Fixed vs. Earned Shipping Discounts: Understanding the Key Differences
Quick answer: A fixed discount is a set percentage off a shipping service that does not change during your contract. An earned discount is a volume-based discount that depends on how much you spend with the carrier, so it can rise or fall from week to week. Most contracts use both, and your real price depends on how they combine.
If you ship with UPS or FedEx on a negotiated contract, your carrier discounts almost always come in two forms: fixed discounts and earned discounts. On the contract they look similar. On your invoice they behave very differently.
One stays the same no matter how much you ship. The other moves up and down with your volume, sometimes without anyone on your team noticing.
This guide explains fixed vs earned discounts in plain terms, shows how they appear on an invoice, and covers what to check before you sign your next carrier agreement.
What are shipping discounts in a carrier contract?
Shipping discounts are negotiated reductions off a carrier’s published list rates. Without a contract, you pay the standard daily rates. With one, the carrier agrees to take a percentage off specific services, such as Ground, 2-Day Air, or Next Day Air.
Parcel shipping discounts are often set by service, weight range, and zone. A contract might give one discount on 1 to 5 lb Ground packages and a smaller one on heavier packages. Most of these discounts fall into two groups: fixed and earned.
What is a fixed discount?
A fixed discount is a set percentage off a service that stays the same for the life of the contract, regardless of how much you ship.
For example, your contract might give you 20% off UPS Ground. Whether you ship 200 packages this week or 2,000, that 20% applies.
Fixed discounts are predictable. You can budget around them, and a slow month does not change them. Note that “fixed” means the discount does not move with volume. It does not mean it applies to every package. A fixed discount can still be limited to certain weights, zones or services.
What is an earned discount?
Earned discounts are one of the most common volume based discounts in carrier contracts. They depend on how much you spend with the carrier. The more you ship, the higher the discount tier you reach.
This is measured by carriers, typically using your average weekly shipping charges over a rolling 52-week period. Your average places you in a tier, and each tier carries an extra discount. The calculation is usually updated weekly, so your tier, and your price, can change during the contract.
Here is a simplified example of an earned discount table:
Tier | Average weekly spend | Earned discount on Ground |
1 | Under $5,000 | 0% |
2 | $5,000 to $9,999 | 8% |
3 | $10,000 to $19,999 | 12% |
4 | $20,000 and above | 16% |
Illustrative figures only. Real tier thresholds and percentages vary by contract.
Earned discounts reward growth. They also carry risk, because a drop in volume can quietly push you into a lower tier.
What is the difference between fixed vs earned discounts?
The main difference is stability. A fixed discount is locked in. An earned discount depends on your shipping volume and can change during the contract.
Fixed discounts | Earned discounts | |
What it is based on | The service, weight or zone | Your shipping spend with the carrier |
Can it change mid-contract? | No | Yes, as your spend changes |
Predictability | High | Depends on how steady your volume is |
Main benefit | Easy to budget | Rewards growth |
Main risk | Can be lower than what you could earn | Can drop if volume falls |
How do fixed and earned discounts work together on an invoice?
In most contracts, both discounts apply to the same shipment and are added together.
Say a Ground package has a list rate of $20.00. Your contract gives a 20% fixed discount, and you are in Tier 3 with a 12% earned discount. Your total discount is 32%, so you pay $13.60.
Now suppose your average weekly spend dips and you fall into Tier 2. Your earned discount drops to 8%, and your total falls to 28%. The same package now costs $14.40.
That is 80 cents more per package. If you ship 500 Ground packages a week, that adds up to $400 a week, or about $20,800 a year. Nothing on your shipping floor changed. Only the tier did.
Why can earned discounts drop when nothing seems to change?
Earned discounts follow your spend, not your effort. Here are a few common situations that can lower your tier:
Seasonal slowdowns pull down your rolling 52-week average.
Losing a large customer reduces weekly volume.
Moving volume to another carrier can drop your spend below a tier threshold with your main carrier.
Introductory periods ending. Many contracts place new shippers in an assumed tier for the first few weeks. Once that period ends, your actual volume sets the tier. If the forecast was optimistic, the discount falls.
Excluded services. Some services may not count toward the tier calculation, even though you ship them.
Because these changes happen gradually, many teams only notice them weeks later, when invoices start looking higher.
How do earned discounts affect manufacturers?
The same contract structure can play out very differently depending on how a business ships.
Manufacturers often send fewer, heavier, and bulkier packages. Spend can be uneven, rising around large orders or production runs and falling in between. A strong quarter can lift the rolling average, then a quiet stretch can pull it back down. Heavy and oversized parcels also attract dimensional weight charges and large package surcharges, which raise the total bill even when the earned discount looks healthy.
Knowing which pattern fits your business helps you decide how much of your contract should rely on volume.

Which is better: fixed or earned discounts?
Neither is better on its own. The right mix depends on how steady your shipping volume is.
Steady or growing volume: Earned discounts can work in your favor, because you are likely to stay in or climb into higher tiers.
Seasonal or unpredictable volume: A larger share of fixed discounts protects you from tier drops in slow periods.
Most shippers: A balance of both, with the fixed portion covering your core services.
The better question is not which discount looks bigger on paper. It is which discount you will actually receive, week after week, based on how you really ship.
How do you know which discount you are actually receiving?
The discount on your contract and the discount on your invoice are often not the same. To see the real number, look at your effective discount: the actual percentage you paid below list rates.
Pull your invoice data for at least the last few months.
Compare the charged rate to the list rate for each shipment.
Calculate the effective discount by service, weight and zone.
Track your earned discount tier week by week.
Check whether minimum charges are overriding your discounts.
That last step matters more than most teams expect. Carriers often set a minimum net charge per package. On light, short-distance packages, the minimum can kick in and cancel much of your discount. A contract that says 40% off may deliver far less on those shipments.
How often should you review your shipping discounts?
A regular review keeps small changes from turning into high costs.
Monthly: Compare your effective discount with your contracted discount by service.
Quarterly: Look at your earned discount tier over time and note any weeks you slipped.
Three to six months before renewal: Pull a full year of shipment data so you can test new terms properly.
Reviews do not need to be complicated. The goal is to catch changes early, while you still have time to adjust packaging, service choices or carrier conversations.
What should you check before signing or renewing a carrier contract?
Carrier contracts are usually renegotiated only every few years, so it pays to test the terms against real data first.
Model the earned tiers against your actual history. Use a full 52 weeks, including slow months.
Ask where you will land after the introductory period. Know the tier your real volume supports.
Check the split. How much of the headline discount is fixed, and how much depends on volume?
Review minimum charges. See how they affect your lightest and shortest shipments.
Confirm which services count toward your tier.
Look beyond base rates. Accessorials, surcharges and dimensional weight rules can outweigh a small difference in discount percentages.

FAQs
Q: Are volume based discounts the same as earned discounts?
A: Mostly, yes. An earned discount is the most common type of volume based discount in UPS and FedEx contracts. The discount you get depends on how much you spend with the carrier over time, and it changes as your spend moves between tiers.
Q: Can you negotiate earned discount tiers?
A: Yes. The tier thresholds, the discount at each tier, which services count toward your spend, and the length of any introductory period can all be discussed during negotiation. If your volume is uneven, push for lower thresholds or a larger fixed portion.
Q: What happens to my earned discount if my shipping volume drops?
A: Your rolling average falls, and once it drops below a tier threshold, you move to a lower tier. The smaller discount then applies to the shipments that follow. Because the average covers 52 weeks, the change is gradual and easy to miss on a single invoice.
Q: Do shipping discounts apply to surcharges and accessorial fees?
A: Usually not automatically. Fixed and earned discounts generally apply to the base transportation charge. Accessorials such as residential delivery, address corrections or additional handling are only discounted if your contract says so. Fuel surcharges are typically calculated as a percentage on top.
Q: What is an effective discount rate?
A: Your effective discount rate is the actual percentage you paid below the carrier’s list rates once every charge on the invoice is counted. It is often lower than the discount in your contract because of minimum charges, surcharges and changes in your earned tier.
Q: Does a bigger discount always mean lower shipping costs?
A: No. A contract with a higher headline discount can still cost more if it has higher minimum charges, stricter dimensional weight rules or fewer discounts on accessorials. The total cost per package is a better measure than the discount percentage alone.
Q: Can small businesses get carrier discounts?
A: Yes. Many small and mid-sized shippers have negotiated carrier discounts, although the tiers and percentages are usually smaller than those offered to high-volume shippers. Knowing your shipping profile in detail helps you ask for terms that fit how you actually ship.
