Fixed vs Floating Pay: Why I Always Go Max Floating
When you sign or renew an ISPA (Independent Service Provider Agreement), one of the numbers you negotiate is the split between fixed pay and floating pay — the predictable weekly base versus the part that moves with volume, fuel, and weekly conditions. Contracts typically land somewhere between 40/60 and 25/75 fixed-to-variable. Most operators treat that split as a footnote. I treat it as one of the most consequential terms in the whole agreement.
If you’re not yet clear on what those two buckets are or where they appear on your weekly statement, start with how to read your settlement statement — this piece picks up where that one leaves off and makes the case for one side of the split.
This is one operator’s strongly held preference, not financial advice. Your market, your cost structure, and your risk tolerance are yours to weigh with your own advisors.
The case for max floating
I always negotiate for the highest variable share I can get. FedEx Ground volume is tied to e-commerce, and e-commerce has grown every single year for more than a decade. When volume goes up, costs go up with it — drivers, fuel, trucks, wear. If your settlement is mostly fixed pay, you’re absorbing all that cost growth while your top line stays flat. That’s brutal.
Here’s the long view on U.S. e-commerce growth, year over year:
| Year | YoY Growth in U.S. E-Commerce | E-Commerce % of Total U.S. Retail |
|---|---|---|
| 2016 | (base year) | 7.9% |
| 2017 | 15.5% | 8.8% |
| 2018 | 14.4% | 9.7% |
| 2019 | 12.7% | 10.6% |
| 2020 | 42.2% (COVID surge) | 14.6% |
| 2021 | 17.3% | 14.6% |
| 2022 | 6.5% | 14.4% |
| 2023 | 9.0% | 15.4% |
| 2024 | 7.6% | 16.1% |
| 2025 | 5.4% | 16.4% |
| 2026 (Q1) | 9.7% (vs Q1 2025) | 16.8% |

E-commerce was 7.9% of total U.S. retail in 2016. By Q1 2026, it had grown to 16.8% — more than doubling in a decade. Even at the post-2022 normalized rate, e-commerce is still growing in the mid-to-high single digits every year, and FedEx Ground volume tracks it closely.
Now consider how much room there still is to grow. E-commerce at 16.8% of retail means 83% of consumer spending still happens offline today. Every point of share that migrates online is a tailwind for the parcel network. And within that network, FedEx handles roughly 17% of U.S. parcel volume (per the 2024 Pitney Bowes Parcel Shipping Index) — meaningful, but a fraction of the overall pie alongside USPS, Amazon Logistics, and UPS. A FedEx Ground contractor isn’t running a mature, capped operation. They’re running a small slice of a rapidly growing slice of total consumer spending.
Why fixed-heavy contracts squeeze you
The implication is straightforward. In a floating-heavy contract, you participate in that growth automatically — when volume climbs, your revenue climbs with the cost. In a fixed-heavy contract, by the end of a two-year term you can be running more trucks and absorbing more cost while still earning the number you locked in at signing. That’s not stability — that’s getting squeezed.
The argument for fixed pay is “more dependable.” That’s true in a stable market — but in the growing market FedEx contractors have always operated in, “dependable” often means dependably falling behind.
There’s a floor to the risk, too. A higher floating share does mean more downside in a genuinely slow week. But the daily stop threshold set in your ISPA, the peak supplemental, and the fixed service charge you still keep all put a base under you. You’re not betting the business on volume — you’re choosing to participate in a trend that has run in one direction for over a decade, instead of opting out of it.
What this means at the negotiating table
When the ISPA is on the table, the fixed/floating split is a real lever, not a take-it-or-leave-it line. Push for the highest variable share the agreement will bear, understand the daily stop threshold the contract is structured around, and know that a higher floating share is a bet on the same e-commerce trend that brought you into this business in the first place.
Run the specific numbers for your station and your cost structure past someone who knows this business before you sign. The direction of the argument, though, has been consistent for a decade: the volume keeps growing, and you want your contract pointed into that growth, not away from it.
The single sentence to take with you
If you remember one sentence from this article, make it this one:
FedEx Ground volume rides a decade-plus e-commerce trend, so a fixed-heavy ISPA leaves you running more trucks and absorbing more cost for the same flat number — negotiate for the highest floating share you can get and participate in the growth instead of opting out of it.
Read your settlement, know your split, and aim your next contract into the trend.
