The test

Calculated three-year cost (41%): Year one plus two renewals using each company's published prices.
Filing work in the price (27%): The recurring jobs the price handles: registered agent, state report, EIN application and availability in other states.
Renewal change (13%): The shift between the year-one price and the renewal price.
Break-even year (10%): The year one service's running total goes past another's, found by the calculator on each page.
Input clarity (9%): Whether the first-year price, renewal and state fee are all published so the inputs can be checked.
