To create a personal training business plan, you must first decide what type of service you are offering. Then write down your pricing and services offered in the form of bullet points. Next, state how much money it would take for you to be profitable if each client pays $50 per month. You can then break this number up into time frames that indicate when certain periods will have their own profitability numbers listed next to them (monthly projections). Finally, give yourself an expected profit margin percentage on top of that monthly projection figure which is based off historical data from past clients who paid similar amounts for similar services as outlined by your plans fees.
