The fee you charge should always be relative to the current demand in the marketplace for your services. If you have no clients, than charging say $70-100/session probably isn’t wise, even if you are in a market than can afford to do so. That is, why not make your price an attraction as opposed to an obstacle if you are attempting to build a client base? On the flip side, if demand is high (or if demand gets high once you have your clients) than it is logical to charge a premium price for your services, assuming your services warrant such a price. Of course, as others have said the demographic of your target market must always be taken into consideration as well.
Simple stuff, nothing fancy. At least that is how I approach it. Good luck!
this is an easier question to answer than you would think.
how much money do you need to make /month?
lets say you need to make 4000$ and you have 6 hours per day to train on 5 days per week. So you have 30 hours of training/week or 120 hrs of training / month. this works out to be a minimum of $33.33 per session to make your minimum per month. I charge $60/hr but I started out at $50 with package deals that put me as low as $25 for a 6 month package payed up front. Now I don’t offer deals my time is valuable to me and I have learned not to try to get every client I can but to pick the ones that I will work with best.
This is just an example and will depend a lot on what your bills are, if this is your sole source of income, how long your projections are of training full time, and your overhead.
