Cash-Out (Total Rounding): Rounding applies only to the amount due. Tax is calculated exactly, and rounding never changes what tax you owe.

Your Receipt

Amount Due (rounded)$10.85

Rounded down by 1¢

Net-negative adjustment for this transaction

Cash payments are rounded to the nearest five-cent increment. This eliminates pennies while producing statistically neutral outcomes over time.
