How to calculate an hourly rate. | |
Hi, | |
I've been watching job boards for Ruby related contracts lately and have noticed some low rates being offered with high expectations. It's happening frequently enough that I wanted to post my understanding of how to calculate an hourly rate. Setting *reasonable* standards of pay for the appropriate level of expertise is vital. There's a lot to say on the matter, so I've tried to be brief. | |

The difference between full-time employment and self employment. |
