Tip Percentage Calculator
Compare tip amounts and totals side by side across every common percentage rate.
What is a good tip percentage to choose?
For US restaurants, 20% is the most common rate for good table service, 18% for standard service, 15% for basic service, and 25%–30% for exceptional hospitality or small checks where a flat dollar floor makes sense.
Tip Percentage Conversion Formula
- Tip Amount = Bill Amount × (Percentage ÷ 100)
- 15% = Bill × 0.15 | 18% = Bill × 0.18 | 20% = Bill × 0.20
- Effective Tip Rate = (Actual Tip Paid ÷ Tip Base) × 100
