A great way to start budgeting your money is, always keep track of what you earn and what you spend. Give yourself allowances for what money can be spent and what should be saved. You have to know your spending habits so you can determine ways to save and maybe make some cuts. Regardless of how much you may earn it's always a good idea to know how it's being spent, bills, fun, food, etc..
There are many apps out there that will help you in keeping track of where you are spending your money and where you can possibly save. Or even just writing down your expenses on a weekly basis to give you a better idea.
