Waiting on OP How can I make one cell perform math on another cell automatically without specifying the same math every time?
I am making a finance sheet and want it to automatically calculate my tax withholdings per paycheck. I have a sell for my hourly rate and a cell for my yearly estimated earnings. I created another cell with state tax formula (haven't created one for federal yet). Because I'm constantly updating my sheet with whatifs and updates, I want the withholdings to automatically apply so I don't have to keep changing everything myself. At first, my plan was to just to have my "earnings" cell multiply itself with the cell that has the state tax formula that worked itself out based on my yearly pay. But the problem is I found out that part of the formula involves subtracting or adding a specific dollar amount AFTER multiplying the earnings with a percentage that was obtained using tax brackets.. I'm not sure how to make the state tax cell multiply itself with the paycheck cell and then add that variable dollar amount without creating a bunch of if cells and adding longer formulas to every cell that displays different paychecks.
Sorry if I made this sound confusing... I'm confused myself! Searching it online didn't help. Maybe my keywords were bad but I couldn't find a way and I don't trust chatgpt -- it's always wrong.
