I am not from the USA, so part of W-2 and 1099 goes beyond me, but I will talk about the rest, because these problems are quite universal.
Generally speaking, the rule of thumb is that if you earn $ 100,000 per year, you must charge $ 100 per hour, or close to it. This should cover some or all of them:
- Lack of personal / sick leave;
- No paid annual leave;
- No bonuses;
- No training;
- Insurance (healthcare, state responsibility, professional compensation, etc.);
- If you do not work with a certain number of hours per week, there is variability in income;
- An employer can get rid of you much easier than a full-time worker.
Now this is my experience in Australia and Europe, where you really have quite significant public medicine. I would suggest that since you are not in the United States, health insurance costs may lead to even greater growth, so perhaps you should ask for $ 120 per hour.
Note: if you don’t pay for things like professional insurance or you don’t have any legal protection (for example, through a limited liability company), you play with fire, and I urge you to seek professional advice on establish a structure and / or obtain appropriate insurance to adequately protect you, your assets and your family, if you have one.
Of course, you must balance all of this against the current market conditions, which are not so great (but vary from locale to locale).
I like the hourly scenario because it is "fair." By this I mean that if you work 80 hours a week to get something, then you get paid for it. You just get paid for what you do and what it is. It's simple.
Now employers often do not like it because they cannot necessarily predict (and, therefore, the budget) costs.
The next step is to pay a daily rate. I usually try to resist this, but I will follow him in certain situations. If so, you need to pinpoint what a day is.
- If you work at all, do you get paid for half a day? Full day?
- Do you need to work a certain number of hours to pay per day?
- Are you only paid for the full day no matter how many hours you work on that day?
- Can you get more than 5 days a week?
As a rule, for such situations, I will gradually change my hourly rate to 9, basing it on an 8-hour day. You take a certain risk, so you need to pay for it.
In addition, you can switch to weekly and then monthly. They also have the problem of determining what constitutes a week or a month. There are an average of 20 or 21 working days per month, so multiply your daily rate by 21-25 to get a monthly rate.
Regarding the negotiation strategy, make the most of the points listed above. If $ 120 / hour sounds like a lot (for them), list all the costs, which are also the costs that they save. Use your proven track record to your advantage, because I can guarantee that for a company there are several things that are disastrous for a company than incompetent software development.
