A while back, we featured a handy online tool that will generate invoices for your freelance projects. Now, the company behind that tool has added another one to its repertoire: an hourly rate calculator.
This tool takes into account your current salary (or how much you'd like to make), factors in monthly or yearly expenses, and generates an hourly rate you can use to charge clients. It even includes space for how many days of annual leave you'd like to take each year, or how many billable hours you work each week. While experienced freelancers know that sometimes work isn't consistent enough to plan that far ahead, this should give you a baseline for the type of rates you should charge to maintain a reasonable income based on your needs.
