Anything else that you spend money on
After you have made your lists, you are going to need your bank statements and credit card statements. Looking at one average month (or more if you want) of spending, use the amounts you typically spend as reference values. Review all transactions - incoming and outgoing - in these statements. Don’t forget to include expenses that you do not have every month but maybe in other intervals. Look at the amounts you spend every month on each item and write them down for each item. Finally add up your income and add up your expenses.
How to calculate net income
Now you take the sum of your income and subtract the sum of your expenses that you have added up and write down the amount, regardless of whether it is positive or negative. The figure will hopefully be positive, meaning that you are not spending your entire income, or more than your actual income.
How to review your spending habits
Now it’s time to analyse your spending habits in closer detail. Are you possibly spending more money that you have coming in? If your expenses amount to more than you actually have incoming, this is known as “going over budget”. Carefully look at all the details in your spending list to figure out where you are spending too much money and where you could be spending less.
Adjusting your spending habits as quickly as possible will save you a lot of trouble later on. You should identify expenses that are not necessary or where you could switch to a cheaper option. It obviously depends on your personal situation, but earning more than you spend – even if it’s just a small amount – is crucial.
