text: how much money should i have left after all savings and bills and paid out of each month? i'm a single divorced mother of a 5 year old, with no government assistance or child support. i'm also a student. i really would like to know an actual dollar amount. it is nice to know that someone your age is thinking about the future.  it is wise to put 10% on your earnings into some sort of savings.  hopefully you will have money left over at the end of each month to enjoy with your family.  there is no set amount.  it could be different each month.  just try to save at least 10% for the future.
