You should treat your savings as the most important bill/obligation that you have.  Always pay yourself first.

Retirement Savings:  10% of your net income

Your personal retirement savings is necessary even if you have a retirement plan with your job and plan on receiving social security when you retire.  If you work for yourself a personal savings is definitely necessary because social security will not be enough to sustain the lifestyle you have adapted to throughout your years of working.

Essentials Savings for a year: 5% of your net income until amount is met.

This includes things such as rent, mortgage, utility bills, food, gas, etc. These are the things that you cannot live without.  Save 5% of your net income until you save enough money to be able to pay your essentials for a year.  After saving enough, you can put that 5% towards anything that you want.

Emergency/Large purchase Savings: 5% of your net income until amount is met.

This particular savings is necessary, so that you don’t have to go into your other savings.  All types of emergencies occur, so it is best to be prepared.  When making big/large purchases—it’s best to have the money already.  The amount saved in this category is really up to you, but please save enough as you can, so that you don’t disrupt any of your other financial responsibilities and goals.
