Binding Not-to-Exceed Estimates: The Best Moving Contract You Can Get
Binding not-to-exceed estimates cap your moving cost at the quoted price but allow discounts if actual weight is lower. Here's why this rare contract type protects you most.
What a Binding Not-to-Exceed Estimate Actually Means
A binding not-to-exceed estimate is the gold standard of moving contracts, but fewer than 15% of interstate movers offer it. Here's the deal: the mover quotes you a maximum price based on the estimated weight of your shipment. If your actual weight comes in lower, you pay the lower amount. If it comes in higher, you still pay only the original estimate.
You win either way. It's a price ceiling with a trapdoor.
The Federal Motor Carrier Safety Administration (FMCSA) defines this estimate type in 49 CFR §375.401(b)(3). The regulation requires the mover to honor the quoted maximum—no exceptions—while passing savings to you if the actual transportation charges are less.
Example: Your mover quotes $4,800 for an estimated 6,000 pounds from California to Texas. At delivery, the certified weight ticket shows 5,200 pounds. Your final bill drops to $4,160 (assuming $0.80/pound). But if the weight had been 6,800 pounds, you'd still pay only $4,800.
How This Differs from Regular Binding Estimates
Most movers who offer binding estimates stop at the simpler version: you pay the quoted price, period. If the actual weight is less, you don't get a refund. If it's more, you don't pay extra. It's a flat contract.
A binding not-to-exceed estimate adds consumer protection on the downside. You're never locked into paying for phantom weight.
The distinction matters on long-haul moves where estimates can miss by 1,000+ pounds. A family moving from New York to Florida might receive a binding estimate of $6,200 for 7,000 pounds. If they pare down and ship only 6,000 pounds, a standard binding estimate still charges $6,200. A binding not-to-exceed estimate refunds roughly $885.
Why So Few Movers Offer This Contract Type
Binding not-to-exceed estimates shift risk entirely to the carrier. If the mover underestimates your shipment weight, they absorb the loss. If they overestimate, they refund the difference. There's no margin for error and no upside for the company.
As a result, movers who offer this contract type tend to be exceptionally cautious during the pre-move survey. They'll measure furniture, count boxes, and ask detailed questions about what you're leaving behind. Some will add a 10–15% buffer to the weight estimate to protect themselves, which can make the initial quote look higher than a competitor's non-binding estimate.
But that higher quote is honest. A non-binding estimate from a less scrupulous mover might lowball you at $3,800, then hit you with a $5,400 bill at delivery when the "actual" weight (often inflated) comes in higher. You can read more about this tactic in our guide on how to avoid hostage loads.
The Weight Ticket Is Your Proof
Under 49 CFR §375.509, your mover must weigh the truck before loading your shipment and again after loading. The difference is your shipment weight. You have the right to observe both weighings or to request copies of the certified weight tickets.
With a binding not-to-exceed estimate, those tickets determine your final bill. If the mover quotes you $5,000 for 5,500 pounds and the tickets show 4,800 pounds, you pay for 4,800 pounds. If the tickets show 6,200 pounds, you pay $5,000.
Always demand a weight ticket before you pay. Movers who refuse to provide one are violating federal law. On an interstate move, the FMCSA requires the weight ticket to come from a certified scale, and the mover must give you a copy within a reasonable time after delivery.
How to Find Movers Who Offer Binding Not-to-Exceed Estimates
Start by asking directly. When you request quotes, specify that you want a binding not-to-exceed estimate in writing. If the sales rep hesitates or tries to steer you toward a non-binding estimate, that's a red flag.
Reputable carriers will put the estimate type in bold at the top of the contract. Look for language like "This is a binding not-to-exceed estimate as defined in 49 CFR §375.401(b)(3)." If the paperwork says "binding estimate" without the "not-to-exceed" clause, clarify before you sign.

What to Watch for in the Fine Print
Even a binding not-to-exceed estimate has limits. The price cap applies only to the services listed in the estimate. If you add stops, request additional packing, or ask the crew to disassemble furniture not mentioned in the original survey, the mover can charge extra.
Read the "Additional Services" section carefully. Some contracts include language like "Customer agrees that any services not listed above will be billed at the carrier's standard hourly rate." That's fine—it's fair—but know what's covered and what's not before the truck arrives.
Also confirm the delivery window. A binding not-to-exceed estimate locks in the price, but it doesn't guarantee a delivery date unless the contract explicitly says so. If you need your belongings by a specific day, get that in writing as a "guaranteed delivery" and understand that it may cost 20–30% more.
When a Binding Not-to-Exceed Estimate Isn't Worth It
If you're moving a small apartment (under 2,000 pounds) or a single room, the administrative overhead of a binding not-to-exceed estimate may not make sense. Many movers set minimum weights—often 1,000 or 1,500 pounds—for this contract type. Below that threshold, you're better off with an hourly rate or a flat-fee quote.
For local moves (under 50 miles), hourly billing is standard. Binding not-to-exceed estimates apply almost exclusively to interstate moves where weight and distance determine the cost. If you're moving within Chicago or across town in Los Angeles, ask about hourly rates with a not-to-exceed cap instead. Some movers will quote you 6 hours at $140/hour with a $900 ceiling—a similar concept, different structure.
The Math: Why This Estimate Type Saves You Money
Let's compare three estimate types on a 1,200-mile move from Florida to Georgia:
| Estimate Type | Quoted Weight | Actual Weight | Quoted Price | Final Bill |
|---|---|---|---|---|
| Non-binding | 5,000 lbs | 6,000 lbs | $3,800 | $4,560 |
| Binding | 5,000 lbs | 6,000 lbs | $4,200 | $4,200 |
| Binding not-to-exceed | 5,000 lbs | 4,200 lbs | $4,200 | $3,528 |
The non-binding estimate looks cheapest up front but exposes you to a 20% overage. The binding estimate protects you from overages but doesn't reward you for shipping less. The binding not-to-exceed estimate caps your risk and passes savings through when you come in under weight.
On a $4,000 move, the difference between a binding and a binding not-to-exceed estimate can be $400–$600 if your actual weight is 10–15% lower than estimated. That's real money.
How to Negotiate This Contract Type
If a mover offers only binding or non-binding estimates, ask if they'll convert to binding not-to-exceed for a small fee. Some carriers will agree to a $100–$150 surcharge in exchange for the added consumer protection. It's worth it.
Alternatively, if the mover's standard binding estimate is $4,800 and you're confident your shipment will weigh less than estimated, propose a binding not-to-exceed contract at $5,000. You're giving the mover a 4% buffer in exchange for downside protection. Many will accept that trade.
Get everything in writing. Email confirmations and phone promises don't count. The estimate document you sign before the move is the only thing that matters if a dispute arises.
What Happens If the Mover Violates the Contract
If your mover tries to charge you more than the binding not-to-exceed estimate—or refuses to refund the difference when your actual weight is lower—you have recourse under 49 CFR §375.401(b)(3). File a complaint with the FMCSA at https://nccdb.fmcsa.dot.gov and document everything: the signed estimate, the weight tickets, and any communication with the mover.
You can also withhold payment above the contracted maximum. If the mover quoted $5,000 and demands $5,800 at delivery, pay the $5,000 and refuse the rest. The mover cannot legally hold your belongings hostage for charges that exceed a binding not-to-exceed estimate. (This is different from a non-binding estimate, where the mover can demand up to 110% of the estimate before unloading.)
If the mover retaliates by refusing to unload, call the FMCSA hotline immediately: 1-888-DOT-SAFT (1-888-368-7238). You may also have grounds for a lawsuit in small claims court, especially if the mover's behavior meets the definition of a hostage load under federal law.
Why This Matters More on High-Value Moves
The bigger your shipment, the more a binding not-to-exceed estimate protects you. On a 12,000-pound move from California to Florida, a 10% weight variance equals $800–$1,200. On a 3,000-pound move from Texas to Colorado, it's $200–$300.
If you're also purchasing full-value protection (which you should), the cost of that coverage is often calculated as a percentage of the total transportation charges. A binding not-to-exceed estimate that reduces your final bill by $600 will also reduce your valuation premium by $30–$60.
Every dollar you save on the base move is a dollar you can put toward better insurance, temporary housing, or simply keeping in your pocket.
FAQs
What's the difference between a binding estimate and a binding not-to-exceed estimate?
A binding estimate locks in the price regardless of actual weight. A binding not-to-exceed estimate sets a maximum price but refunds you if the actual weight is lower. You pay the quoted amount or less—never more. It's defined in 49 CFR §375.401(b)(3).
Why don't more movers offer binding not-to-exceed estimates?
This contract type shifts all risk to the mover. If they underestimate your weight, they lose money. If they overestimate, they refund the difference. Most carriers prefer binding or non-binding estimates because those structures protect their margins.
Can a mover charge me more than the binding not-to-exceed estimate?
No. The estimate is a legal cap. If your mover tries to charge more at delivery, you can refuse to pay the excess and file a complaint with the FMCSA. The only exception is if you add services not listed in the original estimate, like extra stops or packing.
How do I know if my actual weight is accurate?
Demand certified weight tickets from before and after loading. Federal law (49 CFR §375.509) requires movers to weigh the truck at a certified scale and give you copies. You have the right to observe both weighings. Never accept a bill without seeing the tickets.
Is a binding not-to-exceed estimate worth it for a small move?
Usually not. Most movers set minimum weights (1,000–1,500 pounds) for this contract type. If you're moving a studio apartment or a few rooms, an hourly rate or flat-fee quote is simpler and often cheaper. Binding not-to-exceed estimates make the most sense on shipments over 3,000 pounds.
What if my mover only offers non-binding estimates?
Ask if they'll convert to binding not-to-exceed for a small fee, or find a different mover. Non-binding estimates expose you to unlimited cost overruns at delivery. A mover who refuses to offer binding contracts is a red flag—they may be planning to lowball the estimate and inflate the final bill.
Can I negotiate a binding not-to-exceed estimate if the mover doesn't advertise it?
Yes. Offer to accept a slightly higher maximum price in exchange for downside protection. For example, if the mover quotes $4,500 binding, propose $4,700 binding not-to-exceed. You're giving them a buffer, and they're giving you a refund if actual weight is lower. Get it in writing before you sign.
