Forecast Black Friday shipping surcharges: per-carrier peak fees, total cost hit and strategies to dodge them.
| Carrier | % of volume | Peak surcharge / pkg |
|---|---|---|
| FedEx | ||
| UPS | ||
| USPS / postal |
Defaults reflect 2026–27 published peak surcharges (FedEx ~$0.80, UPS ~$0.75). Surcharge windows typically run late September through January — update the numbers to your carrier's actual schedule.
From late September through January, major carriers add peak-season surcharges on top of normal rates — recently around $0.80 per package at FedEx and $0.75 at UPS. On hundreds of orders a month, that's real money leaking out of your margin. This planner totals your exposure from your actual carrier mix and shows four concrete ways to handle it.
Enter your peak-season order volume, packages per order and AOV. Adjust the carrier mix to your reality and the surcharge rates to your carrier's published peak schedule. You get the total surcharge bill, the per-order cost, what it is as a % of your AOV, and what shifting everything to your cheapest carrier would save.
Surcharges and discounts hit the same margin pool. Run the Sale Discount Planner alongside this so your Black Friday pricing survives both.
Carriers typically publish peak windows from late September through January. Check your carrier's current peak schedule — the defaults here reflect 2026–27 published rates and are editable.
If the hit is small (~1% of AOV), absorbing is simplest. Above ~3% of AOV, passing part of it through or shifting carriers beats silently eroding margin — but model the conversion impact first.
Yes — if you offer free shipping, the surcharge is pure margin loss. Raising the free-shipping threshold during peak is a common lever; model it against the discount planner.
Often partially: volume commitments, carrier-mix shifts and early negotiation (by October) earn waivers or discounts. The 'shift to cheapest carrier' row shows your maximum theoretical saving to negotiate against.
