In these days of austerity, benefits are being cut and prices continue to rise. It has never been more important to be careful with your money, as getting into debt can spiral out of control and have dire consequences. A first step in taking control of your finances is to understand what you spend your money on. This sheet will help you work this out. To do it accurately you will need to record your spending carefully for several weeks but you may be able to estimate figures until you have got more accurate information.
Fill the figures in for an average month. So for example if you pay an MOT fee of £54.85 each year this would be recorded as 54.85/12 = £4.57 a month. If you spend £10 at the pub once a week that would be recorded as 4 x £10 = £40.
There is also an on-line version which does the sums for you here.
