Dear all,   Can you please help me understand the difference between the output in SAS vs Excel when using NPV function? I have the below example:   No Cashflow 1           6000 2           5000 3           4500 4           4000 5           3500 6           2500     Rate 5.53%   When computing NPV in SAS : NPV=(rate, freq, cashflows) -> NPV =(5.53%, 6,  6000,5000,4500,4000,3500,2500)=25495.37.   The excel output is NPV=21713.68.   I can not figure out the difference or if i computed wrongly in SAS.   Thank you very much, ...
