# What rounding everything up would be worth

Two cents a cash sale. Quantified here because the number is the argument — and no jurisdiction has adopted it for retail.

**Rounding every cash total up is worth 2.00¢ per transaction, or $20.00 per thousand cash sales. That is a price increase charged only to cash customers, and no jurisdiction has adopted it for retail. It is here to show the size of the prize, which is small.**
