Employee benefits are either required by law or voluntarily offered. Required benefits include employer FICA, FUTA and SUTA unemployment insurance, and workers compensation. Optional benefits are the employer’s choice and directly affect recruiting, retention, and compensation cost.

The key challenge is modeling cost before committing. Adding health insurance for 10 employees adds $85,000 to $100,000 annually. The calculator below shows total costs for any payroll size.
