Binding Estimate vs Non-Binding Estimate: What Each Means for Your Final Moving Bill

When a moving company gives you a price, that number can mean three very different things depending on the estimate type. A binding estimate locks your price. A non-binding estimate is a guess. A binding not-to-exceed estimate caps your price but can go lower.

Federal law (49 CFR Part 375) requires interstate movers to offer one of these estimate types before loading your belongings. The estimate type determines whether you can be charged more at delivery, how much more, and what recourse you have if the final bill surprises you.

Most consumers do not know which type of estimate they received until the bill arrives. That is the root of most moving disputes. Understanding the differences before you sign anything is the single most effective way to protect yourself from overcharges.

A binding estimate guarantees your total price. The mover cannot charge more than the quoted amount, even if the shipment weighs more than estimated or takes longer than expected. However, the mover also cannot charge less. If your shipment turns out to be lighter than estimated, you still pay the quoted price. Binding estimates are most common for long-distance moves where the mover conducts an in-home or virtual survey.

A non-binding estimate is the mover's best guess based on the information available. The final price is determined by actual weight and services. Federal regulations limit the amount a mover can collect at delivery to 110% of the non-binding estimate. Any charges above 110% must be billed within 30 days and you have 30 days to pay. Non-binding estimates are standard for local moves and for movers who estimate remotely without seeing your belongings.

A binding not-to-exceed estimate is the consumer-friendliest option. It sets a maximum price (like a binding estimate) but allows the final bill to be lower if your shipment weighs less than estimated. You get the upside protection of a binding estimate with the potential savings of a non-binding estimate.

With a binding estimate, the mover absorbs the extra cost. If they quoted $4,000 and the move actually costs $5,200 in labor and fuel, you still pay $4,000. This is why movers tend to pad binding estimates slightly. They build in a margin to protect themselves from underestimating.

With a non-binding estimate, you are responsible for the actual cost. If the estimate was $3,000 but the actual weight-based cost is $4,500, you owe $4,500. At delivery, the mover can collect up to $3,300 (110% of the estimate). The remaining $1,200 is billed later. You must pay the 110% amount to receive your belongings.

With a binding not-to-exceed estimate, you pay the quoted amount or the actual cost, whichever is lower. If the estimate was $4,000 and the actual cost was $3,400, you pay $3,400. If the actual cost was $4,800, you pay $4,000.

Choose a binding estimate when you need absolute cost certainty. This is especially important for corporate relocations with fixed budgets, when financing a move with a personal loan, or when the mover has not physically seen your belongings. The tradeoff is a slightly higher quoted price.

A non-binding estimate works well when you are confident in the inventory, when the mover has done a thorough in-home survey, or when you are comfortable with some price variability. It can result in a lower final bill if you own fewer heavy items than average.

A binding not-to-exceed estimate is the best option for consumers in nearly every scenario. It eliminates upside risk while preserving downside savings. Not all movers offer it, and those that do may quote 5% to 10% higher than a non-binding estimate. That premium is almost always worth paying.

A mover who refuses to put the estimate type in writing is a mover to avoid. Federal law requires the estimate to be written and to clearly state whether it is binding or non-binding.

Watch for movers who give a low non-binding estimate over the phone without seeing your belongings, then present a much higher bill at delivery. This is the most common moving scam in the FMCSA complaint database. In 2025, approximately 38% of consumer complaints to FMCSA involved final bills that exceeded the estimate by more than 25%.

Always request the estimate in writing before signing any contract. Compare at least three estimates of the same type to ensure you are evaluating apples to apples. If one mover quotes $2,500 non-binding and another quotes $3,800 binding, those numbers are not directly comparable.
