How to calculate 30% discount from 150 explained

Given, you are about to purchase one or multiple products with a total price of 150 dollars (pounds, euro or any other currency). You received an offer with 30% discount off the full price of 150.

Talking about discount calculation you might have two questions:

  • What is the final price of the product after 30% discount applied to the full price of 150?
  • What is the amount saved after 30% discount applied to the full price of 150?

There are multiple approaches to calculate percent discounts:

Option 1: use the calculator above

The most easiest and convenient option is to use above calculator. Add it to the bookmarks so that you not lose it next time you need it (that is why the name of the website is ToolsFromBookmarks).

Our calculator uses algorithms listed below anyway. It might save your time and be more convenient. If you are interested in math standing behind it follow next options.

Option 2:

Let’s calculate amount saved first:

Amount you save is simply a percent of the number. To calculate percent, divide the full price by 100 and multiply by percent. In our case:

150 / 100 * 30 = 45.00

To get the discounted price, subtract amount saved from the full price:

150 – 45.00 = 105.00

Option 3:

You may first calculate what is a final percent after discount. For our example, full price is 100%, after 30% discount we will get 70% of the full price:

100% - 30% = 70%

Having the percent after discount, calculate it of the full price of 150:

150 / 100% * 70% = 105.00

There might be different variations for the options above

I.e one of the convenient ways to calculate percent is to shift floating point 2 figures left. This is what divide by 100 means, thus we find fraction of 1. For example for 50% it will be 0.5, for 25% fraction is 0.25, for 10% fraction is 0.1for one percent – 0.01 (1 / 100 = 0.01). Then, having these fractions, multiply it for the full price.

For our case of 30 percent off 150:

Discount percent: 30% => 0.3000
Fraction of 1 after discount: 1 - 0.3000 = 0.7000

Final values:

150 * 0.3000 = 45.00 – for discount amount
150 * 0.7000 = 105.00 – for final price

As far as you are comfortable with math and have an understanding of percentages, you may come up with any other combination of the options listed above
