Expense Split Calculator

Group trips and shared bills rarely split evenly. One person pays the hotel, another covers dinner, and nobody remembers who still owes what. Enter what each person paid and get a clear, fair settlement plan in seconds.

Everyone shares the total cost equally. List what each person actually paid, and the calculator works out who owes who.

      How expense splitting actually works

      Picture a road trip with three friends. One pays for gas, another books the cabin, and the third grabs groceries. Nobody paid the same amount, but everyone should still cover an equal share of the total. That gap between what someone paid and what they owe is called their balance.

      A positive balance means that person is owed money. A negative balance means they still need to pay in. Settling up just means moving money between people until every balance reaches zero, using as few payments as possible.

      The formula, broken down

      Fair share = Total spent ÷ Number of people
      Balance = Amount a person paid − Fair share

      A positive balance shows how much a person is still owed. A negative balance shows how much they still need to hand over. The settlement plan simply pairs up the biggest debts with the biggest credits until both hit zero.

      A worked example

      Four friends went camping for the weekend. Here is what each person paid.

      PersonPaidFair shareBalance
      Alex$120$55+$65
      Jamie$60$55+$5
      Sam$40$55−$15
      Riley$0$55−$55

      Total spent was $220, split four ways at $55 each. Riley pays Alex $55, Sam pays Alex $10, and Sam pays Jamie $5. Three simple payments, and everyone lands at zero.

      Frequently asked questions

      They still owe their full fair share. Their balance simply shows as negative, meaning they need to pay in.
      This tool assumes an equal split, which fits most shared trips and meals. For a deliberately uneven split, adjust each person’s paid amount until the balances reflect what you agreed.
      No. Pick one currency for the whole group first, so every amount stays directly comparable.
      It matches whoever is owed the most with whoever owes the most, then repeats until every balance reaches zero. This keeps the number of payments as low as possible.
      No. Every calculation runs in your browser, and nothing is stored or sent to a server.
