Years of Potential Life Lost (YPLL): YPLL estimates the average time a person would have lived had he or she not died prematurely.It is the duration of life in the absence of the event. A measure of premature mortality.



where Li is the life expectancy at age ‘i’ and di is the number of deaths at age ‘i’. The deaths are weighted by the life expectancy at each age.



where Pi,r is the population in the ith age group and Nr is the total population . Pi is the population affected by COVID-19 in the ith age group in and N is the total population affected by COVID-19.

The COVID DALY calculator is a free, open-source GUI for the calculation of disability-adjusted life years (DALYs), Years of Potential Productive Life Lost (YPPLL), Cost of Productivity Lost (CPL), Years of Potential Life Lost (YPLL), Premature Years of Potential Lost, Working Years of Potential Life Lost (WYPLL), and Value of Statistical Life (VSL), and the quantification of relates uncertainties. The calculator is developed in HTML environment for statistical computing. The main goal of the COVID DALY calculator is to provide a generic and easy-to-use tool for DALY calculations and it’s extensions, and to promote consistency in the uncertainty analysis of COVID DALYs. The results provided by this calculator will depend on the accuracy of the data inputs and will be the responsibility of the user.
