Step 1: How much is 3%

We are going to focus on pre-tax investing.  Investing in a Roth account is definitely a great thing to do, but until you receive 100% of your company’s match, I would focus on the traditional retirement plan options.  

Let’s take our example of $15 an hour and multiply that by 40 hours a week.  That would be $600 of income before taxes.  If you were to set up your automatic contributions at 3%, you would be adding $18 a week to your retirement account.  $18 is definitely manageable.  

It gets even better, though, since you contribute before taxes, you are not claiming the $18 as income.  Let’s assume that you have a 20% tax rate (this will vary state, federal & payroll).  Your paycheck will only be short, approximately $14.40.

Since we are assuming a company match of 3%, you will be contributing $36 per week to your retirement plan.  That is $1,872 per year,  with compounding interest that can turn into a nice retirement plan in 30 years. Also, remember that your yearly income is only down $748.80 despite putting in $1,872.  That may seem like a lot of money but read the next step to see what it can grow to with no further changes.
