Binding vs. Non-Binding Moving Estimates

A binding estimate is exactly what it sounds like: the carrier reviews your inventory (in-person, video, or detailed list), commits to a price in writing, and that price holds whether your shipment ends up weighing slightly more or slightly less than estimated. The only way the number changes is if you add items or trigger an accessorial. For most households this is the lowest-stress option because you can budget the move down to the dollar.

A binding not-to-exceed (sometimes called "guaranteed-not-to-exceed") estimate caps the upside while keeping the downside. The carrier surveys your home, quotes you a maximum, and on move day the truck is weighed on a certified CAT scale at both empty and loaded weight. If the actual weight comes in lower, you pay less; if it comes in higher, you still only pay what's on the estimate. Reputable national van lines (United, Mayflower, Allied, North American, Atlas) routinely offer this. It's the safest contract a customer can sign.

A non-binding estimate is a good-faith guess. Under federal rule 49 CFR § 375.405, the carrier can collect up to 110% of the estimate at delivery, with any remaining balance due within 30 days on credit terms. That sounds protective, but the math is brutal: a $6,000 estimate can turn into $6,600 at the doorstep, payable before the crew unloads. If the re-weigh comes in well above estimate, you can fall into a "hostage load" situation. Non-binding is fine for movers you already trust, but treat it as a ceiling, not a quote.

For any interstate household-goods shipment, the carrier or broker is required by federal regulation to (a) provide a written estimate before pickup, (b) base it on a visual or video survey unless you waive that right in writing, (c) hand you the FMCSA "Your Rights and Responsibilities When You Move" booklet, and (d) disclose whether they are operating as the carrier or as a broker. If any of those steps are skipped, the contract is on shaky ground.

Even a binding estimate can grow if you add boxes after the quote, the crew finds a flight of stairs the estimator didn't see, the 53-ft trailer can't reach the door and needs a shuttle truck, or pickup or delivery is delayed enough to trigger storage-in-transit. In every case, federal rules require a written change order that you sign before the carrier performs the added service. Don't accept verbal "this is going to cost more" updates — demand the revision on paper.

When you talk to an estimator, ask one specific question: "Is this estimate binding, binding-not-to-exceed, or non-binding?" If they answer anything other than one of those three terms, they don't understand federal rules and you're talking to the wrong company.
