Example 1: Basic Discount Calculation
Let’s say:
- Original Price: $200
- Discount: 25%
- Sales Tax: 0%
Calculation:
Discount Amount = $200 × 25% = $50
Price After Discount = $200 − $50 = $150
Final Price = $150
So, you save $50 and pay $150.
Example 2: Discount With Sales Tax
Now let’s include tax:
- Original Price: $200
- Discount: 25%
- Sales Tax: 8%
Step 1: Calculate Discount
$200 × 25% = $50
Step 2: Subtract Discount
$200 − $50 = $150
Step 3: Calculate Tax
$150 × 8% = $12
Step 4: Final Price
$150 + $12 = $162
Even though you saved $50, the final price after tax is $162.
This shows why calculating both discount and tax is important.

Understanding How Discounts Work
A discount percentage reduces the original price by a specific fraction. For example:
- 10% discount = Pay 90% of the original price
- 50% discount = Pay half the original price
- 75% discount = Pay only 25% of the original price
However, tax is usually calculated after the discount is applied. That’s why your final checkout price may be higher than expected.
