Calculating Monthly Expenses To have a secure financial life you need to know your monthly expenses. Look for ways you could cut down your expenses. You can consider cutting your expenses on grocery bills, food, cable etc. You are wasting your money by paying for services you don't really avail. Instead shop around for all the monthly services you use. You could do the same when it comes to buying an insurance policy. Consider calling your insurance company to see if you can get a better deal. If you do find a better deal with another insurance company, call your current provider and ask if they can match it. Cut back on anything you don't value
