Check out this
article about how to calculate your hourly rate manually.
The calculators provided here are a way to automate that process and
keep up over time.
ProfitWatch is our original hourly rate calculator and was born out of the classes Mark taught in the "Exhibitor Presents" series at NBM shows in 2004 and 2005.
RateMate is our first Mac OS X program and is a port of ProfitWatch for Windows.
RateMate is also available for iPhone (and a little cheaper!)
