How the split works
The tip is calculated as a percentage of the bill amount, added to the original bill to get the total, then divided evenly by the number of people entered. This gives an equal-share amount per person, which is the most common way groups split a bill regardless of what each person individually ordered.
Typical tipping guidelines
Tipping norms vary widely by country and type of service — restaurants in the US commonly expect 15 to 20 percent, while many other countries have lower expectations or a service charge already included. When in doubt, check the bill for an existing service charge before adding an additional tip on top.
Frequently asked questions
Should I tip on the pre-tax or post-tax bill amount?
Conventions vary, but many guides suggest tipping on the pre-tax subtotal. Enter whichever amount you intend to base the tip on — the calculator simply applies the percentage to whatever number you input.
What's a reasonable tip percentage?
This varies significantly by country and type of service. In the US, restaurant tipping commonly falls between 15–20%, while other countries may have lower norms or a service charge already built into the bill — check your bill before adding extra.
How does splitting the bill work if people ordered different amounts?
This calculator splits the total evenly across everyone, which works well for shared meals. If people want to pay based on what they individually ordered, you'd need to calculate each portion separately before adding a proportional tip.
Can I use decimal amounts for the bill?
Yes, the bill field accepts cents (like 42.75), and the tip and total will calculate to the cent as well.
