What Is a Tip Calculator?
A tip calculator figures out how much to tip on a restaurant bill or service, and splits the total evenly between any number of people — handy for group dinners, rideshares, or salon visits.
How to Use the Tip Calculator
- Enter your bill amount before tip.
- Pick a common tip percentage or enter a custom one.
- Enter how many people are splitting the bill.
- See your total tip, grand total, and per-person amount instantly.
Tip Calculation Formula
Worked Example
Bill amount: $60.00
Tip percentage: 18%
Tip amount: $60 × 0.18 = $10.80
Grand total: $70.80
Split 3 ways: $23.60 per person, including a $3.60 tip share each.
Understanding Your Results
Total Tip is the dollar amount of gratuity on the whole bill. Grand Total is the bill plus tip. Total Per Person and Tip Per Person divide those evenly across everyone splitting the check.
Typical Tipping Guidelines (US)
| Service | Typical Tip |
|---|---|
| Sit-down restaurant | 15–20% |
| Casual / counter service | 10–15% |
| Delivery | 10–15% (min $3–5) |
| Hair salon / barber | 15–20% |
| Rideshare / taxi | 10–20% |
Tipping customs vary significantly outside the US — in many countries, tipping is smaller, optional, or already included as a service charge.
Common Mistakes to Avoid
- Tipping on the post-tax total instead of the pre-tax bill (either is acceptable, but be consistent).
- Forgetting to account for large groups, where some restaurants auto-add gratuity.
- Splitting unevenly when orders were significantly different sizes — consider itemized splitting for large price gaps.
