Shows optimized payment plan minimizing number of transactions needed to balance accounts. Essential for group trips, shared apartments, dinner parties, event planning, and any situation where multiple people share costs.

Used by friend groups, roommates, families, travel groups, and event organizers to maintain financial transparency.

How to Use This Calculator

List all participants in the group. Enter each expense including who paid, total amount, and who should share it (everyone equally, specific people, or custom percentages). For restaurant bills, enter total and select whether to split equally or assign items to specific people. Add individual expenses that should not be shared (personal drinks, separate activities). Calculator shows running balance for each person—negative means they owe money, positive means they are owed. Results display optimized settlement showing minimum payments needed to balance accounts. For monthly shared expenses like rent or utilities, create recurring expense templates. Export summary for group review showing all expenses, each person total spent versus share owed, and final settlement amounts. Best practice: agree on split method before incurring expenses to avoid disputes.
