How this is calculated
Sale price: Original price × (1 − Discount%)
Profit at sale price: Sale price − Fees − Product cost − Shipping
Max discount: 1 − (Break-even price / Original price)
Extra units needed: (Full-price profit × Baseline units − Sale profit × Baseline units) / Sale profit per unit
Assumptions:
- Fees calculated on the discounted sale price
- Break-even: price where profit = 0
- Extra units based on 100-unit baseline for comparison
