Group expense calculator

Travel together.
Split smarter.

Split shared costs cleanly across a trip, a household, a dinner — and settle up in the fewest transfers possible.

Free tier includes 2 shared activities. No card required.
Chamonix Ski Trip, snow theme. Expenses grouped by day: 20 Sep — Groceries, Equipment rental, Gondola; 18 Sep — Fondue; 16 Sep — Ski pass.Alice Barcelona, sea theme. Expenses grouped by category: Hotel, Restaurants, Culture.Rome Weekend, city theme. Balance split with settlement transfers and a By Category donut.
01 / SHARED ACTIVITIES

Invite by email. See each other’s expenses live.

Anyone in the activity can add an expense. Balances update the moment they hit save.

02 / MINIMUM TRANSFERS

Settle in the fewest payments the group needs.

The math finds the shortest set of transfers that clears every debt.

03 / ANY CURRENCY

Enter in any currency. Convert once at the end.

No matter which currency you use in the trip, you can always convert to your home currency.

How it works

Three steps between a trip and a squared ledger.

01

Create the activity

Pick a name for your trip, set base currency and pick a theme — forest for hikes, sea for beach houses, city for weekends away.

02

Add people

Invite them by email if they use BalanceSplit, or add them as nicknames if they don't. Both work; balances still calculate.

03

Log expenses as they happen

Each expense is one row: who paid, how much, what for. Split it evenly, or pick specific participants when it's not an all-hands cost.

04

Settle up

BalanceSplit computes the minimum set of transfers and shows who pays whom. Share a copy of the split with your team mates.

Six themes because one trip doesn’t look like the next.

The activity card takes the palette of what you're actually doing. It's cosmetic, but it makes a long list of trips instantly scannable.

Three tiers.
The math is the same on every one.

The paid tiers raise the ceiling on how much you can track — the settlement algorithm and every feature work identically on Free.
