Generally, the way to figure out any percentage is to multiply the number of items in question, or ​X​, by the ​decimal​ form of the percent. To figure out the decimal form of a percent, simply move the decimal two places to the left. For example, the decimal form of 10 percent is 0.1. Then, to calculate what 10 percent of is, say, 250 students, simply multiply the number of students by 0.1.

The percentage increase calculator above computes an increase or decrease of a specific percentage of the input number. It basically involves converting a percent into its decimal equivalent, and either subtracting (decrease) or adding (increase) the decimal equivalent from and to 1, respectively. Multiplying the original number by this value will result in either an increase or decrease of the number by the given percent. Refer to the example below for clarification.

Calculate the total cost with sales tax. To calculate the cost of an item plus tax, start by converting the sales tax to a decimal. Next, add that number to 1 (think of 1 as 100% of the cost of the original item). For example, if sales tax is 8%, you’d do 0.08 + 1 = 1.08. Then, multiply the price of your item by 1.08. If your item costs $20, the item plus 8% tax would be $20 x 1.08, which equals $21.6.

One of the quickest ways to calculate a percentage with a calculator is to convert the percentage into a decimal and multiply it by the number you’re trying to find the percentage of. For example, if you want to find 60% of 285, enter 285 x .6 into your calculator to get 171. To figure out what percentage a number represents out of a whole, divide the smaller number by the larger one and convert the resulting decimal number into a percent. For example, 171 ÷ 285 = 0.6 = 60%. (Source: www.wikihow.com)
