Reading the order

Cost across three years decided the Maryland card. The method puts 25% on cost across three years and 25% on coverage of the price, then shares 50% among renewal terms, state-by-state fit and pricing clarity.

Maryland Registered Agent.co tallies $297 across three years, $150 below Mainstay Filing. If Maryland is the only state, fifty-state coverage adds little, and the lower yearly price takes the points.

Every criterion and weight appears on How we rank.
