Multiple IF statements

[Wally-sns]

If i want to have multiple IF statements, how would i write the formula?

In other words, here is the following:

IF the Sales total is LESS THAN 100,000...then multiple Sales by 5%
IF the Sales total is BETWEEN 101,000 and 500,000,..then multiple Sales by 6%
IF the Sales total is GREATER THAN 101,000 and 500,000,..then multiple Sales by 7%

Help is much appreciated !

=INDEX({0.5,0.6,0.7},MATCH(A1-0.0001,{-1,100000,500000}))

I'm not familiar with the INDEX equation...can you give me a quick tutorial ?

 

[Wally-sns]

What does the " A1-0.0001 " actually mean and what is it doing ?

 

[Greg Truby]

I know that sometimes the help files can be hard to understand. What part of what's in the Excel help files was unclear?

 

[Wally-sns]

It seems to work great....thanks very very much Greg !

I'm just not understanding what the "A1-0.0001" actually does and why it is there ?

 

[Greg Truby]

Quite welcome. The A1-0.0001 is because otherwise MATCH is going to return the next item in line at the breakpoints. Subtracting a teeny amount makes it so that MATCH will return the "lower" value when A1 is at the breakpoint because the subtraction scoots it just a smidgeon under the threadhold. You could also just adjust the args inside the array so then the formula would read:

=INDEX({0.5,0.6,0.7},MATCH(A1,{0,100000.001,500000.001}))

It's just aesthetics -- which looks prettier. (Some of puritans might say that it's not just aesthetics because the first formula has that subtraction which is one extra operation so there is a performance hit. But the performance hit is akin to the impact of hitting a grasshopper's impact on you gas mileage -- negligable.)

Beautiful....but now how does it know about the greater than , less than, etc....just by only entering the values of 100, 500, etc. ?

Did you look over the help files' info on MATCH()? That's what's providing the 2nd argument into the INDEX() function. You might step through the formula using the formula auditing tool to get a better understanding of it. (Menu option Tools | Formula Auditing | Evaluate Formula)
