Solution 12223: Calculating Mark-Up, Gross Profit Margin, and Percent Change on the TI-5018.
How do I calculate the Mark-Up, Gross Profit Margin, and Percent Change on the TI-5018?
The examples below will demonstrate using the Mark-Up key for calculations of mark-up, margin-up (or Gross Profit Margin), and percent change.
Example: Using [MU] for Mark-Up:
An item costing $355 needs to sell at a 16% profit. What is the selling price of the item, and how much profit will be made?
Before beginning the calculation:
Set the ROUND switch to 5/4.
Set the GT switch to OFF.
Set the DECIMAL switch to 2.
Press [ON/C].
• Input the value 355, press the [x] key.
• Input 16, then press [MU].
This calculates the selling price of the item, which is $411.80.
• Press the [MU] key again.
This calculates the amount of profit, $56.80.
Example: Using the [MU] key for Margin-Up or Gross Profit Margin:
Using a cost of $355 and a profit of 16% , calculate the selling price and profit as a margin calculation.
• Input the value 355, then press the [Division] key.
• Input 16, then press [MU].
This calculates the selling price, which is $422.62.
• Press the [MU] key again.
This calculates the profit, $67.62.
Example: Percent Change or Delta Percent Using the [MU] key:
What is the percent change between an original price of $140 and an increased price of $175?
• Input 175, [-], 140.
• Press the [MU] key.
This calculates the percent change, 25%.
• Press the [MU] key again.
This calculates the price difference, which is $35.
What is the percent change between an original price of $175 and a discounted price of $140?
• Input 140, [-], 175.
• Press the [MU] key.
The percent change is -20%.
• Press the [MU] key again.
The price difference (discounted) is $35.
