Calculate Discounts Now! →Understanding "Percent Off"
The terms "percent off" and "discount" are essentially the same thing. When you see a sign that says "30% off," it means the original price is reduced by 30 percent.
The Formula for Calculating "Percent Off"
Calculating the "percent off" involves figuring out the amount of the discount and then subtracting it from the original price. Here's the breakdown:
- Determine the original price: This is the price of the item before any discount is applied.
- Identify the percentage discount: This is the percentage by which the original price is reduced.
- Calculate the dollar amount of the savings (Discount): Multiple the original price by the percentage.
- Calculate the final price: Subtract the discount from the original price.
Mathematically, this can be represented as:
Final Price = Original Price - (Original Price × Discount Percentage)
Step-by-Step Examples
Let's walk through a couple of examples:
Example 1
A television is listed for $800, and it's 25% off.
- Original Price: $800
- Discount Percentage: 25%
- Discount: $800 * 0.25 = $200
- Final Price: $800 - $200 = $600
Therefore, the final price of the television after the discount is $600.
Example 2
A jacket originally costs $120 and is marked down by 40%.
- Original Price: $120
- Discount Percentage: 40%
- Discount: $120 * 0.40 = $48
- Final Price: $120 - $48 = $72
So, the sale price of the jacket is $72.
Alternative Methods for Calculating Percent Off
- The "Remaining Percentage" Method: Instead of calculating the discount and then subtracting, find the percentage of the original price you *will* be paying. For instance, if an item is 30% off, you'll pay 70% of the original price. Calculate 70% of the original price to find the final price directly.
- Estimation: Round the original price to the nearest convenient number (like a multiple of ten) and estimate the discount. This is useful for quick mental calculations. See how to calculate percentage of a number.
