How do I split a bill evenly?

Add the tip and tax to the bill, then divide by the number of people. A {{$120}} bill plus 20% is {{$144}}; four ways, {{$36}} each.

How do I split a bill when people ordered different amounts?

Choose 'by what each person ordered' and enter each person's total. Each pays their own order plus the same percentage for tip and tax, so the extra is shared fairly.

Should tip and tax be split evenly or by what people ordered?

By order is fairer when orders differ a lot, because tax and tip are percentages of what was ordered. Even is simpler and close enough when they are similar.

What if the share does not come out to whole cents?

Someone pays a cent more. The page notes when the split does not divide evenly.

How do I split a bill with tax and tip when only some people drank?

Use 'by what each person ordered' and put each person's drinks on their own row. The tip and tax percentage then lands on each order in proportion, so the drinkers carry the share of the tip their drinks generated.

What each Split Bill input means

Split: Evenly when everyone had about the same; by what each person ordered when they didn't, so the tip and tax follow the food.
Bill total: The bill before tip — and before tax too, if the tax isn't on it yet. The extra percentage below is added on top.
Split between: How many equal shares. Include yourself.
Who ordered what: In 'by order' mode, one row per person with what they ordered. Shared dishes can go to one person or be split between rows before you type them in.
Extra (tip, tax, service): Tip, tax and any service charge as one percentage on top of the bill: 20% tip plus 8% tax is 28%. If the bill already includes tax, enter only the tip.

Split Bill formula

even: each = bill × (1 + extra %) ÷ people · by order: each = their order × (1 + extra %)

\text{each}_i = a_i \times \left(1 + \frac{p}{100}\right)

There are two fair ways to split a bill. When everyone ate about the same, add the tip and tax as one percentage and divide the total by the number of people. When they did not — one person had a starter and a glass of wine, another a salad — each person's share should be their own order plus the same percentage on top, so whoever ordered more also pays more of the tip and tax. The page does either: switch to 'by what each person ordered' and enter each person's items total.

Split Bill worked example

A $120 bill with 20% added for tip and tax is $144, so four people pay $36 each. Split by order instead — $32, $18 and $25 for three people — the 20% is shared in proportion: $38.40, $21.60 and $30, still $90 in all.

More Split Bill examples

A $187.50 dinner for three with an 18% tip: $187.50 × 1.18 = $221.25, and $221.25 ÷ 3 = $73.75 each — an exact split, so no cent is left over.

Where the Split Bill calculator can give the wrong answer

The extra percentage covers tip, tax and service together. If the receipt already includes tax, add only the tip percentage.
Shared dishes can go to one person or be divided between rows by hand before you enter them.
Rounding to the cent can leave a cent over; someone pays it.
