ShortReckonings.com - Track Group Expenses

Short Reckonings is a free web tool to help you keep track of group expenses and reconcile debts. For instance, you could create an expense sheet to track shared expenses among your roommates.

After adding each household member’s name, you would enter a brief description of each expense, the amount spent, who paid it, and which roommates should split the cost. You can add as many roommates or expenses as you need, and Short Reckonings will do the math to tell you who owes how much to whom – in the fewest possible number of payments. Sheets can be printed, shared with friends (by passing along the unique URL for your sheet), or saved. Currently, you must bookmark your expense sheet’s URL in order to return to the saved version, and Short Reckonings deletes sheets after they are not accessed for 90 days. The site promises future versions that will allow you to create an account, where you could save all of your expense sheets together and indefinitely.
