Hi @ELees, this functionality is not in Square. It would be a nice feature to implement, especially if it would allow sellers to donate the proceeds to some sort of charity like big box stores do.
Only way around this right now would be to create an item called "Round Up" with a variable price, and put the calculation yourself. if the customer agrees to the round up, just add the item to the cart and do the math. This way they can also see they rounded up.
