A binding estimate is a written contract that caps the price of your interstate move at the quoted amount — no matter how much your shipment actually weighs when it hits the scale. Under FMCSA regulations, a licensed interstate mover must honor a binding estimate as long as you don't add items or services after the estimate is issued. If you're moving across state lines, a binding estimate is the single most effective tool you have for controlling your final bill.
What is a binding estimate — and how is it different from a non-binding one?
A binding estimate is a fixed-price quote. The mover is legally committed to that price for the items and services listed. If the truck weighs more than expected, that's the mover's problem, not yours.
A non-binding estimate is an educated guess. The mover gives you a projected cost, but your final charge is based on actual weight. Under FMCSA rules (49 CFR §375.603), a mover can collect up to 110% of a non-binding estimate at delivery — and bill you for the rest within 30 days. That 10% buffer sounds small, but on a $6,000 move it adds $600 you weren't expecting at the door.
| Estimate Type | Price Basis | Max Charged at Delivery | Risk to You |
|---|---|---|---|
| Binding | Quoted price, fixed | Exactly what was quoted | Low — if inventory is accurate |
| Non-binding | Actual shipment weight | Up to 110% of estimate | Medium-high — weight can surprise |
| Binding not-to-exceed | Actual weight or quote, whichever is lower | Quote amount or less | Lowest — but less common |
We've seen customers lose $800–$1,500 on non-binding estimates when they didn't realize how much their garage gear weighed. For most families, binding is worth the modest premium movers sometimes charge for it.
When can a mover legally charge more than a binding estimate?
There are two situations where a binding estimate can be exceeded — both are legitimate, and knowing them protects you:
-
You added items after the estimate was issued. If the mover's crew shows up and there's a treadmill, a second refrigerator, or a full attic's worth of boxes that weren't on the original inventory, the mover can issue a revised estimate or charge for the extras.
-
You requested additional services on moving day. If you ask the crew to disassemble furniture they weren't told about, carry items up extra flights of stairs not disclosed, or add packing services, those are billable additions.
The key protection: if the mover adds charges for services they failed to note during the survey — a long carry, an elevator, a flight of stairs they could clearly see — you have grounds to dispute. Document everything before signing.
How to get a binding estimate that actually protects you
Step 1: Demand an in-home or virtual survey — not just a phone call
A binding estimate is only as accurate as the inventory behind it. A mover who quotes you over the phone without seeing your items is guessing, and that guess often comes back as a revised estimate after loading. Reputable long-distance movers will do a video walkthrough or send a sales rep to your home. This is standard practice — and it's free.
Step 2: Walk every room, including the garage, attic, and basement
We've packed thousands of homes. The garage is where estimates go wrong. Walk the estimator through every space, including the awkward half-filled storage closet and the shed out back. Point out heavy items: gun safes, exercise equipment, riding mowers. If it's in the house, it should be on the inventory sheet.
Step 3: Read the inventory sheet before you sign anything
The binding estimate is only binding for the items listed. Get a copy of the written inventory and compare it to your actual belongings. If a piece of furniture is missing from the list, add it. If a room isn't listed, ask why. Our post on binding estimates for long-distance moves walks through every line of a typical estimate in detail.
Step 4: Confirm the estimate includes all services — not just the base haul
Ask the mover to spell out:
- Fuel surcharges (required to be disclosed under FMCSA rules)
- Stair or elevator carry fees
- Long-carry charges (typically triggered when the truck can't park within 75 feet of your door)
- Shuttle fees (if a smaller truck is needed for delivery access)
- Packing materials, if you're using full-service packing
These are the line items that inflate moving bills without warning. Get them in writing before the truck is loaded.
Step 5: Verify the mover's USDOT number and operating authority
A binding estimate from an unlicensed mover is worth nothing. Every interstate mover must have a USDOT number and active operating authority issued by the FMCSA. You can verify both free at the FMCSA's online lookup tool (protectyourmove.gov). If a mover can't produce these, walk away. Our guide on how movers are licensed and insured covers exactly what to check and how to check it.
What does a binding estimate typically cost on a long-distance move?
Long-distance moving prices vary widely based on shipment weight, distance, and time of year. Here are realistic 2026 ranges for common move sizes:
| Move Size | Approx. Weight | 500 Miles | 1,500 Miles | 2,500+ Miles |
|---|---|---|---|---|
| 1-bedroom / studio | 2,000–3,500 lbs | $1,800–$3,200 | $2,800–$4,800 | $3,800–$6,500 |
| 2-bedroom | 4,000–6,000 lbs | $2,800–$4,800 | $4,200–$7,000 | $5,500–$9,500 |
| 3-bedroom | 7,000–10,000 lbs | $4,500–$7,500 | $6,500–$10,500 | $8,500–$14,000 |
| 4-bedroom+ | 10,000–14,000 lbs | $6,500–$10,500 | $9,000–$15,000 | $12,000–$20,000+ |
Ranges reflect typical binding estimates from licensed interstate carriers in 2026. Peak season (May–August) and weekend bookings typically add 10–20% to base rates.

What happens at the weigh station — and can you request a reweigh?
For non-binding estimates, the carrier weighs the truck empty (tare weight) and then again full (gross weight). Your shipment weight is the difference. Under FMCSA rules, you have the right to request a reweigh before delivery, at no charge. If the reweigh comes in lower, you pay the lower amount. If it comes in higher, you pay the original weight. This is worth knowing even if you have a binding estimate — it tells you whether your inventory was accurate.
With a binding estimate, the weigh ticket is mostly irrelevant to your bill — but movers are still required to weigh the shipment and provide you with the weight ticket if asked.
Red flags that a "binding estimate" isn't really binding
After 35 years in this industry, these are the patterns we've seen that should make you pause:
- The estimate was given over the phone in under 10 minutes. No legitimate binding estimate for a multi-room move can be done without a real inventory.
- The contract uses language like "estimated binding" or "binding subject to reweigh." Real binding estimates don't have weight-based escape clauses.
- The mover asks for a large cash deposit — more than 20–25% upfront. This is a scam signal, not standard practice.
- The estimate is dramatically lower than every other quote you received. If one mover is 40% cheaper than three others, they're either planning to add charges later or they're not licensed. Here's how to spot those red flags in a quote before you sign anything.
Before you book: what to do with competing estimates
Get at least three written binding estimates for any long-distance move. Compare them line by line — not just the total. Look for differences in:
- The listed inventory (are all your items on each list?)
- Services included vs. charged separately
- Fuel surcharge structure
- Valuation coverage offered (released value vs. full value protection)
You can browse vetted long-distance movers on our directory, filtered by state and service type. If you're relocating to or from a specific region, searching by state helps you find carriers licensed for that corridor. And if you want to see what real customers say before you call, check verified mover reviews to compare reputations side by side.
Once you've narrowed it down, ask each mover to confirm the estimate in writing and make sure the word "binding" appears on the document itself — not just in the sales conversation.
Frequently asked questions
What is the difference between a binding estimate and a not-to-exceed estimate?
A binding estimate fixes your price at exactly the quoted amount. A not-to-exceed estimate (also called a "guaranteed not-to-exceed" or GNTE) sets a price ceiling — you pay the actual weight-based cost if it comes in lower, or the quoted amount if it comes in higher. A not-to-exceed estimate is generally the most customer-favorable option, but it's less commonly offered by standard interstate carriers.
Can a mover change a binding estimate after the truck is loaded?
No — once a binding estimate is issued and you've accepted it, the mover cannot raise the price for the inventory and services already listed. They can only charge more if you added items or requested new services after the original estimate was finalized. If a mover tries to demand more money at delivery without a legitimate reason, that is a federal violation and should be reported to the FMCSA.
Do I need a binding estimate for a local move?
Local moves (within a single state) are typically priced by the hour, so binding estimates are rare and usually unnecessary. Binding estimates are most important for interstate moves, where weight-based pricing creates the most uncertainty. For hourly local moves, the best protection is understanding how movers charge by the hour and getting a written estimate of the expected time range.
How far in advance should I get a binding estimate?
For a summer move (May–August), get estimates 6–8 weeks out. For fall or winter moves, 3–4 weeks is typically workable. Don't wait until two weeks before your move date — peak-season movers book up quickly, and a rushed estimate is more likely to miss items. If you're already cutting it close, our last-minute emergency moving guide covers what to do when time is short.
What valuation coverage does a binding estimate include?
Unless you upgrade, interstate movers are only required to include Released Value Protection — the federal minimum, which covers items at $0.60 per pound per article. That means a 10-pound laptop damaged in transit is worth $6 in compensation. Full Value Protection typically costs $100–$300 extra (depending on your shipment's declared value) and covers repair, replacement, or fair market value. Always ask what's included before signing.
What should I do if my mover holds my belongings and demands more money at delivery?
This is called a "hostage load" and it's a federal crime. Under FMCSA rules, a mover cannot hold your shipment pending payment of charges beyond what's on your binding estimate (plus any agreed-upon extras). If this happens, document everything, pay under protest if necessary to get your goods back, and file a complaint immediately with the FMCSA at 1-888-DOT-SAFT and your state attorney general's office.
