Frequently asked questions

What is included in employer taxes?

Employers pay part of Social Security and Medicare (FICA, 7.65% of wages), plus federal and state unemployment taxes, and often health and retirement benefits. The default 10% is only an example. Enter the total percentage that applies to your employee.

Is this an official payroll calculator?

No. It estimates your cost for planning. It does not calculate withholdings or paychecks, so use payroll software or your accountant for official amounts.
