How much money can I make writing?

The answer to this varies, since writing can be used to bring in a few extra hundred dollars a month, or it can be a long-term career that you pursue. What matters most is your writing goal. You can make anywhere from $500 to $10K+ a month , depending on the writing vehicle you pursue.

What do I need to start making money with writing?

Not much. You can be an absolute beginner and start to write for money in a few weeks if not earlier. Preferably you would want to start by being a guest on other people’s blogs or websites and have published some of your work publicly, although not completely necessary.
