How much should I tip?

In the US, 15-20% is standard for restaurants. 15% for adequate service, 18-20% for good service, and 25%+ for exceptional service. Tipping customs vary by country.

How do I quickly calculate a 15% tip?

Find 10% by moving the decimal point left, then add half of that. For a $60 bill: 10% = $6, half = $3, so 15% = $9.

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

Etiquette experts generally say either is acceptable. Tipping on the pre-tax amount is technically more correct, but many people tip on the total for simplicity.

How do I split a tip between multiple people?

Calculate the total tip, then divide by the number of people. For a $9 tip split 3 ways: $9 ÷ 3 = $3 per person.

An 18% tip on 50 is 9, for a total of 59.

An 18% tip on 50 is 9, giving a total of 59. A tip is simply a percentage of the pre-tip bill.

How to Calculate a Tip

Tipping customs vary worldwide, but the math is universal. In the United States, standard tips range from 15% to 20% at sit-down restaurants, while 10% is common for counter service. Some countries include a service charge automatically, making an extra tip unnecessary. Regardless of local norms, this calculator gives you the exact amount in seconds.

The Formula: Tip Amount = Bill × (Tip% ÷ 100)

Tipping Scenarios

Restaurant dinner: A $95 dinner with 20% tip: $95 × 0.20 = $19.00 tip, total $114.00.
Coffee shop: A $6.50 latte with a 15% tip: $0.98 — round up to $1.00 for convenience.
Taxi ride: A $32 fare with 18% tip: $5.76 tip, making the total $37.76.
Hair salon: A $120 service with 20% tip: $24.00 — a standard show of appreciation for personal services.

Quick Mental Math Trick

To estimate a 15% tip mentally: find 10% (move the decimal one place left), then add half of that. For a $60 bill: 10% = $6, half of that = $3, so 15% ≈ $9. For 20%, just double the 10% figure — $12 on a $60 bill. This calculator removes the guesswork entirely.
