Every moving article on the internet says the same thing: "Get a binding estimate! It's the only way to protect yourself!"
It's well-meaning advice. It's also mostly wrong. If you hire a bad moving company, it doesn't matter what's written on the estimate. Binding, non-binding, cross-stitched onto a pillow, none of it saves you when things go sideways.
Quick Definitions (So You Can Skip the Other Articles)
- Binding estimate:the price is "locked in" based on the inventory you gave. You pay that price regardless of actual weight.
- Non-binding estimate: an educated guess based on estimated weight. Final price is based on actual weight and services delivered, usually capped at 110% of the estimate at delivery.
On paper, binding sounds like better protection. In practice, both can be revised.
What Does Federal Law Actually Say?
Both estimate types live inside the same federal framework. For interstate moves, the Federal Motor Carrier Safety Administration regulates household goods carriers under 49 CFR Part 375. The two relevant clauses for estimates:
- 375.401 requires every mover to give you a written estimate based on either a physical inventory or a written description of the shipment. Phone-only estimates are not compliant.
- 375.501-505 covers the non-binding 110% rule. If the actual charges exceed the non-binding estimate, the mover can collect no more than 110% of the estimate at delivery. The remaining balance can be billed but you have 30 days to pay it without losing your shipment.
Local moves (origin and destination in the same state) are not covered by 49 CFR. They are regulated by state moving boards. Maryland, Virginia, D.C., and West Virginia each have their own rules; none of them mandate the 110% cap that federal interstate moves use.
Here's What the Articles Don't Tell You
Binding estimates get revised all the time. The contract usually reads something like "binding based on the inventory provided." If the mover arrives and decides the inventory is off, more boxes, heavier items, a couch you forgot to mention, they can write up a revised estimate on the spot. You sign it or you don't get moved.
Non-binding estimates work the same way, with a different wrapper. The mover shows up, sees more than they expected, and adjusts. The 110% cap only protects you if the inventory stays the same. The second it changes, so does the cap.
A Worked Example: Same Move, Both Estimate Types
Say you book a 2-bedroom apartment move from Bethesda to Northern Virginia. The walkthrough inventory comes in around 4,200 pounds. Two movers quote you:
- Mover A: binding flat-rate quote of $2,400. You sign. Move day, the crew arrives. They see your guest-room dresser was not on the walkthrough video, plus 6 extra boxes you packed last week. They draft a new binding estimate at $2,950. You sign because you have nowhere else to go that day. Net cost: $2,950.
- Mover B: non-binding estimate of $2,400 at $135/hour with a 4-hour minimum. Same situation: extra dresser, extra boxes. Actual weight comes in at 4,800 lbs and the job runs about 30 minutes longer than estimated. Final charge: ~$2,700, capped by the 110% rule at $2,640 if you used the non-binding interstate version of this. Net cost: $2,640 to $2,700.
Same scope creep, same crew, different paperwork, different outcome. The binding estimate looked safer on paper and delivered the higher final bill. The non-binding estimate looked riskier on paper and the regulatory cap actually held.
Now flip the scenario. With a dishonest non-binding mover, the same crew might pad the time by an extra hour and a half, claim heavier inventory than reality, and present a $3,800 invoice. With a dishonest binding mover, the revised on-site estimate could be $4,200 because they know you cannot say no with the truck half loaded. The dishonest version is worse regardless of paperwork.
What Actually Matters in a Moving Estimate?
The only thing protecting you on move day is the company you hired. A trustworthy mover will honor a non-binding estimate without games. A dishonest mover will find ways around a binding estimate. The paperwork is downstream of the decision.
What Red Flags Outrank the Estimate Type?
- "Cash only" or a massive cash deposit requested upfront. Legitimate movers take cards.
- No physical address. Nothing but a phone number and a website? Walk away.
- They won't do an in-home or virtual survey. Phone-only quote is the number one predictor of a hostage situation.
- Price is dramatically below everyone else.Either they're losing money on purpose (unsustainable, so what happens on your move?) or the number isn't the real number.
- No reviews, or nothing but 5-star reviews with identical phrasing. Pattern matters more than average.
- The salesperson dodges questions about licensing, crews, or valuation. A clear answer is table stakes.
So, Which One Should You Ask For?
If you've done the work above and you're confident in the company, it genuinely doesn't matter much. Pick whichever type they default to. For most local moves in the DMV, that's non-binding hourly or flat-rate based on the walkthrough. For out of the state moves, binding is common because it simplifies the billing.
The estimate type is a footnote. Your research on the company is the whole thing.
