Tip on pre-tax or post-tax?
- Pre-tax tip is the old-school US standard: tip only on the cost of what you ordered, not on sales tax the restaurant has to remit.
- Post-tax tip is increasingly the default because many POS systems calculate suggested tips on the total (including tax). A few percent larger tip, mathematically equivalent to a slightly higher tip percentage on the subtotal.
Most serving staff don’t mind which method — they care about total amount. Use whatever keeps your math simple.
Rounding conventions
- Up to the nearest dollar after tip is common US practice.
- Round the total to a clean number: tip goes up by a dollar or two to land at $50 or $60.
- In cash-only settings, tip in cash for 100% retention by the server (credit tips can take weeks to clear and may be shared).
When the bill is service-charge included
Some restaurants auto-add a 15-20% service charge for groups of 6+. Check before tipping again; double-tipping is common in groups who missed the line on the bill.
Large parties
For 8+ diners, restaurants often require a minimum gratuity (gratuity included, usually 18-20%). Confirm what’s on the bill before calculating a separate tip.
Frequently Asked Questions
For sit-down restaurants: 18-22% is the normal range, with 20% being the “default good service” amount. Takeaway and counter service: 10-15% is typical. Some cities (NYC, SF) skew a few points higher.
It’s up to you. The server doesn’t care; tax doesn’t affect them. Tipping on pre-tax saves a small amount of money; tipping on post-tax is simpler and what most POS terminals suggest.
In the US, the standard is to tip 10-15% even for mediocre service, because servers rely on tips for their wage. For genuinely bad service, mention it to the manager — zero tip is an unusual statement that will be remembered.
