Need help with an ROI Calculator

[2Clicks70]

I've created a basic ROI calculator but wish to add a variable input which delays the return on investment impact until training and other services are up and running

I need to know what formula I should use to delay the benefit starting from month 1 (as it does currently) and start it using the cell input for the number of months to delay beginning the benefit

Is there anyone out there that can help?

So if ('VERICUT ROI Calculator'!C18) = 2 then the CGTech Savings (all rows from b7 to b12 move to D7 to D12 i.e. begin in Month 3 rather than 1 as it does now)

It would be different for each row, but something like this in B7:
=IF(COLUMN()-1<='VERICUT ROI Calculator'!$C$18,0,IF(COLUMN()-2='VERICUT ROI Calculator'!$C$18,'VERICUT ROI Calculator'!$C$10,A7+'VERICUT ROI Calculator'!$C$10))
Then you could drag that to the right.
