Bill Split

Features

• Split evenly (AA) or item by item, switched with one option
• Each person’s share listed, with what they ordered plus their tip and service allocation
• ⚠️ The rounding cent goes to one person and is named, so the shares match the total exactly
• ⚠️ Tip before or after the service charge is an option, and the result states which was used
• Any line can name its participants, so only those who ordered it share that item
• Tip and service charge are allocated in proportion to what each person ordered
• Amounts are handled in whole cents and always shown with two decimals
• Runs entirely in your browser

How to use

1. Fill in the list of people (or leave it empty to derive it from the lines)
2. Write one item per line as “name, amount”, adding participants where needed
3. Set the tip and service charge, and choose whether the tip includes the service charge and whether to split evenly
4. The result gives the total and each person’s share, and says where the rounding cent went

FAQ

Why is there always a cent short or over?

Because 100 divided by three does not come out even. Three people at 33.33 pay 99.99 — a cent short. The largest-remainder method gives that cent to one person and names them, so the shares add up to exactly the total.

Should the tip come before or after the service charge?

It depends on the restaurant and on what you agree. Adding the service charge first and tipping on the total costs a little more; charging both on the food alone costs a little less. Both are options here, and the result says which was used rather than leaving you to work it out.

Someone did not drink — do they still pay for the wine?

No. Put the participants on the wine line and only they share it. Tip and service charge are allocated in proportion to what each person ordered, so a non-drinker does not tip on the wine either.
