Claculation Table in HTML

I need a small table (about 2 columns & 6 rows) with values claculated upon one or two input values and some simple formulas (most of them are simple mathematical operations and only a couple of [if] functions. Results should be updated once a new imput value has been entered. Very simple graphs are required in 2 versions of this table (on big and one small) , to be added on a few personal sites and blogs. The excel sheet attached is an example of calculation needed, the real table will have a few more calculations and some more data.
