Calculate Your Discount Now! →The Basic Formula
The core concept is simple: determine the discount amount, then subtract it from the original price.
- Calculate the Discount: Multiply the original price by the discount percentage (expressed as a decimal).
- Find the Sale Price: Subtract the discount amount from the original price.
For example, a $100 item with a 20% discount:
- Discount: $100 * 0.20 = $20
- Sale Price: $100 - $20 = $80
A Simpler Approach
Here's a streamlined method that's easy to remember:
- Determine the Percentage You'll Pay: Subtract the discount percentage from 100%.
- Multiply: Multiply the original price by the percentage you'll pay (as a decimal).
Using the same example:
- Percentage to Pay: 100% - 20% = 80%
- Sale Price: $100 * 0.80 = $80
Mental Math Tricks
Calculating percentage of a number in your head can save time and effort.
- Finding 10%: Simply move the decimal point one place to the left. For example, 10% of $150 is $15.
- Finding 5%: Halve the 10% value. In the example above, 5% of $150 is $7.50.
- Finding 15%: Add the 10% and 5% values. 15% of $150 is $15 + $7.50 = $22.50.
Handling Stackable Discounts
Sales offering "Extra % Off" can be tricky. Remember, the second discount applies to the already discounted price, not the original.
For example: Item costs $100. It's 30% off, plus an additional 20% off.
- First Discount: $100 * 0.30 = $30. Sale Price: $100 - $30 = $70.
- Second Discount: $70 * 0.20 = $14. Final Sale Price: $70 - $14 = $56.
Notice that this is different than taking 50% off. Always calculate each discount sequentially.
