Transfer Bonus: 30% More Marriott Bonvoy Points with Your American Express Membership Rewards Points

From September 1 to September 30, 2025, you can earn a 30% bonus by transferring your American Express Membership Rewards points to Marriott Bonvoy:

I did the test by transferring 1,000 Membership Rewards points from my American Express Cobalt^® Card to my Marriott Bonvoy account and I did get 1,560 Marriott Bonvoy points:

• 1,200 Marriott Bonvoy points (usual transfer rate 1:1.2)
• 360 bonus Marriott Bonvoy points (30%)

Usually, 1 Membership Rewards Point = 1.2 Marriott Bonvoy points. But with the promotion, that means 1 Membership Rewards Point = 1.56 Marriott Bonvoy points.

For example, if you transfer 1,000 Membership Rewards points, you’ll receive a total of 1,560 Marriott Bonvoy points (instead of 1,200). Before transferring a large amount of Membership rewards points, do a test transfer of 1,000 Membership Rewards points to make sure the bonus works for you.

For example, the 15,000-point welcome bonus on the American Express Cobalt^® Card can be converted into 23,400 Marriott Bonvoy points.

And if you’re a Marriott Bonvoy cardholder: every purchase in a 5 points-per-dollar category (grocery, restaurants, bars, convenience stores) is worth 7.8 Marriott Bonvoy points when you transfer your points during a promotion of this type. This is an excellent value!

That’s why we consider the American Express Cobalt^® Card one of the best cards for EARNING points via everyday spending.

Another example: the 60,000-point welcome bonus from the American Express^® Gold Rewards Card can be converted into 93,600 Marriott Bonvoy points.

Here, it’s a great way to earn points via the welcome bonus!

We value the Marriott Bonvoy point at 0.9 cents, but it’s possible to get much better value for your points; here are some examples of exceptional stays achieved for few points by the Milesopedia team and Facebook community.

Finally, don’t forget that if you don’t already have one (or both) of the Marriott Bonvoy credit cards, this is a great way to earn even more Marriott Bonvoy points.

This is a great promotion to transfer Membership Rewards points to Marriott Bonvoy for free hotel nights. This is the one we’ve been waiting for!

If previous years are any indication, the next promotion is expected to be in March or April 2026. So take the opportunity to optimize your points now.

As a reminder, you can transfer your Membership Rewards points from any American Express Membership Rewards credit card such as the American Express Cobalt^® Card the American Express^® Gold Rewards Card or the American Express Platinum Card^® to the Marriott Bonvoy program.
