The formula this calculator uses
Tip, total, and per-person split
Tip = (Tip% ÷ 100) × Bill
Total = Bill + Tip
Per Person = Total ÷ Number of people
Example: $50 bill, 18% tip, 2 people → Tip = $9, Total = $59, Per person = $29.50
Why tipping percentages vary so much
Tipping customs differ enormously by country and by type of service, which is why there's no single "correct" percentage. In the United States, sit-down restaurant tips commonly range from 15% to 20%, while in many European countries a smaller tip, or none at all, is standard because service charges are often already built into the price or added automatically to the bill. Knowing the local norm before you sit down avoids both under-tipping, which can be seen as rude, and over-tipping, which isn't expected or necessary.
Tipping on the subtotal vs. the total
A detail worth checking is whether to tip on the bill before or after tax is added. Tipping on the pre-tax subtotal is the more traditional approach, since the tax itself isn't part of the service being rewarded, but many people simplify the math by tipping on the final total instead. The difference is usually small, but on a large bill it can add up to a meaningful few dollars either way.
Splitting a bill fairly among a group
Dividing a total evenly is the simplest way to split a bill, but it isn't always the fairest one — someone who ordered a salad and water ends up paying the same as someone who had a steak and two drinks. For a truly fair split, each person's individual order total (plus their proportional share of tax and tip) needs to be calculated separately. The even-split method built into this calculator works best for groups who are comfortable rounding the difference out between friends rather than itemizing every receipt line.

Frequently asked questions
How do I calculate a tip?
Multiply the bill amount by the tip percentage divided by 100. A 20% tip on a $50 bill is (20 ÷ 100) × 50 = $10.
How do I split a bill and tip between people?
Add the tip to the bill to get the total, then divide that total by the number of people sharing it.
What's a typical tip percentage?
Common tip rates range from 10% to 20% depending on the country and type of service, with 15-20% common at sit-down restaurants in the US.
Should I tip on the pre-tax or post-tax amount?
Conventions vary, but tipping on the pre-tax subtotal is common practice in many places, since tax isn't part of the service being tipped.
