We add each plan's price, accuracy, cost to get started, bundle and performance scores at their weights and scale the total to 100. Accuracy and performance come from our benchmark, so until we benchmark the provider they are N/A, and so is the plan's overall score. A plan whose accuracy score is 0 has an overall score of 0, whatever its other scores. Click or tap any score to see how we scored it. Move a weight to rank the plans by the new scores.
