Split Bill Calculator

How to split a bill

1. Pick By item for a meal where people had different things, Evenly for a straight split, or By income for rent and household bills.
2. Type the names. Empty names are called Person 1, Person 2 and so on.
3. By item: add each line of the receipt with its price and tap the names of everyone who had it. Shared dishes are split evenly among those people, or by weights under Custom shares.
4. Add tax, tip, a discount or a service charge, each as a percentage or an amount, and choose whether the tip is worked out before or after tax.
5. Read each person's total on the right (below on a phone). Tap Copy summary to paste it into the group chat, or Share link to send the whole bill so others can check it.

How the shares are worked out

By item, each person's subtotal is the price of what they had, with a shared item split between the people ticked for it (or by their weights). The discount comes off the items subtotal; the service charge and the tax are percentages of the subtotal after the discount; the tip is a percentage of that same amount (before tax) or of the amount after service and tax. Each of these is shared in proportion to the subtotals, so everyone pays the same rate on what they ordered.

Worked example: Ana had 30.00, Ben 20.00 and all three shared a 45.00 platter (15.00 each). Subtotals 45.00, 35.00, 15.00; 95.00 in all. Tax at 8% is 7.60 and an 18% tip before tax is 17.10, so the bill is 119.70 and every subtotal is multiplied by 119.70 / 95.00 = 1.26: Ana 56.70, Ben 44.10, Cleo 18.90. With a 10% discount every share drops by exactly 10%, to 51.03, 39.69 and 17.01.

Rounding. Money only comes in whole cents (or whole yen, or thousandths of a dinar), so a fair share is usually not a payable amount: 100.00 among three is 33.333… each. The calculator uses largest-remainder rounding: everyone is rounded down, and the cents left over go one each to the shares that lost the most, earlier names first when they tie. So 100.00 becomes 33.34 + 33.33 + 33.33, the shares always add up to the bill, nobody pays more than one unit above their exact share, and the page says who pays the extra cent. Each column (items, tax, tip) is rounded the same way, and the last of them takes up any leftover cent so every row adds up to its total.

Currencies. The number of decimals comes from the ISO 4217 table (2 for the dollar, euro and pound, 0 for the yen and Korean won, 3 for the Kuwaiti and Bahraini dinar). The table here is ISO 4217 List One as published by SIX Group, the ISO 4217 maintenance agency (list dated 2026-09-17), fetched on 2026-10-18 from six-group.com.

What it cannot do

• It does not send money or payment requests to anyone. It works out the amounts; you settle up with cash or your own payment app.
• It does not read a photo of the receipt. Every item and price is typed by you.
• Tax rules are what you type, not looked up. It does not know any country's or state's rates, whether tips or service charges are taxed where you are, or prices that already include VAT (then leave tax empty).
• One discount, one service charge and one tax rate for the whole bill. A discount on a single dish is best typed as a lower price for that item.
• No currency conversion: the whole bill is in one currency.
• Up to 30 people and 100 items. Share links longer than 2,000 characters (a long receipt) may be cut short by some chat apps.

Privacy and what is stored

Names and amounts never leave your device. The bill is saved in this browser's local storage as you type, so a reload does not lose it; Clear saved bill deletes it in one tap. The page sends an anonymous page-view count and, at most, two fixed words (split-calc, split-share-open); never a name or a number. A share link carries the bill after the #, which browsers do not send to any server, and opening one saves nothing unless you tap Keep this copy.

Questions

How do I split a bill with tax and tip?

Add each person and each item with its price, tick who had it, then type the tax and the tip as a percentage or an amount. Tax and tip are shared in proportion to what each person ordered, so someone whose food cost twice as much pays twice the tax and twice the tip. Example: 30.00 for Ana, 20.00 for Ben and a 45.00 platter for all three, with 8% tax and an 18% tip on the pre-tax total, comes to 119.70: Ana 56.70, Ben 44.10, Cleo 18.90.

How do I split a restaurant bill when people ordered different things?

Use By item. Type every line on the receipt and tap the names of the people who shared it. A bottle shared by two is split between those two only; a starter for the table is split among everyone. If one person had more of a shared dish, switch the item to Custom shares and give them a weight of 2 against 1 for the others.

How do I split a bill based on income?

Use By income, type the bill and each person's income. Each pays the bill times their income divided by the total income: on a 1,500 rent with incomes of 3,000 and 2,000, the first pays 900 and the second 600. Use the same period (monthly, or yearly) for every income; before or after tax is your choice, as long as it is the same for everyone. You can type percentages instead, such as 60 and 40.

How is a discount split?

A discount (a voucher, a percentage off, a happy-hour deal on the whole bill) is taken off the items subtotal and shared in proportion to each person's items, so everyone saves the same percentage. Tax, service charge and a pre-tax tip are then worked out on the discounted subtotal. If a discount applied to one person's dish only, lower that item's price instead.

How should couples split bills?

Couples usually pick one of three: 50/50 (Evenly, 2 people), in proportion to income (By income, so both spend the same share of what they earn), or by what each used (By item). The calculator does all three on the same numbers, so you can compare before you agree. It does not move money; you settle up however you normally do.
