The Wage & Salary Conversion Calculator on the website of the Iowa Workforce Information Network and the salary-wage converter on CalcXML.com are two calculators for determining the hourly wage of a salary. Both are online-based and free to use as of 2015.
On the website of the Wage & Salary Conversion Calculator, select a pay period from a drop-down menu, enter the average number of hours worked weekly and the annual salary amount, and click Calculate to convert a salary into hourly wages. The converter automatically offers results for weekly and monthly totals based upon the same entered data.
On CalcXML.com, enter an amount into the Annual Salary field, and click Submit for an hourly, weekly and monthly breakdown based on a 40-hour work week.
