A non-binding moving estimate is a written cost projection — not a guaranteed price. The mover surveys your belongings, calculates an expected weight and service cost, and gives you a number, but the final bill is based on what the move actually weighs and what services are actually performed. Under FMCSA rules for interstate moves, a mover cannot require you to pay more than 110% of a non-binding estimate at delivery — you have 30 days after delivery to pay any amount above that 110% threshold.
That one rule — the 110% protection — is the thing most customers never hear about until they're staring at a bill that's $400 higher than the quote. Let's walk through how non-binding estimates work, where they break down, and how to get one that's actually useful.
What is a non-binding moving estimate, exactly?
A non-binding estimate is a mover's best-faith prediction of what your move will cost, based on the inventory they survey — either in person, by video, or over the phone. It is not a contract price. The final bill is calculated after your shipment is weighed on certified scales, and the actual weight × the tariff rate + any additional services = what you owe.
Non-binding estimates are the most common quote type for long-distance moves. They're legal, standard, and fine — as long as you understand what they are and what protections apply.
For a direct comparison with the alternative, see our guide to binding vs. non-binding moving estimates, which breaks down exactly which type fits which kind of move.
How does a non-binding estimate become a final price?
Here's the step-by-step process for an interstate move:
- Mover surveys your inventory — in person, via video walk-through, or over the phone. Accuracy here determines how close the estimate will be to reality.
- Mover issues a written estimate — FMCSA requires it to be in writing and to state clearly that it is non-binding.
- Shipment is weighed — the loaded truck is weighed on a certified scale (the "origin weight"), then weighed again after unloading (the "destination weight"), or a single certified scale weight is taken. You have the right to observe this weigh-in.
- Actual charges are calculated — weight × tariff rate + fuel surcharges + accessorial fees (stairs, long carry, shuttle, etc.).
- At delivery, you pay — under federal rules (49 CFR Part 375), you cannot be required to pay more than 110% of the non-binding estimate at the time of delivery. Any overage above 110% must be billed and collected within 30 days.
| Estimate Type | Final Price Locked? | Max Due at Delivery | FMCSA Regulated? |
|---|---|---|---|
| Non-binding | No | 110% of estimate | Yes (interstate) |
| Binding | Yes | Exactly the estimate (unless you add services) | Yes (interstate) |
| Binding not-to-exceed | At or below estimate | At or below estimate | Yes (interstate) |
Does the 110% rule apply to all moves?
Only for interstate (state-to-state) moves. The FMCSA regulates movers that operate across state lines. For local (intrastate) moves, the rules depend on your state's Public Utilities Commission or Department of Transportation — and most states do not have a hard statutory cap equivalent to the federal 110% rule.
- California: Regulated by the CPUC. Movers must honor estimates within specific windows.
- New York: Regulated by the NYSDOT. Rules vary by move type.
- Texas, Florida, and most others: Lighter state regulation; review your written contract carefully.
If you're moving locally, the 110% rule does not automatically apply. Read your estimate and contract carefully — and ask the mover directly what happens if the weight comes in higher than projected. For more on what rights you have under federal law, read our guide to what FMCSA rules require movers to tell you.
Why non-binding estimates come in higher than expected
We've been in this business long enough to have seen every version of this conversation: a customer calls, upset that the final bill is $600 over the estimate. In most cases, it traces back to one of these causes:
- Inventory wasn't complete at survey time. The customer forgot the garage, the attic, or the items in the storage closet. More stuff = more weight = higher bill.
- The estimate was done by phone without a proper inventory. Phone-only estimates are less accurate than in-person or video surveys. If a mover gives you a quote in 90 seconds without asking about your furniture piece by piece, it will be wrong.
- Accessorial services weren't included. A long carry (when the truck can't park close to the door), stair carries, elevator waits, and shuttle fees are real charges — and they're sometimes left off an initial estimate. Our guide to moving hidden fees and surcharges covers every one of these line items.
- You added items on moving day. Anything loaded that wasn't on the original inventory can push weight — and cost — up.

How to get a non-binding estimate that actually holds
The estimate is only as good as the inventory behind it. Here's how to protect yourself:
- Request an in-person or video survey. A mover who won't survey before quoting is a mover whose estimate you cannot trust.
- Walk through every room, closet, garage, and outdoor space. Don't leave anything out. It's better to have an accurate high estimate than a pleasant low estimate that turns into a shock at delivery.
- Get everything in writing. FMCSA requires the estimate to be written and signed. Do not accept a verbal quote for an interstate move.
- Ask what's not included. Specifically ask: "Are there any services — stairs, long carry, shuttle, packing materials — that would add charges not reflected in this estimate?" Get the answer in writing.
- Ask for a weight-based breakdown. A legitimate estimate will show you the estimated weight and the rate per hundred pounds (the "cwt" rate). If it just shows a lump sum with no weight projection, push back.
- Request to observe the weigh-in. You have a legal right to witness the weighing of your shipment on an interstate move. Exercise it if cost is a concern — it keeps everyone honest.
- Compare multiple estimates. Three estimates from verified mover reviews on this directory give you a baseline; the outlier — high or low — deserves scrutiny.
What to do when the final bill is higher than the estimate
If you're at delivery and the bill is more than 110% of your non-binding estimate on an interstate move:
- You are only required to pay 110% at delivery. The mover must release your goods upon payment of that amount. They cannot hold your shipment hostage for the full amount due.
- Get the overage in writing. The mover has 30 days to bill you for the remainder.
- Dispute the weight if you believe it's wrong. You can request a reweigh before delivery. If the reweigh shows a lower weight, the lower weight is used for billing (and you pay the cost of the reweigh only if the weight goes up, in most cases — confirm this in your contract).
- File a complaint with FMCSA. Use the FMCSA's National Consumer Complaint Database at protectyourmove.gov. For intrastate disputes, contact your state PUC or DOT.
- If items are damaged, file a claim separately. The overage dispute and a damage claim are handled through different channels. See our step-by-step guide on how to file a moving damage claim if you need to go that route.
Non-binding vs. binding: which should you choose?
If cost predictability matters most to you — and it usually does — a binding estimate or binding not-to-exceed estimate is worth asking for. A binding estimate locks the price; a binding not-to-exceed means you pay no more than the estimate but could pay less if the shipment weighs less than projected.
Non-binding estimates aren't bad — they're the industry standard, and for moves where your inventory is hard to pin down exactly, they're often practical. The key is knowing the rules before you sign.

Frequently asked questions
Can a mover legally refuse to deliver my stuff if I won't pay over the estimate?
On an interstate move, no — not if you've paid 110% of the non-binding estimate. Under 49 CFR Part 375, a mover must release your shipment upon payment of that 110% amount at delivery. The remaining balance (if any) is billed separately and must be paid within 30 days. A mover who refuses delivery after receiving 110% is violating federal law and can be reported to FMCSA.
Is a non-binding estimate the same as a quote?
The words are often used interchangeably, but technically a "quote" can be either binding or non-binding. Always ask which type you're receiving and confirm in writing. A non-binding estimate must be labeled as such under FMCSA rules for interstate movers.
Does the 110% rule apply to local moves within the same state?
No. The 110% rule is a federal FMCSA rule that applies only to interstate (state-to-state) moves. For intrastate (in-state) moves, your state's transportation regulator sets the rules — and most states don't have an equivalent cap. Review your contract and ask the mover directly what their policy is.
Can I negotiate a non-binding estimate into a binding one?
Yes, in many cases. After receiving a non-binding estimate, you can ask the mover to convert it to a binding estimate — typically for the same or slightly higher amount, since the mover now carries the weight risk. Not all movers offer this, but it's always worth asking, especially for large or complex moves.
What happens if my shipment weighs less than the estimate?
With a non-binding estimate, if the actual weight comes in lower, you pay the lower amount — that's one of the benefits of non-binding. With a standard binding estimate, you pay the agreed price regardless of actual weight. With a binding not-to-exceed estimate, you pay the lower of the estimated or actual price.
How far in advance should I get a moving estimate?
For interstate moves, we recommend getting estimates at least 6–8 weeks before your move date, and locking in your mover 4–6 weeks out. If you're moving during peak season (May through September), push those timelines earlier. You can find movers on our directory and request estimates directly — and our AI agent Robert can help you figure out what questions to ask before you commit to anything.
