Tip Calculator

Figuring out a fair tip, and then splitting the total evenly across a table of people, is a small piece of mental math that's easy to fumble under a waiter's watchful eye or after a few drinks. This calculator handles both steps at once: enter the bill amount, pick a tip percentage, and set how many people are splitting the check, and it instantly shows the tip amount, the grand total, and exactly what each person owes.

The tip percentage can be set two ways: drag the slider for fine-grained control, or tap one of the quick-pick presets (10%, 15%, 18%, 20%) for the percentages people reach for most often. Both stay in sync with each other, so tapping a preset moves the slider to match, and dragging the slider updates which preset (if any) is highlighted. The people count uses a simple +/− stepper, from a single diner up to a large group, and every figure on screen (tip amount, total with tip, and per-person share) recalculates live as you adjust any input, with no "Calculate" button to press.

All the math is the ordinary tip-splitting arithmetic: the tip amount is the bill multiplied by the tip percentage, the total is the bill plus that tip, and each person's share is the total divided evenly by the number of people. Results are always rounded sensibly to the nearest cent for display, so the numbers you see are the ones you'd actually hand over or Venmo to a friend.

Like every tool on this site, the entire calculation runs as plain JavaScript directly in your browser; the bill amount you type is never sent to a server, logged, or stored anywhere. Whether you're splitting a dinner check with friends, tipping a delivery driver, or just double-checking gratuity on a big group bill, the math happens instantly and privately on your own device.
