Cash flow forecasting is like planning the budget for a family. It helps us to predict how much money we will have in the future, how much money we will need for different things, and how much money we can save. For example, if you run a business, you can use cash flow forecasting to figure out how much money you will need for rent, wages, supplies, and other costs. By predicting these costs and comparing them to your income, you can decide how much money you can afford to spend and how much you should save.
