Refundable or non-refundable?
It depends on the premium, and on whether anyone watches the price.
A refundable rate costs a little more because it keeps a door open: you can cancel, change plans, or rebook if the price falls. A non-refundable rate is cheaper and final. We priced 5,830 hotels on every booking site Google Hotels lists to see what the door actually costs, and worked out how far a price has to fall before using it comes out ahead.

From our 14 snapshots of 5,830 hotels in 348 cities (September 25 to October 1, 2026), each for a two-night stay 35 days out, 2 adults, US market, USD. Full method and per-site figures: is free cancellation worth it?
When a refundable booking and a rebook come out ahead
Say the cheapest non-refundable rate is $200 a night and free cancellation costs 9% more, $218. You book the refundable one. Later the price falls and you rebook. You only end up below the $200 you passed up if the rate you rebook at is under $200: a fall of more than $18, or about 8.3% of $218.
The rule: if free cancellation costs p more, the rate has to fall by more than p ÷ (1 + p) before the rebook beats the non-refundable price. In our data:
A quarter of hotels: premium 0.3% or less
Almost any drop puts you ahead
Premium 5%
The rate has to fall about 4.8%
The median premium, 9%
The rate has to fall about 8.3%
A quarter of hotels: premium 21.2% or more
The rate has to fall about 17.5% or more
So the cheaper the flexibility, the easier it is to come out ahead, and the price of flexibility varies a lot: at 1,535 of the 3,975 hotels with both kinds of listing (39%), the difference was 5% or less. Nobody can tell you in advance whether a price will fall. What you can control is how much you pay for the option, and whether anyone is watching when it does.
The premium buys more than a price bet
- Your plans can change. A refundable rate is insurance against a cancelled meeting, a sick child or a missed flight, whatever the price does.
- You can check the room. A cheap listing often does not say which room it is. With free cancellation you can book, read the room on the confirmation, and cancel if it is wrong.
- It can cost nothing. At 32% of hotels in our data, a big site's lowest rate was non-refundable while another site listed free cancellation for the same price or less. Look before you pay extra for flexibility on the site you are on.
When non-refundable is the better deal
When your dates are fixed, the premium is large, and you won't look at the price again. A refundable rate only turns into a lower price if you notice the drop before your free cancellation ends. If nobody checks, you paid for an option you never used.
Already on a non-refundable rate and the price fell? Rebooking won't get your money back, but there are a few things to try: what still works on a non-refundable booking.
"Free cancellation" in our figures is the label Google Hotels shows for a site's listed rate; "non-refundable" means a listing without that label. Most of those are non-refundable, but some may allow a partial refund or show their terms only on the site. Read the terms on the site itself before you book.
After you book, one number matters: what you paid
Once the refundable booking is made, the non-refundable price you skipped is history. The question becomes whether you can book the same stay for less than you paid, before your deadline. When you can, the steps are in how to rebook a hotel for a lower price.
Make the refundable rate earn its premium
The option is only worth something if someone checks the price before your free cancellation ends. We can do that part.
- You tell us what you paid per night, with taxes and fees, and the last day you can cancel for free.
- We check the rates listed for your hotel and dates once a day.
- We email you once if a listed rate is at least 5% lower than what you paid (and at least $5 a night lower, or about that in your currency) on two daily checks in a row. The email names the site and the price.
- You check the room before you rebook. A lower rate can be for another room, bed type or meal plan. You book and cancel yourself; we never do either.
- We stop at your free-cancellation date. We need two checks in a row, so a rate that first drops on your deadline day itself comes too late for an alert.
Free, no account. We never ask for your booking number, your name or your payment details.
Refundable vs non-refundable: common questions
How much more does a refundable hotel rate cost?
In our 14 snapshots of 5,830 hotels (September 25 to October 1, 2026), at the 3,975 hotels that had both kinds of listing, the cheapest listing with free cancellation cost a median 9% more than the cheapest non-refundable one. At 1,535 of them (39%) the difference was 5% or less.
When does booking refundable and rebooking come out ahead?
When the rate you rebook at is lower than the non-refundable price you passed up. If free cancellation cost p more, the rate has to fall by more than p divided by (1 + p): about 4.8% for a 5% premium, and about 8.3% for the 9% median premium in our data. Flexibility has value of its own if your plans might change.
Is a non-refundable hotel rate ever the better choice?
Yes, when your dates are fixed, the premium for free cancellation is large, and you will not check the price again. A non-refundable rate cannot be cancelled for a refund, so a later drop does not help you, and Underbook's booking watch only works for stays you can cancel for free.
Can I get free cancellation without paying more?
Often, on another site. At 1,869 of 5,830 hotels (32%), the lowest listed rate on at least one of Booking.com, Expedia, Hotels.com or Agoda had no free cancellation while another site listed free cancellation for the same price or less (within 2%).
