calculating percentages

I am not Excel savvy. I am creating a simple spreadsheet to calculate the application of annual salaries and benefits to contracts based upon that contract's percentage of total revenues. I have entered total contract revenues, the number of months the contract is active in 2010, the number of months the contract is active in other years, then used a formula to calculate the percentage of the contract revenues applicable to 2010. I have the percentages expressed in whole numbers as I want to keep this "broad brush strokes." All that works fine. However, I then want to express those "round number" percentages in terms of dollars by using formulas. However, when I do that, Excel calculates the dollars using precise percentages (for example, using 54.55%) rather than the whole number percentage (55%). I have attached a portion of the spreadsheet to illustrate the formulas I am using. Can someone please help me use formulas to express the dollars using whole percentage numbers rather than the (actual) fractional percentages? THANK YOU!!!

If you wrap the reference to the cell containing the percentage in a Round() function, it will round to the nearest whole percentage.

e.g. ROUND(A1,0) will round value in A1 to a whole number.

How about this in I10:

=ROUND(G10*100,0)*D10

Sorry.. forgot to divide by 100 again...

=ROUND(G10*100,0)/100*D10

Actually a better way would be:

=ROUND(G10,2)*D10

since a percentage is really a fraction of 1 , eg 54.5% is really 0.545 in excel, we want to round this to 2 decimals.. making .545, .55 and then multiplied by D10.
