Subtract from column based on value from another column

Ok so what I am trying to do is I have a spreadsheet that has a sumif function in it based on different category names, what I want to do is if that column gets over a certain amount I want to take that value and subtract it from another cell.

Column A Column B

Utilities 300.00
Rent 500.00

The threshold for utilites is $300 so if it goes over that say to $350 the value for rent should drop to $450

I did try to write a simple formula but I'm missing something, here is the formula I wrote: =IF((B3>300),(=sum(B4-B3)))

This should do it
=IF(B3>300,B4-B3+300,B4)

Didn't get that at first the part where you are adding 300 but I think I just figured out that you are adding back in the value of B3 to keep the total value consistent at 800

Yes thats corrcet! thsi way the formula will reduce rent if and only if utilities exceeds 300 by an amount that utilities is over 300

Does this work for you?
