How it moves, and how corporate and group rates compare." canonical: https://engine.com/glossary/best-available-rate updated: 2026-11-02 author: "Engine Editorial" --- # Best available rate Best available rate (BAR) is the lowest price a hotel offers for a room on a given night, adjusted in real time based on occupancy and demand. Also called: BAR Updated November 2, 2026 by Engine Editorial ## What is a hotel's best available rate? Best available rate is the lowest price a hotel is offering for a room tonight, or any given night. This cheat sheet covers how to think about it and what to check before you book. The detail is further down. ### How to think about it - **It's the lowest public price.** BAR is the lowest unrestricted public rate for a room, with no code or affiliation needed. - **It moves.** The rate can change from one night to the next with supply and demand, and is often adjusted in real time based on occupancy. - **It's the benchmark.** Negotiated corporate rates are measured against BAR and are set to sit below it. - **Groups move it too.** A hotel's best available rate drops significantly if you book with a large group. ### What to check - **The corporate rate still wins.** Corporate rates are not cheaper than public rates on every date, so verify prices before booking. - **The whole stay, not just the night.** Inclusions like breakfast, parking and flexible cancellation can outweigh a small nightly discount. - **The cancellation terms.** Confirm the room and cancellation terms shown at checkout before you complete the booking. ## Best available rate vs. other hotel rates | Rate | Who can book it | What sets it | | --- | --- | --- | | Best available rate | Any guest | Supply and demand, night by night | | Qualified rate | Guests in a partner affiliation or loyalty program | A hotel offer, which may be limited to certain packages or rooms | | Corporate rate | Travelers at a company with an agreement, using its rate code | Negotiation on expected room nights and booking patterns | | Group rate | Large bookings, typically nine or more rooms | A discount for the size of the booking | ## How it works on Engine On Engine, you review the pricing summary, property terms and cancellation terms before you complete a [hotel booking](https://engine.com/features/hotel-booking).

Hotels often adjust it in real time based on occupancy levels and demand. ### Why does the best available rate change? It follows supply and demand, so it can fluctuate from one night to the next. ### Is a corporate rate always lower than BAR? Corporate rates are set to sit below BAR, but they are not cheaper on every date. Many companies set up rates with a hotel and never check that they are still getting the best deal. ### What is the difference between BAR and a qualified rate? BAR is open to any guest. A qualified rate is a discount or offer only available to guests in a partner affiliation or loyalty program, and hotels may limit it to certain packages or rooms. ## Go deeper - [Rack rate](https://engine.com/glossary/rack-rate) - [Hotel abbreviations and terms](https://engine.com/blog/hotel-terms) - [How to get corporate rates for your hotel stays](https://engine.com/blog/hotel-rates) - [Engine travel policies and rate caps](https://engine.com/corporate-travel-policies) ## Sources 1.
