Rather than converting my several months of remaining Gold into Game Pass Ultimate, the $1...

If you're buying Ultimate while you already have Gold (and/or regular Game Pass) it will convert the remaining time you have into Ultimate at a rate of 1:1. So if you have 12 months of Gold and buy 1 month of Ultimate, you end up with 13 months of Ultimate.

If you go the opposite direction and have Ultimate and then add 12 months of standard Gold or Game Pass, the Gold is converted based on price rather than time. 12 months of Gold is equal to 4 months of Ultimate.

It will convert to Game Pass Ultimate, but as 2 months of Ultimate. The Gold would be converted based on price rather than time.

If you add standard Gold/Game Pass while you have Game Pass Ultimate, the subscription is converted to Ultimate as well. The time is converted based on price rather than time so 12 months of Gold would have been converted to 4 months of Ultimate.

The remaining Gold you have will be converted into Game Pass Ultimate. So for example if you have 6 months of Gold left and buy a 1 month Game Pass Ultimate, you'll have 7 months of Ultimate.

My name is Fernando I'm an independent consultant, I'm happy to help.

I'm going to pass on the information about the new conversion rules:

1-Xbox Live Gold and PC Game Pass Conversion Ratio: Remaining time will be converted to Xbox Game Pass Ultimate time at a 3:2 ratio and rounded up to the next full day. For example, any remaining 90 days of Xbox Live Gold or PC Game Pass will convert to 60 days of Xbox Game Pass Ultimate.
2-Xbox Game Pass Console Conversion Ratio: Remaining time will be converted to Xbox Game Pass final time at a 4:3 ratio and rounded up to the next full day. For example, any remaining 90 days of Xbox Game Pass for Console will convert to 68 days of Xbox Game Pass Ultimate.
3-EA Play Conversion Ratio: Remaining time will be converted to Xbox Game Pass Ultimate time at a 3:1 ratio and rounded up to the next full day. For example, the remaining 90 days of EA Play will convert to 30 days of Xbox Game Pass Ultimate. Gold to Ultimate
