Warehouse compute credits depend on size and billed running time. For this course, X-Small uses 1 credit per hour, Small 2, Medium 4 and Large 8. Multiply the hourly rate by billed seconds divided by 3,600. Every resume has a 60-second minimum, so many short starts need a different estimate from one continuous run.
Estimate credits before converting them to money. A currency amount needs the account's contracted credit price, which this course doesn't supply. Storage and some serverless services also sit outside the warehouse calculation. A larger warehouse can finish sooner, but you need measured elapsed time to decide whether its credits decrease. Size alone can't establish that comparison.
