Do ENERGY STAR Most Efficient dishwashers cost less to run?

In this sample, yes. Median running cost by certification status is ENERGY STAR Most Efficient: $37.40 across 10 models, ENERGY STAR Certified: $40.80 across 70 models. Certification is relative to product class, so size still matters more than the label when comparing two specific models.

How are the running costs for these dishwashers calculated?

Each of the 80 dishwashers listed here uses the annual kWh reported for that exact model in the EPA ENERGY STAR certified dataset, multiplied by a flat $0.17/kWh. For this category that produces a range of $35.70/yr to $40.80/yr around a $40.80/yr median. Nothing here is measured or estimated by this site and no external benchmark is mixed in, so if your local rate differs you can scale every figure by the same factor - the ranking between models does not change.
