Key Concepts: Cost Price and Selling Price

Before diving into the calculations, let's define some essential terms:

  • Cost Price (CP): The total amount spent to acquire or produce a product or service. This includes purchase price, manufacturing costs, shipping, and any other direct expenses.
  • Selling Price (SP): The price at which you sell the product or service.

The Basic Formulas

Calculating profit and loss involves simple subtraction:

  • Profit: If your selling price is higher than your cost price, you've made a profit. The formula is: Profit = Selling Price (SP) - Cost Price (CP)
  • Loss: If your cost price is higher than your selling price, you've incurred a loss. The formula is: Loss = Cost Price (CP) - Selling Price (SP)

Calculating Profit and Loss Percentage

Knowing the actual profit or loss is helpful, but expressing it as a percentage gives you a better sense of scale and allows for easier comparison. Here's how to calculate profit and loss percentage:

  • Profit Percentage: Profit Percentage = (Profit / Cost Price) x 100
  • Loss Percentage: Loss Percentage = (Loss / Cost Price) x 100

Examples to illustrate How to Calculate Profit and Loss Percentage

Let's look at some practical examples:

  1. Example 1: Making a Profit

    You bought a vintage bicycle for $150 (CP) and sold it for $250 (SP). To calculate the profit percentage:

    • Profit = $250 - $150 = $100
    • Profit Percentage = ($100 / $150) x 100 = 66.67%

    You made a 66.67% profit on the bicycle.

  2. Example 2: Experiencing a Loss

    You bought a batch of handmade soaps for $200 (CP), but due to a change in customer preferences, you had to sell them for $120 (SP). To calculate the loss percentage:

    • Loss = $200 - $120 = $80
    • Loss Percentage = ($80 / $200) x 100 = 40%

    You incurred a 40% loss on the soaps.
