Tip Calculator
Enter the bill, pick a tip percentage and split it between any number of people - every figure updates as you type.
How the tip is worked out
The maths is a single percentage of the bill. The tip is
bill x (tip% / 100), the total is bill + tip, and if you are
splitting, each share is total / people. On a 60 dollar bill at 18% the tip is
10.80, the total is 70.80, and split between two that is 35.40 each. This calculator rounds
each figure to the nearest penny and never touches a server, so it works offline too.
How much should you tip?
Tipping norms vary a lot by country and by service. As a rough guide:
- US restaurants - 15% is the floor, 18% to 20% is normal, more for exceptional service.
- UK and Europe - 10% to 12.5%, and often already added as a service charge.
- Cafes and takeaway - rounding up or dropping loose change is plenty.
- Bars - a small amount per drink, or 10% on a tab.
If a service charge is already printed on the bill you generally do not need to add more. When a menu says "service not included", the percentage buttons above cover the usual range.
Tip amounts at a glance
For a quick sense of the numbers before you reach for the calculator, here is what the common percentages come to on a few round bills:
| Bill | 15% | 18% | 20% |
|---|---|---|---|
| 20.00 | 3.00 | 3.60 | 4.00 |
| 50.00 | 7.50 | 9.00 | 10.00 |
| 80.00 | 12.00 | 14.40 | 16.00 |
| 120.00 | 18.00 | 21.60 | 24.00 |
A quick mental shortcut
To sanity-check the number without a phone, find 10% by shifting the decimal one place to the left, then scale it. 10% of 84 is 8.40, so 20% is 16.80 and 15% sits halfway at 12.60. If you tip in cash but pay the bill by card, remember to base the tip on the pre-service-charge figure so you are not tipping twice. That trick is just the percentage calculation done in your head. Splitting an awkward total? The discount calculator and VAT calculator use the same one-line percentage maths.
