Binding vs Non-Binding Moving Estimates: What US Customers Should Know
Binding vs non-binding moving estimate rules decide who eats an overage on moving day. FMCSA interstate rules favour the customer on one type only.
What to take away
- A binding estimate locks the price for the listed services. The mover cannot charge more unless you add services or the inventory was wrong.
- A non-binding estimate is a good-faith guess. On interstate moves the final bill can exceed it by no more than 10 percent before delivery, under the FMCSA 110 percent rule.
- Non-binding estimates require payment of the balance within 30 days after delivery for the amount above the estimate.
- Binding estimates cost you flexibilityextra items, added stairs or a changed date usually mean a new price.
- Ask which type is written on the estimate itself. If the word binding does not appear, treat it as non-binding.
The two documents being compared
Federal rules split household goods estimates into two forms. A binding estimate fixes the total for the specific services listed, and the mover must honour it even if the job takes longer. A non-binding estimate states an approximate cost based on weight and services, and the final charges are calculated from the actual weight and the mover's published tariff.
The FMCSA regulation for household goods movers sets out what each document must contain, including the type of estimate, the guaranteed charges and the basis for any non-binding figure. The agency's consumer page explains the difference in plainer terms at FMCSA protect your move.

Binding estimates, option by option
A binding moving estimate definition is simple: the mover guarantees a price for the work described. The number holds if the inventory sheet matches what gets loaded and the access conditions match what was surveyed. If you add a piano or the truck cannot reach the door, the guarantee usually lapses and the mover issues a new estimate.
This option wins when your inventory is settled, your dates are fixed and you want a number you can budget against. It also wins when you have quotes from several movers and want to compare them on equal terms.
Non-binding estimates and the 110 percent rule
Non-binding estimate rules are where most interstate disputes start. The mover weighs the shipment, applies its tariff and bills the result. If the actual weight runs higher than the estimate, the bill rises with it, but only so far before delivery.
The 110 Percent Rule
- 110% | maximum of estimate collectable before unloading
- 30 days | to pay the remaining balance after delivery
- 100% | of estimate is not a ceiling on final cost
Under the 110 percent rule, a mover may not demand more than 110 percent of the estimated charges before unloading. The remainder is billed later, and you have 30 days after delivery to pay it. That cap only applies when the estimate was given in good faith and the inventory was accurate.
A non-binding estimate is not a ceiling. It is a starting figure with a legal brake on how much cash the driver can ask for at the door.
Where each one wins
Non-binding suits a household that is still sorting, storing or selling items, because the final price follows the actual load. It also suits a move booked at short notice, when no survey has been done.
Binding suits a household with a firm inventory, a confirmed address and a moving date that will not shift. The trade is clear: you give up the ability to change the load without renegotiating.
For a state-level view of how these rules interact with intrastate tariffs, the comparison of California and Texas intrastate moving rules shows where federal and state regimes diverge.
What none of them solve
Neither estimate type covers services that were never listed. Long carries, shuttle trucks at buildings with no truck access, stair fees and packing materials are common additions, and they can appear on either document. The USA.gov moving guide points readers toward checking what is included before signing.
Neither type protects you from a lowball bid. A binding estimate built on an understated weight still binds the mover to that price, which is why some carriers simply refuse the job later. Reading the moving company contract terms that prevent disputes before signing is the cheapest protection available.
Example
A Texas household gets a non-binding estimate of 8,000 USD for a 1,200-mile interstate move. The shipment weighs more than the survey assumed. Before unloading, the driver may collect no more than 8,800 USD, which is 110 percent of the estimate. The remaining balance is invoiced and due within 30 days.
