UPS and FedEx minimum net charges: why a bigger discount may not save money
The short version
- The minimum net charge is a floor under the transportation charge only. Fuel, residential, delivery area and other surcharges are added on top of whichever amount is billed.
- Both carriers bill the greater of the discounted rate and the minimum. Below the crossover point, a deeper discount does not reduce the transportation charge.
- Minimums are usually set as an adjustment off the published rate for the lightest package, so they rise with every general rate increase unless the agreement fixes them.
- A larger discount pushes the crossover to heavier packages, so the floor governs more of your volume, not less.
- The minimum is negotiable on its own. On a light package mix, a lower minimum is often worth more than a higher discount.
A UPS or FedEx minimum net charge is the lowest transportation charge the carrier will bill for a package, whatever your discount says. Both carriers' agreements bill the greater of two numbers: the published rate less your discount, or the minimum. Take a package that lists at $20 under an agreement with a 65% discount and an $11 minimum. The discount produces $7, but $7 is below the floor, so the billed transportation charge is $11, before fuel and surcharges are added. Raise the discount to 70% and the calculation produces $6, and the bill is still $11. On that package, the extra five points of discount save nothing.
That is why a bigger discount may not lower your costs. For light packages and short distances, the ones most ecommerce and B2B shippers send most often, the minimum, not the discount, often sets the price. What decides your cost is how many of your packages sit under the floor and how the floor itself is defined in your agreement.
The transportation-charge floor, before any discount
Every UPS and FedEx agreement starts from the published list rate for the service, weight and zone. The discount is applied to that rate, and the result is the net transportation charge. The minimum net charge is a separate term that says the net transportation charge cannot fall below a stated amount.
Billed transportation charge = the greater of (list rate × (1 − discount)) and the minimum net charge.
The carriers' own agreements say it the same way. A UPS Carrier Agreement in the public record reads: "For each shipment, Customer agrees to pay the greater of the (a) net shipment charge based on the above incentives or (b) the minimum net shipment charge." A FedEx Transportation Services Agreement filed with the SEC reads: "Customer agrees to pay the greater of the net charge based on Customer's discounts, if any, for a given Service or the minimum net charge as defined in the FedEx Service Guide or on fedex.com."
The floor applies to the transportation charge alone. Fuel is then calculated on the billed amount, and residential, delivery area and other surcharges are added as usual, so a package billed at the minimum still carries every other charge on the invoice.
The example: 65% and 70% against an $11 minimum
A package that lists at $20, under an agreement with an $11 minimum:
| Discount | List less discount | Minimum | Billed transportation charge | Discount actually earned |
|---|---|---|---|---|
| 65% | $7.00 | $11.00 | $11.00 | 45% |
| 70% | $6.00 | $11.00 | $11.00 | 45% |
Illustrative figures. Fuel and surcharges are added after the minimum.
Both agreements bill exactly the same amount. The 65% agreement earns 45% against list on this package, and so does the 70% one. The five-point improvement only starts to count on packages heavy or distant enough that 70% off still lands above $11, which takes a list rate above $36.67.
Where the floor governs, on real list rates
The same $11 minimum against the FedEx Ground and Home Delivery list rates effective January 5, 2026. The crossover is the lightest billable weight in each zone at which the discounted rate first exceeds the floor. Below it, every package is billed $11.
| Zone | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
|---|---|---|---|---|---|---|---|
| Crossover at 65% | 62 lb | 39 lb | 33 lb | 26 lb | 20 lb | 15 lb | 14 lb |
| Crossover at 70% | 74 lb | 51 lb | 39 lb | 33 lb | 24 lb | 19 lb | 16 lb |
Calculated by ebb Logistics from the FedEx Standard List Rates, effective January 5, 2026. The $11 minimum and both discounts are illustrative.
At 65%, every zone 5 package up to 25 lb is billed $11. A 10 lb zone 5 package lists at $20.46, close to the example above, and is billed $11 under both agreements. Raising the discount to 70% moves the zone 5 crossover from 26 lb to 33 lb, so more of your packages land on the floor, not fewer. You can open this example in the minimum charge calculator and change either term.
How UPS and FedEx set the minimum
Agreements rarely state the minimum as a single fixed number. More often it is an adjustment off a published rate, which is why the minimum changes when list rates do.
- UPS. The UPS agreement above states that the "Minimum net shipment charge is calculated by deducting the applicable percent off or amount off (by zone) in the table(s) below from the published list rate for the respective service", with a separate adjustment for each service. It also says the minimum rates are "derived from the most recently published Daily Rates" and "subject to change based on changes to such list rates".
- FedEx. The FedEx agreement provides that, where reductions apply, "the minimum net charge for each Service will be revised as the applicable base rate for the zone(s) and weight(s) combination(s) less any reduction amount", and that "minimum charges are subject to change with any increase in applicable base rate during the time period of the Agreement".
In practice the base for a ground minimum is usually the published rate for the lightest package in the nearest zone, the 1 lb zone 2 rate, which is $11.99 on FedEx Ground in 2026. An agreement that sets the minimum as that rate less a percentage or a dollar amount is a minimum that rises with every general rate increase, without anyone renegotiating it. Minimums are also set per service, so ground, home delivery, Ground Saver or Ground Economy, and each air service can each have their own.
Why a bigger discount can make the floor matter more
A deeper discount pulls the discounted rate down, so it takes a heavier or more distant package for the discounted rate to climb back above the same floor. Every crossover moves up. A proposal that leads with a higher discount percentage needs to be read alongside its minimum: if the minimum did not move, a larger share of your packages will be billed at it, and the improvement you were sold applies to fewer of them.
The reverse holds too. Lowering the minimum while leaving the discount alone reduces the price of every package below the crossover, which on a light package mix can be most of the file. That is why two agreements have to be compared on your own shipments: the one with the bigger discount is not reliably the cheaper one.
What to negotiate instead
Ask for the minimum directly. A minimum adjustment, expressed as a larger percentage or dollar reduction off the base rate, by service and zone where your volume concentrates, reaches exactly the packages a bigger discount cannot. In one engagement, a distributor with a 65% UPS Ground discount had more than half of its Ground packages billed at the minimum; renegotiating the minimum, fuel and several accessorials cut projected annual parcel spend by $318,000 without changing carrier or shipping practices.
Before you ask, measure three things: the share of your packages billed at the minimum, by service and zone; how your agreement defines the minimum and whether it is tied to the published rate; and what each point of minimum adjustment would be worth on your own volume. Then check invoices against the agreement, because a minimum billed above the agreed amount is a billing error and can be claimed back, while a correctly billed minimum is a negotiation item.

Frequently asked questions
What is a UPS minimum charge?
It is the lowest net transportation charge UPS will bill for a package or shipment under your agreement. UPS bills the greater of the charge produced by your incentives and the minimum net charge, and agreements commonly calculate the minimum by deducting a percentage or dollar amount from the published list rate for each service. It applies before fuel and surcharges, which are added on top.
What is a FedEx minimum net charge?
It is the floor on the net transportation charge for a FedEx package. FedEx agreements bill the greater of the net charge after your discounts or the minimum net charge for that service, as defined in the FedEx Service Guide or reduced by your agreement. Reductions are typically expressed against the applicable base rate, and the minimum rises when base rates rise.
Why didn't a bigger discount lower our shipping costs?
Because many of your packages are probably billed at the minimum. When the discounted rate falls below the floor, the floor is billed, and a deeper discount only pushes the discounted rate further below it. On a $20 list package with an $11 minimum, 65% and 70% discounts both bill $11.
Can the minimum net charge be negotiated?
Yes. It is a contract term like the discount, set by service and often by zone, and carriers will negotiate it separately. For a shipper with light, short-distance packages, a lower minimum is often worth more than a higher discount, because the discount only matters above the crossover.
Does the minimum charge include fuel and surcharges?
No. The minimum is a floor on the transportation charge. Fuel is calculated on the billed transportation charge, whether that is the discounted rate or the minimum, and residential, delivery area and other surcharges are added on top.
Does the minimum net charge change every year?
Usually, yes. When the minimum is defined as an adjustment off a published rate, it rises with the general rate increase each January. A minimum stated as a fixed dollar amount stays where it is until renegotiated. Your agreement says which kind you have.
