Tip Calculator

How this tip calculator works

This calculator takes your bill amount, applies a tip percentage, and divides the total among the number of people dining. You pick from common percentages (10–25%) or enter a custom amount. The result shows the tip, the grand total, and each person's share — useful for splitting a check fairly.

The tip math

tip = bill × (percent ÷ 100)

total = bill + tip

per person = total ÷ number of people

Where the percentages come from

• 15% — minimum for adequate table service
• 18% — standard for full sit-down service in most US cities
• 20% — generous, or baseline for great service
• 25%+ — exceptional service, large parties, or small inexpensive checks

Tipping smarter

• Tip on the pre-tax subtotal — sales tax isn't part of the service
• For groups, many restaurants add an automatic 18% gratuity for 6+ guests
• If using a discount or coupon, tip on the original full price
• For takeout, 10% is appreciated but not required
