Tipping Etiquette Guide
How the Tip Split Calculator Works
I've built this tip calculator to handle the most common restaurant scenarios. Whether you're dining solo or splitting with a group of 20, it handles the math instantly. You don't need to fumble with your phone's calculator at the table anymore — just enter the bill, tap a tip percentage, and see everyone's share.
The standard formula is: Tip = Bill Amount x Tip Percentage, and Per Person = (Bill + Tip) / Number of People. If you enable "Tip on pre-tax amount," the tip is calculated on the bill minus tax, which is technically the more correct approach — but many people just tip on the total for simplicity.
How Much Should You Tip?
In the US, the general standard is 15-20% for sit-down restaurants. I can't stress enough that servers often depend on tips as a significant portion of their income. Here's a quick guide:
- 15% — Acceptable for adequate service
- 18% — Standard for good service
- 20% — Great service or fine dining
- 25%+ — Exceptional service or large parties
Our Testing Methodology
Every calculation in this tool has been verified against manual computations and standard tipping guides. Our testing includes edge cases like very small bills, very large groups, custom tip percentages, and the round-up feature. We also validate the localStorage history system across browser sessions and verify it persists correctly.
