I am currently using a AWS Redshift ra3.xlplus cluster with 2 nodes. The pricing assistant on the resizing screen in the AWS Console say that this configuration costs $1,560/month which gives me 64TB of storage at $0.024/GB/month and "Pay only for the amount of data you store in managed storage".
My use case is sporadically compute intensive, so I would like to scale up to 6 or 12 nodes to speed things up. However, this dramatically increases the estimated monthly price in the resizing summary.
However, I don't need more storage (6 or 12 nodes maxes out at 192TB and 384TB, respectively). Back of the envelope calculations suggest that estimated monthly price is solely dependent on the number of GB used per month. Is this true? If so, does this mean that I will be charged the same amount regardless of how many nodes I have so long as my managed storage footprint does not change?

Yes, this is correct.
BTW, don't use Concurrency Scaling. I am of the view it is a (and expensive) band aid for an improperly operated Redshift cluster (but very nearly almost all Redshift clusters are improperly operated).
