Max: 99%
Integer: Yes (no fractional percentages)

Discount Fixed Amount:

Min: $0.01
Max: $1,000.00

7. COMPLEX CALCULATIONS

7.1 Order Total Calculation

Formula:

subtotal = SUM(item.price for item in cart.items)

discount_amount = 0
IF discount_code IS NOT NULL THEN
  IF discount_code.discount_type == "percentage" THEN
    discount_amount = subtotal * (discount_code.discount_value / 100)
    IF discount_code.maximum_discount_amount IS NOT NULL THEN
      discount_amount = MIN(discount_amount, discount_code.maximum_discount_amount)
    END IF
  ELSE IF discount_code.discount_type == "fixed_amount" THEN
    discount_amount = discount_code.discount_value
  END IF
END IF

taxable_amount = subtotal - discount_amount

tax_rate = get_tax_rate(user.country, user.state)
tax_amount = taxable_amount * tax_rate

total = subtotal - discount_amount + tax_amount

ROUND(total, 2)  // Round to 2 decimals

Example:

Item 1:           $29.99
Item 2:           $49.99
Subtotal:         $79.98

Discount (20%):   -$16.00
Taxable:          $63.98

Tax (10%):        +$6.40
Total:            $70.38

7.2 Seller Payout Calculation

Formula:

order_total = $100.00

platform_commission_rate = 0.15  // 15% for creators
platform_commission = order_total * platform_commission_rate
= $100.00 * 0.15 = $15.00

payment_processing_fee = (order_total * 0.029) + 0.30
= ($100.00 * 0.029) + $0.30 = $3.20

seller_payout = order_total - platform_commission - payment_processing_fee
= $100.00 - $15.00 - $3.20 = $81.80

Example:

Order total:              $100.00
Platform commission (15%): -$15.00
Payment processing (2.9% + $0.30): -$3.20
Seller receives:          $81.80

7.3 Streaming Royalty Calculation

Formula:

monthly_subscription_revenue = $100,000
total_plays_this_month = 10,000,000

per_play_rate = monthly_subscription_revenue / total_plays_this_month
= $100,000 / 10,000,000 = $0.01 per play

track_plays = 50,000
track_royalty = track_plays * per_play_rate
= 50,000 * $0.01 = $500.00

creator_share = 0.70  // 70% to creator, 30% platform
creator_payout = track_royalty * creator_share
= $500.00 * 0.70 = $350.00

Minimum Payout:

IF creator_balance >= $50.00 THEN
  process_payout(creator_id, creator_balance)
ELSE
  hold_until_minimum_reached()
END IF

7.4 Tax Calculation

US Sales Tax (varies by state):

state_tax_rates = {
  "CA": 0.0725,  // California: 7.25%
  "TX": 0.0625,  // Texas: 6.25%
  "NY": 0.04,    // New York: 4%
  "FL": 0.06,    // Florida: 6%
  // ... other states
}

tax_amount = subtotal * state_tax_rates[buyer.state]

EU VAT (value-added tax):

country_vat_rates = {
  "DE": 0.19,  // Germany: 19%
  "FR": 0.20,  // France: 20%
  "UK": 0.20,  // UK: 20%
  "ES": 0.21,  // Spain: 21%
  // ... other countries
}

IF buyer.has_valid_vat_number THEN
  // Reverse charge (B2B)
  vat_amount = 0
ELSE
  // Standard VAT (B2C)
  vat_amount = subtotal * country_vat_rates[buyer.country]
END IF
