Calculate tip and split the bill instantly for any group size.
Calculating a tip is straightforward once you know the formula. Multiply your bill amount by the tip percentage expressed as a decimal. For example, a 20% tip on a $85 dinner bill works out as: $85 × 0.20 = $17 tip, making your total $102. Our tip calculator does this instantly so you never have to do the math in your head at the table.
Tipping customs vary by country and service type, but here are the widely accepted standards in the United States. At sit-down restaurants, 15% is considered the minimum for adequate service, 18–20% is standard for good service, and 25% or more is appropriate for exceptional service. For food delivery drivers, tip between 15–20% of the order total, with a minimum of $3–5 regardless of order size since drivers cover their own fuel costs. Rideshare and taxi drivers typically receive 15–20%, and hotel housekeeping staff are usually tipped $2–5 per night, left daily rather than at checkout since different staff may clean your room each day.
This is a genuinely debated question. Technically, tipping on the pre-tax amount is more logical since your server did not provide the tax — they provided the service. However, tipping on the post-tax total is increasingly common and the difference on a typical restaurant bill is small. On a $100 pre-tax bill with 10% tax, tipping 20% on pre-tax gives $20 while tipping on post-tax gives $22 — a $2 difference. Most people tip on the total bill for simplicity.
Splitting bills evenly is the simplest approach — enter the total and number of people and our calculator divides everything equally including the tip. However, equal splits can feel unfair when people ordered very different amounts. In those cases, each person can calculate their share individually by entering their own subtotal and the agreed tip percentage. For large groups, many restaurants add a mandatory gratuity of 18–20% automatically, so always check your bill before tipping extra.
Tipping norms vary dramatically by country. In the United States and Canada, tipping is essentially expected and service workers often rely on tips as a significant portion of their income. In Australia and New Zealand, tipping is appreciated but not mandatory. In Japan and South Korea, tipping can actually be considered rude or insulting in some contexts, as good service is considered standard. In the United Kingdom and most of Europe, 10–15% is appreciated at restaurants but not always expected. If you are travelling internationally, it is worth researching local customs before dining out.
While tipping is generally expected in service industries, there are situations where it is reasonable to tip less or nothing. Genuinely poor service — rude behaviour, long unexplained waits, or mistakes that were not corrected — is a valid reason to reduce a tip. However, it is worth distinguishing between poor service from your waiter versus kitchen delays or issues outside their control. Fast food and quick service restaurants where you order at a counter have no traditional tipping expectation, though digital payment terminals increasingly prompt for tips in these settings.
