How to Use This Tip Calculator
- Type your bill amount. Use the total before tip — that's what the percentage applies to.
- Tap a preset percentage (15%, 18%, 20%…) or enter a custom percent.
- Set how many people are splitting. Toggle "Round up" if you want clean cash amounts.
How a Tip Is Calculated
The math is straightforward. The tip is a percentage of your subtotal, and the per-person amount is the bill plus tip, divided by the headcount.
total = bill + tip
per person = total ÷ people
The "Round up" option rounds each person's share to the nearest dollar. The extra cents are absorbed into the tip total, so nobody at the table comes up short and the server gets a slightly better tip.
Why a tip calculator is really a travel tool
The maths of a tip is trivial — a percentage of the bill, optionally split between people. What actually trips people up is how much, and that depends entirely on where you are. In the United States, tipping roughly 15–20% is expected and waitstaff genuinely rely on it. In much of Asia the custom is different: in Japan tipping is essentially not done and can even confuse or embarrass staff, while in many restaurants across Hong Kong and Singapore a service charge (often 10%) is already on the bill — so adding a tip on top means paying twice. This tool handles the split and the percentage; the local norm is the part worth checking before you go.
In 20 years of IT support I worked with teams in Manila, Hong Kong, Japan and Singapore, and tipping was a surprisingly regular source of mild panic whenever people travelled for work. Colleagues heading to the US would ask, half-seriously, how to avoid looking rude at dinner — because back home they'd never tipped in their lives. And visitors coming the other way would try to leave cash on the table in Tokyo and get politely chased down by staff returning it. The honest rule I ended up sharing: don't assume your home habit travels. Check whether a service charge is already added, and whether tipping is even expected, before you reach for the calculator.

How much should I tip at a restaurant?
In the U.S., 18–20% is standard for good service. 15% is acceptable for average service. In Europe a service charge is often included — anything extra is optional.
Do I tip on the pre-tax or post-tax total?
Tipping on the pre-tax subtotal is technically correct, but many people tip on the full post-tax total for simplicity. Either is acceptable in casual settings.
What is the "Round Up" option?
Round Up bumps each person's share to the nearest dollar so cash splits are clean. The extra cents are added to the tip — nobody comes up short.
Should I tip when travelling abroad?
It depends entirely on the country. Tipping is expected in the US (around 15–20%), but in Japan it isn't customary and can confuse staff, and in many places a service charge is already included. Check the local norm before assuming your home habit applies.
