FutureStarrHow to Subtract Percentage From Dollar Amount .
So I'm sending my mom a birthday present and she wants to pay me back. Can she just send the cash instead of me having to wait six weeks for it?
Let’s enter a thought bubble and attempt to mentally process this with ideas and concepts we may already be familiar with. If we think about the meaning of the word percent, which we touched on earlier, we can use the fact that they are parts of a whole to help us understand what the calculators might be doing. For instance, 25% is 25 (the “part”) out of 100 (the “whole” in this case). We can also take advantage of the fact that we know 200 is 2 times 100. So, if 25% of 100 is 25, then 25% of 200, in theory should be 2 time that value or 2 x 25, which is 50.But with values like that of which are in our initial problem statement (e.g., 25%) or even more complicated percentages, most people lose their arithmetic skills. If you are one of them, don’t worry, we’ll help you with the calculation. You can either use our percentage surcharge and discount calculators to calculate the decrease or increase in values, or you can learn how the calculation works by reading through our cohesive formulas and extensive explanations under the calculator.
Before tackling our main problem, let’s look at a simpler case. 200 is 100% more than what value? 200 is twice as much as 100, so 100% more. So, the answer is 100. If it is still a bit confusing, feel free to use our “find the base value” percentage calculator, or read through our formulas and explanations to understand the workings behind said calculations.

Do not use calculations for anything where loss of life, money, property, etc could result from inaccurate calculations.The percentage work with steps shows the complete step-by-step calculation for finding $X$ percent of $Y$ with the percent $X=10$ and the base $Y=500$. For any other combinations of the percent $X$ and the base $Y$, just supply values of the percent and the base and click on the "GENERATE WORK" button. The grade school students may use this percentage calculator to generate the work, calculate the percentage of marks, represent numbers as percents, verify the results or do their homework problems efficiently.

A percent may be greater than $100\%$ or less than $1\%$. Whole numbers are the special types of percents that are greater than $100\%$. For example, the number $5$, in terms of percent is $500\%$. Percents larger than $100\%$ can be transformed to decimals by the same procedure as ordinary percents. For example, $325\%$ is equivalent to $3.25$. A fractional percent represents a percent less than $1\%$. In this case, it is easier to find $1$ percent of the number and then find the fractional part. When comparing two values with each other, one is often interested in the percentage difference between the numbers. So, for example, if you want to determine whether there are 30% more men than women in a company, or whether this year, 28% less people went to the federal election than last year. Another real-world example could be shoe size comparisons. For instance, going from a women’s shoe size of US 7 to US 8, understanding that there is a 0.25 inch different between said shoe sizes, and wanting to know what percent this difference corresponds to.
To perform addition or subtraction on percentages, simply assume they are whole numbers. The result will be the same. However, in order to perform multiplication or division, you first must convert the percentages into decimals by dividing them by 100. Then, you can perform the operation. The result should then be multiplied by 100 to achieve the final percent value. If your calculator does not have a percent key and you want to add a percentage to a number multiply that number by 1 plus the percentage fraction. For example 25000+9% = 25000 x 1.09 = 27250. To subtract 9 percent multiply the number by 1 minus the percentage fraction. Example: 25000 - 9% = 25000 x 0.91 = 22750. (Source: www.alcula.com)
