Binding vs. Non-Binding Moving Estimates
For interstate moves, a binding estimate guarantees the price for the listed items, while a non-binding estimate is a best guess, and the mover can't require more than 110% of it at delivery. For moves within California, every move gets a written estimate after inspection and a Not to Exceed price that caps the bill.

How do estimates work for moves within California?
Under Item 108 of the 2026 Maximum Rate Tariff, an estimate may be given only after a visual inspection, and it must be in writing. If it's issued at least three days before the move, the most you can be charged is the lesser of the estimate plus Change Orders, or the actual charges at the agreed rates. If it's issued later, it can't exceed maximum-rate charges.
The Agreement for Moving Services must state a Not to Exceed price. Change Orders for added items or services must be signed before the extra work begins.
What is a binding estimate for an interstate move?
FMCSA defines it as a written agreement made in advance that guarantees the total cost of the move for the quantities and services shown. If you add items or services, the mover can revise it.
What is a non-binding estimate, and what's the 110% rule?
A non-binding estimate is the mover's approximation of cost; FMCSA suggests expecting about 10% more. At delivery, if the charges exceed 110% of the estimate, the mover must release your shipment once you pay 110% and give you at least 30 days to pay the rest. Charges for impracticable operations are capped at 15% of the other charges due at delivery.
Frequently asked questions
Can a California mover charge more than the Not to Exceed price?
Only for added items or services covered by a signed Change Order.
What is the 110% rule?
On an interstate non-binding estimate, you can get your goods by paying 110% of the estimate; the mover must defer the rest for at least 30 days.
Can I get a binding estimate over the phone?
For a California move, no: estimates must follow a visual inspection. FMCSA also lists phone-only quotes as a red flag.
