I think this is more or less the formula for calculating monthly costs (corrections welcome): 0.01S+max(0,7.20*(R-0.0017S)/4) S is number of GB stored R is biggest retrieval in the month 4 is the average number of hours a retrieval For an example with 10TB storage (replace 10000 to change): http://fooplot.com/plot/4pu7u2gpox http://fooplot.com/plot/4pu7u2gpox x is biggest retrieval in GB, y is $/month
