How to calculate a tip

Multiply the bill amount by the tip percentage divided by 100. For example, a 20% tip on a $45 bill: $45 × 0.20 = $9.00, making the total $54.00.

Standard tip percentages

10% — counter service, buffets, or below-average service. 15% — standard for adequate service. 18–20% — good service at sit-down restaurants. 25%+ — exceptional service or special occasions.

How to split a bill

Add the tip to the subtotal to get the full total, then divide by the number of diners. The calculator above handles this automatically — change the People field to any number.
