Plan Black Friday discounts without killing your margin. Max safe discount depth, volume targets and offer comparisons for sellers.
"How deep should I go for Black Friday?" Most sellers pick a number that sounds exciting — 40% off! — and discover later that it wiped out their margin. This planner works backwards from your actual unit economics: your price, landed cost, fees and baseline volume. It tells you the deepest discount you can survive, how much extra volume each discount depth demands, and which type of offer protects your margin best.
The discount ladder is the heart of this tool. A 20% discount doesn't need 20% more sales to break even — because your profit per order shrinks, you might need double the volume. Scan the feasibility column: "Achievable" means normal sale-season traffic covers it; "Stretch" means you'll need your email list and ads firing; "Unlikely" means the discount is a vanity play that costs you money.
The offer comparison often surprises people: a free gift that costs you $4 can feel as generous as 10% off while protecting far more margin — and it never trains customers to wait for discounts. Bundles (second item half price) move twice the units per transaction, which is gold when your bottleneck is traffic, not margin. Free shipping converts browsers brilliantly, but only you know your parcel costs.
Find your 'max discount before you lose money' number above — that's your hard ceiling. Stay 5–10 points under it so unexpected costs (returns, ad spend) don't push you underwater.
It depends on your parcel cost. The offer table compares both on profit per item — for cheap-to-ship products, free shipping often wins on margin and conversion.
Sale volume comes from three places: your email/SMS list (highest ROI), retargeting ads to past visitors, and marketplace placement. Line all three up before the sale starts.
No — it models product margin per order. If you run ads, subtract your target CAC from the 'profit per order' figure to see the true picture.
