Solo alternatives

Obviously, anything made in spreadsheets has a lot of room for UI improvement, but those struggles are all meaningless when you recognize the value of this calculator. As a freelancer, it's always unclear how much money you're actually taking home from a project and making sure you're not underpricing yourself. This is something that gets better over time as a freelancer, but in the mean time he/she is leaving money on the table, underpricing themselves, or, worst case scenario, losing money on projects. I'm super impressed by the ease of use and value of information.
