How to use
How this bill split calculator works
This bill split calculator divides a restaurant check, a group gift, a vacation rental or any shared expense into fair shares. Enter the total, the number of people and, if anyone is not paying, how many. You get each person’s share, a short bar chart of who pays what and a ready-made payment note you can paste into a group chat. Because a total rarely divides into exact cents, you choose how to handle the leftover: everyone rounds up a little, or one person (the organizer) covers the remainder. You can also pick how finely to round, from the nearest cent up to the nearest $5.
The math in plain words
The tool first works out how many people are paying: everyone minus those who are not. The exact share is the total divided by that number. Then it applies your rounding choice:
- Round up evenly. Each share is rounded up to your chosen unit, so everyone pays the same and the group collects slightly more than the bill. The extra goes to whoever collects the money. For $100 split three ways, the exact share is $33.333, so each person pays $33.34, the group collects $100.02 and $0.02 is left over.
- Organizer covers the remainder. Everyone else pays a rounded-down share and the organizer pays whatever is left. For the same bill, two people pay $33.33 and the organizer pays $33.34, so the total is exactly $100.00.
Rounding to the nearest $1 is handy when people pay in cash: $100 split three ways becomes $34 each, with $2 extra for the person who handles the payment. When some people leave early or did not eat, enter them under “People not paying.” A $180 total with six people and one not paying is $180 ÷ 5 = $36 each.
Include tax and tip in the total
In the United States the number printed on a check usually leaves out the tip, so add it before you split. The bill total field expects the full amount you want to cover. At a sit-down restaurant, a tip of 15% to 20% of the pre-tax food and drink total is common, and many people go to 20% or more for good service. Some restaurants add an automatic gratuity for large parties, often six or more guests, so look at the check before adding more. For example, a $200 meal before tax plus 20% tip ($40) and $16 of sales tax comes to $256. Entered with four people, that is $64 each. Sales tax rates differ by state and city, so use the figure on your receipt rather than a guess.
When an equal split is fair and when it is not
Splitting evenly is quick and keeps the mood friendly, and it works well when everyone ordered something similar. It is less fair when one person had an expensive entrée or several drinks while another had a salad and water. In that case, split by item: add each person’s items, then add their share of tax and tip in proportion. You can still use this tool for the shared parts, such as appetizers or the tip, by entering that amount as the total. Many groups agree on a simple rule in advance, such as splitting evenly unless someone had a clearly smaller meal.
Sending and collecting the money
- Pick one person to pay the check with their card, then collect from everyone else through a payment app such as Venmo, Zelle, Cash App or Apple Cash. This avoids a long line of card swipes.
- Copy the payment note. The note lists the amount each person should send, the total and the number of people, so there is no confusion in the chat.
- Use the share link. The link stores your numbers in the web address so you can send the same setup to someone else or reopen it later.
- Decide who gets the extra cents. With “Round up evenly,” the leftover covers small fees or goes to the organizer for the trouble.
Other things you can split
The same math works for a shared Airbnb or hotel room, a gas and snack budget on a road trip, a group gift, utilities in a shared apartment or a catered office lunch. For recurring costs such as rent and utilities, many roommates split by room size or income instead of evenly, so agree on the rule once and then enter each person’s share as a separate calculation if needed.
A quick example for a group dinner
Five friends share a dinner. The check is $187.45 before tip, and they agree on a 20% tip of $37.49, so the total is $224.94. Entered with five people and the nearest-cent setting, each person owes $44.99, the group collects $224.95 and one cent is left over. If the friend paying the check prefers the exact total, switching to “Organizer covers the remainder” makes four people pay $44.98 and the organizer pays $45.02, which lands exactly on $224.94.
Frequently asked questions
How do I split a bill evenly?
Divide the total by the number of people paying. If you also want to include a tip, add it to the total first. This calculator then rounds each share to the unit you choose and shows what everyone sends and how much is left over.
Should the tip be calculated before or after tax?
Either is acceptable. Many people tip on the pre-tax amount because tax is not a service charge, while others tip on the full total for simplicity. A common range is 15% to 20% at a sit-down restaurant. Check your receipt, because some places add an automatic gratuity for large groups.
What if someone did not eat or left early?
Enter how many people are not paying in the “People not paying” field. The calculator divides the total among the remaining payers. If the people who left should still contribute to the tip or shared dishes, include them in the headcount instead.
What does “organizer covers the remainder” mean?
Everyone but one person pays a rounded-down share, and the organizer pays whatever is left so the total matches the bill exactly. It is a good option when you do not want to collect more money than the bill.
Why does the group collect slightly more than the total?
When the total does not divide into exact cents, rounding every share up to the same amount creates a small surplus. With the nearest-cent setting the extra is at most a few cents. If you choose $1 or $5 rounding the surplus can be larger, and it belongs to whoever collects the money.
Can I split unevenly or by item?
This tool is built for equal shares. For uneven splits, work out each person’s items plus a proportional share of tax and tip, or run the calculator separately for the shared items and for each person’s own items.
