How this calculator works
- 1Contribution per member = monthly fee − variable cost per member.
- 2Break-even members = fixed monthly costs ÷ contribution per member.
- 3Margin of safety = (current members − break-even members) ÷ current members.
Formula
Break-even members = Fixed costs ÷ (Fee − Variable cost per member)
Tips from gym owners
- Keep break-even below 60% of your realistic capacity so one bad month does not sink you.
- Variable costs for gyms are small: payment processing, towels, water, app seats.
