I know you set a target balance, but do you keep funding up to the target balance after any expenditures? So, let's say I have a target of $500 for the year in my Gifts category. I put $19. 23 in that sinking fund from each of 26 paychecks during the year. At the end of February, I should have $76. 92. Kid #1 has a birthday party to go to. We spend $20. Then for whatever reason, I have some extra money and want to fully fund my sinking fund. Is fully funded at this point $480 because I spent $20 of my yearly budget or is it still $500. I know I'm overly complicating this, but I can't decide what I want to do.
