Tip = Bill × Tip% Total = Bill + Tip Per Person = Total ÷ Number of People

Worked Examples

$65 bill, 20% tip, 2 people

1. Tip = $65 × 0.20 = $13.00
2. Total = $65 + $13 = $78.00
3. Per person = $78.00 ÷ 2 = $39.00

Result: $13.00 tip, $78.00 total, $39.00 each

$120 bill, 18% tip, 4 people

1. Tip = $120 × 0.18 = $21.60
2. Total = $141.60
3. Per person = $35.40

Result: $21.60 tip, $141.60 total, $35.40 each

Tips & Best Practices

20% is considered standard for good service in the US.
Quick 20% tip trick: move the decimal left one place and double it ($65 → $6.5 → $13).
Tip on the pre-tax amount, not the after-tax total.
For large groups (6+), many restaurants add 18-20% gratuity automatically.

Common Mistakes to Avoid

❌ Tipping on the post-tax amount.

✅ Calculate your tip on the pre-tax subtotal. Tipping on the tax-inclusive total means you are tipping on sales tax, which slightly inflates the tip.

❌ Not adjusting tip for exceptional or poor service.

✅ 15% for adequate service, 20% for good, 25%+ for exceptional. Below 15% sends a message about poor service, but consider speaking to a manager instead.

Frequently Asked Questions

What is a standard tip in the US?

In the US, 15-20% is standard for sit-down restaurants. 20% has become the most common default. For buffets, 10% is acceptable. For delivery, $3-5 or 15-20% (whichever is higher).

Should I tip on the pre-tax or post-tax amount?

Etiquette experts recommend tipping on the pre-tax subtotal. However, tipping on the post-tax total is common and results in a slightly larger (and appreciated) tip.
