About net cash flow
Near the bottom of your budget is the row that shows the calculated "Net cash flow" for each column: income minus expenses and set asides. The net cash flow numbers indicate the direction of your spending plan. A net cash flow that is negative (red) indicates that on that column date you plan on spending and setting aside more money than will be available.
Being able to see a twice monthly net cash flow for the next twelve months is the main benefit of using A Real Budget. You can foresee shortfalls in your spending plan and make adjustments before they become problems.
