With this calculator, you can easily estimate your daily budget based on your income, planned expenses, and current expenses for a given month. By going to the "Income" tab, you can add the value and description of your income (for example, your salary, bonus, cash gift). The "Planned" tab is your planned expenses (for example, fuel, installments, planned purchases for a given month). You can edit or delete each record. After making purchases, enter the amount of these purchases in the main window and click the "Calculate" button to update the budget. The "Reset" button allows you to clear the sum of current expenses when you decide to modify the calculation or it is simply a new month and the calculation should start from the beginning.
