Tip Calculator

Figure out the tip and the total at a restaurant, bar, or any service, and split the bill cleanly across any number of people. Set the row to Increase, enter the bill total and the tip percentage; the total to pay appears immediately. Then pick a group size below to see what each person owes.

How a tip is calculated

A tip is a percentage increase on top of the bill. The formula is total = bill × (1 + tip ÷ 100). The tip itself is bill × tip ÷ 100; the total is the bill plus that tip.

The calculator below uses the Increase / Decrease by mode set to Increase, so the result is the full amount you'll pay, tip included. Customary tip rates vary by country and service type: 15-20% in the US for sit-down restaurants, 10-15% in much of Europe (where service is sometimes already included), and not customary at all in Japan or South Korea.

Worked example

Dinner is $50 and you want to leave 18%. Set the toggle to Increase, enter 50 as the base, 18 as the percentage. The result is 59, the total. The tip itself is $9. Split between 3 people, that's $19.67 each.

Tip Calculator FAQ

What's a standard tip percentage?
In the US: 15-20% at sit-down restaurants, 10% at counter service, 18-20% for delivery, 15-20% in taxis/rideshare. In the UK and most of Europe: 10-15%, often only when service hasn't been added to the bill. Norms vary by country; check the local convention if you're traveling.
What's an 18% tip on $50?
$9 in tip, $59 total. Multiply 50 by 0.18 for the tip; add it back to the bill for the total. The calculator above does both in one step.
Tip on the pre-tax or post-tax amount?
Either is reasonable. Pre-tax is the more traditional convention (you're tipping for service, not on the government's cut). Post-tax is simpler if you only have the final total in front of you. The numerical difference is small at typical tax rates.
How do I split the bill evenly?
Use the "Split between N people" input below the calculator. It divides the post-tip total evenly. For uneven splits (everyone pays for what they ordered), you'd compute each person's share separately and add proportional tip.
Cash or card: does it matter?
Functionally no, but cash tips are paid out faster and don't get taxed at source in some jurisdictions. Some servers prefer cash for that reason. Either is acceptable.
