Some folks refer to this as Income and Expenses - Businesses might refer to this as profit/loss or cash flow management.
Others may refer to it as household budgeting. Whatever you call it, it all means the same thing..... How much money is coming in and what is it being spent on?
How well you manage this aspect of your finances determines everything else. How well are you doing? Can you do better? What is right for you? What about debt? Are you using it wisely or is it becoming a bigger and bigger expense?
Far too little time and effort are spent on this part of our finances and yet it is the cornerstone.
