RapidResell AIDiscount & pricing tier optimizer
Promotions move inventory, but every percent off comes straight out of profit. Find the deepest discount your numbers can take, and how many extra sales it needs to pay for itself.
How it's calculated
Discounts apply to the item price only. Shipping you charge the buyer is unchanged, and percentage fees are recalculated on the lower order total.
| Metric | Formula |
|---|---|
| Sale price | list price × (1 − discount) |
| Profit at a discount | (sale price + shipping charged) × (1 − fee %) − fixed fee − COGS − shipping cost − ad spend |
| Max discount before a loss | 1 − break-even price ÷ list price |
| Max discount keeping target margin m | 1 − [(fixed fee + costs) ÷ (1 − fee % − m) − shipping charged] ÷ list price |
| Extra sales needed | full-price profit ÷ discounted profit − 1 |
Reading the sales-lift column
Suppose you net $20 on an item at full price and $10 at 25% off. You need twice as many orders, a 100% sales lift, just to earn the same total profit. Discounts that need more than a 30–50% lift rarely pay off unless you're clearing stale inventory, where getting cash back beats holding the item.
Price with room to discount
The easiest way to protect margin in a sale is to start from the right list price. Check what comparable items actually sold for using our guide to sold-comp price research, then come back and plan your markdowns. You can also check a single sale in the profit & margin calculator.
RapidResell AI identifies the item from a photo, prices it against real sold comps, and publishes to eBay.
