Split the bill and tip without the awkward maths
Working out a tip in your head while the card machine waits is a small but reliably stressful moment. This calculator removes the guesswork: type the bill, tap a tip percentage, say how many people are sharing, and it shows the tip, the grand total and exactly what each person owes — updating live as you type. Pick US dollars, British pounds or euros and every figure is formatted with the right symbol and grouping.
How the maths works
The whole calculation is four short steps:
- Tip:
tip = bill × percent ÷ 100 - Total:
total = bill + tip - Per person:
perPerson = total ÷ people - Tip per person:
tipPerPerson = tip ÷ people
Every result is rounded to two decimal places for display, and the number of people is always treated as at least one so the division never breaks.
A worked example
Suppose dinner comes to $84.50, you want to leave a 20% tip,
and four of you are splitting it. The tip is 84.50 × 20 ÷ 100 = $16.90. The total is
84.50 + 16.90 = $101.40. Divided four ways that is 101.40 ÷ 4 = $25.35
each, of which 16.90 ÷ 4 = $4.23 (rounded) is the tip. Done before the waiter is
back.
Typical tipping by service
| Situation | Common range | Note |
|---|---|---|
| Sit-down restaurant | 15–20% | 20% for good service is increasingly standard in the US. |
| Bar (per drink or tab) | 10–20% | Often a flat amount per drink for simple orders. |
| Food delivery | 10–15% | A little more in bad weather or for a large order. |
| Counter / takeaway | 0–10% | Optional; tip jars are a courtesy, not an expectation. |
| Taxi / rideshare | 10–15% | Rounding up to the next note is also common. |
These are common US conventions for reference only. Tipping norms differ greatly between countries — in some, service is included and tipping is minimal or unusual.
