Calculate Price Percentages Now! →The Basics of Percentage Calculation
At its core, a percentage is a way of expressing a number as a fraction of 100. The word "percent" literally means "per hundred." So, 20% simply means 20 out of every 100.
The fundamental formula for calculating a percentage is:
Percentage = (Part / Whole) × 100
Common Price-Related Percentage Calculations
Here are some common scenarios where understanding percentages in price is essential:
- Calculating Discounts: Finding the sale price after a discount.
- Calculating Sales Tax: Determining the final price including sales tax.
- Calculating Price Increases: Understanding the percentage increase in the price of goods or services.
- Finding Percentage Difference in Prices: Comparing the prices of two similar products and seeing the increase or decrease
How to Calculate Discount Percentage
Discounts are usually offered as a percentage of the original price. To calculate the sale price after a discount:
- Calculate the Discount Amount: Multiply the original price by the discount percentage (expressed as a decimal).
- Subtract the Discount Amount: Subtract the discount amount from the original price.
Example: A shirt costs $50, and it's 20% off.
- Discount Amount: $50 * 0.20 = $10
- Sale Price: $50 - $10 = $40
Therefore, the sale price of the shirt is $40. If this seems like too much work, use our percentage calculator at the top of the page!
Calculating Sales Tax
Sales tax is added to the original price. To calculate the final price including sales tax:
- Calculate the Tax Amount: Multiply the original price by the sales tax percentage (expressed as a decimal).
- Add the Tax Amount: Add the tax amount to the original price.
Example: An item costs $100, and the sales tax is 6%.
- Tax Amount: $100 * 0.06 = $6
- Final Price: $100 + $6 = $106
Therefore, the final price including sales tax is $106. Our percentage calculator makes short work of these types of calculations!
Calculating Percentage Change in Price
Percentage change is used to determine the extent that a price increases or decreases. The formula is:
Percentage Change = ((New Price - Original Price) / Original Price) × 100
Example: A product's price increased from $20 to $25.
Percentage Change = (($25 - $20) / $20) × 100 = 25%
Therefore, the price increased by 25%. You can also use our calculator to quickly calculate percentage increase or calculate percentage change between two numbers.
