What exactly do I have?

https://www.linode.com/pricing

The metered plans have the monthly price in parenthesis.

If you have pending upgrades, then you will want to do them to eventually reach those plans.

Possibly a question for support in your situation (as I don't see a 6GB Linode option), but for me, https://manager.linode.com/linodes shows me my Linodes, with details such as:

Linode 2048

Linode 4096, etc.

Also, https://www.linode.com/pricing - there is monthly pricing below the unit pricing in the first view.

If you click on 'view all plans', the monthly pricing is on the right hand column, just prior to 'sign up'.

Since your vCPU count is going down, you're behind one generation in plan. You're on a plan that has been phased out due to lack of popularity (IIRC), and are grandfathered into. You'll still receive free upgrades like everybody else, but if you resize to a different plan, you can't go back. Because your plan is phased out, there's no details on the pricing page, as it's not available for new customers to purchase so that would just be confusing. You have the Linode 3072, which costs $60/month. In my time at Linode, your plan started as a Linode 1536, and then free RAM upgrades have made it the Linode 3072, and now Linode 6144. It was meant to provide a filler between the $40 and $80 levels, for customers who didn't quite need twice as much RAM when resizing. Hope this helps!

Thanks everybody.

It does look like all my numbers do fall perfectly at where the "6GB" plan would be (except vCPUs is 4 not 5, which is fine)

You're right. How did I miss that?!

Proof that marketing can train your eyes…
