UnderBudget allows you to create a personal budget and track your ongoing progress (so that you stay under-budget) by comparing against your actual expenses.

• Categorizing of estimates into a hierarchy (e.g., Expenses->Food->Groceries and Expenses->Food->Dining)
• Ability to import transaction data from GnuCash
• Assignment of transactions to estimates through flexible user-defined rules
• Calculation of:
  • estimated ending balance (initial balance + estimated incomes - estimated expenses)
  • actual ending balance (initial balance + actual income to-date - actual expenses to-date)
  • expected ending balance (actual ending balance, taking into account estimates that have already gone over-budget)
• Uses the Qt framework to run on Linux, OS X, and Windows

Start by downloading the appropriate package for your operating system and follow the installation guide.

UnderBudget can be built from the source by cloning the repository and following the build procedure.
