What Are Best Available Rates (BAR) and Why Are They Important?

The best available rate (BAR) is the lowest rate a hotel or car provider offers to the general public for a specific room or vehicle at a specific time.

BAR is usually a flexible rate, meaning you can often change or cancel it with fewer penalties than prepaid or promotional rates. Hotels and rental car companies use BAR as their main reference price and then build discounts and promotional offers on top of it.

This matters because many corporate and negotiated discounts are written as “X% off BAR.” If you do not understand what BAR is, you cannot tell whether your deals are actually good or how your prices compare to what the public gets. In business travel, BAR is a core concept for negotiating, benchmarking, and enforcing travel policy.

Understanding the Core Functions of Best Available Rates (BAR)

How Does the Application of BARs Work?

Hotels and car rental companies use dynamic pricing, which means rates change based on:

Date and season
Market demand
Local events
Property or fleet inventory

At any given moment, the provider sets a BAR for each room type or car category. It is:

Publicly available (anyone can book it)
Usually flexible or semi-flexible
The baseline for many discounts and packages

Other rates, like corporate negotiated rates, loyalty discounts, or promotional offers, are usually expressed as a percentage off BAR.

BAR vs. Other Rate Types: An Overview

Platforms like Navan present these options side-by-side so travelers can weigh the immediate cost savings against the potential risk of a change in plans.

Rate Type	Comparison to BAR	Flexibility & Rules	Best For...
Best Available Rate (BAR)	The baseline or "anchor" price	Highest: Fully flexible; usually pay-at-hotel with 24-48h cancellation	Travelers needing maximum flexibility or booking last-minute
Promotional / Sale Rate	Usually lower than BAR	Low: Often non-refundable and requires full prepayment	Travelers certain of their dates looking for a deal
Advance Purchase Rate	Discounted (often 10-20% off BAR)	Strict: Must be booked 14-30+ days out; non-changeable	Planners who want to lock in a low price early
Corporate Negotiated Rate	Fixed % off or a fixed ceiling vs. BAR	High: Often matches BAR flexibility; includes corporate perks	Employees booking for business with specific company benefits
Package Rate	Higher total cost (BAR + value of extras)	Varies: Depends on the specific hotel's policy for that bundle	Travelers who want "all-in" value (breakfast, parking, etc.)

How It Looks in Policy

When using a travel management platform like Navan, you will often see these rates compared to the "lowest logical rate." For example:

The BAR might be the benchmark for a policy-compliant stay.
A corporate rate might be flagged as the "preferred" option because it offers the same flexibility as BAR but at a lower negotiated cost.

Why Best Available Rates (BAR) Matter

Companies that understand and manage BAR effectively can secure better deals and make smarter booking decisions.

Here is why BARs matter:

Negotiation and Savings

Most corporate hotel and car rental contracts are based on a percentage off BAR. If you know how BAR behaves in your key cities, you can negotiate more realistic and valuable discounts.

Policy Design and Enforcement

Travel policies often state, “Book the corporate negotiated rate or BAR, whichever is lower.” If your tools cannot compare both, you risk overpaying.

Benchmarking and Compliance

Finance and procurement teams use BAR to check if travelers are booking the lowest reasonable rate in-policy. Comparing what was booked to the same-day BAR helps spot savings opportunities.

Traveler Flexibility

Since BAR is often more flexible than prepaid deals, it is critical for trips that might change. A slightly higher BAR rate may save money overall by avoiding change and cancellation penalties.

Practical Scenarios: The Best Available Rate in Corporate Travel

Scenario 1: Corporate Negotiated Rate vs. BAR

A corporate deal offers 15% off the BAR at a hotel in Chicago.
On a certain night, the BAR is $200, making the corporate rate $170. A promotional prepaid rate is $160 but is nonrefundable.
Result: For a trip that might change, the $170 corporate rate provides flexibility for only $10 more than the nonrefundable promo and is clearly better than paying the full BAR.

Scenario 2: BAR Beats the Corporate Rate

A corporate deal has a fixed rate of $180 per night.
During the off-season, the hotel’s BAR drops to $150 to attract leisure guests.
Result: Booking platforms like Navan can enforce a “use BAR when cheaper than negotiated” policy, ensuring you book the $150 rate instead of the higher $180 corporate rate.

Scenario 3: Last-Minute Trip During a Big Event

A citywide conference raises demand, and the BAR jumps to $400.
Your corporate rate has a ceiling of $280.
Result: If contract terms allow, the system should still return your $280 rate and flag it as a corporate rate that beats BAR. This is where strong agreements and good technology deliver real savings.

Common Challenges and Solutions When Applying the Best Available Rate

Challenge 1: Confusing BAR with the absolute cheapest rate.
BAR is the lowest public flexible rate, not always the absolute lowest price. Solution: Educate stakeholders that BAR is the “best flexible public rate,” not every possible deal. Use booking tools that label rate types clearly.

Challenge 2: Not seeing when BAR is cheaper than corporate rates.
If your tools are not comparing BAR and corporate rates simultaneously, travelers may book a higher corporate rate out of habit. Solution: Use integrated platforms like Navan that automatically show the lowest in-policy rate, whether it is BAR or negotiated, by evaluating multiple rate sources in real time.

Challenge 3: Inconsistent BAR across channels.
Sometimes the BAR on a hotel’s own site looks different from what a GDS or OTA shows. Solution: Monitor key properties regularly. If you see repeated mismatches, address them in negotiations and consider rate parity clauses in your contracts.

Challenge 4: It is hard to measure savings against BAR.
Without clean data, you cannot see if your travelers are truly getting rates at or below BAR. Solution: Capture the rate type and BAR at the time of booking. Modern T&E platforms like Navan centralize this data for easy reporting on savings.

Challenge 5: Traveler confusion about flexibility.
Travelers may assume “best available rate” always means flexible and then pick the cheapest option without checking the conditions. Solution: Make sure your booking experience clearly shows whether a rate is BAR, promo, or prepaid, along with its change and cancellation rules.

Key Takeaway

While BAR serves as the benchmark for hotel pricing, corporate rates offer stability and specific perks for business travelers, whereas promotional rates trade flexibility for the deepest possible discounts.

Dynamic pricing: A pricing strategy where rates change based on demand, time, and availability. BAR is a dynamic rate that reflects current conditions.
Corporate negotiated rate: A special rate your company agrees to with a hotel or rental car provider, often tied to BAR.
Rate parity: An agreement that a hotel will offer the same BAR across all public channels.
Rack rate: Historically, the full “list price” for a hotel room, often higher than BAR. Today, BAR is the main reference.
