Solution 1

We can't help you directly - we don;t have access to your DB, so we have no idea what values are in the Amount Column for the selected row, and that's fundamental to the calculation.

So start by adding Amount to the SELECT list, and returning that and your calculated value - you can then start to work out what is going on. but that's some weird code: isnull(64400.00,0) and isnull(13,0) are always going to return 64400.00 and 13 respectively ...

Amount Column Value is 3.00

OriginalGriff 3-Mar-20 2:46am

And why do you think that
64400.00 * (Power((1 +(3.0/100)),13)-1)
should be 3087?
64400.00 * (1.030000 to the power 13)-1)
Will be 30173.59 ...

Member 12183079 3-Mar-20 3:52am

because i am calculating like amount percent like 3 percent

OriginalGriff 3-Mar-20 4:09am

3% of what?
3% of 64400 is 1932 not 3087 ...
