That would be over double the offer amount!! I don't think that would fly.

I have done some contracting before and my rate is far higher than my employment rate, but it's always been for smaller contracts... not for something that is effectively a full time position.

I am not an accountant or anything but I think a rule of thumb is employment costs 50% more than the employees salary. Don't feel too bad asking significantly more, after all you are not getting any equity which sounds like your main motivation.

That sort of rule of thumb is going to be most accurate for average salaries, because large amounts of the non-salary costs are relatively fixed (e.g. health insurance costs the same amount whether you earn $50K or $200K annually). As salary goes up, so does its share of total compensation.

Full time positions are dealt with using payrolling companies or SPVs as daughter companies under the mothership, not by independent contractors (with all of the associated risks) and a reduced rate.

You are making a lot of excuses for this company in this thread.
