Since it scales somewhat close to linear, you can just calculate it yourself.
And since you pay per minute on EC2, you can either chose to have 10 instances calculate a minute or 1 instance for 10 minutes. Either way, you pay for 10 minutes of processing time.
p.s. simplified but probably somewhere in a reasonable ballpark
It's actually rounded up to complete hours, so 10 instances for a minute is 10x the price of 1 instance for 10 minutes.
For fast iterative development this isn't an issue - you can re-use the job flow (the instances you spun up), so you can launch the job several times over the course of that hour.
