How to calculate a bar tip
Enter the bar tab and choose a percentage or custom rate. The calculator shows the voluntary tip and final amount immediately.
The Emily Post Institute currently lists $1 to $2 per drink or 15% to 20% of the tab as common U.S. bartender references. Those are two different ways of thinking about the same decision, so a percentage calculator is most useful when you want to compare the tab-based option.
Per drink versus percentage of the tab
A flat amount per drink is simple for a short order. A percentage scales more naturally when the tab includes cocktails, food, multiple rounds, or higher-priced items.
For example, 20% of a $25 tab is $5, while 20% of an $80 tab is $16. The calculator makes the percentage result explicit so you can compare it with any flat amount you had in mind.
Quick examples
| Bar tab | 15% | 20% |
|---|---|---|
| $20 | $3.00 | $4.00 |
| $40 | $6.00 | $8.00 |
| $60 | $9.00 | $12.00 |
| $100 | $15.00 | $20.00 |
Food, table service, and automatic charges
If the bar tab also includes table service or a required service charge, review the receipt before adding another amount. A mandatory fee is not automatically the same as a voluntary tip. The Service Charge vs. Tip guide explains why keeping those lines separate is useful.

When I use per-drink mode
Per-drink mode is easiest to understand when the order is short and I already want to use a fixed dollar amount for each drink. For four drinks at $2 each, the calculator shows an $8 total tip. That result is intentionally independent of the drink prices because the input is a flat amount per drink.
For a longer tab, food service, or higher-priced cocktails, I usually compare that flat result with the percentage mode. A $60 tab at 18% is $10.80 and at 20% is $12, so the comparison can be materially different from a fixed per-drink total.
The receipt check I make before closing the tab
Before I add a voluntary amount, I check whether the receipt already includes an automatic service charge, event fee, or gratuity. I keep required charges separate so I can see the amount already included before deciding whether to add anything else.
If the tab is really a full restaurant check with table service, tax, and group splitting, the Restaurant Tip Calculator has the more relevant fields. For a simple bar tab, this page keeps the decision focused on tab percentage versus a flat amount per drink.
