What the bill splitter is for
Eating out with a group is the easy part; the awkward moment is the bill. How much does everyone owe? Do we add a tip? Who has change? This calculator clears it up: type the total bill, how many people are sharing and the tip you want to leave, and it instantly shows what each person pays in equal shares. That equal split is the whole point, and it is what sets this apart from a plain tip calculator: the focus here is the fair share across N diners.

How to use the calculator
- Total bill: the amount on the check as-is, before any tip.
- Number of people: how many are sharing. Leave it blank if you don’t know yet and the result shows a dash.
- Tip (%): tap a quick button (0, 10, 15, 18 or 20%) or type any other percentage in the “Other” field.
- Round each share up: tick the box so each person pays a clean figure with no awkward cents. The group chips in a little more, and that difference appears under “The group chips in”.
On screen you’ll see each person’s share (in large type), plus the tip, the total with tip, and how much the group pays together.
How it is calculated
The method is an equal split over the tipped total. With bill B, tip percentage p and n people:
- Tip =
B × p / 100 - Total with tip =
B + tip - Each person =
Total with tip / n
When rounding is on, each share is rounded up to the next whole number with ceil(Total / n), and “The group chips in” becomes that share times n, almost always a touch above the exact total.
| Bill 1500 with 15% tip (total 1725) | Each person pays |
|---|---|
| Between 2 | 862.50 |
| Between 3 | 575.00 |
| Between 4 | 431.25 |
| Between 5 | 345.00 |
| Between 6 | 287.50 |
Worked example
A bill of 1000, a 15% tip, split among 4 people:
- Tip: 1000 × 15 / 100 = 150
- Total with tip: 1000 + 150 = 1150
- Each person pays: 1150 / 4 = 287.50
Now a case with messy decimals: a bill of 1200 at 18% among 5 people. The tip is 216, the total is 1416, and each share would be 283.20. Turn on rounding and each person pays 284, so the group chips in 284 × 5 = 1420, which is 4 more than the exact total.
Frequently asked questions
How is this different from a tip calculator?
A tip calculator focuses on how much to leave for service. This tool goes one step further and prioritizes the split: what each diner owes when you divide equally, with or without a tip, and with an option to round up so nobody juggles loose coins.
What if everyone ordered different things?
An equal split is most practical when everyone spent about the same. If someone ordered far more, the fair move is to add up each person’s items separately and apply the same tip percentage to each subtotal. This calculator divides the total evenly, so use it when the group agrees to pay the same.
Why does the group pay more when I round up?
Because rounding up pushes each person’s share to the next whole number. If the exact split was 283.20 and each person pays 284, those extra 0.80 per person add up: across 5 people that’s 4 more. It’s handy for paying without cents, and the surplus usually becomes an extra tip.
Is the tip figured before or after tax?
It depends on local custom. In many places the tip is calculated on the total including tax; another school applies it only to the subtotal. The calculator uses whatever amount you enter as the bill, so you decide which base the percentage applies to.
Can I set the tip to 0%?
Yes. Tap the 0% button (or type 0 in “Other”) and the tool simply splits the bill among the people with nothing extra added.
