Binding or non-binding estimate: which moving quote protects your budget?
A plain-English breakdown of binding, non-binding, and not-to-exceed estimates — what each one really guarantees, what can still change on moving day, and a quick document check to run before you sign.
A binding estimate locks the total price for the listed inventory and services; a non-binding estimate is an educated guess, and your final bill is based on the actual weight and services performed, with the mover limited to collecting 110% of the estimate at delivery. A binding not-to-exceed estimate sets a price ceiling that can drop if your shipment weighs less but cannot rise above it. The right choice depends on how settled your inventory is and how much budget certainty you need.
A moving estimate is a written document, not a verbal quote, that spells out what your move should cost based on what the mover sees during a survey. The estimate type you agree to decides who carries the risk if the shipment ends up heavier, lighter, or more complicated than planned. Federal rules for interstate moves govern how each estimate type must be presented and what a mover can collect at delivery; in-state moves may not give you the same protections, so check your state's rules too.
The three estimate types, in plain English
What each estimate type really means
Feature
Binding
Non-binding
Binding not-to-exceed
Price guarantee
Fixed total for listed items and services
Approximation only; not a contract
Hard ceiling; can drop but cannot rise
Can final bill change?
Only if the scope of the move changes
Yes, based on actual weight and services
Yes, downward only
What you pay at delivery
100% of the estimate
Up to 110% of the estimate, balance billed later
The capped amount (or less)
Inventory still changing?
Risky — additions can void the price
Flexible — pay for what you actually ship
Flexible — savings possible if you lighten the load
Best fit
Fixed inventories and strict budgets
Moves where weight is uncertain
Long-distance moves where you want a ceiling
The non-binding estimate is essentially the mover's educated guess. The final bill is calculated using the mover's published tariff rates and the actual weight of the shipment as measured at a certified scale, plus any accessorial services performed. Because the number can move in either direction, federal rules require the mover to give you a copy of the relevant tariff provisions so you can see how the final charges are built.
Comparing estimates side by side helps you see which type matches your inventory and budget tolerance.
What can still change the final bill
Triggers that can move the price on any estimate type
Added or removed items after the survey — can require a revised written estimate or void a binding price.
Accessorial services requested on moving day: packing, furniture disassembly, stairs, long carries, shuttle service for narrow streets.
Impracticable operations charges, capped at 15% of the other charges due at delivery on interstate moves.
Storage-in-transit if delivery is delayed and you cannot pay on arrival.
A change from binding to non-binding treatment, which must be put in writing before loading.
A binding estimate only protects you while the scope of the move matches the original plan. Adding a sleeper sofa, requesting packing on moving day, or discovering the driveway cannot fit the truck can each require a revised estimate or a written addendum. If the mover loads the truck without updating the paperwork, the original binding estimate is generally reaffirmed, and the mover cannot collect more than that amount (except for agreed additional services and impracticable operations charges).
A not-to-exceed estimate sets a ceiling on the bill — useful when you want protection but expect to trim your inventory.
How to read any estimate before you sign
Document review method for any moving estimate
✓
Confirm the type on the face of the document
It should clearly say binding, non-binding, or not-to-exceed. If the type is missing or only appears in fine print, ask the mover to rewrite it.
✓
Match the inventory list to your home
Walk every room and compare. Items listed that you are not moving, or items missing that you plan to ship, can change the price.
✓
Check for accessorial fees
Stairs, elevators, long carries, shuttle service, and packing should each appear with a rate or a note that they are not included.
✓
Find the payment terms
Accepted forms of payment, the amount due at delivery, and whether credit is available should all be spelled out.
✓
Look for the tariff reference
On a non-binding estimate, the mover should point you to the tariff provisions used to calculate the final bill.
✓
Note the survey method
Within 50 miles of the mover's office, federal rules require a physical survey unless you sign a written waiver in advance.
✓
Verify the revision clause
Confirm that any change in scope requires a new written estimate before loading, and that the original binding estimate is reaffirmed if no change is made.
When federal interstate rules may not apply
The 110% rule, the binding and non-binding definitions, the written survey requirement, and the impracticable operations cap are federal protections that apply to interstate household goods moves under FMCSA oversight. If your move starts and ends in the same state, federal interstate rules generally do not apply. Your state may have its own licensing, estimate, and arbitration rules, and those vary widely. Before signing an in-state estimate, check your state utility or transportation regulator's website for the rules that govern intrastate movers in your area.
Picking the estimate type that fits your move
01
Decide how settled your inventory is
If you have finished decluttering and know exactly what is going on the truck, a binding estimate gives you the strongest budget certainty. If you are still sorting, donating, or selling, the flexibility of non-binding or not-to-exceed is safer.
02
Match the estimate to your budget tolerance
A binding price is best when you need to know the total weeks before move day. A non-binding estimate is workable when you can set aside at least 110% of the estimate in cash or certified funds for delivery day.
03
Ask about not-to-exceed first
If your movers offer it, a binding not-to-exceed estimate combines price protection with the chance to pay less if you trim the load. It is often the best balance for long-distance moves.
04
Get changes in writing before loading
Any added item, new accessorial service, or scope change should be captured in a revised written estimate or addendum before the truck is packed. After loading, the mover's ability to amend the estimate is limited.
SUMMARY
The bottom line
Choose a binding estimate when your inventory is final and you need price certainty. Choose a non-binding estimate when your shipment is still in flux and you can cover 110% of the estimate on delivery day. Ask for a binding not-to-exceed estimate first if it is available — it caps your risk while letting you save by moving less. Whatever you choose, verify the type, inventory, accessorial fees, payment terms, and revision clause in writing before you sign, and remember that federal interstate protections may not cover an in-state move.
Common questions
Before you move on
Is a verbal quote from a mover legally enforceable?+
No. For an interstate move, the estimate must be in writing, signed by both parties, and provided to you at the time you sign. A verbal quote is not binding, even if the mover confirms a number over the phone.
Can a binding estimate change after I sign it?+
Only before the truck is loaded and only in writing. After loading, the original binding estimate is generally reaffirmed unless you and the mover agree in writing to treat it as non-binding. Added services and impracticable operations charges (capped at 15% of other charges due) can still be added at delivery.
What is the 110% rule?+
On an interstate non-binding estimate, the mover cannot require more than 110% of the estimate at delivery. The balance, if any, is billed later (typically within 30 days), giving you time to review the charges.
Does a not-to-exceed estimate cost extra?+
Movers may charge for providing a binding or not-to-exceed estimate, but a non-binding estimate must be provided free of charge on interstate moves. Ask each mover what they charge for an in-home survey and a written estimate.
What if my move is in-state — do these rules still apply?+
Generally no. Federal FMCSA protections cover interstate moves. For in-state moves, check your state utility or transportation regulator for the rules that govern intrastate household goods carriers in your area.
