A holiday promotion on Amazon costs you four things per unit: the discount you fund, the variable promotion fee on each sale, a share of the upfront fee spread across the units sold, and the lower margin on a product whose fulfillment fee did not go down with the price. Partly offsetting that, the referral fee shrinks because it is charged on a lower price. On the $49.99 example below, a 25 percent off Black Friday deal costs $11.52 per unit net, and the deal has to sell about 3.2 times the units the product would have sold at full price over the same days just to earn the same contribution.
Amazon published its holiday terms in a Seller Central news post titled "Holiday 2026: Same fees, same eligibility, earlier deadlines" in July 2026. For Best Deals, Lightning Deals, and Prime Exclusive Price Discounts running in Black Friday Week and Cyber Monday, the fees match Prime Day:
The same post set the deal submission window for Black Friday Week and Cyber Monday as July 8 to October 20, with a $50 discount on the upfront fee for deals submitted by September 5. As of this writing both dates have passed, so anything submitted now is outside the window, and the fee on accepted deals is the full $100.
Coupons follow a different schedule. Amazon's Coupon fees help page in Seller Central lists a $5 flat fee per coupon created plus a variable fee of 2.5 percent of sales on redeemed coupons, with the variable fee capped at $2,000. Amazon's March 2025 announcement of that structure said coupons on Prime Day 2025 would carry the same fee as on non-peak days, and the Holiday 2026 post lists no separate coupon fee for the event.
Neither fee includes the discount itself. The discount is funded by you, either through the deal price or the coupon budget.
Illustrative numbers. Take a seller with a Home and Kitchen product at $49.99. Home and Kitchen carries a 15 percent referral fee on sell.amazon.com/pricing. The per-unit costs, illustrative except the referral rate:
At full price, contribution per unit is $49.99 times 0.85, or $42.49, minus $25.70 of dollar costs: $16.79.
The seller runs a Black Friday Week deal at $37.49 and expects 300 units.
Contribution per deal unit: $16.79 minus $11.52 equals $5.27.
The deal earns $5.27 per unit against $16.79 at full price. To match the contribution the product would have earned at full price over the same days, it has to sell $16.79 divided by $5.27, or about 3.2 times as many units. If the SKU normally sells 90 units across those days, the 300-unit forecast is just enough. If the deal sells 200, it loses money compared with doing nothing.
Same product, a $10 coupon instead, with 250 redemptions. This example applies the 2.5 percent to the price the customer paid after the coupon, $39.99. Check how the Coupon fees page defines coupon sales before you rely on that.
Contribution per coupon unit: $16.79 minus $9.52 equals $7.27. The breakeven multiple is $16.79 divided by $7.27, about 2.3 times normal volume.
The coupon is cheaper per unit because the discount is smaller and the upfront fee is trivial. The deal buys placement on deal pages, which a coupon does not. Whether that placement brings 3.2 times normal volume is a question your past deals can answer, if you kept their numbers.
A lower price does not move a product into a cheaper fulfillment tier. Fulfillment fees are set by size and weight. Amazon's holiday post states peak fulfillment fees run from October 15, 2026 to January 14, 2027, at an average increase of $0.32 per unit over non-peak rates, with the 3.5 percent fuel and logistics surcharge on top. So a deal in late November pays a higher fulfillment fee on a lower price. That is already inside the $7.20 above; if your model still uses the September fee, your contribution is overstated.
Amazon's 2026 extended holiday returns policy, announced on Seller Central in October 2026, allows items purchased between November 1 and December 31, 2026 to be returned until January 31, 2027. A deal's return cost arrives in January settlements, well after the recap.
The $5,000 cap on the deal variable fee only binds once promotional sales exceed $333,333 on a single promotion. The $2,000 coupon cap binds above $80,000 in coupon sales. For most SKUs, the full percentage applies.
The discount appears against the order as a promotional rebate. The referral fee is calculated per order on the price paid. The upfront deal fee is charged per promotion, not per order, so it has no order line to ride on. Unless your bookkeeping assigns that fee to the SKU that ran the deal, it lands in a general advertising or promotions account, and the SKU's margin report looks better than it was.
ConnectBooks reconciles the transactions, fees, and returns in each Amazon settlement, promotional rebates included, and syncs them to QuickBooks or Xero as summarized entries or item-level detail. SKU-level profit reporting then shows what each product netted. For a line-by-line reading of where each charge appears, see Amazon settlement reports explained.
The breakeven multiple is only useful if you know what multiple your deals achieved. Pull last year's Black Friday Week for each SKU that ran a deal and set three numbers side by side: units sold during the deal days, units sold on the same weekdays in the two weeks before, and contribution per unit during the deal after every fee and refund that eventually posted. A deal that sold 2.4 times normal volume at a 3.2 breakeven lost money even if the revenue chart looked like a mountain.
Do the same for coupons. The $5 upfront fee only matters at low redemption counts: at 20 redemptions it adds $0.25 a unit, at 250 it adds $0.02. Past that point the 2.5 percent variable fee is the one that moves the result.
Run the numbers per unit before you commit, not per promotion afterward. Four inputs decide it: your full-price contribution, the net promotion cost per unit, the units you expect, and the units you would have sold anyway. The first two come from your books. The last two are estimates, and the gap between them is the only thing that pays for the promotion.
If the deal price falls below the SKU's breakeven floor, no volume rescues it, because every extra unit adds to the loss. Work that floor out first; the method is in setting a Black Friday discount floor for every SKU.
