A group of 3 friends dining at a restaurant receives an $85.50 dinner bill and decides to add an 18% gratuity tip for attentive service: calculating the tip amount yields $15.39, resulting in a total bill of $100.89. Splitting the total check evenly among the 3 diners reveals that each person pays $33.63 ($28.50 base bill + $5.13 tip share per person). A traveler ordering food delivery calculates tip percentages to reward delivery drivers appropriately.
A tip (gratuity) is a voluntary sum of money given by a customer to service workers (waitstaff, delivery drivers, taxi drivers, barbers) in addition to the base charge for service rendered.
Tipping percentages are calculated as a direct percentage of the subtotal or final post-tax bill amount:
Tip Amount = Bill Subtotal × (Tip Percentage / 100)
Total Bill = Bill Subtotal + Tip Amount
Per Person Total = Total Bill / Number of Diners
This calculator computes tip amounts, total bills with gratuity, per-person split costs, and offers quick 10%, 15%, 18%, 20%, and 25% preset buttons. The following guide covers US tipping etiquette standards, pre-tax versus post-tax tipping practices, and group bill splitting protocols.
When bill inputs are entered, the engine evaluates tip percentages, adds gratuity to the bill subtotal, and divides the total by party size.
1. Tip Amount Formula:
Tip Amount = Bill Amount × (Tip % / 100)
2. Total Bill Formula:
Total Bill = Bill Amount + Tip Amount = Bill Amount × (1 + Tip % / 100)
3. Per Person Split Calculation:
Tip Per Person = Tip Amount / Party Size
Total Per Person = Total Bill / Party Size

| Tip Percentage | Service Quality Level | Common Tipping Scenario |
|---|---|---|
| 10% | Fair / Minimum standard | Buffets, takeout, or basic service |
| 15% | Good standard service | Standard sit-down restaurant dining |
| 18% - 20% | Great / Excellent service | Attentive server, full-service dining |
| 25%+ | Exceptional / Special care | Fine dining, large parties, holidays |
Standard etiquette guidelines recommend calculating tips on the pre-tax subtotal (food and drink charges only). However, tipping on the post-tax total is also common practice.
Many restaurants automatically add an 18% or 20% gratuity to the bill for parties of 6 or more. Check your receipt before adding an extra tip!
The calculator rounds per-person amounts to the nearest cent ($0.01). Any tiny fractional cent remainder (e.g. $0.01 difference across the group) can be covered by one member.
