About this tool

The US convention is unforgiving: 15–20% for table service, more for great service, and splitting gets messy fast. This calculator keeps it simple — slide the tip from 0 to 30% or tap the quick 10/15/18/20 buttons, set how many ways the bill splits, and read the tip amount, the total and the per-person figure live as you type. No signup, no ads between you and the number, and no data leaves the page: every calculation is local arithmetic in your browser. Also handy for delivery drivers, salon services and coffee-shop rounding decisions. Everything runs locally in your browser — nothing is uploaded, nothing is sent to any server, and closing the tab erases it all.
