Alright, let’s update and do some math on the best value for the money on getting game pass.
This is the conversion table, it should still be valid:
Currently they don’t offer 12 months of Gold anymore. They used to be the best way to get Ultimate Game Pass months. When they went on sale, they were 22,500, which translated to 4 months of Ultimate GP, which would normally be $60, so that’s 375ppd, but that’s too good to come back, and they haven’t offered the 12 months of Gold even as a normal reward for a while now, so let’s see what’s currently the best.
I’ll calculate points per dollar (ppd) based on the equivalent retail money you would spend on UGP.
Gold 3 months (2 months UGP) - 20,000 points - 667 ppd
Game Pass PC 3 months (2 months UGP?) - 20,400 points - 680 ppd
Game Pass Ultimate 3 months - 35,000 points - 778 ppd
So right now it’s still the best value to get Xbox Live Gold through the points in order to increase your UGP time. Note Game Pass for PC - 3 months is not on the conversion chart, since it didn’t used to exist when Microsoft did the conversions initially. I’m assuming you will 2 months of UGP, since one month for PC used to be the same as one month for Xbox (20 days).
Now, according to this thread, the last time UGP went on sale back in March, it was on sale for:
Hot Deal 3 Months Ultimate Game Pass - 24,500 points - 544ppd.
So that’s actually the best deal that we know of right now, and worth waiting for. But if you need some UGP time before then, 3 months of Gold is currently the cheapest conversion.
Edit: I should also add that spending points on Ultimate Game Pass is a much better value all around than spending points on Microsoft/Xbox Gift Cards. Even the best Gift card values when they are on hot deal sales are 800ppd. And they’re normally 920ppd if you buy a lot of them.
