Losses verification ( input losses does not match the calculated losses )

Hello, I want to ask about the losses in losses input page for wind.
 
InWind, Commercial, distributed > in losses page. My losses in % are = 7,5,2,3,2,2 = 21% total. Given as input.
 
But when I am doing the calculation, the given input losses (only losses on the losses page, no degradation) does not match with the given input losses. (excel screenshot is attached.) kindly guide me.

Why input losses do not match with the annual output and gross output.?

See below for calculations= 

AnnualOutput (A) = 9,981,240
GrossOutput ( = 12,374,500
LossesCalculated = B-A = 2,393,260
Lossescalculated = (2,393,260 / 9,981,240)*100 = 23.98% ? why is it so?
I have given 21% losses total!

kindly guide me. 

Hi Hamza Ali,

Be sure to add the percentages as sum of (1-x/100). See the attached Excel workbook.
