Key Definitions

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

  • Cost Price (CP): The original price of an item or the total expenses incurred to produce a product or carry out a service.
  • Selling Price (SP): The price at which an item is sold.
  • Profit: The difference between the selling price and the cost price (SP - CP).
  • Revenue: The total income generated from sales before any deductions.

Calculating Percentage Profit

There are two primary ways to calculate percentage profit, each giving a different perspective:

1. Profit Percentage Based on Cost Price

This method shows the percentage of profit relative to the cost price. It's useful for understanding how much you're earning on top of your initial investment.

Formula:

Profit Percentage = ((Selling Price - Cost Price) / Cost Price) * 100

Example:

Suppose you buy an item for $50 (Cost Price) and sell it for $75 (Selling Price). The profit percentage would be:

(($75 - $50) / $50) * 100 = 50%

This means you're making a 50% profit on your initial cost.

2. Profit Margin Based on Revenue

This method shows the percentage of profit relative to the revenue generated. It's valuable for understanding how much of your sales income is actual profit.

Formula:

Profit Margin = ((Selling Price - Cost Price) / Selling Price) * 100

Example:

Using the same values as above, the profit margin would be:

(($75 - $50) / $75) * 100 = 33.33%

This indicates that 33.33% of your revenue is profit.

Different Types of Costs

When you how calculate percentage profit, it's important to account for different types of costs:

  • Actual Cost: All expenses incurred in acquiring an item, including freight, duty, etc.
  • Last Cost: The actual value of the item when last purchased.
  • Average Cost: The average value of the item, calculated by combining the total value of old and new stock and dividing by the total number of units.
