How to calculate a tip
Tip = Bill amount × (Tip percentage ÷ 100)
For example, a 20 percent tip on a 50-dollar bill is 10 dollars.
50 × 0.20 = 10
Calculate the total bill
Total = Bill amount + Tip
Split the bill
After adding the tip, divide the final total by the number of people sharing the bill.
Per-person total = Final total ÷ Number of people
Should the tip be calculated before or after tax?
Practices vary by location and personal preference. Some people calculate gratuity from the pre-tax subtotal, while others use the final billed amount.
Tip percentages are not universal
Tipping customs vary substantially by country, service type and local practice. A calculator performs the arithmetic but does not determine what gratuity is expected in a particular situation.
Choose the percentage yourself
Use a tip percentage appropriate to the location, service and your own judgment. CalculatorSquare does not prescribe a particular gratuity rate.
