How do you calculate commissions and discounts?

If you have forgotten how to take a percent of a number, below is a brief description of how to do that followed by a video clip demonstrating the same problem.


A percentage is a fraction or ratio of a number with the denominator (the bottom number of a fraction) being 100. For example 25% is the ratio 25/100 which is equivalent to the decimal 0.25. Any percentage can be converted to a decimal by moving the decimal point two places to the left of the decimal if there is one. For example 37% or 37.0% is equivalent to 0.37 or 58.9% is equivalent to 0.589. Notice how the decimal point was moved.

Here are some examples of how to take a percent of a number.

Example A

14% of 200 

When you take a percentage of a number, it is a multiplication problem. So, you can see the multiplication problem that is created in step #2.

  1. Convert 14% to a decimal:              14% = 0.14 or .14
  2. Write out the new problem:             0.14 x 200
  3. Do the multiplication:                     0.14 x 200= 28.00 or 28


Example B

33.3% of 1,000

  1. Convert 33.3% to a decimal:             33.3% = 0.333 or .333
  2. Write out the new problem:             0.333 x 1,000
  3. Do the multiplication:                     0..333 x 1,00= 333

Below is another way of looking at the examples above.
