When and how to split shared costs
Dining, travel, and shared living.
Built for restaurants & dining
The classic case: a shared bill at dinner. Enter the total, the number of diners, and the tip — get the exact per-person amount including tip and tax in one step. The whole-dollar mode gives a clean number to collect at the table.
Group travel and shared costs
Trips generate Airbnb, car, fuel, groceries, and meals. The simplest system: one person pays each expense, tracks the running total, and uses this calculator to find each person's equal share at the end. Send a payment link for the per-person figure to settle up.
Flatmates and shared living
For recurring costs — broadband, utilities, household supplies — a shared account everyone pays into equally is cleanest. For one-off purchases, this calculator confirms the split instantly. Where usage differs a lot, consider splitting by usage rather than pure equal division.
How the Expense Split Calculator Works
Formula
Tip = Amount × Tip% ÷ 100
Tax = Amount × Tax% ÷ 100
Grand Total = Amount + Tip + Tax
Per Person = Grand Total ÷ People
Rounded = ceil(Per Person) → buffer = Rounded × People − Grand TotalEnter the total amount
The shared bill before tip (and tax, if you add it separately).
Set the number of people
How many ways the cost is split.
Add tip and optional tax
Tip and tax are added to the total, then divided equally.
The base split divides the bill equally. Tip and any tax are added to the subtotal first, then the grand total is divided by the number of people — the standard, fairest approach when everyone shared roughly equally.
The whole-dollar collection mode rounds each person's share up to the next dollar and shows the small surplus it creates, giving you a clean number to collect that can top up the tip or cover the rounding.
