This page can be used to calculate scores based upon the process originally devised by John Brooke . A total score of more than 68 is considered to be above average . In addition, scores are translated into grades (A, B, C, D, and F) and an approximation of the adjectives specified by the work of Bangor, Kortum and Miller .
Enter your scores, per question, to calculate total SUS score. A score should be given for all questions.
If you do not feel that you can respond to a particular question then mark it at the centre point of the scale.
You need to enter a response to each question.
