Summary

In this lesson, Sandro Curió explains the concepts of profit and loss, offering practical examples to make the calculations easier to understand. He covers how to calculate profit by subtracting the cost from the selling price and how to calculate the profit percentage based on either cost or selling price. Additionally, he explains loss in a similar manner, detailing how to compute a percentage of loss relative to both the cost and selling price. Using real-life scenarios, the video helps viewers grasp these important financial concepts, providing step-by-step guidance for better comprehension.

Takeaways

• 😀 Profit is when you sell for a higher price than what you paid for the product. It’s calculated by subtracting the cost price from the selling price.
• 😀 To calculate profit percentage based on the cost price, set the cost price as 100% and use a rule of three to determine the percentage of the profit.
• 😀 When calculating profit percentage based on the selling price, the selling price becomes 100%, and you apply the same method to find the percentage of profit.
• 😀 If the selling price is greater than the cost price, you have made a profit. Conversely, if the selling price is lower, you have made a loss.
• 😀 A profit of R$100 on a product bought for R$500 and sold for R$600 equals a profit margin of 20% when calculated based on the cost price.
• 😀 The profit percentage in relation to the selling price is lower than that calculated based on the cost price. In the example above, it’s 16.6%.
• 😀 Loss occurs when the selling price is less than the cost price. A loss of R$50 can be calculated by subtracting the selling price from the cost price.
• 😀 To calculate the percentage of loss based on the cost price, the loss is compared to the cost price and then expressed as a percentage using the rule of three.
• 😀 If the percentage loss is based on the selling price, use the selling price as the reference (100%) and apply the same percentage calculation.
• 😀 In the case of a 40% profit on a product bought for R$800, the profit is R$320, and the selling price is R$1,120.
• 😀 The core idea is that profit is always calculated by subtracting the cost price from the selling price, and the loss is calculated similarly when the result is negative.
