How much does it cost to open a small gym?

A small boutique gym (3,000-4,000 sq ft) typically costs $50,000 to $150,000 to open, including lease deposits, equipment, build-out, and marketing. A full-scale commercial gym with extensive equipment can exceed $500,000. Buying used equipment can save 40-60% on the largest line item.

What is the most expensive part of opening a gym?

Fitness equipment is the single largest expense, ranging from $30,000 for a basic setup to $150,000 or more for a comprehensive mix of cardio and strength machines. The commercial lease deposit is typically the second largest cost, especially in high-traffic locations.

How many members does a gym need to be profitable?

Most small gyms need 200-400 active members to cover expenses and generate profit, depending on membership pricing and overhead. At an average rate of $40-$60 per month per member, a gym with 300 members generates $12,000-$18,000 in monthly membership revenue.
