Model your gym or fitness studio's membership profitability, including churn-driven member lifetime value, LTV:CAC ratio, and a full cost breakdown.

Mathematical Audit

How Gym & Fitness Studio Membership Profitability Is Calculated

The calculator builds monthly revenue from membership dues and ancillary income (personal training, classes, retail), subtracts total operating costs, and uses your monthly churn rate to project average member lifetime and lifetime value (LTV) against your acquisition cost (CAC).

Membership Dues Revenue = Member Count × Average Monthly Dues
Ancillary Revenue = Member Count × Ancillary Revenue per Member
Total Monthly Revenue = Membership Dues Revenue + Ancillary Revenue
Total Monthly Costs = Rent + Payroll + Equipment Depreciation + Utilities & Insurance + Marketing + Other Overhead
Net Profit = Total Monthly Revenue − Total Monthly Costs
Profit Margin % = Net Profit ÷ Total Monthly Revenue × 100
Average Member Lifetime (months) = 1 ÷ Monthly Churn Rate
Member Lifetime Value (LTV) = (Avg Monthly Dues + Ancillary Revenue per Member) × Average Member Lifetime
Customer Acquisition Cost (CAC) = Marketing Spend ÷ New Members per Month
LTV:CAC Ratio = LTV ÷ CAC

Monthly churn rate is the single biggest lever in this model — even small reductions compound into a much longer average member lifetime and a much higher LTV, since lifetime in months is the mathematical inverse of the churn rate. Boutique studios with stronger community and coaching typically retain members longer (and see higher LTV) than big-box gyms with weaker onboarding.

Real-World Scenario Example

"A boutique studio with 600 members paying $69/month in dues plus $20/month in ancillary revenue per member, a 4% monthly churn rate, 35 new members signed up per month on $2,800 monthly marketing spend, $9,000 rent, $25,000 payroll, $2,500 equipment depreciation, $3,500 utilities/insurance, and $1,800 other overhead."

Inputs

memberCount:600
avgMonthlyDues:69
ancillaryRevenuePerMember:20
monthlyChurnRate:4
newMembersPerMonth:35
marketingSpendMonthly:2800

Result

Total monthly revenue of $53,400 against $44,600 in costs leaves a net profit of $8,800/month (16.5% margin). Average member lifetime is 25 months, giving an LTV of $2,225 against a CAC of $80 — a strong LTV:CAC ratio of about 27.8:1.

Actual membership pricing, churn rates, payroll costs, and profit margins vary significantly by gym type, market, and location — consult a fitness-business accountant or consultant before making operating decisions.
