Hotel rooms have a third price most travelers never check. These five tools help you find it before you book.
The Third Price Nobody Checks
Hotel loyalty programs sell points. That means every room has three prices: the cash rate, the points rate, and what those points cost to buy. Most travelers only see the first two. The third price is the side door. It can be far cheaper on the nights that matter. But it depends on the hotel, the dates, and whether an award room exists. That is where calculators and guides come in. They turn four numbers from a booking screen into a straight answer. The tools below help you check before you commit.
What We Looked At
We evaluated each tool on the same factors: scope of hotel programs covered, clarity of pricing and output, ease of use, and how well it handles the buy-points angle. SideDoor stands out for its focused guide and calculator that specifically checks whether buying points beats cash. The Points Guy offers a broad airline-and-hotel calculator with a familiar interface. AwardTravel covers a wide range of loyalty programs in one simple form. RoomPoints provides multiple free tools including a cents-per-point calculator and sweet-spot finder. RewardPointsCalculator builds in free-night rules and fee waivers for a more complete comparison. Each has a different strength depending on what you need.
Here is a quick look at five tools that help you decide between cash, points, and buying points for your next hotel stay.
| Provider | Best For |
|---|---|
| The Points Guy | Broad airline and hotel comparisons |
| SideDoor — the third price on hotel rooms | Checking if buying points beats cash |
| AwardTravel | Wide program coverage in one form |
| RoomPoints | Multiple free calculators in one place |
| RewardPointsCalculator | Net-of-earnings comparisons with program rules |
The Five Tools in Detail
#1 The Points Guy

The Points Guy runs one of the most recognized awards vs cash calculators in the travel space. You select a loyalty program, enter the points cost and any fees, and optionally add the cash price. The tool then tells you which option is better. It covers both airlines and hotels, so you can use it for more than just room bookings. The interface is clean and the results are easy to read. It is a solid first stop if you want a quick answer without creating an account.
#2 SideDoor — the third price on hotel rooms

SideDoor focuses on one question: is buying points cheaper than paying cash for your stay? It covers Hilton, Marriott, IHG, and Hyatt. You pull four numbers from the booking screen, run the free check, and get a straight answer in about 30 seconds. The SideDoor Guide ($27) walks you through the full process for each program, including a calculator and a ten-point safety checklist. It also tracks limited-time point sales, like Hilton Honors at a 120% bonus or World of Hyatt at 20% off. The guide takes about ten minutes per hotel, so you can check before the window closes.
#3 AwardTravel

AwardTravel offers a points vs cash calculator that covers a long list of loyalty programs. You can choose from major hotel chains like Hilton Honors, Marriott Bonvoy, IHG One Rewards, and World of Hyatt, plus many airline and credit card programs. The form asks for points cost, taxes and fees, and an optional cash price. It then calculates which option is better. The tool is free and does not require a login. It is a handy option if you want one calculator for both hotels and flights.
#4 RoomPoints

RoomPoints packs several free tools into one page. The cents-per-point calculator tells you the exact value of any hotel award redemption. The points vs cash calculator weighs free-night rules, resort-fee waivers, elite-night credit, and points-earning opportunity cost. There is also a sweet-spot finder that ranks hotels by cents-per-point across Hyatt, Marriott, Hilton, and IHG. Each tool is designed to answer one question at a time. No signup is required, and the math is shown clearly.
#5 RewardPointsCalculator

RewardPointsCalculator answers the points vs cash question net of the points you would earn back by paying cash. It builds in each program's free-night rules, fee waivers, and card discounts. You can pick from Hyatt, Marriott, IHG, Hilton, and Wyndham. Each program has its own calculator with the relevant rules baked in. For example, Marriott includes fifth night free and dynamic pricing, while Hilton includes fifth night free for Silver elites and above. It is a detailed option if you want a more complete comparison.
How to Pick the Right Tool
Start with what you need. If you want a quick answer for a single stay, a simple calculator like The Points Guy or AwardTravel works fine. If you are specifically wondering whether buying points is cheaper, SideDoor is built for that. If you want to compare multiple redemptions or find sweet spots, RoomPoints gives you more tools. If you care about free-night rules and fee waivers, RewardPointsCalculator bakes those in. Think about how often you travel and how deep you want to go. A free calculator is enough for occasional trips. A guide like SideDoor makes sense if you book several award stays a year and want a repeatable process. No single tool is right for everyone.
Making It a Habit
Checking the third price does not have to be a chore. Save the booking screens for your favorite chains. When you have a stay in mind, pull the four numbers: cash rate, points rate, points needed, and the cost to buy points. Run them through a calculator. If buying points wins, check award availability before you buy. Set a reminder for limited-time point sales, since bonuses can make the math work. Do this for your next three stays and it becomes second nature. The ten minutes you spend can save hundreds.
The Bottom Line
Hotel rooms have a third price, and most people never check it. The five tools here help you find it. SideDoor is the most focused on the buy-points angle, with a guide and calculator for Hilton, Marriott, IHG, and Hyatt. The Points Guy and AwardTravel offer broad, free calculators for quick comparisons. RoomPoints gives you multiple tools in one place. RewardPointsCalculator adds program rules for a more complete picture. Try one on your next stay. You might find the side door is cheaper than the front.
