How Much Should You Tip?

Tipping customs vary by country and service type. In the United States, here are the widely accepted guidelines:

Pre-Tax or Post-Tax?

There is an ongoing debate about whether to tip on the pre-tax or post-tax amount. Most etiquette experts suggest tipping on the pre-tax total, but in practice the difference is small (a few cents to a dollar). What matters most is that servers are tipped fairly for their service.

Splitting a Bill Fairly

When splitting a bill, divide the total (including tip) by the number of diners. If people ordered very different amounts, consider splitting based on what each person ordered — this calculator handles equal splits, and you can run it multiple times for different amounts.

Frequently Asked Questions

Is 15% still an acceptable tip?+
15% was the standard for many years, but 18–20% is now considered the baseline for good service in most US restaurants, especially in cities. 15% is still appreciated and acceptable for average or counter service. Always tip what you feel the service deserves.
Should I tip on the pre-tax or post-tax amount?+
Tipping on the pre-tax amount is technically "correct" by old etiquette standards, but tipping on the post-tax total is more common and easier. The difference is usually just a dollar or two, so either is fine. When in doubt, rounding up generously is always appreciated.
What is a good tip for takeout orders?+
Tipping for takeout is optional but appreciated. 10% is a reasonable tip for takeout orders, especially from locally-owned restaurants. For delivery orders, 15–20% (or a minimum of $5) is appropriate given the effort and fuel costs involved.
How do I split the bill if some people didn't drink alcohol?+
The fairest approach is to calculate the alcohol separately and divide it only among those who drank. Total up the food, split evenly among all diners, then add each person's drink total to their share. Add tip on top of each person's total.
