Self-employment and the basic 15.3% Social Security payment needs to be considered. Yes, that is double the deduction, you would see from your pay check, each week. What seems like a good charge-out rate of $50 per hour, may need to be $75, when you include the cost of health insurance and social security. A lot to consider. Self-employment is not for everyone. IMO, Mike CT.
$75/hr. may not be enough. Often hourly rates are translated into piece, or part work.
Collection another part of business to be considered.
