Quick Mental Math for Tips
The 10% method (works anywhere)
1. Find 10%: move the decimal point one place left
2. For 15%: add half of 10% to the 10%
3. For 20%: double the 10%
Example on a $67 bill:
- 10% = $6.70
- 15% = $6.70 + $3.35 = $10.05
- 20% = $6.70 x 2 = $13.40
The double-the-tax method (US)
In many US states, sales tax is around 8%. Double it for a 16% tip - close enough to 15-20%.
Rounding for simplicity
On a $43 bill:
- 10% = $4.30
- Round to $4.50 for easy math
- 20% = $9 (double $4.50)
- Want 15%? Split the difference: about $6.75
Splitting the Bill with Tips
When dining with a group:
Equal split
Total bill + tip, divided by number of people.
- Bill: $200, Tip: 20% = $40
- Total: $240 / 6 people = $40 each
Proportional split
Each person tips on what they ordered:
- Person A ordered $35 food, tips 20% = $7, total = $42
- Person B ordered $65 food, tips 20% = $13, total = $78
Common issues with group tips
- Always tip on the FULL amount, including your share
- Avoid the "I only had a salad" trap - cover your fair share of shared items
- Designate one person to calculate to avoid under-tipping
When to Tip More or Less
Tip more (20%+) when:
- Service was exceptional
- You have a large group (extra work for the server)
- You stayed an unusually long time
- There were special requests or dietary accommodations
- It is a holiday
Acceptable to tip less (10-15%) when:
- Service was notably poor (but still tip something)
- It is counter service or takeout
Never acceptable to skip tipping entirely (in tipping cultures):
- If you received table service, tip
- If you cannot afford to tip, you cannot afford to eat out
Pre-Tax vs. Post-Tax Tipping
In the US, the proper etiquette is to tip on the pre-tax amount:
- Bill: $50 food + $4.50 tax = $54.50
- 20% tip on pre-tax: $50 x 0.20 = $10
- 20% tip on post-tax: $54.50 x 0.20 = $10.90
The difference is small, but on large bills it adds up. Either is acceptable.
