Tip calculator
Calculate the tip on your bill, the total to pay and how much each person owes.
How the calculation works
A tip is a percentage of the bill:
tip = bill × (percent ÷ 100)
total = bill + tip
To split among friends, take the total (tip included) and divide by the number of people.
Step-by-step example
Bill of R$50, 15% tip, 2 people:
- Tip: 50 × 0.15 = R$7.50
- Total: R$57.50
- Per person: 57.50 ÷ 2 = R$28.75
How much to tip (by country)
- US: 15%–20% is expected at restaurants.
- Brazil: a 10% service charge is usually already on the bill and is optional.
- Europe: varies; service is often included and you round up.
Mental shortcut
10% is easy: move the decimal one place. For 15%, add 10% plus half of it. For 20%, double the 10%.
Examples
- Bill R$120, 10%: tip R$12, total R$132.
- Bill $80, 20%, 4 people: total $96, $24 each.
