# Help creating a math formula

0

Hi, I need help writing this formula:

how to write a formula for 100,000-3.5% =96,500.  (96,500*1.75%=1688.75) I need the result in that sell to show the total of (96,500+1688.75) 98,188.75.

The 100,000 is in a cell A1 and the 3.5% is in cell A2

the result needs to be in cell A3.

Thanks

Roy

Almost like you wrote it but with an equals sign in front. In Excel, all basic math rules and oerder of operations applies.

``=A1*0.965*(1+A2)``

Thanks for your assistance, with this formula (=A1*0.965*(1+A2)) the answer is coming out at 99,878, it should be 98,189

Glad to have been of assistance. So disappointed though. You missed the chance to give me my first up-vote ever on this site :-)

You didn't tell us where the 1.75% comes from. This formula presumes that it is in A3.

``=(A1*(1-A2))*(1+A3)``

On the other hand, if 1.75% is always half of A2 you might use the formula like this:-

``=(A1*(1-A2))*(1+(A2/2))``

Thank you very much, that was perfect.

rbhiro, if this was the right answer you need to select it by clicking the blue Select Answer button under it.

@cappymer1 - Thank you. It's funny though that I see no "Select answer" button (any colour) on the entire page. Also, all answers have a big, fat 0 at their top left, but mine has no voting arrows above and below that 0. As I said, I'm new here. But is that how it should be?

If you asked the question then you are able to select the answer to it and will see the button. Also, you can't vote on your own answers/questions and that's why you don't see the arrows next to your own answer.

=(A1-(A1*B1)+(A1-(A1*B1)*1.75%
