Last year the Postal Service modified pay policy concerning promotional increases for non-bargaining unit employees promoted to higher grades. The changes announced in June of 2015 provide for a percentage increases based upon the salary distance from the maximum of the new EAS grade and a percentage increase if the promotion is three EAS grades or more. 
To assist Postmasters and Managers in determining a potential percent of salary increase for a promotion, the Postal Service has developed a Promotional Pay Calculator. The calculator will take much of the mystery out of the methodology used to determine raises and provide valuable information to all non-bargaining unit employees considering applying for promotion.
To use the calculator, complete requested information in the section titled; Enter Employee Information, located in the lower right corner of the form.
The calculator will be included on our website under references documents.
