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.
