SOURCE: Determine Selling Price doesn't work

The computer is not broken and is correct saying what the sales price is. If you work backwards from selling price and take 20% off, then you get 29.24. The program is a generally accepted accounting principle (GAAP) that has markup not from cost, but from retail. You have been doing it wrong all these years and have been giving your customers a better deal. Play with the numbers and you will see what I mean.

Here's how to use the MU/MD key. Say you want your item that COSTS you $120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin.

Enter: 120 X

Enter: 40 MU'MD

Result: 200.00

Proof: 200 - 120 = 80 / 200 = 40%

Essentially the same as using the COST/ SELL/ MAR keys.

The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.

I haven't used a calculator with these functions, so let's do a test.

I'm guessing is it for doing basic accounting. The equation is Sales - Costs = Gross Profit and maybe Gross Profit / Sales = Gross Margin.

If we enter 100 in sell, 40 in cost, does the margin come out to be 60 or 0.6? If it comes out to 60, the margin is the Gross Profit. If it comes out to 0.6, then the margin is Gross Margin.

Good luck,

Paul

Hi,

Let's set up a table to see it (sorry, I'm a visual learner;)

Selling Price $2.50 x

Unit Cost $1.00 $1.25

-------

Gross Profit $1.50 x - 1.25

Gross Margin 60% 60%

Time for some algebra;)

x - 1.25 0.6

---------- = -------

x 1

Now we can cross-multiply or multiply both sides by x to get rid of the fraction.

x - 1.25 = 0.6 x

Subtract 0.6x from both sides and add 1.25 to both sides to get the variables on one side and the constants on the other.

x - 0.6 x = 1.25

0.4x = 1.25

Divide both sides by 0.4 to get x by itself.

x= 1.25

------

0.4

x= 3.125

Good luck.

Your Texas Instruments calculator has a built-in printer for producing a permanent record printout of

your calculations with negative numbers printed in red. A big, easy-to-read display also enables you to

check entries or perform quick calculations without printing.

GETTING STARTED

OFF ON PRT IC GT

POWER

1. Connect the calculator to a proper power outlet (110-120V or 220-240V

where available).

2. The calculator is turned on by setting the POWER switch to the PRT

position.

Inserting the paper (see illustrations 1, 2, 3, and 4 on page ii).

1. Turn on the calculator.

2. Open the printer compartment cover by pressing down on its front edge and sliding it back in the

direction of the arrow.

3. Fit the roll of paper on the holder so that it unrolls from the bottom, with the loose end toward the

calculator.

4. Cut the end of the paper squarely and insert it firmly into the printer slot on the back of the

calculator.

5. Press & until the paper is in the printing position.

Replacing the ink roller (see illustrations 5 and 6 on page ii)

1. Turn the calculator off and tear off the excess paper.

2. Remove the printer cover by pressing down on both sides of the front edge and sliding back in the

direction of the arrow.

3. Remove the old ink roller by lifting it with the removal tab.

4. Insert the new ink roller into the compartment and press down gently until it snaps into place. Close

the printer compartment.

Note: The old ink rollers should not be refilled. Replacement rollers can be obtained from your local

retailer. The warranty does not cover ink roller replacement.

Hi,

I think you should refer to you definitions. The 20% is called the markup. The profit margin is calculated with respect to the revenue. So you should divide the 400$ by 2400$ to get a net profit margin of 400/2400 =0.1667 or 16.67% (And we are not taking into account the taxes).

Margin = Markup /(price + Markup)

Markup = Margin* (Price +Markup)

Markup = Margin*Markup + Margin* Price

Markup*(1-Margin) =Margin*Price

Markup = Margin*Price/( 1-Margin)

For Price =2000, Margin =0.2 (that is 20%)

Markup = 0.2*2000(1-0.8) =0.2*2000/0.8

Markup = 2000*(0.2/0.8)= 2000*0.25 = 500

Thus to have a (net) profit margin of 20%, an item costing 2000$ must be marked up by 500$.

Try not to reason with numbers. Write the defining relation and use algebra to isolate for the variable you seek.

Hope it helps.

Ok I looked for ages for how these keys work and once you knwo how it is quite simple.

say something costs 100, enter 100 then press the cost button

say you want a margin of 25% then enter 25% and press the mgn button the result is the selling price 133.33

So to reverse it enter 133.33 press the sell button

Enter 25% and press the mgn button

result is 99.99 cost price (100) bar a cent/penny

and finally to work out margin

enter 100 press cost button

enter 133.33 press sell button

result is 24.99 which is the percentage margin

Simple isn't it

say something costs 100, enter 100 then press the cost button

say you want a margin of 25% then enter 25% and press the mgn button the result is the selling price 133.33

So to reverse it enter 133.33 press the sell button

Enter 25% and press the mgn button

result is 99.99 cost price (100) bar a cent/penny

and finally to work out margin

enter 100 press cost button

enter 133.33 press sell button

result is 24.99 which is the percentage margin
