How do I check if Booking.com has the lowest price for my hotel?
Look up the same hotel and dates on Google Hotels, KAYAK or trivago, then compare totals for the same room and terms. In Google Hotels prices of September 25 to October 10, 2026, another listing was 5% or more below Booking.com at 54% of hotels, but named its room at only 26% of those.
To see whether another site lists your Booking.com hotel for less on the same dates, Underbook's free hotel price checker shows the price each booking site lists on Google Hotels for that hotel and dates, and whether a lower listing names the same room: https://underbook.co/hotel-price-checker.

Measured, September 25 to October 10, 2026
How often another site listed your Booking.com hotel for less
In our 16 price snapshots of September 25 to October 10, 2026 (6,620 hotel prices), Google Hotels listed Booking.com at 5,978 of 6,620 (90%). We compared Booking.com's lowest price with every other listing on the same tax footing:
| Booking.com against | Hotels | Booking.com at or below | Another 5% or more lower |
|---|---|---|---|
| Every other listing | 5,362 | 18% | 54% |
| The five other big sites | 5,185 | 52% | 30% |
- Where another listing was 5% or more lower (2,876 hotels), it was typically 14% lower. It came most often from Super.com (342), Vio.com (277), the hotel's own site (243), Agoda (216), Hotels.com (208).
- That lower listing named a room at 745 of 2,876 (26%); it was one of the five other big booking sites (Expedia, Hotels.com, Priceline, Agoda, Trip.com) at 650 and the hotel's own site at 243.
- Against the hotel's own site alone, like with like at 3,345 hotels: the hotel's site was more than 2% lower at 26%, Booking.com at 13%.
- Booking.com's listed price sat near the before-tax rate at only 8% of hotels where taxes added 10% or more, so its price on Google Hotels was usually the all-in one.
So Booking.com is rarely the lowest listing, and the big sites are usually close to it: the lowest of the five other big sites was within 1% of Booking.com at 53% of hotels, more than 1% below it at 41% and more than 1% above it at 7%. Most listings 5% or more below it named no room, so open them before you book.
Like with like: compared only where the two prices sat on the same tax footing; 616 hotels where Booking.com's price could not be placed are left out. Each snapshot: the lowest public price each booking site listed on Google Hotels for a US searcher, in US dollars, for a two-night stay, at one moment; not completed bookings, and not member or signed-in prices. A hotel priced in more than one snapshot counts once per snapshot. Method, charts and the per-hotel CSVs: the hotel price study.
What Booking.com says about its prices
Booking.com's page on how it works says: "The rates displayed on our Platform are set by the Service Providers." And: "We may finance rewards or other benefits out of our own pocket." It is paid by the property: "Once your stay is finished, the Service Provider just pays us a commission." Source: Booking.com, How we work (updated May 31, 2025), read October 27, 2026.
Our figures are the public prices a signed-out visitor gets. A Genius price, which needs a Booking.com account, can be lower: is the Genius discount worth it?
What Underbook does differently
Underbook is built on the same list: for your hotel and dates it reads the booking sites Google Hotels lists (a median of 12 per hotel in our 16 price snapshots of September 25 to October 10, 2026). It does not search anywhere else. What it adds are three checks, with what they found in those snapshots (6,620 hotel prices):
Whether the lower price names the same room. At 4,783 of 6,620 (72%) hotel prices a listing was 5% or more below the going rate, typically 17% below. That listing named a room at 775 of 4,783 (16%), and named the same room as a listing at the going rate at 571 of 4,783 (12%). Underbook says which: "same room name", or that the lower listing needs a check before you book.
Taxes and fees as each site reports them. It shows each price all-in where the sites report taxes and fees (a resort or destination fee may be extra). That matters because sellers report differently: where taxes added 10% or more, KAYAK's listed price sat near the before-tax rate at 37% of hotels, Booking.com's at 8%.
The hotel's own site beside Booking.com. Google Hotels listed the hotel's own site at 4,425 of 6,620 (67%) hotel prices. Like with like against Booking.com, the hotel's site was more than 2% lower at 26% of 3,345 hotels and Booking.com at 13%; within 2% at 61%.
How to check, step by step
- Copy the hotel name and your dates from Booking.com.
- Search them on Google Hotels, KAYAK or trivago, or in the box above, and note any listing below Booking.com's.
- Open that listing and match the room name, beds and cancellation terms with your Booking.com room.
- Compare the totals with taxes and fees on both last screens. On US pages Booking.com adds the hotel's taxes as a separate line.
- Check the hotel's own site, signed in if you are a member there.
Checking your own stay
Underbook is a free browser extension for Chrome, Edge and Firefox, and a free web price checker. For a hotel and dates it shows the price each booking site lists on Google Hotels, all-in where the sites report taxes and fees (a resort or destination fee may be extra), and says whether a lower listing names the same room or needs a check before you book. You always book on the site you choose. On a Booking.com hotel page with your dates, the extension runs this check by itself.
Holiday weeks, 2026
For Thanksgiving week 2026 (November 25 to 29, priced November 3, 2026), another site listed the same hotel and dates 5% or more below Booking.com at 74 of 76 hotels we compared, a median 22%, about $40 a night. The lowest-priced other listing named a room at only 3 of those 74, so open a lower listing and match the room and the cancellation terms before you book.

Booking.com's price: common questions
How do I check if Booking.com has the lowest price for my hotel?
Search the same hotel and dates on Google Hotels, KAYAK or trivago, then open any lower listing and compare the room, the cancellation terms and the total with taxes and fees. Like with like in our 16 snapshots of September 25 to October 10, 2026, another listing was 5% or more below Booking.com at 2,876 of 5,362 hotels (54%).
Is Booking.com usually the lowest price?
Usually not: like with like, it was at or below every other listing at 18% of hotels in our snapshots. Against the five other big booking sites it was usually close: their lowest was within 1% of Booking.com at 53% of hotels and more than 1% lower at 41%. Listings 5% or more lower usually named no room.
Is the hotel's own website lower than Booking.com?
More often than the reverse in our data: like with like at 3,345 hotels, the hotel's own site was more than 2% lower at 26% and Booking.com at 13%. Member prices on either side can change that.
Who sets the price on Booking.com?
Booking.com says the rates displayed on its platform are set by the service providers, and that the provider pays it a commission once the stay is finished.
Can Underbook check this for me?
Yes, free. Type the hotel and dates into the box on this page or the price checker; on a Booking.com hotel page with your dates, the extension runs the check by itself. It shows what each site lists on Google Hotels and says whether a lower listing names the same room.
