Bill Split Calculator — Split Bills & Tip Evenly
Enter the bill amount, tip percentage, and number of diners to instantly see how much each person owes. Switch to unequal split mode to assign custom percentages when orders vary. Handles rounding so every cent is accounted for.
Enter the bill amount to calculate the split.
How it works
How to split a restaurant bill fairly
The easiest approach is to divide the total (bill + tip) by the number of diners. This works well when everyone ordered roughly the same value — shared appetizers, similar entrees, one drink each. Most modern card terminals can handle multiple payments, so each person can tap their card for their calculated share.
If the bill comes to a number that doesn't divide evenly, the calculator distributes the extra cents to the first person or two in the group — a difference of a penny or two that nobody will notice. The important thing is that the sum of all individual shares equals the exact total, so the restaurant gets paid in full.
For larger groups at catered events or private dining rooms, ask about the house policy upfront. Many venues add an automatic 18-20% service charge for parties of six or more. In that case, an additional tip is optional and you can set this calculator's tip percentage to zero and just divide the final bill total.
Tipping customs around the world
Tipping culture varies enormously. In the United States and Canada, 18-22% is the social norm at sit-down restaurants, and leaving nothing implies serious dissatisfaction rather than cultural indifference. In the United Kingdom and Australia, 10-15% is appreciated but often folded into an optional service charge. In much of continental Europe — France, Germany, Italy — rounding up or leaving a few coins is standard; percentages are rarely calculated.
In Japan, South Korea, and China, tipping is traditionally not expected and can occasionally cause awkwardness at formal establishments. Staff may try to return the money. In these contexts, leaving a tip in a country card machine or app may simply be processed as an anonymous donation. When traveling, a quick search for local tipping customs is worth the 30 seconds it takes.
In Brazil and Mexico, a 10% service charge is often included by default; check the bill before adding more. In the Middle East and parts of Southeast Asia, 10% is a common expectation at tourist-facing restaurants. This calculator lets you set any tip percentage from 0 to 30%, so you can match local norms wherever you are.
When to split unevenly
Even splits break down when orders diverge significantly. If one person had a $12 pasta and another had a $55 steak, splitting the total down the middle doesn't feel fair. The same logic applies when dietary restrictions meant someone skipped alcohol, or when one guest arrived late and only had dessert. In these cases, switching to custom split mode lets everyone assign a percentage that reflects what they actually ordered.
Another common scenario is when someone picks up a round of drinks or pays for a shared dessert outside the main bill. You can handle this by reducing that person's share percentage to reflect what they already contributed. The calculator shows a running total of assigned percentages and flags when the shares don't add up to 100%, so nothing falls through the cracks.
Some groups have a standing rule: the person who earns more covers more, regardless of who ordered what. This is especially common among close friends or family. Custom split mode accommodates this too — just enter the agreed percentages and let the calculator do the arithmetic. There's no single right answer; the right split is whatever the group agrees feels fair.
Frequently asked questions
›How do I split a bill with different orders?
Switch to Custom split mode. Add each person's name (optional) and enter the percentage of the bill they should cover. The calculator validates that all shares add up to 100% before showing amounts.
›Does the calculator include tax?
It does not add tax automatically because tax rates vary widely by location. Enter the bill amount that already includes any sales tax, or enter the pre-tax subtotal if you prefer to tip on that figure.
›What happens when the total doesn't divide evenly?
The calculator distributes remaining cents to the first one or two people in the split. The rounding note below the results shows exactly how many extra cents were added and to whom, so the total always matches.
›Can I use this for Venmo or payment app requests?
Yes. Each person's amount in the results is the exact figure to request. For custom splits, the table shows each person's share to the cent.
›What tip percentage should I use?
In the US and Canada, 18-20% is the current norm for sit-down restaurants; 15% is acceptable for counter service or to-go orders. In the UK and Australia, 10-15% is typical. In Japan and much of Asia, 0% is perfectly appropriate.
›How do I handle a large party with an automatic gratuity?
If the restaurant already added a service charge, set the tip percentage to 0% and enter the final bill total (including the service charge). Then divide by the number of guests for the even-split amount.
›Is the currency in dollars?
The calculator displays USD by default and JPY on the Japanese locale. The math is currency-neutral — the same percentage and division logic applies to any currency.
›Can I save or share the calculation?
The page URL does not encode state, so to share results take a screenshot or note down the amounts. A shareable link feature may be added in a future update.
