It's important to complete and Monthly and Year-End Financial Review because it will help show how much you have saved and how much you have spent for each month, and the whole year. This is important because it will help you prepare for the future. For example, I am a General Manager at Sonic and we have a PnL sheet that shows us our profit and losses from the current month and year, but also the same month last year, and the previous year as well. Using this allows us to see the areas we can improve on to increase our controllable profit to allow myself, our employees, and the company to make more money. Personally I believe any financial review is good, and there isn't really a "too often". Looking at how you spend money daily or how much you are saving daily can help you cut down extra expenses. Going day by day will also see how much you are making towards any investments or your retirement plan, and this can also help you compare to the same days as last year and see if you are gaining profit or losing. This will let you see the good and bad on your investments and allow you to work out any kinks you may need to to begin making profit and saving money.
