How to Get 20 Percent of a Number

The concept of changing an entire situation by changing a single number is close to magical. It is a why-didn’t-I-think-of-that-the-first-time scenario: speaking with a prospect who is on the fence and you say, “I do a lot better than the other numbers in the industry. What’s the problem? If you trust me, then let’s move the needle and make a better decision”.


As finding 10% of a number means to divide by 10, it is common to think that to find 20% of a number you should divide by 20 etc. Remember, to find 10% of a number means dividing by 10 because 10 goes into 100 ten times. Therefore, to find 20% of a number, divide by 5 because 20 goes into 100 five times.

Learning to do basic math in your head is useful, but there are times when you need to make sure you are calculating the problem exactly. To subtract any percentage from a number, simply multiply that number by the percentage you want to remain. In other words, multiply by 100 percent minus the percentage you want to subtract, in decimal form. To subtract 20 percent, multiply by 80 percent (0.8). To subtract 30 percent, multiply the number by 70 percent (0.7). (Source: sciencing.com)


Calculate your savings from a price discount. Write down the original price and the discount percentage. Then, subtract the discount percentage from 100. For instance, if you want to buy a shirt that’s 30% off, 100% - 30% is 70%. That means you’ll pay 70% of the original price. Now you’re ready to walk through this easy calculation:

An example of using this formula to determine the difference between product costs would be the following: A product cost $25 last year and a similar product costs $30 this year. To determine the percentage difference, you would first subtract the costs from each other: 30 - 25 = 5. You would then determine the average of these two costs (25 + 30 / 2 = 27.5). You will then divide 5 by 27.5 = 0.18. You will then multiply 0.18 by 100 = 18. This means that the cost of the product from this year is 18% more than the cost of the product from last year.
