Binding vs. Non-Binding Moving Estimates: What's the Difference?
If you are planning an interstate move, understanding binding vs. non-binding moving estimates can keep you from comparing quotes that do not mean the same thing. A binding estimate generally guarantees the price for the household goods and services listed in the estimate. A non-binding estimate is an approximation, and the final transportation charges can change based on the actual shipment and services provided.
That sounds simple, but there is an important catch. A binding estimate does not give you unlimited freedom to add furniture, boxes, packing, stops, or other services without affecting the agreement. A non-binding estimate also does not give a mover unlimited freedom to charge whatever it wants.
For federally regulated interstate household-goods moves, Federal Motor Carrier Safety Administration rules spell out how both types of estimates work. eCFR
What Is the Difference Between a Binding and Non-Binding Moving Estimate?
The main difference is whether the estimated price is guaranteed for the scope listed in the document.
Under federal rules, an interstate mover must provide a written estimate before the bill of lading is executed and identify whether the estimate is binding or non-binding. A binding estimate guarantees the total cost based on the quantities and services shown. A non-binding estimate is the mover's reasonably accurate projection of the cost, with final charges based on the shipment and applicable services. eCFR
Question | Binding Estimate | Non-Binding Estimate |
Is the estimated price guaranteed? | Generally yes, for the listed goods and services | No |
Can added items affect the agreement? | Yes | Yes |
Can added services affect the price? | Yes | Yes |
Does actual shipment weight affect the original covered price? | Generally no | Yes |
Amount generally due for estimated charges at delivery | Binding amount | Up to 110% of the non-binding estimate |
Can separately permitted additional charges apply? | Yes | Yes |
The important phrase is listed goods and services. The estimate needs to reflect the move you are actually asking the company to perform.
What Does a Binding Moving Estimate Actually Cover?
A binding estimate can give you more price certainty, but only when the scope of the move is accurate.
Federal regulations require a binding estimate to describe the shipment and the services the mover will provide. The document must also state that the charges shown apply only to the services specifically identified in the estimate. eCFR
The Inventory Matters as Much as the Price
Suppose one mover quotes a lower amount but the estimate leaves out garage contents, packing work, an extra pickup, or known access conditions. Another mover may quote more because those items are already included.
Those two estimates are not necessarily comparable.
Before accepting a binding estimate, check whether the mover understands the full move, including furniture, cartons, storage areas, packing needs, stairs, elevators, truck access, additional stops, and any items needing special handling.
This is why a thorough survey matters. For interstate household-goods moves, federal rules generally require a physical survey unless the customer waives the survey requirement in writing. FMCSA also explains that this inspection can be conducted in person or virtually. eCFR
What Happens If You Add Items Before Loading?
This is where many consumers misunderstand the word "binding."
If you present additional household goods or request services that were not included in the original binding estimate, the mover is not automatically required to perform the expanded move for the original price.
Before loading, federal rules allow the mover and customer to reaffirm the original binding estimate, prepare a new binding estimate, or agree in writing to treat the original estimate as non-binding. If the shipment is loaded without a new estimate or written conversion, the original binding estimate is generally reaffirmed, subject to the federal rules for certain later services and impracticable operations. eCFR
The practical lesson is straightforward. If your inventory changes, tell the mover before loading begins.
How Does a Non-Binding Moving Estimate Work?
A non-binding estimate is not a guaranteed final price. It is supposed to be a reasonably accurate estimate of what the customer should expect to pay.
Federal rules require the estimate to describe the shipment and services. The mover must also explain that final charges may exceed the amount shown on the estimate and that final transportation charges are based on the applicable tariff, shipment and services. eCFR
For many non-binding interstate moves, actual shipment weight is an important part of the final calculation.
What Is the 110% Rule?
The 110% rule is one of the most misunderstood protections in interstate moving.
For a collect-on-delivery interstate shipment moving under a non-binding estimate, federal rules generally require the mover to release the shipment when the customer pays up to 110% of the non-binding estimate, along with certain permitted additional charges that may apply. eCFR
For example, if the non-binding estimate is $5,000, 110% is $5,500.
That does not necessarily mean $5,500 is the maximum final bill.
The 110% rule primarily limits how much of the original estimated transportation charges can generally be required at delivery. Federal rules provide for billing and collection of applicable amounts that were not collected at delivery. Separately authorized services requested after the bill of lading and qualifying impracticable-operation charges can also be treated differently under the regulations. eCFR
So if you see someone describe the 110% rule as "your final bill can never be more than 110% of the estimate," that is too broad.
Can a Non-Binding Estimate Be Changed Before Loading?
Yes, when the shipment changes.
If you tender additional household goods or need additional services that were not included, the mover may reaffirm the original non-binding estimate or prepare a new non-binding estimate before loading. The new estimate must accurately include the added goods or services and be signed by the customer. eCFR
Once again, good estimating starts with good information.
What Can Cause a Moving Estimate to Change?
Many estimate disputes begin because the move described during estimating is different from the move presented on moving day.
Common changes include more boxes than originally disclosed, furniture that was supposed to stay behind, garage or storage contents, added packing, an additional pickup, or other services that were not part of the original scope.
Access can matter too. Stairs, elevators, long carries, loading areas, gated access, and the distance between the truck and the residence can affect the work required. Federal regulations specifically require interstate movers to determine charges for known accessorial services such as elevators and long carries before preparing the bill of lading. eCFR
That is why the cheapest number on a page should not be the only thing you compare.
Give the Mover the Whole Picture
Before the estimate is finalized, walk through the move carefully.
Show the mover closets, patios, garages, sheds, storage spaces, and rooms that may be easy to overlook. Discuss what you are packing yourself and what you expect the crew to pack. Explain stairs, elevators, gates, loading areas, and destination conditions you already know about.
If something changes later, communicate it before moving day when possible.
A professional estimate works best when both sides are working from the same inventory and service plan.

Do Binding and Non-Binding Estimate Rules Apply to California Local Moves?
This distinction matters for My Dad's Moving customers because California intrastate moves and interstate moves do not use the same regulatory framework.
A move from Morgan Hill to San Jose, Gilroy, Sacramento, or Los Angeles stays within California. A move from Morgan Hill to Nevada, Arizona, Oregon, Texas, or another state is generally an interstate move.
For moves within California, the California Bureau of Household Goods and Services requires a written estimate after a visual inspection and requires the moving agreement to include a Not to Exceed Price, which is the maximum amount the mover may charge unless permitted changes are documented through the applicable process. Bureau of Household Goods and Services
For moves into or out of California, BHGS also tells consumers to note whether the estimate is binding or non-binding, while federal interstate rules govern those estimate structures. Bureau of Household Goods and Services
Do not assume that terminology from an interstate estimate automatically applies the same way to a local California move. Ask which rules apply to your specific origin and destination.
Which Type of Moving Estimate Is Better?
A binding estimate can make budgeting easier because it fixes the charge for the goods and services covered by the estimate. That can be useful when the inventory, services, and access conditions are clearly known.
A non-binding estimate can still be legitimate and useful, but you need to understand how the final charges will be calculated.
The label alone does not tell you whether an estimate is good.
A detailed, realistic estimate from a mover that understands the job can be more useful than a low number built from incomplete information.
Before you sign, make sure you can answer four questions:
Is the estimate binding or non-binding?
What household goods and services are included?
What circumstances could result in additional charges?
What amount and payment method will be required at delivery?
If the paperwork does not make those points clear, ask questions before the truck is loaded.
For customers planning local or long-distance moves, My Dad's Moving Inc. provides local and long-distance moving services from Morgan Hill and throughout South County, San Jose, and the Bay Area, with long-distance delivery across the continental United States.
Conclusion: Understand the Estimate Before Moving Day
The difference between binding and non-binding moving estimates comes down to price commitment and scope.
A binding interstate estimate generally guarantees the agreed charge for the household goods and services listed in the estimate. A non-binding estimate is a reasonably accurate projection, and the final charge can change based on the shipment, services provided, and applicable tariff.
Neither type of estimate works well when the mover does not have an accurate picture of the job.
Before moving day, make sure your inventory is complete, discuss packing and special handling, disclose known access conditions, and review the written estimate carefully. If something changes, tell the mover before loading.

Frequently Asked Questions
What is a binding moving estimate?
For a federally regulated interstate household-goods move, a binding estimate generally guarantees the total charge for the quantities and services identified in the written estimate. If you add goods or services, the estimate may need to be reaffirmed, replaced, or otherwise handled under federal rules before loading. eCFR
Can a mover charge more than a binding estimate?
Additional goods or services can change the agreement, and federal rules also address certain services requested or required after the bill of lading is issued. A binding estimate should not be described as an unlimited fixed price regardless of changes to the move. eCFR
What is the 110% rule for moving estimates?
For a collect-on-delivery interstate shipment under a non-binding estimate, the mover generally cannot require more than 110% of the non-binding estimate for the original estimated charges at delivery, subject to separately permitted additional charges. The rule does not necessarily cap the ultimate final bill at 110%. eCFR
Is a binding estimate better than a non-binding estimate?
Not automatically. A binding estimate can provide stronger price certainty, but the quality of the inventory, service description, access information, and estimating process still matters.
Do binding and non-binding estimates apply to California local moves?
The federal binding and non-binding estimate rules discussed here apply to federally regulated interstate household-goods transportation. Moves performed entirely within California are governed by California requirements, including the state's Not to Exceed Price framework. Bureau of Household Goods and Services
