Quick Answer: Member acquisition cost (MAC) is the total marketing spend divided by new paying members acquired. For most boutique fitness studios, sustainable MAC is 10–20% of first-year member LTV — if a member generates $2,000 in their first year, you can afford $200–$400 to acquire them. Most studios don’t track MAC at all, which means they can’t tell which marketing is profitable or how to allocate budget intelligently.
Calculating Your Fitness Studio MAC
Simple MAC Formula
Total monthly marketing spend ÷ New paying members acquired that month = MAC
Example: $2,500/month marketing × 20 new members = $125 MAC
If your average member generates $1,800 in their first year and your profit margin is 35%, you can afford $630 in acquisition cost. At $125 MAC, your economics are strong.
Channel-Level MAC
For smarter budget decisions, calculate MAC by channel:
- Google Ads spend ÷ members from Google Ads = Google MAC
- Meta Ads spend ÷ members from Meta Ads = Meta MAC
- Referral program cost ÷ members from referrals = Referral MAC
Referral MAC is almost always the lowest. Google Ads is often the most scalable. Instagram organic has near-zero direct cost but high time investment.
How to Track Member Acquisition Source
Ask every new member at intake: “How did you hear about us?” Log the answer. Your front desk or booking software (Mindbody, Pike13) should include a “referral source” field. This single question enables all attribution analysis.
Reducing MAC: The Highest-ROI Approaches
- Increase trial-to-member conversion rate: If MAC is $200 and you convert 30% of trials, improving conversion to 50% reduces effective MAC to $120.
- Build your referral program: Referred members cost a fraction of paid acquisition. Every loyal member is a potential low-MAC channel.
- Optimize your intro offer: A better intro offer (longer trial, more value) often converts at higher rates, reducing MAC.
Frequently Asked Questions
- What’s a typical member acquisition cost for a boutique fitness studio?
- Wide variation depending on market and marketing mix. Referral: $20–$50. Instagram organic: nearly zero in dollar terms (high time cost). Google Ads in competitive markets: $150–$400. Meta Ads: $80–$250. Studios that build strong referral cultures and Instagram communities often achieve blended MAC well below $100.
Next Steps
- Add “How did you hear about us?” to your intake process today.
- Calculate your current blended MAC — total marketing spend last month ÷ new paying members last month.
- Calculate your LTV — average monthly revenue per member × average months retained.
