If you do find a budgeting worksheet that you like, you can simply add categories to it or replace the ones you won't use with your own items. For example, many of these worksheets that you will find online have a place for investment income but if you don't have any investments to track either ignore that category or replace it with one of your own. _Once you view a few of these templates, you may realize that you have more categories of spending than you thought. For example, when first creating a budget, many people forget all about gifts, subscriptions, and pet expenses but by working with one of the preprinted templates, you may remember additional expenses you need to consider.
Next, you will want to fill out a monthly financial report worksheet where you record you income and come up with your net spendable income after taxes and any charitable giving. Then you want to take your totals from your monthly expense record worksheet and fill in all amounts in the categories such as household, food, medical, transportation, and recreation just to name a few. When you total up your expenses and subtract them from you net spendable income you will see if you have a surplus or not.
