Frequently Asked Questions

Multiply the bill amount by 0.20. For a $50 bill: $50 × 0.20 = $10 tip. Total with tip: $50 + $10 = $60.

Standard tip percentages: 15% for adequate service, 18% for good service, 20% for great service, 25% for exceptional service. Some areas or situations may have different norms.

Calculate the total with tip first, then divide by the number of people. For a $100 bill with 20% tip split 4 ways: ($100 + $20) / 4 = $30 per person.

Either is acceptable. Most people tip on the pre-tax amount for consistency, but tipping on the post-tax amount is generous and ensures good service coverage.
