Paid Community Revenue Calculator accuracy and testing

Formula source

• Gross monthly revenue = active members x monthly price. Total fees and costs = gross revenue x platform fee + gross revenue x payment fee + active members x fixed payment fee + monthly content cost + support hours x support hourly value. Net monthly revenue = gross monthly revenue - total fees and costs.
