
-
You want to sell these
subs, you love subs,
-
but also you want to make money.
-
So we don't wanna just break even,
-
although that's a useful
thing to calculate
-
just to kind of see as like a floor
-
of how many sandwiches do we have to sell
-
in order to break even and not lose money.
-
But we also started this
business to make money,
-
to have a net income, to have a profit.
-
So we might say, when we
start out the business
-
and say, "Okay, well, how
much money do we make?"
-
Maybe we want a target profit,
-
or I'll just call it target net income.
-
Net income, profit, we're
talking about the same thing.
-
But let's say the target net income, NI,
-
and let's say that's $50,000.
-
Let's say that you wanna
make $50,000 a year
-
with your sandwich shop.
-
Now, I'm talking now,
-
I'm not talking about sales,
-
I'm talking about profit
-
after we've done our
revenue minus our costs
-
and what's left at the
end, the bottom line.
-
So you wanna make $50,000
as the owner of this shop,
-
but you need to know,
-
how many sandwiches do I have to sell
-
in order to make $50,000?
-
Well, just like the break-even point,
-
we need to know certain things.
-
And I've already taken the
liberty of writing 'em down here.
-
We need to know price,
-
the variable costs, contribution margin,
-
which is calculated from those two,
-
and the fixed costs, okay?
-
So, price, we're assuming
-
that we sell each sandwich for $5,
-
and then we're assuming
-
that the variable cost
associated with each sandwich,
-
the lettuce, the pickles, the bread is $3.
-
And that difference there
is our contribution margin.
-
So every sub we sell,
-
$2 is contributed toward fixed costs.
-
Or, as we're gonna find in this example,
-
that target profit figure that we want.
-
So how do we go ahead and calculate this?
-
Well, let's say first
that we want to find it.
-
Let's say we want target net income.
-
We wanna know how many units.
-
By units, we're talking about,
-
how many sub sandwiches do we have to sell
-
in order to get this?
-
So we use a formula
-
that's very similar to the
one we use for the break-even.
-
So what we're gonna have
-
is we're gonna have our fixed
costs on top in the numerator,
-
but also this time we're
gonna have something else.
-
We're gonna add in that target net income.
-
So I'm just gonna call it NI there.
-
So that's the profit that we want.
-
So the fixed cost of 20,000
-
plus the profit that we want of 50,000.
-
So let's fill in the denominator here.
-
So here we're gonna have the
contribution margin per unit,
-
and that's just that $2 figure.
-
That part is no different
-
than when we calculate the break-even.
-
So when we put this together,
-
we've got 20,000 of fixed costs.
-
Plus 50,000.
-
That's our target profit.
-
So now we not only have to
cover those fixed costs,
-
that rent and all those things
-
that don't vary with the
amount of subs we sell,
-
we not only have to cover that
-
with this contribution margin
-
that we earn on each sandwich,
-
but we also have to cover
this profit that we want.
-
Okay, and then the contribution margin
-
for our units over here is this $2.
-
Okay, so that's gonna
give us 35,000 units here.
-
I'm just gonna run out
of space a bit there.
-
So we'll say 35,000 units
or 35,000 sub sandwiches.
-
That's how many sandwiches
we have to sell.
-
Assuming these things here,
-
that we sell $5 a sub,
and these are our costs,
-
if we sell 35,000 sandwiches,
-
we can cover these fixed costs
-
and earn ourselves this
$50,000 that we wanted.
-
So, now, just like the
break-even analysis,
-
we can also say, "Well, I
don't wanna just look at it
-
"in terms of units,
-
"in terms of how many sub
sandwiches I have to sell."
-
Maybe I wanna look at it in terms of,
-
what is my sales, my bottom...
-
Or, at the end of the year
when I run up the register,
-
what is the sales,
-
what is the total sales that I had
-
for the year or the month or whatever
-
in order to get that target
net income of $50,000?
-
So we're gonna calculate that.
-
And that's also very similar
-
to the break-even point calculation.
-
So the target net income again here.
-
I'm just gonna.
-
We want $50,000 profit again.
-
But this time we want to know
-
what has to be the total sales.
-
So the numerator is gonna be the same,
-
fixed costs plus our target net income.
-
But this time at the bottom,
-
similar to the break-even analysis,
-
we're gonna have our
contribution margin ratio.
-
What is the contribution
margin ratio again?
-
Well, we're basically trying to calculate
-
how many cents of every dollar
becomes contribution margin
-
whenever we have a sale.
-
So what we do, we take this
2, we divide it by the 5,
-
and that's gonna give us 0.4.
-
That's our contribution margin ratio.
-
40 cents of every dollar of sales
-
becomes contribution margin.
-
It can be contributed
toward our fixed costs
-
and that target profit
that we have up here.
-
So we're gonna have,
again, 20,000 plus 50,000.
-
Only this time, the numerator,
-
or, excuse me, the denominator is gonna be
-
that contribution margin ratio of 0.4.
-
And we are going to
have sales of $175,000.
-
So.
-
Now, if you look at these two things,
-
they're not equivalent,
-
but they're basically
stating the same thing.
-
Because 35,000 subs, 35,000 units,
-
we say, okay, well, we
sell them at $5 a sub.
-
Well, that's gonna give us $175,000.
-
So it's basically two ways
of expressing the same thing.
-
If we have $175,000 in sales,
-
given these assumptions here,
-
we'll end up making a profit of $50,000.
