Tip calculator
Custom: 18%
Enter a valid bill to see tip math.
Key takeaways
- Slider plus presets cover most US dining norms in one thumb motion.
- Split field helps crews on a shared company card after a job lunch.
- No sign-in — works when cellular is weak after first load.
- Useful for field teams who rarely carry a dedicated calculator app.
- Rounding in display is two decimal places — cash rounding still manual.

Frequently asked questions
Does this include tax?
Enter the bill total you want to tip on — if your receipt shows tax separately, either include tax in the amount you type or run the tool twice for transparency with your party. The math itself does not know your local tax rules.
Why preset buttons at fifteen, eighteen and twenty percent?
Those are common US restaurant defaults. The slider still lets you pick any whole percent between zero and forty for delivery, large groups or international norms.
Is data sent to a server?
No. All numbers stay in your browser session. Refresh clears them unless your browser restores form fields.
What if I split unevenly?
This version assumes an even split for speed. Uneven shares still belong in a spreadsheet or cash app after you agree who covers rounding.
