Passer Rating Calculator

To use the form below, input passing statistics values in the corresponding boxes. Then, select which passing rating formula you wish to calculate.



"40 Index" (stylized as "40nDX") is a proprietary rating formula developed by Ross Wheatley with the intention to improve upon the traditional passer rating formula. The traditional formula was developed using antiquated and/or arbitrary performance standards. 40nDX reformulates the traditional convention by setting a more appropriate standard of excellent based on the 12 historic seasons in which a quarterback achieved 40 or more touchdowns thrown (hence the 40). A perfect 40nDX rating is 100.
