I've found that when creating a budgeting worksheet the best way to start is with a set up like this; _ Firstly, place your pay dates along the top (shown from A1 to G1). These can be weekly, fortnightly or monthly or any period that you normally work from. _ Then list out each income source and the amounts you receive from them. For irregular payments such as Christmas bonuses etc set up a row specifically for this and maybe name it "Other Income".
Cut out. Lots of us pay for things we do not even use. This is another mistake that gets easier to make with so many automated payment plans. Do you keep a gym membership that you do not use? Replace that with a brisk walk, weights, or a stationary bike. You will not have to make monthly payments, and you may find it is more convenient.
