Most shippers negotiate once, sign the agreement, and assume the percentages are set in stone. They are not. A large portion of what you pay per label is determined by earned discounts — incentives that adjust automatically as your spending with the carrier changes, without anyone having to renegotiate 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 tracks your spending over a rolling period, assigns you to a tier, and applies that tier’s percentage on top of your base incentives. Ship more, and the percentage goes up. Ship less for a few months, and it quietly goes down.
That makes earned discounts the one item in your pricing that you can adjust without even speaking to your sales rep—and the one that erodes the fastest when sales volume drops. Here’s how the system actually works, and where the money is.
What an earned discount actually is
Your carrier agreement typically combines three types of discounts:
- Guaranteed (base) discounts. Fixed percentages applied to every shipment that meets the criteria for a specific service, weight band, and zone. These percentages do not change.
- Earned or tier-based incentives. An additional percentage that depends on how much you've spent recently. These percentages change with each measurement period.
- Ancillary concessions. Waivers or reductions on residential, delivery area, additional handling, and similar charges.
Carriers introduced tiered incentives to address a shortcoming in the older zone-and-weight model, which allowed a shipper to secure deep discounts while giving the carrier only a small portion of its total parcel volume. Tiered incentives reward the entire portfolio, not just one strategic route.
The number that determines your tier
Almost every tier table is based on high transportation costs — the published base rate for the shipment, before fuel surcharges, before ancillary charges, before duties and taxes, and before your own discounts are applied. This is more important than it sounds. A shipper reviewing a monthly invoice for $90,000 may only be reporting $55,000–$65,000 in qualifying transportation charges, because fuel and accessorials are deducted first.
The measurement window is usually a rolling 52-week average, on an annualized basis. Some UPS agreements use a rolling 13-week window instead, which reacts much more quickly—in both directions. A strong fourth quarter can push a 13-week tier up by February and wipe out all the gains by May.
What counts toward the tier, by carrier
The two carriers do not measure the same thing, and this difference determines which shipments are worth consolidating into a single account.
| Element | FedEx Earned Discounts | UPS Portfolio Tier Incentives |
|---|---|---|
| Basis for Calculation | Annualized gross transportation charges | High transportation costs |
| Typical measurement window | Rolling 52 Weeks | Rolling 52 weeks; 13 weeks in some agreements |
| Is the fuel surcharge included? | Generally no | Generally no |
| Is the residential surcharge included? | Generally excluded | Commonly included |
| Is the delivery area/extended area surcharge included? | Generally excluded | Commonly included |
| Aggregated Services | Usually Standard and Express | Portfolio spanning ground, air, and international transportation; occasionally other modes |
| Effect of a decrease in volume | Tier drops to the next measurement | Tier drops to the next measurement |
Tier structures, thresholds, and percentages are negotiated on a per-account basis and are not disclosed. Consider everything above as a general outline of how the mechanism works, not as a quote—your own agreement and your account representative are the only authoritative sources for your specific figures.
The residential and delivery-area line is the one worth reviewing. If your mix consists largely of e-commerce and residential shipments, a UPS portfolio can appear significantly larger than the equivalent FedEx portfolio for the same volume of shipments—which is exactly why the two carriers’ tier tables cannot be compared side by side.
The Tier Trap: Volume That Gets You Nowhere
Two positions on a tiered pricing table cost shippers real money, and it's easy to stay in either one for a year without even realizing it.
Just below a threshold. If the next tier begins at a spending level that you fall short of by a few percent, every package you ship will earn the lower percentage. Closing that gap is usually less expensive than it seems: simply moving a single recurring shipping route, a returns program, or a second business unit to the same account can be enough.
At the top of the standings. Once you reach the highest tier, additional volume does not increase that line item. Growth beyond that point should be converted into something else—deeper base discounts, waivers of ancillary fees, or a better minimum charge—rather than left on the table.
Five Steps to Take You to the Next Level
- Consolidate accounts. Separate account numbers across divisions, brands, or warehouses split a single qualifying transaction into several smaller ones. Consolidation is often the single largest tier advancement available.
- Import third-party data and aggregate the volume into your account. Shipments billed to someone else generally do not count toward your base, and third-party billing adds its own percentage-based surcharge.
- Check which modes are aggregated. If your agreement includes freight or international shipping in addition to small parcels, the volume you already ship may qualify but is simply not being credited.
- Know your window before you cut the volume. Based on a 13-week measurement, a deliberate slowdown in January could cause you to drop a tier by spring. Based on a 52-week average, the same dip is barely noticeable.
- Audit the base amount, not the invoice. Ask your representative in writing what your current qualifying spend is, what the next threshold is, and which charges are excluded. The difference is often small, and no one will tell you this on their own.
What to Track Every Month
Three figures are all you need to stay in control: your qualifying transportation charges for the current window, the threshold for the next tier, and the percentage increase that threshold would represent. Include them on a single line of a monthly report. A shipper who keeps an eye on those three numbers can spot a slipping tier a quarter before it results in a higher cost per label—and identify the months when a small shift in volume pays for itself several times over.
Earned discounts are not a reward that the carrier simply hands out. They are based on a formula, and formulas can be worked out.
If you'd rather not run that formula yourself, ShipPayLess gives everyday shippers access to pre-negotiated commercial rates, so you don't have to start at retail prices or wait for a tier to improve. Compare what you're paying today and see where the gap is.
