📖 How to Use This Calculator
Get Accurate ROI Data Before Every Promotion
Follow these 6 steps to make sure your numbers are real, not optimistic guesses before you spend a single dollar on promos.
1
Pick Your Promo Type
Select Coupon, Lightning Deal, Prime Exclusive, BOGO, or PPC+Coupon. Each type loads different fee fields and default uplift ranges automatically.
2
Enter True Unit Economics
Use real COGS (product + inbound shipping), FBA fees from Seller Central's fee preview, and your actual average PPC cost per unit sold.
3
Set Your Discount
Drag the slider or type directly. Switch between % off and $ off. The Scenario Table at the bottom updates live so you compare all levels.
4
Be Conservative with Uplift
Coupons: 20–50%. Lightning: 200–400%. Prime Exclusive: 50–100%. Overestimating makes every bad promo look profitable on paper.
5
Check Break-Even First
Look at "Min Uplift Needed." If break-even requires 300%+ uplift for a coupon, your discount is too deep — reduce it until it's realistic.
6
Use the Scenario Table
Find the sweet spot — the highest discount that still shows positive ROI at a realistic uplift. The highlighted row shows your current setting.
💡
The $0.60 Fee Adds Up FastAmazon's clip fee is per redemption, not per sale. At 500 units × 60% redemption = $180 in hidden fees not shown in your ad dashboard.
⚡
Lightning Deals: ROI Isn't EverythingBreak-even LDs can still be worth it for BSR improvement and review velocity. Know exactly what you're paying for that ranking boost.
🎯
Target 100%+ ROI for CouponsBelow 50% ROI means you're paying too much per incremental sale. Reduce the discount, cut ad spend, or improve your price point.
📊
Duration Matters More Than %A 10% coupon for 30 days with 150 units/month costs far more than 7 days. Always compare "Total Promo Cost" vs your monthly profit baseline.
