Settle a group bill fairly
When a group of people shares a set of costs and different members happen to pay different amounts along the way, working out who owes whom at the end is genuinely fiddly and error-prone. This splitter takes simple payer-and-amount lines and computes the full settlement transfers for you, showing precisely who should pay whom to make everyone even again, and doing it with the fewest possible individual payments.
Why netting beats reimbursing
If four people each paid for something different during a shared trip or meal, reimbursing every single imbalance directly would mean a confusing tangle of many separate payments criss-crossing the group. Netting instead works out each person’s genuinely fair share, compares it against what each one actually paid, and then finds the minimal set of transfers that settles all the differences at once. That turns a messy tangle of who-owes-what into a short, clear list of payments, which is both demonstrably fair and simple to actually execute, and doing it correctly by hand for a group is exactly the kind of thing people get wrong.

Frequently Asked Questions
How does it settle the bill?
It computes each person’s fair share, compares it to what they paid, and finds the minimal set of transfers that makes everyone even.
Why netting instead of direct reimbursement?
Because reimbursing every imbalance means many crossing payments. Netting finds the fewest transfers that settle all the differences at once.
What do I enter?
Payer and amount lines, who paid how much, from which it works out the shares and the settlement transfers.
Does it handle any group size?
Yes, and larger groups are exactly where it helps most, since manual settlement gets error-prone quickly.
Is my data uploaded?
No. The calculation runs entirely in your browser.
