Forecasting income on a monthly basis should be beneficial to your business. Although predicting the future may be difficult, depending on the type of business you own, forecasting income is necessary to track your progress against budgeted goals.
Your monthly forecast should include figures for sales and all expenses. Sales may be challenging to predict. If you have a new business, you can examine the industry. In an established business, you can look at previous figures and current trends.
At the end of the month, compare your actual figures to your forecast. You should try to figure out why there is a difference, and make adjustments. For instance, if your sales fall below your expectations, you may lower costs for the rest of the year.
