Making a spending diary gives you an idea of your total weekly expenses. We don't always keep track of everything we spend every week. For instance, you might go to the local newsagent to buy a newspaper or buy a soft drink. Or you might buy some sweets for the kids after school. It's this kind of spending that we don't always think about and often forget about, and it does add up! If you want to review your spending, using a monthly Spending Diary can help you do this, and it can also help you identify areas where you can reduce your spending.
