Binding vs. Non-Binding Moving Estimates: What's the Difference?
Reviewed by Joey Padgett · Last reviewed September 2026
The type of estimate you sign determines what a mover can legally charge you when your belongings arrive. This is one of the most important things to understand before you book, and one of the most frequently misunderstood by consumers.
The Three Types of Moving Estimates
Non-Binding Estimate
The most common type and the least protective for consumers.
A non-binding estimate is based on the mover's assessment of what your shipment will weigh and what services you'll need. It is not a price guarantee. The final bill is determined by the actual weight of your shipment and the actual services performed.
Under federal regulations (for interstate moves), a mover cannot require you to pay more than 110% of the non-binding estimate at the time of delivery. The remaining amount, if any, is due within 30 days.
What this means in practice: If your non-binding estimate was $3,000, the mover can demand no more than $3,300 at delivery. If your actual costs come to $4,000, you pay $3,300 on delivery and the remaining $700 within 30 days.
The 110% rule offers some protection. But a non-binding estimate that was based on an incomplete inventory can still result in a significantly higher bill than expected.
Binding Estimate
A price guarantee. The mover agrees to perform the move for the stated price regardless of the actual weight. You are also bound to that price: if your shipment is lighter than expected, you still pay the agreed amount.
A binding estimate requires a thorough inventory. The mover is taking on the risk of underestimating your load, so they need to know what they're committing to.
For the consumer, a binding estimate eliminates the uncertainty of weight-based pricing. What you agreed to in the estimate is what you pay at delivery for the services and items listed.
Important exceptions: If you add items after the binding estimate is signed, the mover can charge for the additions. Additional charges can also apply for services you request that weren't in the original estimate, or if impracticable operations arise — situations that couldn't reasonably have been anticipated at the time of the estimate. The binding estimate covers what was included in the original inventory under standard conditions.
Binding Not-to-Exceed Estimate
Also called a "guaranteed not-to-exceed" estimate, this is the most consumer-friendly option when available.
It works like a binding estimate with one key difference: if your actual shipment weighs less than estimated, you pay the lower amount. The price can go down but not up.
Not all companies offer this. It's worth asking for specifically.
Which Type Should You Get?
For predictability and peace of mind: Binding or binding not-to-exceed.
For long-distance moves where you have a complete, accurate inventory: Binding estimates work well because the price is clear from the start.
If you're concerned about your own inventory changing before the move: A binding estimate based on what you had when it was created may need to be revised if your inventory changes significantly.
If a mover only offers non-binding estimates: That's not automatically a red flag. Non-binding estimates with a thorough inventory and a reputable company are common and work fine. The risk is primarily when the inventory was incomplete or the mover was careless with the estimate.
What Federal Law Says
For interstate moves, the FMCSA's regulations cover several consumer protections related to estimates:
For non-binding estimates: The mover must provide a written estimate. At delivery, they cannot require payment of more than 110% of the estimate before releasing your goods. Any amount over the estimate is due within 30 days of delivery.
For binding estimates: The mover is bound to the stated price for the goods and services listed. They cannot demand more for items already in the estimate. Charges for shipper-requested additions or impracticable operations are handled separately.
For all estimates: The estimate must be in writing. Verbal-only estimates are not enforceable in the same way. If a company provides only a verbal quote, ask for the written estimate before signing anything.
The mover is required to give you a copy of your estimate and the bill of lading (the contract) before moving day. Read them. Make sure the numbers match what you discussed.
Common Estimate-Related Disputes
"Your items weighed more than estimated."
For non-binding estimates, this is the most common basis for a higher final bill. You have the right to request a reweigh before delivery. Under FMCSA rules, the mover must honor a reweigh request.
"We had to perform additional services."
Stairs, long carries, elevator access, and similar fees should be disclosed in the estimate. A mover who adds these at delivery without prior written notice is on uncertain legal ground.
"You added items."
If you added items after a binding estimate was signed, the mover can charge for the additions. What they cannot do is charge for items that were included in the original inventory.
The estimate was never put in writing.
Without a written estimate, enforcing any specific price is difficult. Never agree to a move without a written estimate.
Before You Sign
Any written estimate you receive should include:
- Company name, address, and USDOT/MC number
- Clear statement of whether it is binding, non-binding, or not-to-exceed
- Estimated weight or volume
- Itemized list of all services included
- Itemized list of all fees (fuel surcharge, stair fees, long carry, specialty items)
- Delivery window for long-distance moves
If the estimate is vague on any of these, ask for specifics in writing before signing.
