Most shippers negotiate once, sign the agreement, and assume the percentages are locked in. They are not. A large slice of what you pay per label is governed by earned discounts — incentives that move up or down on their own as your spend with the carrier changes, without anyone renegotiating anything.
FedEx calls them Earned Discounts. UPS calls them Portfolio Tier Incentives. The mechanics differ in the details, but the principle is the same: the carrier measures what you spend over a rolling window, drops you into a tier, and applies that tier’s percentage on top of your base incentives. Ship more, the percentage climbs. Ship less for a few months, it quietly falls.
That makes earned discounts the one line in your pricing you can move without a single conversation with your rep — and the one that erodes fastest when volume dips. Here is how the machinery actually works, and where the money is.
What an earned discount actually is
Your carrier agreement typically stacks three kinds of reduction:
- Guaranteed (base) discounts. Fixed percentages applied to every shipment that matches a service, weight band and zone. These do not move.
- Earned or tier incentives. An additional percentage that depends on how much you spent recently. These move every measurement period.
- Accessorial concessions. Waivers or reductions on residential, delivery area, additional handling and similar charges.
Carriers introduced tier incentives to close a gap in the older zone-and-weight model, which let a shipper win deep discounts while awarding the carrier only a thin slice of its total parcel volume. Tier incentives reward the whole portfolio, not one clever lane.
The number that decides your tier
Almost every tier table is built on gross transportation charges — the published base rate for the movement, before fuel surcharge, before accessorials, before duties and taxes, and before your own discounts are applied. This matters more than it sounds. A shipper looking at a $90,000 monthly invoice may only be presenting $55,000–$65,000 of qualifying transportation charges, because fuel and accessorials are stripped out first.
The measurement window is usually a rolling 52-week average, annualized. Some UPS agreements use a rolling 13-week window instead, which reacts far faster — in both directions. A strong Q4 can lift a 13-week tier by February and give it all back by May.
What counts toward the tier, by carrier
The two carriers do not measure the same thing, and the difference changes which shipments are worth consolidating onto one account.
| Element | FedEx Earned Discounts | UPS Portfolio Tier Incentives |
|---|---|---|
| Base of calculation | Annualized gross transportation charges | Gross transportation charges |
| Typical measurement window | Rolling 52 weeks | Rolling 52 weeks; 13 weeks in some agreements |
| Fuel surcharge included? | Generally no | Generally no |
| Residential surcharge counted? | Generally excluded | Commonly included |
| Delivery area / extended area surcharge counted? | Generally excluded | Commonly included |
| Services aggregated | Usually Ground and Express | Portfolio across Ground, Air and International; sometimes other modes |
| Effect of a volume drop | Tier falls at the next measurement | Tier falls at the next measurement |
Tier structures, thresholds and percentages are negotiated per account and are not published. Treat everything above as the shape of the mechanism, not as a quote — your own agreement and your rep are the only authority on your numbers.
The residential and delivery-area line is the one worth re-reading. If your mix is heavily e-commerce and residential, a UPS portfolio base can look materially larger than the equivalent FedEx base on the same shipments — which is exactly why the two carriers’ tier tables are not comparable side by side.
The tier trap: volume that buys you nothing
Two positions on a tier table cost shippers real money, and both are easy to sit in for a year without noticing.
Just under a threshold. If the next tier starts at a spend level you are missing by a few percent, every package you ship is earning the lower percentage. Closing that gap is usually cheaper than it looks: moving one recurring freight lane, a returns program, or a second business unit onto the same account can be enough.
At the top of the table. Once you are in the highest tier, additional volume adds nothing to that line. Growth past that point should be converted into something else — deeper base discounts, accessorial waivers, a better minimum charge — rather than left on the table.
Five moves that pull you into the next tier
- Consolidate accounts. Separate account numbers across divisions, brands or warehouses split one qualifying spend into several small ones. Consolidating is often the single largest tier move available.
- Pull third-party and collect volume onto your account. Shipments billed to someone else generally do not build your base, and third-party billing adds a percentage surcharge of its own.
- Check which modes are aggregated. If your agreement counts freight or international alongside small parcel, volume you already ship may qualify and simply is not being credited.
- Know your window before you cut volume. On a 13-week measurement, a deliberate January slowdown can cost you a tier by spring. On a 52-week average, the same dip barely registers.
- Audit the base, not the invoice. Ask your rep in writing what your current qualifying spend is, what the next threshold is, and which charges are excluded. The gap is frequently small and nobody volunteers it.
What to track every month
Three figures are enough to stay in control: your qualifying transportation charges for the current window, the threshold for the next tier, and the percentage that threshold would add. Put them on one line of a monthly report. A shipper who watches those three numbers catches a slipping tier a quarter before it shows up as a higher cost per label — and spots the months when a small shift in volume pays for itself several times over.
Earned discounts are not a reward the carrier hands out. They are a formula, and formulas can be worked.
If you would rather not run that formula yourself, ShipPayLess gives everyday shippers access to pre-negotiated commercial rates, so you are not starting from retail pricing or waiting on a tier to improve. Compare what you are paying today and see where the gap is.
