How to split a restaurant bill fairly, including tips

1. Agree on the split before doing the maths

There are two useful starting points. An equal split works when everyone ordered roughly the same amount and everyone agrees. An itemised split works when orders differ, some people skip alcohol or only part of the group shares a dish. Neither approach is automatically fair for every table.

Keep the conversation small: “Shall we each cover our own food, then split the sides?” That is enough to establish the rule. Decide whether a birthday meal is a gift before adding the birthday person's share to everyone else's.

• Equal: divide the complete payable total by the participating diners.
• By item: add each person's items and their portion of shared dishes, then allocate additional charges.
• A mixture: share the food equally but assign individual drinks to the people who ordered them.

The person paying the restaurant is the payer, not automatically the person responsible for every item. Keep “who paid” separate from “who owes what”.

2. Check the receipt and the amount actually paid

Check the receipt's currency, line totals, missing items and duplicate lines before splitting. If a line says “2 × coffee, £7.00”, establish whether £7.00 is the combined line total. Do not multiply a total by its quantity a second time.

Then check what is already included. A tax figure printed for information is different from a tax amount added to the subtotal. The same applies to service: VisitBritain notes that some restaurants add a service charge to the bill. Read the receipt before adding another amount.

Use the amount that was actually paid, with any agreed additional tip. If the restaurant corrected a charge, use the corrected receipt. Receipt scanning helps enter the bill; reviewing the result is still part of the job. In Divisa's receipt workflow, you check extracted items before assigning them to people.

3. Assign items and divide the shared dishes

Here is our worked example, with four fictional diners. You order £24 of individual items, Mia orders £18, Théo £22 and Sam £16. Everyone shares £16 of sides, so each person adds £4. The item subtotal is £96.

The receipt adds a £12 service charge, equal to 12.5% of the item subtotal. For this example, the group agrees to allocate it in proportion to each person's item share. There is no further tax to add and no additional tip.

Your service share is £28 ÷ £96 × £12 = £3.50. Apply the same calculation to each person. An equal division would instead be £27 each; it produces the same total but distributes the cost differently.

If Sam had not eaten the sides, their £16 cost would be shared among the other three diners. Change the participants on that item, rather than removing Sam from the whole bill.

4. Allocate extra charges and account for the last penny

For a proportional allocation, the general calculation is: person's item share ÷ item subtotal × additional charge. This gives a smaller service or tip share to someone with a smaller order. A group can agree on a different arrangement, but make that choice explicit.

Divisa allocates bill-level tax, service and tip amounts in proportion to assigned item value. Check those amounts during receipt review, and enter an additional tip only once. This is a way of dividing the agreed bill, not a rule about how much a restaurant must charge.

Some divisions cannot be paid exactly. A £18.50 dish shared equally by three people is £6.1666… each. One valid allocation is £6.17, £6.17 and £6.16, which totals £18.50. Rounding all three shares up would collect £18.51.

Keep a consistent rule for distributing leftover pennies and check the final total. Divisa handles the split and rounding; you do not need to add a mystery “rounding fee” to recover a missing penny.

5. Repay the person who covered the bill

If you paid the full £108 in our example, your own £31.50 share is already covered. Mia pays you £24.75, Théo £29.25 and Sam £22.50. Those repayments total £76.50; together with your £31.50 share, they account for the full receipt.

Confirm the recipient, amount and currency before sending. Divisa can open supported payment links or provide saved details to copy into a payment app. Payment support depends on the method and currency; saving a split does not transfer any money.

Mark the repayment paid after it has been made. If the table already paid the restaurant separately, do not also reimburse one person for the entire bill. For a holiday where different people cover different meals, settling the trip's overall balance can be simpler than repaying every receipt individually.

When diners use different currencies, keep the original receipt currency and follow the settlement amount shown for the recipient. Our multi-currency bill guide explains that distinction with a euro and pound example.
