Binding, non-binding, and not-to-exceed: how to read a moving estimate before you sign anything

Why the estimate type determines your exposure

Most consumers treat a moving estimate as a rough number to compare across companies. It is actually a document that establishes the legal basis for pricing your move — and the three estimate types work under different rules, protecting you differently when the actual weight or service requirements differ from what was originally quoted.

Federal regulation 49 C.F.R. Part 375 governs estimates for interstate household goods moves and establishes the legal definitions of each type. For intrastate moves, state-level regulations apply, but most states follow the same framework. Every time you compare two estimates side-by-side, the comparison is only meaningful if both estimates are the same type. A $4,800 binding estimate and a $4,200 non-binding estimate are not the same offer — the non-binding one could end up higher at delivery depending on the actual weight of your shipment.

Understanding the type of estimate you're receiving before you sign is the single most important step in protecting yourself from a surprise bill on moving day.

Non-binding estimates: the flexible-price model

A non-binding estimate is the mover's best assessment of what your move will cost based on the surveyed inventory, but the final price is determined by the actual weight of the shipment. Because weight is measured at the destination or at a certified weigh station, not at the pickup address, the final bill can be higher or lower than the estimate.

Under federal rules (49 C.F.R. Part 375.213), the mover cannot require you to pay more than 110 percent of the non-binding estimate at the time of delivery. If the actual charges come out to 125 percent of the estimate, you pay the 110 percent limit on delivery day and have 30 days to pay the balance. This rule is called the "110 percent rule," and it is a consumer protection, not a cap — the mover can collect the full actual charges, just not all at once on delivery day if the bill exceeds 110 percent.

Non-binding estimates work in your favor when the actual weight comes in below the estimate — you pay only what the actual charges support. They work against you when the actual weight is higher than estimated, which happens most often when the pre-move survey was conducted by phone or video without a thorough walkthrough of heavy items like pianos, safes, or full bookshelves.

When accepting a non-binding estimate, ask the surveyor to document every room explicitly, including weight-dense items that are easy to overlook. A thorough pre-move survey is the best defense against a non-binding estimate that surprises you at delivery.

Binding estimates: the locked-price model

A binding estimate fixes the price of the move in advance, regardless of what the shipment actually weighs. If the mover estimated 6,200 pounds and your goods weigh 7,800 pounds on the scale, you pay the binding price — the mover absorbs the difference. If the goods come in lighter at 5,400 pounds, you still pay the binding price.

This makes binding estimates straightforward to manage financially — you know your maximum exposure before the truck arrives. The risk is on the other side: if the estimate was based on an incomplete survey and your actual inventory is larger, the mover may legitimately refuse to move additional items that weren't included in the original binding estimate without a revised binding estimate and your written agreement.

Under federal rules, a mover cannot charge more than the binding amount at delivery for the services listed on the estimate. If additional services are required that weren't on the original estimate — for example, a shuttle truck because the main truck cannot park close enough to the door — those are billed separately as add-ons, not folded into the binding total.

The practical implication: read the binding estimate carefully for what it includes and excludes. A binding estimate that excludes fuel surcharges, stair fees, and long-carry charges is not actually binding you to the total you think it is — it's binding the labor and transport cost, with the excluded line items still floating.

Not-to-exceed estimates: the consumer-friendly hybrid

A not-to-exceed estimate (sometimes called a "guaranteed not-to-exceed" or GNTE) combines the price certainty of a binding estimate with the upside of a non-binding one. The estimate establishes a ceiling — you will never pay more than the stated amount — but if the actual weight is lower than estimated, you pay based on the lower actual weight.

Not-to-exceed is the estimate type explicitly recommended in the FMCSA's consumer guidance pamphlet "Your Rights and Responsibilities When You Move," which every interstate mover is legally required to provide before your move. The asymmetry is favorable to consumers: you are protected against over-runs, but you benefit if your shipment comes in lighter.

Not all movers offer not-to-exceed estimates — it's a business choice, not a federal requirement. Some companies offer it as a standard option; others only offer it on request; others don't offer it at all. When getting quotes, specifically ask whether a not-to-exceed option is available and how it's priced compared to the standard non-binding estimate. The premium for a not-to-exceed is often smaller than you'd expect, because the mover's exposure only runs in one direction.

If a mover doesn't offer not-to-exceed but you're concerned about weight overruns, a binding estimate achieves the same ceiling — at the cost of giving up the upside if the shipment comes in lighter.

What to look for in the estimate document itself

Before you agree to any estimate, read the document against this checklist. Each item is either required by federal regulation or is a frequent source of post-move disputes.

The estimate type must be stated explicitly. The words "binding," "non-binding," or "not-to-exceed" should appear on the document. If they don't, ask in writing which type applies to your move.

The pickup and delivery addresses should be listed. An estimate without a confirmed delivery address is incomplete, because distance is a component of the pricing formula.

The inventory list should match what was surveyed. Walk through it room by room. Missing items mean your actual weight may exceed the estimate, and no binding protection applies to items that weren't included in the original survey.

The services included in the price should be itemized. Packing, unpacking, disassembly, reassembly, specialty handling (piano, art, antiques), and storage-in-transit are all separate line items that may or may not be included. The estimate total is only meaningful relative to the scope of services it covers.

The pickup and delivery windows should be stated. For long-distance moves, the delivery window is often a range of days. You have the right to know the window before you sign; a moving company that will not commit to a delivery window in writing is a risk.

Any "subject to survey" language should be treated with caution. This language means the price could change after the mover completes an in-home review. It's legitimate if the phone survey was preliminary — but it means you do not yet have a real estimate.

The FMCSA pamphlet every mover must give you

Under 49 C.F.R. Part 375.213, every interstate moving company is legally required to provide you with a copy of "Your Rights and Responsibilities When You Move" before accepting your business. This pamphlet, produced by the FMCSA, covers estimate types, valuation options, claims procedures, and your rights under federal law. If a mover has not offered it to you, ask for it — and treat the refusal as a warning sign.

The pamphlet is also available directly from the FMCSA website at fmcsa.dot.gov. Reading it before you receive your first estimate puts the legal framework in context, so the terms on the estimate document are not new to you when you encounter them.

The pamphlet matters because it establishes the baseline of what the law requires from movers, which is the context you need to evaluate what a given mover's terms actually say. A mover whose terms are significantly more favorable than the legal minimum is a better deal; a mover whose terms are at or below the legal minimum is doing the least the law requires.

What happens when the estimate needs to change

Estimates can legitimately be revised before the move for two reasons: you change the inventory (you acquired furniture, you're taking items you originally said you wouldn't move), or the mover discovers items during the in-home survey that weren't captured in an initial phone or video walkthrough.

If you add items after a binding estimate has been issued, you and the mover must agree to a revised binding estimate in writing before the truck is loaded. The mover is not obligated to move items outside the original binding estimate at the original price. This is why the inventory list on the estimate document matters — it defines what the price covers.

For non-binding estimates, the weight of added items is captured at the weigh station and the final charge adjusts accordingly. There is no separate revised estimate required because the estimate was never a fixed-price commitment.

If a mover attempts to revise a binding estimate after the truck is loaded, that revision is not valid unless you agree to it in writing before delivery. A binding estimate revised at delivery is a red flag, not a routine administrative adjustment.

How to compare three estimates without making the obvious mistake

Getting three estimates is the right approach — but comparing them at the headline number misses the point. Here is how to actually compare.

First, normalize the estimate type. Compare binding to binding, non-binding to non-binding, or not-to-exceed to not-to-exceed. A binding estimate is a maximum; a non-binding estimate is a variable. They are not equivalent even at the same number.

Second, compare the scope. Are packing materials included or excluded? Is the valuation coverage the same? Does one estimate include a stair fee that another has left off the sheet? The survey that captured more detail is generally more reliable; the estimate that excludes more line items has more room to grow.

Third, verify the estimated weight. Ask each company how they arrived at their weight estimate and compare the figures. If two companies estimate 6,500 pounds and one estimates 4,800 pounds for the same inventory, the lower estimate may be incomplete rather than more competitive.

Fourth, check the delivery window. A mover quoting a pickup in three weeks but a delivery window of "10-20 business days" is offering materially different service from one guaranteeing delivery within five business days, even at the same price.

A moving concierge or consumer advocate familiar with interstate tariff structures can review estimates side-by-side and flag discrepancies in scope that would otherwise require reading the fine print of each estimate independently.

When the final bill at delivery differs from your estimate

If you have a binding estimate and the mover presents a higher bill at delivery, you are not required to pay the difference to take possession of your goods — assuming the added charges are for services included in the original estimate. For services genuinely outside the original scope (a shuttle truck that became necessary because of an access issue you didn't disclose), the add-on is legitimate and you should have been informed before those services were performed.

If you have a non-binding estimate and the bill at delivery exceeds 110 percent of the estimate, the mover must allow you 30 days to pay the amount above 110 percent. They cannot withhold your goods pending immediate payment of the full overage. If they do, that is a violation of federal regulation, and you should contact the FMCSA at 1-888-368-7238 and file a complaint.

Document the bill of lading at delivery before signing. Note any discrepancies between the estimate and the final bill on the delivery receipt. Once you sign the delivery receipt without noting objections, it is harder — though not impossible — to dispute charges after the fact.
