Master Percentage Change Calculations with These Simple Tips
Introduction
Calculating percentage change is a useful skill that is necessary for many fields. It comes in handy when you need to determine growth rates or calculate discounts. However, many people struggle with this concept. In this article, we will provide you with some simple tips to help you master percentage change calculations.What is Percentage Change?
Percentage change refers to the difference between two values expressed as a percentage of one of those values. The formula is (New Value - Old Value) / Old Value x 100%. To simplify it further, percentage change = (Difference / Original Value) x 100%.Types of Percentage Change
There are three types of percentage change- increase, decrease, and net change. An increase occurs when the new value is greater than the old value. A decrease occurs when the new value is less than the old value. Net change refers to the overall change, regardless of whether it's positive or negative.Example: Increase
Suppose you purchased a stock for $50 per share, and its value rose to $60 per share. The percentage increase would be: ((60-50)/50)*100 = 20%.Example: Decrease
Suppose you purchased a stock for $50 per share, and its value dropped to $40 per share. The percentage decrease would be: ((40-50)/50)*100 = -20%.Example: Net Change
Suppose you purchased a stock for $50 per share, and its value rose to $60 per share. Afterward, the value fell to $55 per share. The net percentage change would be: ((55-50)/50)*100 = 10%.Simple Tips
1. Make sure you know the formula for percentage change.2. Define the types of percentage change and understand their differences.3. Take every opportunity to practice, particularly in everyday situations like calculating your investment portfolio.Practice Makes Perfect
The more you practice, the more comfortable you will become with using percentage change in real-life situations. For example, suppose you wanted to calculate the percentage increase in your grocery expenses after moving to a different city where prices for goods vary. In that case, you would first determine the difference between the old and new grocery expenses and then use the percentage change formula.Comparison Table
| Type of Percentage Change | Formula | Example |
|---|---|---|
| Increase | (New Value - Old Value) / Old Value x 100% | ((60-50)/50)*100 = 20% |
| Decrease | (New Value - Old Value) / Old Value x 100% | ((40-50)/50)*100 = -20% |
| Net Change | (New Value - Old Value) / Old Value x 100% | ((55-50)/50)*100 = 10% |
