Pro Tips
- ✓Rounding: It's polite to round the 'Total Per Person' up to the nearest dollar to make payment easier for the server.
- ✓Large Groups: Check your receipt! Many restaurants automatically add an 18% gratuity for parties of 6 or more.
- ✓Pre-Tax vs Post-Tax: Etiquette suggests tipping on the pre-tax amount, but tipping on the total is more generous.
The Math Behind It
Calculating a tip is a simple percentage problem.
The 10% Trick
To find 10%, just move the decimal point one spot to the left.
Bill: $45.00
10% Tip = $4.50
The 20% Trick
Find 10% (move decimal) and then double it.
Bill: $45.00 → 10% is $4.50.
20% is $4.50 x 2 = $9.00.
Splitting the Bill
(Bill + (Bill x Tip%)) / People
$100 Bill + $20 Tip = $120.
$120 / 4 People = $30 each.
Real World Applications
Dining Out (USA)
In the US, tipping is expected.
15-18%: Standard service.
20-25%: Good to Excellent service.
10% or less: Poor service (though usually better to speak to a manager).
Salons & Spas
For hair stylists, barbers, and massage therapists, a 20% tip is standard. If 3 different people worked on your hair (washer, cutter, colorist), it is polite to tip them individually ($5-$10 each) or leave a larger lump sum.
Delivery Drivers
For pizza or food delivery, $3 to $5 is a standard minimum, or 15-20% for large orders. Remember: they pay for their own gas and vehicle maintenance.
Frequently Asked Questions
How do I calculate a tip manually?
To calculate a tip manually, convert the percentage to a decimal (e.g., 20% = 0.20) and multiply it by the bill amount. For a $50 bill and 20% tip: $50 × 0.20 = $10.
Is the tip calculated on tax?
Etiquette experts suggest calculating the tip on the pre-tax amount. However, many people calculate it on the total for simplicity. It's a personal preference.
What is a standard tip amount?
In the United States, 15-20% is standard for sit-down dining. 10-15% is common for other services like delivery or taxis. Outstanding service often warrants 25% or more.
Does splitting the bill affect the tip?
No, the total tip should remain the same percentage of the total bill. Splitting just means each person pays their share of both the bill and the tip.
