That is an interesting question, and I would say $12,000-$24,000 a year, more with experience and a solid client base. The rewards of a freelance writing career are far greater than the monetary rewards, but at the same time, income is important. This is especially true if you plan to make a living as a writer.]
Factors that affect a writer’s income
Well really it depends on how much the writer charges (per word, per article, per hour, etc.)level of skills and experience, client retention (Does the writer have clients who return, or just one time clients?), networking/marketing ability/efforts,-how many projects they can handle and the types of projects done/writing niche (some types of writing just get compensated better than others)
How can a writer earn more?
Persistence. If you are determined to earn a living as a writer, you will do it, eventually. You have to be willing to put in long hours of networking, marketing, promoting and applying for work. The wider you cast you net, so to speak, the more fish you will catch.
Charging higher rates is tricky. It can be done, however, the market is unfortunately weighed down by writers who accept pittance for their work, which makes competition difficult. This is yet again where persistence is needed. If you value your work highly, and always offer the best quality to your clients, there will be those who are willing to pay for that quality. Depending on the niche, you may be able to charge quite a bit (a few dollars per word). Your rates should also match your experience.
Keep clients coming back. The more repeat clients you can get the better. Over three years, I have managed to retain five clients. Many of my other clients have used my services two-five times. Treat every client as if they are special, and always do your best work. When you search for jobs, look for long-term work. Not every project will lead to more work, but it does happen, and you should try to close projects well, and keep lines of communication open.
Manage your time well. The more time you put in, the more work you can get done, and the more networking and marketing you can do. If you are disciplined with your time, you will be able to spend the time necessary to build a solid client base and keep new work coming in. Time management is probably the most crucial element in earning a living as a freelance writer. The less time you waste, the more money you will make.
Be patient. After a few years, you will get better at determining what will bring in the most money for you. There is still a lot of money in copyrighting for businesses and magazines. Web content writing is needed more and more all of the time, however, these jobs tend to pay less. With time and dedication, you can grow your business gradually and get to the point where you make a couple thousand or more per month. Just know that it is not easy.
