Calculation breakdown
  1. Each share = total ÷ number of people
  2. Balance = amount paid − share
  3. Those with a negative balance pay those with a positive one, starting with the largest amounts.

Indicative result based on the data you entered. It does not replace a professional quote or your actual bill.

How it is calculated

Each share = total ÷ people (equal) or total × weight ÷ sum of weights (proportional).

Balance = paid − share. Negative balances pay positive ones, largest first, which keeps the number of transfers low.

Worked example

Using the calculator’s example values:

  • How to split: Equally
  • People and what each has paid: 3 example rows

Result: Total shared spend — $165.00 (transfers needed: 2; each person’s share: $55.00).

Money-saving tips

  • Agree on how to split before you start spending.
  • Log expenses the same day so none are forgotten.
  • For couples with different incomes, proportional splitting is often seen as fairer.

Frequently asked questions

What goes in “weight”?

Any number reflecting the agreed proportion: salary, days each person stayed or a percentage.

Why are there fewer transfers than people?

Because the algorithm matches debts and credits directly instead of routing everything through one person.

Are cents rounded?

Transfers are calculated in whole cents so they balance exactly.
