But what about Administrative fees?

PEOs really have an extraordinary range – they can be anywhere from $49 per month per employee to over $150 a month per employee. Yes, that sounds high but remember you probably save way more than that on the Medical, Workers Comp and Unemployment. Some PEOs also charge a percentage of a payroll basis, and this is often the best pricing model for those companies with lower-paid employees. Those costs might range from 2 to 3.5% of payroll. (some also charge by check)
