How to split a bill between friends
Equal splitting is fast, itemising is fair, and the right answer depends on how different the orders were.
Short answer
Split the bill equally if everyone's order was roughly similar; if one item was much bigger than the rest, pull it out, split the remaining food equally, and add tax and tip in proportion to what each person actually ordered.

- 1If the orders were similar, split equally and stop there.
- 2If one or two items were much larger, pull those out and split the rest equally.
- 3Add the tip proportionally rather than per head if you itemised.
- 4One person pays, everyone transfers immediately — do not let it sit.
A restaurant bill is the smallest, most common version of this problem, and it's the one people get wrong most often — usually by either forcing an unfair equal split on a very unequal bill, or spending ten minutes itemising a bill that barely needed it.
The decision that matters is how different the orders were. Below roughly a 20% gap between the cheapest and most expensive order, equal splitting is faster and nobody feels shortchanged. Above that, pull out only the genuine outlier — not every difference of a starter or a drink.
Tax and tip should follow whichever method you used for the food: if you split the food equally, add tax and tip per head too; if you itemised, add tax and tip as a percentage of each person's own items, so someone who ordered less doesn't subsidise someone else's tip.
Worked examples with real numbers
One expensive order, itemised with tax and tip
Five friends eat out. Food comes to 150 — Leo's steak and lobster alone is 45, the other four total 105. Tax is 8% and tip is 20%, both on the food subtotal, making the bill 192. Noah pays on card.
| Items before tax and tip | Amount |
|---|---|
| Leo | 45.00 |
| Mia | 25.00 |
| Noah | 30.00 |
| Owen | 20.00 |
| Priti | 30.00 |
| Person | Paid | Fair share | Balance |
|---|---|---|---|
| Leo | 0.00 | 57.60 | −57.60 |
| Mia | 0.00 | 32.00 | −32.00 |
| Noah | 192.00 | 38.40 | +153.60 |
| Owen | 0.00 | 25.60 | −25.60 |
| Priti | 0.00 | 38.40 | −38.40 |
- LeoNoah57.60
- PritiNoah38.40
- MiaNoah32.00
- OwenNoah25.60
Tax plus tip add 28% on top of every item (12 + 30 = 42, on 150 of food). Multiply each person's item cost by 1.28 and that's their full share — Leo's 45 steak becomes 57.60 once tax and tip are included, everyone else's scales the same way.
A shared starter, unequal mains, and a drink not everyone had
Anaya, Beth, Cai and Dax split a 132 bill: a 20 starter shared by all four, mains that differ (18, 22, 18, 24), and a 30 bottle of wine split only between Beth and Dax, who drank it. Cai pays the bill.
| How the total splits | Amount |
|---|---|
| Shared starter (÷4) | 20.00 |
| Mains (individual) | 82.00 |
| Wine (Beth & Dax only) | 30.00 |
| Total | 132.00 |
| Person | Paid | Fair share | Balance |
|---|---|---|---|
| Anaya | 0.00 | 23.00 | −23.00 |
| Beth | 0.00 | 42.00 | −42.00 |
| Cai | 132.00 | 23.00 | +109.00 |
| Dax | 0.00 | 44.00 | −44.00 |
- AnayaCai23.00
- BethCai42.00
- DaxCai44.00
The starter is split four ways at 5 each, mains are exactly what each person ordered, and the wine is split two ways at 15 each — only among the people who drank it. Three transfers to the person who paid clears it.
Splitting a single bill with tax and tip
1. 1. Separate shared items from individual ones
starters/shared plates vs mains ordered per person
2. 2. Split shared items equally
shared total ÷ number sharing it
3. 3. Add each person's individual items
their share of shared items + their own items
4. 4. Apply tax and tip proportionally
person's total × (1 + tax rate + tip rate)
5. 5. Compare to what was actually paid
balance = paid − full share (with tax and tip)
Ways to split a restaurant bill
| Approach | Best when | Handles tip/tax | Speed |
|---|---|---|---|
| Equal split | Orders were broadly similar | Add per head | Fastest |
| Pull out one outlier | One item much bigger than the rest | Add per head on the rest, proportionally on the outlier | Fast |
| Full itemising | Orders varied a lot across the table | Proportional to each person's items | Slower, most exact |
| One person pays, others transfer | Any of the above, once shares are known | Doesn't change the maths, just who's owed | Instant to settle |
Mistakes that cause arguments
Splitting tax and tip equally on an itemised bill
If you've itemised the food, keep going — tax and tip should scale with what each person ordered, or the person who had less ends up subsidising someone else's tip.
Itemising over a small gap
A 20% difference in orders isn't worth the time cost of itemising. Split equally and move on.
Forgetting shared starters when itemising mains
A shared plate still needs splitting even if the mains are individual — don't fold it silently into one person's total.
Rounding badly on the tip
Round the total tip once, not each person's tip separately — separate roundings can leave the tip short by a few units.
Practical tips
- Ask upfront whether anyone wants to itemise before ordering, not after the bill arrives.
- Only pull out items that are meaningfully bigger — not a slightly pricier starter.
- Keep tax and tip proportional to whichever split method you used for the food.
- Have one person pay the full bill on a card and collect transfers — it's simpler than everyone paying separately.
- Settle immediately at the table if you can; delayed restaurant splits are the ones that get forgotten.
Questions
- Is equal splitting rude?
- Only when the gap is large. Below roughly a 20% difference in orders, equal splitting is faster and generally accepted.
- Who should pay the whole bill?
- Whoever has the fastest way to be paid back — usually the person everyone can transfer to instantly.
- How do we handle non-drinkers?
- Split the drinks separately. It is the single most common source of unfairness at the table.
