In life, we may spend our money for various unexpected reason. Being sick as example, is not something that is well planned by any one. The same thing is also happened for you who have a car accident. No one expected to spend his own money for this kind of reason. But that is life. If you want to have this kind of condition is under control, sparing a certain portion of your salary for this unexpected situation is needed.
Another thing that you have in life is the other fluctuating expenses that are related with your life style. Watching a movie, enjoying a rock concert, going on a holiday in Hawaii, buying a fancy dress and much other small stuff are the kinds of activity that influence your fluctuating expenses. This kind of expenses is not fully related with your basic need. And using the pay day loans to finance your extravagant holiday as example is not advisable. Reducing the level of this kind of expenses will help you to allocate your money into a better condition.
You may set the spared money to your personal saving. But remember this; saving is good for you only in a short term. You have to keep it in mind that economically, your money value is changed. The reason is related with the fact that the national inflation has influenced many things. The level of saving interest and the loan interest as example is related with the national inflation rate. The other related problem with saving is also connected with the fee that should be paid to enjoy the bank financial services. If you have a low amount saving in your bank account, there will be possibility that your money will be shrinking due to the fact that the amount of saving interest that you get is smaller than the amount of the fee for your bank services.
