# Eighty percent off calculator

How to calculate eighty % off any number. How to figure out percentages off a price.

### Inputs

Original Price of the Item: \$
Discount Percent (% off): %

### Results

Amount Saved (Discount): \$
Sale / Discounted Price: \$ Spanish Version

Using this calculator you can find the discount value and the discounted price of an item. It is helpfull to answer questions like:

• 1) What is eighty percent (%) off \$one hundred?
• 2) How much will you pay for an item where the original price before discount is \$ one hundred when discounted eighty percent (%)? What is the final or sale price?
• 3) \$80 is what percent off \$100?
• See how to solve these questions just after the Percent-off Calculator (or Discount) below.

## how to work out discounts - Step by Step

To calculate discount it is ease by using the following equations:

• Amount Saved = Orig. Price x Discount % / 100 (a)
•
• Sale Price = Orig. Price - Amount Saved (b)

Now, let's solve the questions stated above:

### 1) What is 80 percent off \$100? Find the amount of discount.

Suppose you have a Kohls coupon of \$100 and you want to know how much you will save for an item if the discount is 80.

Solution:

Replacing the given values in formula (a) we have:

Amount Saved = Original Price x Discount in Percent / 100. So,

Amount Saved = 100 x 80 / 100
Amount Saved = 8000 / 100

In other words, a 80% discount for a item with original price of \$100 is equal to \$80 (Amount Saved).

Note that to find the amount saved, just multiply it by the percentage and divide by 100.

### 2) How much to pay for an item of \$100 when discounted 80 percent (%)? What is item's sale price?

Suppose you have a L.L. Bean coupon of \$100 and you want to know the final or sale price if the discount is 80 percent.

Using the formula (b) and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 100 - 80

This means the cost of the item to you is \$20.

You will pay \$20 for a item with original price of \$100 when discounted 80%.

In this example, if you buy an item at \$100 with 80% discount, you will pay 100 - 80 = \$20.

### 3) 80 is what percent off \$100?

Using the formula (b) and replacing given values:

Amount Saved = Original Price x Discount in Percent /100. So,

80 = 100 x Discount in Percent / 100
80 / 100 = Discount in Percent /100
100 x 80 / 100 = Discount in Percent
8000 / 100 = Discount in Percent, or

Discount in Percent = 80 (answer).
