Bill Splitter
Split an itemized bill with tax and tip. Shares add up to the cent.
| Subtotal | |
| Tax | |
| Service charge | |
| Tip | |
| Total |
How It Works
Add everyone at the table, then each item with its price. Tick the people who had each item; a shared item is split equally among the people ticked. Enter the tax and any service charge from the receipt (as an amount or a percentage of the subtotal) and the tip percentage you want.
Each person pays for their items plus the same fraction of the tax, service charge and tip as their fraction of the subtotal. Someone whose items make up 40% of the subtotal pays 40% of each extra. That's fairer than an even split when one person had a salad and another had steak and wine.
Rounding to the Cent
Exact shares often end in fractions of a cent. Rounding each one to the nearest cent can leave the group a cent or two short of the bill, or over it. This calculator uses the largest-remainder method instead:
- Work out every person's exact share of the total.
- Round each share down to the cent.
- Hand out the cents still missing, one each, to the people whose shares lost the most in rounding down. Ties go to whoever is listed first.
The shares then add up to the bill total exactly, and nobody pays more than a cent above their exact share. The breakdown inside each card (items, tax, service, tip) is rounded for display; any difference from the amount to pay is shown as a rounding line.
Tip Before or After Tax?
The Tip on setting chooses the base for the tip percentage. Pre-tax subtotal tips on the items only. Subtotal + tax tips on the items plus tax, which comes out a little higher. Either way the service charge is not included in the tip base. If the receipt already adds a service charge or automatic gratuity, check whether you still want to tip on top.

Frequently Asked Questions
How do I split a bill with tax and tip by what each person ordered?
Add up what each person ordered, sharing any shared dish equally among the people who had it. Then give each person the same fraction of the tax and tip as their fraction of the food. Someone who ordered 40% of the subtotal pays 40% of the tax and 40% of the tip. This calculator does that for you.
Should the tip be calculated before or after tax?
It is your choice, and this calculator offers both. Tipping on the pre-tax subtotal tips on the food and drink only. Tipping on the post-tax amount gives a slightly larger tip. On a 60.00 subtotal with 5.33 tax, an 18% tip is 10.80 pre-tax or 11.76 post-tax.
Why do the shares not divide evenly to the cent?
Because money only comes in whole cents. 100.00 split three ways is 33.333... each. This calculator rounds each share down to the cent, then gives the leftover cents one at a time to the people whose shares were rounded down the most, so the shares always add up to the exact bill total. If two people tie, the cent goes to whoever is listed first.
How do I split a shared item?
Tick everyone who shared it. The item's price is divided equally among the people ticked, so a 30.00 dish shared by three people adds 10.00 to each of their subtotals.
What if the receipt already includes a service charge or gratuity?
Enter it as a service charge and set the tip to 0, or you may end up tipping twice. The service charge is shared in proportion to each person's items, like tax.
