Simplify Percentage Addition Now →Understanding Percentage Basics
Before we dive into adding percentages, let's quickly recap what a percentage represents. A percentage is simply a way of expressing a number as a fraction of 100. For instance, 25% is equivalent to 25/100 or 0.25. This understanding is essential for performing any percentage calculation.
The Correct Way to Add Percentage Increases
The most common scenario isn't directly adding percentages together, but rather applying multiple percentage increases (or decreases) to a single value. In these cases, you can't just add the percentages; you need to apply them sequentially.
Here's the breakdown:
- Convert each percentage to a decimal: Divide each percentage by 100.
- Calculate the increase (or decrease) for the first percentage: Multiply the original value by the decimal. Add the result to the original value to get the intermediate value. For a decrease, you would subtract instead of add.
- Repeat for subsequent percentages: Use the intermediate value from the previous step as your new original value and repeat the process.
Example: Suppose you have \$100 and want to apply a 10% increase followed by a 20% increase.
- 10% converted to decimal = 0.10
- Increase by 10%: \$100 + (0.10 * \$100) = \$110
- 20% converted to decimal = 0.20
- Increase \$110 by 20%: \$110 + (0.20 * \$110) = \$132
- The final value is \$132. Note that simply adding 10% and 20% (30%) and applying it to \$100 would give you \$130, which is incorrect.
You can also achieve the same result by multiplying by (1 + percentage decimal) for each increase: \$100 * 1.10 * 1.20 = \$132
When Can You Directly Add Percentages?
You can directly add percentages when they are applied to the same base value. For instance, if you want to calculate the total percentage of your budget spent on food and transportation, and food accounts for 20% and transportation accounts for 15% of your *total* budget, then you can safely say that 35% of your budget is spent on these categories.
