Yes, you can use IHG One Rewards points for car rentals, but not directly through IHG. The points are redeemed through the IHG Points & Money option for booking a rental car via the IHG portal, or by transferring your points to a partner loyalty program like MileagePlus® (United ) or MileagePlus®.
The most straightforward method is using the IHG travel portal. After logging into your IHG One Rewards account, navigate to the "Cars" section. Here, you can book a rental vehicle and at checkout, you'll see a Points & Money option. This allows you to offset the cost of the rental by using a combination of your points and a credit card. The value you get per point can vary significantly based on the rental company, location, and dates.
Alternatively, you can transfer IHG points to partner programs like United MileagePlus. IHG often runs transfer bonuses, sometimes offering a 1:1 ratio plus a 20-50% bonus. Once transferred, you can then use those airline miles to book a car rental through the airline's own travel portal. This indirect path can sometimes yield better value, but it requires more steps and the value is dependent on the airline's redemption rates.
It's crucial to understand that redeeming points for car rentals rarely offers the best value compared to using points for hotel stays. IHG points are typically most valuable when used for their intended purpose: booking hotel rooms, especially with promotions like PointBreaks where rooms can be as low as 5,000 points per night. Before using points for a rental car, always calculate the cents-per-point value to ensure it's a good deal. A redemption value of around 0.5 cents per point is generally considered the baseline for an acceptable use.
| Rental Car Scenario | Estimated Cash Price | Points Required (Example) | Cents-Per-Point Value | Recommendation |
|---|---|---|---|---|
| Economy Rental (3 days) | $180 | 36,000 | 0.5 cents | Poor Value |
| Standard Hotel Night (IHG) | $150 | 30,000 | 0.5 cents | Baseline |
| Premium Hotel Night (IHG) | $300 | 40,000 | 0.75 cents | Good Value |
| PointBreaks Hotel Night | ~$100 | 5,000 | 2.0 cents | Excellent Value |
| Using Transfer Bonus for Flight | Varies | Varies | Can exceed 1.0 cent | Situation-Dependent |
Ultimately, using IHG points for a car rental can be a convenient option if you have a surplus of points and an immediate need. However, for maximizing the value of your rewards, saving points for hotel stays is almost always the smarter financial decision.

You can, but it's usually not the best move. I checked this last time I needed a car. You go through the IHG website's travel section, and they let you use points to pay for part of the cost. The value you get for each point felt pretty low compared to what I can get for a hotel night. I'd only do it if I was desperate and had points to burn. Otherwise, just pay cash for the rental and save your points for a nice hotel stay.

Technically, yes, there is a path. The key is partner transfers. IHG lets you transfer points to certain airline programs, like United. If there's a transfer bonus, that can be interesting. Then, you'd use those airline miles to book a car through the airline's portal. It's a bit of a hassle, and the value isn't always clear. It’s a clever trick for points enthusiasts, but for most people, the direct hotel redemption is simpler and more rewarding.

As a frequent traveler, I look at the opportunity cost. IHG points are a currency. Using them for a car rental often gives you less than half a cent per point in value. I've seen my same points get me over a cent per point on a well-timed hotel booking. So while the option exists in the IHG portal, it's an inefficient use of that currency. Pay for the rental car with a card that offers primary rental insurance and earn more points on the purchase instead.

For a family vacation, we considered it. The IHG portal shows you the points price right next to the cash price. For our week-long minivan rental, the points cost was huge. We did the math and realized we'd be wiping out points that could pay for several hotel nights on a future trip. We decided to pay for the rental and saved the points. The flexibility of having points for a last-minute hotel stay is more valuable to us than covering a rental car.
