Here are some resources for learning to price commercial photography. But I’m not vouching for any of these. A photographer would be foolish to base their business practices on numbers from someone else’s web site. Use these for informational purposes and to help understand the underlying principles.
— The News Photographers Association of Canada Cost of Doing Business Calculator (CODB) is a good place to start. You may be surprised at your CODB.
— The Canadian Association of Professional Image Creators has a PDF listing suggested minimum usage fees (i.e. licensing fees only). Main page > Useful Resources > Resources > Reproduction Fee Schedule. The site has other useful information.
