For an update, the article "[ How Much Should Photographers Charge In 2016? ][1]" could give some help.

So:

> **Amateur: $25 – $75 per hour.** (...) Different types of photography lend themselves to different pricing models. Event photography is generally based on an hourly or day rate. When it comes to commercial photography, some photographers, like me, charge on a per-image or per-project basis.
> 
> Depending on the photographer, the per-image pricing model is lower risk for the photography buyer, and rewards for the photographer for a job well done. Some photographers charge as little as $25 per photo, while top photographers receive thousands of dollars for a single photograph. (...) Rates also fluctuate depending on location. (...)
>
> **Student: $50-100 per hour / $25-100 per image.** As with all types of photography, the student rate varies, depending on their photographic discipline, industry experience, and interaction with, or assisting, professionals. Some advanced students do – and should – command as much as professionals. (...)
>
> **Semi-Pro: $50–$150 per hour / $25-125 per image.** These are photographers who have ambitions to join the ranks of the professional. They may have another job or income source to keep them afloat, but which they aim to leave behind. Sometimes their additional skills are compatible with their photography. Many compete with professional photographers for jobs, but are not quite ready to jump in with both feet.

For a professional:

> **Senior Portrait Photography $125-$300.** This rate depends on many factors, such as the number of locations, changes of clothes, and reprint package that you chose. (...)

And now, ask yourself:

> – How much do I wish to earn in a year?
> 
> – How much are my annual business expenses?
> 
> – What’s my marketing budget?
> 
> – How many days will I likely work next year?
