Calculate tips and split bills instantly. Choose your tip percentage, number of people, and see per-person totals.
Multiply the bill amount by the tip percentage and divide by 100. For example, a 20% tip on an $85 bill: $85 × 20 ÷ 100 = $17.00. Total with tip: $85 + $17 = $102.00.
A quick mental trick for 20%: move the decimal point one place left (10% of bill), then double it. For $85: 10% = $8.50, doubled = $17.00. For 15%: calculate 10% and add half of that. For $85: $8.50 + $4.25 = $12.75.
Standard US tipping: 15% for adequate service, 18% for good, 20% for great, 25%+ for exceptional. These guidelines apply to sit-down restaurants. Other services have different norms.
For takeout: 10-15%. Delivery: 15-20% (minimum $3-5). Bars: $1-2 per drink or 15-20%. Hair salons: 15-20%. Hotel housekeeping: $2-5 per night. Taxi/rideshare: 15-20%. Tipping customs vary significantly outside the US — in many countries, tipping is not expected or is included in the bill as a service charge.
Calculate the total bill including tip, then divide by the number of people. For an $85 bill with 20% tip split 4 ways: total = $102, per person = $25.50.
When splitting unevenly (some people ordered more), calculate each person's share of the food, then add the same tip percentage to each share. This calculator handles even splits automatically — just set the number of people and see per-person amounts instantly.
Note: Tipping customs vary by country and culture. The percentages shown are based on common US practices. In many countries, service charges are included in the bill. Always check if gratuity has already been added before tipping additionally.
