How can I calculate standard precipitation index?

RDIT can calculate eight indices of meteorological drought. You can draw graphs and estimate severity, onset, and end of each period's drought. Input and output data are in excel format file. For input data, RDIT is smart. It can assess your data and check blank cells and produce data for 'null' cells. This software calculates SPI (Standardized Precipitation Index), DI (deciles index), PN (Percent of Normal Index), RAI (Rainfall Anomaly Index), EDI (effective drought index), CZI(China-Z index), MCZI (modified CZI), ZSI (Z-Score Index) in form of yearly, seasonally, monthly and moving average for 3, 6, 9, 12, 18, 24, 48 months.
