Most moving-day disputes do not start on moving day. They start weeks earlier, in a paragraph of the estimate that nobody read closely. Two quotes can arrive in your inbox looking almost identical — same company logo, same list of services, same dollar figure at the bottom — and mean completely different things. One is a contract for a price. The other is an educated prediction that the mover is allowed to revise once your belongings are on a scale.
That single distinction, binding versus non-binding, is the most consequential line on the page. It determines whether the number you budgeted for is the number you pay, how much leverage you have when the driver hands you a bill, and what happens if the final tally lands well above the estimate. It also happens to be the thing hidden-fee complaints almost always trace back to. This guide explains the three estimate types you will encounter, the federal rule that governs what a mover can collect at your door, and how to make sure the price you were quoted is the price that holds.
The Three Estimate Types at a Glance
Interstate movers work with three recognized estimate formats. Every quote you receive for a long-distance move should clearly identify itself as one of them, in writing, on the estimate document itself.
| Estimate Type | What You Pay | Can the Price Go Up? | Can It Go Down? | Best For |
|---|---|---|---|---|
| Non-Binding | Actual weight × tariff rate, plus services | Yes — capped at 110% due at delivery | Yes | Light, well-purged shipments where you expect to ship less than surveyed |
| Binding | The quoted figure, full stop | No — unless the job itself changes | No | Settled inventories and anyone budgeting to a fixed number |
| Binding Not-to-Exceed | The lesser of actual charges or the estimate | No | Yes | Almost everyone — ask for it by name |
Applies to interstate household moves regulated by the FMCSA. Local and intrastate moves are governed by state rules and are usually priced hourly — see the section on local moves below.
Non-Binding Estimates: A Guess With Rules Around It
A non-binding estimate is the mover's projection of what your move will cost, based on a survey of your belongings and the published tariff rate for your route. It is explicitly not a promise. The real charges are calculated after the loaded truck is weighed, and you pay for the weight that actually crossed the scale.
This is not a scam, and non-binding estimates are entirely legal and common. The problem is that consumers routinely treat the number as a price, build a budget around it, and then discover on delivery day that the shipment came in 900 pounds heavier than surveyed. Underestimating is easy to do honestly: garages, attics, basements, closets, and the contents of a home office are chronically undercounted, and a surveyor working from a walkthrough is guessing at what is inside every box.
The 110% rule, explained properly
Federal regulations give you one important protection here. On an interstate move with a non-binding estimate, the mover cannot require you to pay more than 110 percent of the estimated charges before releasing your goods. Pay the estimate plus up to 10 percent, and the crew must unload.
What trips people up is the second half of the rule. That extra balance is not forgiven — it is deferred. The mover has 30 days from delivery to invoice you for the remainder, and you owe it. Here is how the arithmetic plays out on a $4,000 non-binding estimate:
| Scenario | Actual Charges | Due at Delivery | Billed Within 30 Days | Total You Pay |
|---|---|---|---|---|
| Shipment lighter than surveyed | $3,600 | $3,600 | — | $3,600 |
| Right on the estimate | $4,000 | $4,000 | — | $4,000 |
| Modestly over | $4,300 | $4,300 | — | $4,300 |
| Well over the estimate | $4,800 | $4,400 (the 110% ceiling) | $400 | $4,800 |
| Badly underestimated | $5,600 | $4,400 (the 110% ceiling) | $1,200 | $5,600 |
Illustrative figures on a $4,000 non-binding estimate. The 110% ceiling limits what must be paid on delivery day; it does not limit the total cost of the move.
Read that last row again, because it is the whole reason this article exists. The 110 percent rule is a cash-flow protection that stops a driver from holding your furniture on the sidewalk while you scramble for money. It is not a price cap. A non-binding estimate that was 40 percent low is still a bill for 40 percent more than you planned — it just arrives in two installments.
Binding Estimates: A Number You Can Budget Against
A binding estimate is a fixed-price agreement. The mover reviews your inventory and the services you have requested, names a figure, and that figure is what you pay on delivery day — whether the truck weighs in over or under. The scale becomes the mover's problem instead of yours.
The trade-off is that you give up the upside. If your shipment comes in 500 pounds lighter than surveyed because you sold the sectional and donated four boxes of books, you do not get a refund. You agreed to a price, and the price is the price. Movers also know they are absorbing the risk, so a binding number typically carries a modest cushion — it is common for a binding quote to start a little above a non-binding quote from the same carrier for the same job. You are paying for certainty, and for most households that is money well spent.
When a binding estimate can legitimately change
Binding does not mean unchangeable under all circumstances. It means the price is bound to a specific job. If the job changes, the price can change — but only through a defined process, and only before loading:
- You add items. Anything not on the signed inventory — a second dresser, the contents of a storage unit, the patio set you decided to keep — entitles the mover to revise the estimate.
- You add services. Requesting packing, crating for a mirror or television, or disassembly that was not quoted are new line items.
- Access conditions differ from what was quoted. A long carry from the truck to the door, extra flights of stairs, or a shuttle because a tractor-trailer cannot reach the street are all chargeable, and all are frequent sources of dispute.
- Storage enters the picture. Storage-in-transit is a separate service with separate charges, including handling in and out.
When any of these come up, the mover has two lawful options: reissue a revised binding estimate that you sign before loading begins, or decline the binding arrangement and convert the move to tariff-based charges. What a mover cannot do is quietly load your goods under the original binding estimate and then present a larger bill at delivery for the same inventory and the same services. If that happens, your signed estimate and bill of lading are the documentation that settles it.
Compare Estimates Side by Side
The fastest way to see whether a quote is fair — binding or not — is to put it next to others for the same inventory and the same route.

The third format, a binding not-to-exceed estimate — also marketed as a guaranteed price or guaranteed-not-to-exceed — is the most favorable structure available to a consumer, and the least frequently volunteered.
It works as a ceiling rather than a fixed price. The mover weighs the shipment and calculates the actual charges as they would under a non-binding estimate. If those charges come in below the estimate, you pay the lower figure. If they come in above it, you pay the estimate and nothing more. You keep the savings when you ship less, and you are insulated when the surveyor guessed low.
There is no downside to the customer, which is precisely why it is not offered by default. Not every carrier will write one, and the ones that do usually require a solid physical or video survey first, since they are absorbing all of the estimating risk. But the request costs you nothing. When you contact movers, ask the question directly: “Do you offer a binding not-to-exceed estimate, and can you put that in writing?” The answer alone tells you a lot about the carrier you are dealing with.
How to Tell Which One You Actually Have
The estimate type is required to be stated on the estimate itself, but it is easy to miss among the tariff language. Check these five things before you sign anything:
- Find the words. Look for a checkbox or a heading reading “Binding Estimate,” “Non-Binding Estimate,” or “Binding Not-to-Exceed.” If none of those words appear anywhere on the document, treat it as non-binding — and ask for a corrected version.
- Check for an attached inventory. A binding estimate without an itemized inventory is nearly meaningless, because there is no agreed definition of what the price covers.
- Confirm it is signed by the mover. An estimate that only you have signed is a request, not an agreement.
- Look for the estimated weight. Every legitimate long-distance estimate shows an estimated shipment weight. If it is missing, the number at the bottom was not built from anything you can verify.
- Match it against the bill of lading on moving day. The bill of lading is the actual contract. If its terms differ from the estimate, do not sign until the discrepancy is explained and corrected on the spot.
One more document deserves mention. For interstate moves, movers are required to give you the FMCSA consumer booklet Your Rights and Responsibilities When You Move, along with information about their dispute-resolution program. Receiving those materials is a baseline sign of a compliant carrier; not receiving them is a meaningful red flag on its own.
Getting an Estimate That Actually Holds
The accuracy of any estimate — binding or not — comes down to the quality of the survey behind it. A price built on a five-minute phone call is a guess wearing a suit. These steps are what separate a quote that holds from one that unravels:
- Insist on a physical or video survey. A walkthrough, in person or over video, is the single biggest driver of estimate accuracy. Phone-only quotes for a full household are where the worst surprises are born.
- Open every door during the survey. Garage, attic, basement, crawlspace, closets, shed, storage unit. Undisclosed space is undisclosed weight, and undisclosed weight is where a comfortable estimate turns into a painful invoice.
- Describe both ends honestly. Stairs, elevator reservations, narrow streets, gated communities, parking restrictions, and long walks from the curb are all chargeable access conditions. Disclosing them upfront gets them priced into the estimate; discovering them on the day gets them added to it.
- Get everything in writing, including the extras. Packing materials, crating, appliance servicing, storage-in-transit, shuttle service, and valuation coverage should each appear as a line item, not as a verbal “we’ll take care of it.”
- Decide on valuation before moving day. Basic released-value protection is included at roughly 60 cents per pound per article, which is far below replacement cost for most items. Full-value protection costs more and should be priced in the estimate rather than sold to you at the door.
- Collect at least three written estimates. A single quote has no context. Three quotes for the same inventory reveal both the market rate and any outlier — and an unusually low bid on a non-binding estimate is often the one that grows the most.
Local and Intrastate Moves Work Differently
Everything above governs interstate household moves, which fall under federal FMCSA rules. A move that begins and ends inside the same state is regulated by that state — typically a state DOT, public utilities commission, or similar agency — and the rules vary considerably from one state to the next.
Local moves are also usually priced differently. Instead of weight and distance, they are billed by crew hours: a stated hourly rate, a minimum number of hours, and often travel or drive time on each end. In that structure, “binding” usually shows up as a flat-rate quote for the whole job rather than as the formal estimate types described above.
The underlying question does not change, though. Ask whether the number you have been given is a flat rate for the job or an hourly estimate that will be trued up at the end, and get the answer in writing. On an hourly move, also ask what the minimum is, when the clock starts and stops, whether travel time is billed, and what the overtime rate is after a certain hour — those four answers explain most of the gap between a local quote and a local invoice.
What to Do If a Mover Demands More Than the Estimate Allows
Even with a compliant estimate in hand, disputes happen — a driver who wants cash before unloading, a bill that blows past the 110 percent cap, or a binding estimate that mysteriously grew overnight. Federal rules give you specific leverage in each situation, and knowing it before moving day is what keeps a dispute from turning into your furniture being held hostage in the truck.
| Situation | Your Right | What to Do on the Spot |
|---|---|---|
| Non-binding bill exceeds 110% of estimate | Mover cannot require more than 110% at delivery | Pay only the capped amount; get the shortfall itemized in writing before the truck is unloaded |
| Binding estimate raised with no changed items | Price is fixed unless the job itself changed | Point to the signed estimate; refuse to sign a new one under pressure at the door |
| Driver refuses to unload without extra cash | This is the hostage-load pattern the 110% rule exists to prevent | Document everything, pay only what is legally owed, and file a complaint the same day |
| Damaged or missing items discovered later | You have 9 months to file a written claim for loss or damage | Photograph the damage, note it on the delivery paperwork, and file with the mover in writing |
If a dispute cannot be resolved with the driver directly, every FMCSA-registered interstate mover is required to participate in an arbitration program for claims up to $10,000 — ask for the arbitration paperwork by name, since it rarely comes up unprompted. For complaints about licensing, pricing practices, or a company that will not cooperate, file with the FMCSA's National Consumer Complaint Database at nccdb.fmcsa.dot.gov, which regulators use to track patterns across a carrier and can support a chargeback if you paid by credit card.
Red Flags Worth Walking Away From
- A quote given over the phone with no survey, for a full house. Nobody can price a three-bedroom home accurately without seeing it.
- A large deposit demanded upfront. Reputable movers typically collect on delivery. A big cash or wire deposit before anything is loaded is a well-known pattern in moving scams.
- Blank spaces on the paperwork. Never sign an estimate or bill of lading with empty fields. They can be filled in later, and not in your favor.
- No USDOT number, or one that does not check out. Interstate movers must have one, and it should be verifiable and match the company name on your paperwork.
- A price dramatically below every other bid. On a non-binding estimate especially, the lowball quote is frequently the one that arrives 30 percent higher at the door.
- Reluctance to identify the estimate type in writing. If a company will not state plainly whether its quote is binding, you already have the answer you need about that company.
Frequently Asked Questions
What is the difference between a binding and non-binding moving estimate?
A binding estimate is a fixed price for the inventory and services listed — you pay the quoted figure regardless of what the shipment weighs. A non-binding estimate is a projection; the final bill is calculated from the actual weight after the truck is scaled, so it can land above or below the quote. On interstate moves, a mover cannot require more than 110 percent of a non-binding estimate at delivery, but the balance is still owed and billed within 30 days.
How does the 110 percent rule work?
It caps what you must pay before your goods are released, not what the move costs. On a $4,000 non-binding estimate with $4,800 in actual charges, the driver can collect at most $4,400 at delivery — and the remaining $400 is invoiced within 30 days. It exists to keep your belongings from being held hostage over a bill you were not expecting, not to limit the total.
Is a binding estimate always the better choice?
Usually, but not universally. Binding quotes carry a small risk cushion, so they can start slightly higher. If your inventory is settled and you need a budgetable number, that is worth paying for. If you are still purging aggressively and expect to ship well under what was surveyed, a non-binding estimate lets you keep the savings. Just never accept a binding estimate written from a vague inventory.
What is a binding not-to-exceed estimate?
A ceiling rather than a fixed price: you pay the lesser of the actual charges or the estimate. If the shipment weighs less than surveyed you pay less; if it weighs more you still pay only the estimate. It is the most consumer-friendly option available and is rarely offered unprompted, so ask for it by name.
Can a mover change a binding estimate on moving day?
Only if the job changes — added items, added services, or access conditions that were not disclosed. In that case the mover must either reissue a revised binding estimate for you to sign before loading, or convert the move to tariff-based charges. Loading under the original estimate and demanding more at delivery for the same job is not permitted, and your signed paperwork is the proof.
The Bottom Line
Moving quotes are not commodities, and two numbers that look the same on paper can behave very differently once a truck is on a scale. Before you compare prices across carriers, compare structures: a $4,200 binding not-to-exceed estimate is a fundamentally better deal than a $3,900 non-binding one, even though the second number is smaller, because only one of them tells you what you will actually pay.
Ask which type you are being given. Get it in writing. Make sure an itemized inventory is attached, that the survey was thorough, and that every extra service appears as its own line. Then compare several quotes built the same way — because the widest variation in moving costs is not between estimate types at all. It is between companies quoting the exact same job.
