Tip Calculator
Splitting a restaurant check is the most common place people do percentage math under pressure, and it is easy to fumble at the table. This tip calculator takes the bill, the tip percentage, and the number of people, then shows the tip, the grand total, and exactly what each person owes. Because it folds the split into the same page, there is nothing to add up afterward — read the per-person figure and you are done, whether you are at a restaurant, a bar tab, a salon, or a food delivery.

How to calculate
Enter the bill amount, choose a tip percentage, and set how many people are sharing the cost. The calculator multiplies the bill by the tip rate to get the tip, adds it to the bill for the total, then divides that total by the number of people. For a $100 bill at 20% across four people, the tip is $20, the total is $120, and each person pays $30. Adjust any field and the figures update instantly, so you can compare a 15%, 18%, and 20% tip before deciding.
tip = bill × (tip% ÷ 100), then total = bill + tip, and per person = total ÷ number of people. The tip is calculated on the bill amount you enter — if you prefer to tip on the pre-tax subtotal, enter that figure rather than the taxed total.
Example calculation
A $100 bill with a 20% tip adds $20, for a grand total of $120. Split four ways, that is $30 per person. The tip is taken on the pre-tax bill amount entered above.

Assumptions
- The tip is calculated on the bill amount you enter; whether that includes tax is your choice, since tipping conventions on tax vary.
- The total is divided evenly across everyone — the calculator does not handle uneven shares or splitting only part of the table.
- Tipping norms differ by country and service type; the percentage is yours to set, not a recommendation.
Common mistakes
- Tipping on the post-tax total when you meant to tip on the pre-tax subtotal, which slightly overpays the server's share.
- Rounding the per-person amount down so the pooled cash falls short of the actual total.
- Forgetting that a service charge already on the bill may be a tip, leading to double-tipping.
