How to calculate a tip
A tip is a percentage of the bill, so the maths is simple: multiply the bill by the tip rate divided by 100. An 18% tip on an $80 bill is 80 × 0.18 = $14.40, making the total $94.40. This calculator does that instantly and then splits the total across however many people are paying, so nobody has to do percentages at the table. Adjust the tip percentage to match the service and your local custom, and the tip, total and per-person figures update together.
How much should you tip
Tipping norms vary widely by country and setting. In the United States, 15–20% is standard for restaurant table service, with 18% a common default and more for exceptional service. Many European countries include service in the bill and a small round-up is enough, while in some countries tipping is not customary at all. For cafés, bars, taxis and delivery, expectations differ again. Use the percentage field to match the situation rather than assuming one number fits everywhere — the calculator makes any rate effortless.
Tipping on the pre-tax or post-tax total
A common question is whether to tip on the bill before or after sales tax. Etiquette generally says the tip is for the service, so calculating it on the pre-tax subtotal is perfectly reasonable, though many people simply tip on the total for convenience. The difference is usually small. If you want to tip on the pre-tax amount, enter that subtotal as the bill here; if you prefer to tip on the full total, enter the post-tax figure. Either way the split stays accurate.
Splitting the bill fairly
Dividing the total equally is the quickest way to settle a shared meal, and this calculator shows both the per-person total and each person's share of the tip. For an uneven split — where people ordered very differently — a flat percentage tip still works: apply the tip to the whole bill, then have each person add the same tip percentage to what they personally ordered. Rounding each share up slightly is a friendly way to ensure the tip is never short.
