Frequently asked questions
How much should I tip?
Standard tipping in North America is 15-20% for sit-down restaurants. 18% is the most common default. For exceptional service, 20-25% is appropriate. For takeout, 10-15% is typical. For delivery, 15-20% plus consideration for distance and weather. For bars, $1-2 per drink or 15-20% of the tab.
How do I calculate a tip without a calculator?
For 10%, move the decimal point one place left ($45.00 → $4.50). For 20%, double that ($4.50 × 2 = $9.00). For 15%, add half of 10% to the 10% amount ($4.50 + $2.25 = $6.75). For 18%, calculate 20% and subtract a small amount.
Should I tip on the pre-tax or post-tax amount?
Etiquette experts are divided, but tipping on the pre-tax amount is technically correct. However, most people tip on the total including tax for simplicity. The difference is usually small — on a $50 bill with 13% tax, tipping 18% pre-tax vs post-tax differs by about $1.17.
