Understanding Black Friday Savings
How Discounts Are Calculated
The basic discount calculation follows this formula:
Discounted Price = Original Price × (1 - Discount Percentage / 100)
Tax is applied after discounts are calculated:
Total Price = (Discounted Price × Quantity) × (1 + Tax Rate / 100)
Example Scenarios
Example 1: Basic Discount Calculation
Scenario: $100 item with 20% discount
Discounted Price = $100 × (1 - 20/100) = $80
Total Savings = $100 - $80 = $20
Example 2: Multiple Items with Tax
Scenario: 3 × $50 items, 30% off, 8% tax
Discounted Price = $50 × 0.7 = $35
Subtotal = 3 × $35 = $105
Tax = $105 × 0.08 = $8.40
Total = $105 + $8.40 = $113.40
Example 3: 100% Discount (Free Item)
Scenario: $200 item with 100% discount
Discounted Price = $200 × 0 = $0
Total Savings = $200
Example 4: Partial Discount with Decimal Values
Scenario: $49.99 item with 15.5% discount
Discounted Price = $49.99 × 0.845 = $42.24
Savings = $49.99 - $42.24 = $7.75
Example 5: High-Quantity Purchase
Scenario: 100 × $10 items, 25% off
Discounted Price = $7.50 per item
Total Savings = 100 × ($10 - $7.50) = $250
Example 6: State Tax Variations
Scenario: $500 item, 40% off, 9.25% tax
Discounted Price = $500 × 0.6 = $300
Tax = $300 × 0.0925 = $27.75
Total = $327.75
Example 7: Progressive Discounts
Scenario: $200 item with 50%+20% off
First Discount: $200 × 0.5 = $100
Second Discount: $100 × 0.8 = $80
Total Savings = $120
Example 8: Bulk Discounts
Scenario: Buy 2 Get 1 Free ($60 each)
Original: 3 × $60 = $180
Discounted: 2 × $60 = $120
Savings = $60
Example 9: Price Match Guarantee
Scenario: $300 item found for $240 elsewhere
Effective Discount = (300-240)/300 = 20%
Savings = $60
Example 10: Seasonal Price Changes
Scenario: $150 item discounted to $90 post-Christmas
Discount Percentage = (150-90)/150 = 40%
Total Savings = $60
