About Restaurant Bill Share Calculator

An itemised split charges each person for what they ordered plus an equal share of anything shared — starters, sides, bottles of wine. Service charge is then applied proportionally, so each person pays service on their own subtotal rather than an even split of the whole charge.

Formula

Itemised share

my share = my items + shared items / people, then x (1 + service charge%)

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why apply service charge proportionally?

Because it is a percentage of the bill. Splitting it evenly would mean a light eater subsidises the service on someone else's expensive meal.

Is a service charge the same as a tip?

No. A service charge is added by the restaurant and may or may not reach staff; a tip is discretionary. Check before adding both.
