Does anyone who's been in this situation have a guideline for how much $salary generally equals how much $contract? Is it, like, "Take your yearly income from contract, multiply by 0.85, and ask for that much"? If so, what's that number?
It's not that simple.
Fulltime is clearly less per hour, but it includes paid
vacation and sick time...which I've never had, uh, my whole life.
Just a few things to consider that I haven't seen mentioned yet:
* Sick time has zero value unless you use it, because if you aren't sick you'll be working and making that money anyway.
* Vacation time is nice...but it's value is questionable, because again...you're simply being paid to not work as opposed to being paid to work. Without the vacation time, you would be getting paid for that time anyway. Having two weeks off to go to the Bahamas is nice, but having that time and an assurance that the job will still be waiting for you when you get back is the benefit here. That's not a financial benefit. Assigning it a dollar value is difficult.
Incidentally, if you're a contractor...can't you take time off whenever you want it anyway? Just tell them you're going away for a few weeks. You don't need their permission. Sure, they might not still need you when you get back...but that's the nature of being a contractor. More flexibility, less security. In general, company benefits are about feeling secure. How important is feeling safe to you? Again, it's difficult to put a dollar value of things like that.
* As for things like health and dental...like above, they don't really have much value unless you use them. Plus, you need to know the details to even figure out how valuable they are even if you do use them. What's the deductible? For example, if their program has a $500 deductible, that means that every time you go to the dentist or doctor, any expense up to $500 must be paid by you. They only cover expenses above that. So...you might feel all nice about having your health benefit with a $500 deductible that on paper is theoretically "worth" $2000 salary per year, but if you visit the doctor 5 times over that year and each visit costs $300, you pay $1500 for those visits and the net value of the benefit to you was zero. Whereas if instead of having the health benefits "worth" $2000, you simply had $2000 more annual salary, you'd have paid the same $1500 in cash and would be $2000 ahead of where you'd be with the health benefits: $500 ahead instead of $1500 in the hole.
It's not my intent to simply bash salaries positions. They can be better. But don't assume that they are just because you expect them to be. If a company wants to move you from hourly to salaried, there's probably an incentive for them to do so. That incentive might be that they'll be able to work you more for less money.
You'd need more information than has been provided in this thread to make a proper determination. However...
"Take your yearly income from contract, multiply by 0.85, and ask for that much"?
...if your multiple is less than one, that means you get less money. I realize this is obvious. But I'm pointing it out anyway. Ask yourself if these other benefits they're offering you are worth receiving less money.
