Amazon Promotion & Coupon Profitability Calculator
How many additional sales does your promotion need to generate before it’s actually worth running? See whether a discount creates genuinely incremental profit, or just gives away margin on sales you may have gotten anyway.

How this is calculated
- Normal profit per unit
- Normal Price − COGS − Amazon Fees − Ad Cost − Other Variable Costs
- Promotional selling price
- Normal Price × (1 − Discount %)
- Promotional profit per unit
- Promo Price − COGS − Amazon Fees − Coupon Fee − Ad Cost − Other Variable Costs
- Baseline monthly contribution
- Normal Profit per Unit × Baseline Units
- Break-even promotional units
- Baseline Contribution ÷ Promotional Profit per Unit
- Incremental units required
- Break-Even Promotional Units − Baseline Units
This calculator never assumes a promotion will increase conversion or sales - any expected unit lift comes entirely from what you enter. It's an estimate from the numbers you provide, not a review of your actual Seller Central account or a guaranteed outcome.
