In 30 seconds: Simulate the annual membership cycle with realistic seasonality to project revenue and plan expenses with confidence. Deterministic calculation with auditable formulas. The result is indicative — adjust the assumptions to reflect your real operation.

A gym has theoretical 24-hour capacity, but reality is that 'peak hours' (6-8 AM and 6-9 PM) drive break-even. This calculator assumes monthly slot capacity; adjust to your model (membership, day pass, classes).

Methodology

Contribution per unit = Price − Variable cost

Max monthly capacity = Daily capacity × Operating days

Break-even occupancy (%) = (Fixed costs ÷ (Monthly capacity × Contribution per unit)) × 100

Break-even units = Fixed costs ÷ Contribution per unit

Expected profit = (Expected occupancy × Capacity × Contribution) − Fixed costs

Variables

Daily Capacity
Rooms, tables, covers, billable hours or other max operational units per day.
Price per Unit
Average price charged per unit sold (average daily rate, average ticket, billable hour).
Variable Cost per Unit
Direct cost tied to each unit sold (cleaning, food, commissions, materials).
Monthly Fixed Costs
Rent, base payroll, utilities, insurance, depreciation — costs that don't depend on occupancy.
Expected Occupancy (%)
Your realistic or historical average occupancy, to compare against break-even.
Operating Days per Month
Days the business actually bills (excludes weekly closures, maintenance).

Practical example

Boutique fitness in Polanco (Mexico City), CrossFit/functional HIIT style: 80 daily slots (5 classes of 16 people each), average ticket per class $700 (mix of $350 drop-in and 12-class packs at $750 each), variable cost $80/class (instructor prorated, water, towels, cleaning), 30 operable days, fixed costs $95,000 (prime location rent, quality equipment, full-time manager, marketing).

Per-class contribution margin: $700 − $80 = $620.

Monthly max capacity: 80 × 30 = 2,400 classes. Theoretical max revenue: $1,680,000.

Break-even occupancy: $95,000 ÷ ($620 × 2,400) = 6.4%, equal to 153 classes attended per month. Very low break-even thanks to the high margin.

At a realistic 55% occupancy (1,320 classes attended): profit = (1,320 × $620) − $95,000 = $818,400 − $95,000 = $723,400/month. However, 55% is aggressive for a boutique in a prime zone in its first year — the Fitness México 2024 benchmark reports 32-42% for operators with < 12 months, 50-65% for mature operators.

Operating recommendation: the right lever for boutique fitness is not raising price (elasticity is high above $750/class) or capacity (every extra slot adds instructor and maintenance). It's retention: every member who renews a 12-class pack is worth $8,400 vs the cost of acquiring a new member ($800-1,500). If your M3 retention drops below 60%, freeze ads and work on experience (level programs, WhatsApp community, monthly event).

Interpretation

Businesses with break-even occupancy below 30% have a robust financial structure — they can absorb slow seasons without risk.

Break-even occupancy between 30-50% is healthy but demands attention to seasonality.

Break-even occupancy above 60% is fragile: any bad week turns the month into a loss.

If your break-even occupancy exceeds your expected occupancy, the business is doomed to lose money until you change price, variable cost or fixed costs.

Raising the average rate by 10% usually lowers break-even occupancy more than reducing variable cost by 10%, because the effect multiplies across all capacity.

Assumptions and limitations

  • Assumes constant rate and variable cost — doesn't model dynamic rates (yield management) or seasonal discounts.
  • Assumes capacity is truly sellable: doesn't discount rooms blocked by maintenance or tables by understaffing.
  • Does not include secondary revenue (restaurant consumption, add-on sales, tips) — for a full analysis, add them as extra contribution.
  • Uses flat operating days: if you have 7 weak days and 23 strong ones, the average can hide per-day viability issues.

When to use this calculator

  • Before opening a capacity-limited business (hotel, restaurant, gym, coworking, clinic) to validate viability.

  • When evaluating a capacity expansion: if current break-even occupancy is 50%, adding capacity without extra demand makes it worse.

  • Before lowering price to fill occupancy: check whether the new contribution per unit still covers fixed costs at the expected volume.

  • To defend a rent negotiation: if the requested increase takes break-even occupancy from 40% to 65%, you have a numerical argument.

  • When planning marketing investment: quantify how many additional units you need to sell for the spend to be recovered in incremental profit.

Common mistakes

  • Using list rate instead of the average rate actually charged (with discounts, OTAs, corporate contracts). Break-even ends up underestimated.

  • Forgetting hidden variable costs: card fees, OTA commissions, tips running through payroll, outsourced laundry.

  • Assuming 30 operating days when there's a fixed closing day — that cuts capacity 13% and raises break-even proportionally.

  • Not reviewing break-even when fixed costs rise. A 10% rent increase can push break-even occupancy up several points.

Industry use cases

Traditional gym

Monthly membership $400-1,200. Typical break-even 200-400 members. Watch the cohort: 30-50% don't attend regularly but keep paying (silent membership).

Boutique fitness (CrossFit, yoga)

Class $150-350 or membership $1,500-3,500. Class capacity 8-20. High per-class margin justifies a low break-even point.

Low-cost / 24h gym

Membership $200-500. High volume needed (1,000+ members) to amortize investment. Real capacity is limited at peak hours.

Personal training studio

1:1 session $400-1,500. Very limited capacity. Model closer to professional services than a traditional gym.

Methodology and assumptions

How results are calculated, what we assume when modeling, and where the method loses precision.

Formula

Break-even occupancy % = Fixed costs ÷ (Monthly capacity × (Price − Variable cost)) × 100

Assumptions

  • ADR (average daily rate) constant within the analysed horizon.
  • Fixed costs cover base staffing, rent, utilities and operating depreciation.
  • Per-night contribution margin (Price − Variable cost) reflects real variable cost per room.

Applicability limits

  • Does not model dynamic pricing (revenue management): use the median actual ADR.
  • Punctual events (conventions, peak season) need manual period adjustment.
  • For full-service hospitality include F&B and other revenue streams separately.

How to project gym revenue

Gym revenue is made up of three streams that behave differently: the recurring membership base, the auxiliary income from personal training and drop-in classes, and ancillary sales (supplements, retail, corporate wellness). Each has different price elasticity, seasonality and margin. Projecting only the base MRR — as most Excel templates do — leaves 25%-40% of revenue outside the model and distorts cost planning.

Gym base MRR = Active members × ARPM (average revenue per member per month)

The trick is in "active members". It is not the total enrolled base: it is those who paid the monthly fee this month. The gap between enrolled and active memberships at an average Mexican gym runs 18%-24% — almost a quarter of your theoretical base is not paying.

ARPM: the metric that replaces list price

ARPM (average revenue per member) integrates real monthly payments, not list price, and is below the headline rate. Reasons: freezes, corporate discounts, family plans, partial dropout (members who pay one month, miss two, come back on the fourth), failed card charges. A gym that advertises USD 70/month typically operates with ARPM of USD 56-62.

ARPM = Total monthly membership revenue ÷ Active members for the month

Example: urban boutique gym with 280 active members, list price USD 105, actual month revenue USD 27,200. ARPM = USD 97 — 8% below the headline. Use historical ARPM, not the new price, to project.

Monthly churn: the metric that explains why March always hurts

Monthly churn = Cancellations in the month ÷ Active members at the start of the month × 100

IHRSA (International Health, Racquet & Sportsclub Association) benchmark: healthy monthly churn big-box gym 4%-6%, boutique 2.5%-4%. Translated to annual, median US attrition rate is 28.6%. A Mexican gym with 7% monthly churn loses half its base every 10 months.

The compound effect is what surprises new owners. Gym with 300 members and 7% churn: month 1 loses 21, month 2 loses 19 (on 279), month 3 loses 18. After 6 months without acquisition, the base falls to ~197. If monthly acquisition equals churn (21-22 new), the base stagnates; if lower, it bleeds out slowly. Most owners do not know their real churn and assume the base maintains itself.

Member LTV: what each enrollment is actually worth

LTV = (ARPM × gross margin) ÷ Monthly churn

Example: boutique studio with ARPM USD 97, gross margin 62% (after prorated rent, coach fees and amenities), 4% monthly churn. LTV = (97 × 0.62) ÷ 0.04 = USD 1,504. If your CAC (cost of acquisition per member) is USD 224 — ads + first-session promo + prorated sales staff — your LTV/CAC ratio is 6.7x. Any ratio above 3x is healthy; 1x-3x signals inefficient acquisition; below 1x is unsustainable.

How to calculate your 12-month projection step by step

  1. Capture initial base. Active members month 0, current ARPM, monthly ancillary income (PT + retail + drop-in classes).
  2. Estimate real monthly churn. Calculate on the last 6 months. Do not use the neighbor gym owner's number — your churn depends on your onboarding program, price mix and group-class capacity.
  3. Estimate monthly acquisition. Net new enrollments (not gross). Pro tip: 30%-40% of January "enrollments" cancel in the first 45 days; use net new.
  4. Apply seasonality. January +35% acquisition, February-March normal, April-June -5% to -10%, July-August -15% (vacation), September +20% (back-to-school), October-November normal, December -20%.
  5. Project monthly compounding. Base(t+1) = Base(t) + acquisition(t) − churn(t)% × Base(t). Carry month by month.
  6. Sum streams. Membership MRR + PT revenue (compute as % of active members who take PT × average ticket) + retail sales + corporate.
  7. Model scenarios. Optimistic (churn −1pp, acquisition +15%), realistic (historical), pessimistic (churn +2pp, acquisition −10%).

Revenue mix: not everything is membership

Average US gym — IHRSA 2025 benchmark: 68% memberships, 14% personal training, 8% retail/supplements, 6% drop-in classes, 4% corporate wellness. Typical boutique CrossFit: 80% memberships, 12% retail, 8% events and nutrition coaching. The owner who ignores PT leaves 15%-20% of revenue on the table; the one who pushes PT above 25% of total cannibalizes retention (members who only take PT without membership eventually churn).

Revenue per square meter: the benchmark no one watches

It is the toughest operational KPI to compare across models. Conventional big-box: USD 50-82 / m² / month. Boutique studio LatAm: USD 130-280 / m² / month. Smart Fit franchises in LatAm optimize the big-box with aggressive revenue per m²: large spaces, low price (USD 29-70/month), very high member density per m² (7-12 vs 3-5 in traditional conventional). The boutique competes on margin, not on volume.

Real LatAm seasonality

The "January fills the gym, March empties it" myth is partially true but oversimplified. Virtuagym and Mindbody LatAm 2024-2025 data: January +30%-40% acquisition vs baseline, 90-day retention of the January cohort is 52%-58% (worse than other months); September +15%-22% acquisition with 90-day retention of 68%-72% (best cohort of the year). July-August drop acquisition 15%-25% but lift PT through summer classes. December drops 20%-30% across the board. A useful model does not just adjust acquisition: it adjusts cohort retention by entry month.

2025 benchmarks by segment

  • Conventional / big-box LatAm (Smart Fit, Sports World, Bodytech). 500-2,500 members per unit, ARPM USD 32-56, monthly churn 5%-7%, annual revenue per unit USD 470K-2.05M.
  • Boutique studios (CrossFit boxes, HIIT, Pilates, yoga). 80-220 members, ARPM USD 88-165, churn 3%-4.5%, annual revenue USD 175K-470K.
  • Independent neighborhood gyms. 150-400 members, ARPM USD 41-65, churn 6%-8%, annual revenue USD 88K-265K.

Break-even: how many members you need

Break-even members = Monthly fixed costs ÷ (ARPM × contribution margin)

Example urban boutique HIIT: rent USD 2,820 + coach payroll USD 4,410 + admin USD 880 + software/marketing USD 705 + utilities USD 470 = USD 9,290 monthly fixed spend. ARPM USD 115, contribution margin 72% (after variable cost per delivered class). Break-even = 9,290 ÷ (115 × 0.72) = 112 active members. Any base below operates at a loss; above that, each additional member contributes USD 83 of direct margin.

Mistakes that kill margin

  • Unlimited freezes. A frozen member does not pay but occupies a locker and stays on the system. A policy without a cap turns 15%-20% of the base into zombies. Apply a maximum of 60 days per year with a symbolic monthly fee.
  • Empty group classes. A class with 2 people costs the same as one with 15. Monitor class utilization (attendees ÷ capacity). If it drops below 45% over 60 days, consolidate.
  • Unstructured PT. Selling single sessions without prepaid packages kills coach LTV and member repurchase. Packages of 10-20 sessions with expiration.
  • Fixed price for a year without review. Inflation in Mexico 2024-2025 was 4.5%-6%. A gym that does not raise ARPM annually compresses margin ~2% each year.
  • Not measuring churn. Most independent gym owners do not know their exact monthly churn. Without that number, every projection is fiction.

Excel template vs interactive model

The downloadable template solves a static calculation of current MRR and fails in projection. It does not model compound churn, does not adjust for cohort seasonality, does not separate streams, does not simulate the impact of a 2-point churn drop on 12-month ARR. An interactive model that carries churn and acquisition month by month, compares three scenarios and shows the moving break-even is the difference between having a number to show the banker and having real visibility on whether your gym is growing, holding or bleeding out.

Illustrative case

Composite case for instructional purposes: combines sector dynamics with realistic figures. Names are fictional and do not represent a specific company.

Volta Studio is a 185 m² boutique HIIT in Polanco, Mexico City, opened in February 2023 by Daniela Pérez, a former marketing director at a multinational. Installed capacity 22 per class, 7 classes/day Monday to Friday, 4 Saturday, 2 Sunday. List price $2,200/month unlimited. At 18 months of operation Daniela could not cross break-even. 168 active members, monthly revenue $278,000, fixed spend $310,000, monthly operating loss $32,000.

The diagnosis came from running the full exercise in Simúlalo. Real ARPM: $1,655 (headline $2,200) — Daniela was giving untracked discounts, had not reviewed prices in 18 months, and 22 members were frozen for free as indefinite courtesy. Monthly churn: 6.8% (boutique benchmark should be 3%-4%). Monthly net acquisition: 17 members. With compounding, the base was stuck. Class utilization: 48% average (capacity 154 slots/day × 5 days, average attendance 75). PT revenue: 3% of total — Daniela had not packaged PT nor trained coaches on sales.

Three interventions Q3 2024: (1) freeze audit, symbolic monthly fee $150, 60-day annual cap — released 22 slots and recovered $3,300 in phantom MRR; (2) price review with increase to $2,500 only for new members (legacy pricing for the existing base), plus a 10-session prepaid PT package at $3,500; (3) 30-day onboarding program with dedicated check-in, which historically corresponds to 40% of annual churn.

Results 6 months later (Q1 2025): 214 active members, ARPM $1,820, monthly churn 4.1%, monthly net acquisition 22 (January +35%). Membership revenue $389,500. Packaged PT added $62,000 extra, allied supplement retail $18,000. Total revenue $469,500 vs fixed spend $315,000 (up $5K for an additional coach). Monthly operating margin +$154,500. Re-computed break-even: 138 members. LTV rose from $15,400 to $27,800 through the combined effect of lower churn and higher ARPM.

Nine months earlier the same operation was losing $32,000/month with 168 members. Q1 2025 closed with a positive margin of $154,500/month and 214 members — 27% more base, a 480% swing in margin. None of the three interventions was new-traffic acquisition: they were auditing freezes, packaging PT and sealing the first-30-days onboarding where 40% of annual churn was happening.

Frequently asked questions

1How do you calculate gym revenue?
Revenue = (active members × ARPM) + personal training + retail + drop-in + corporate. Base MRR uses real ARPM (not list price), not total enrolled. Project 12 months applying compound monthly churn and acquisition with seasonality (January +35%, September +20%, December −25%). LTV per member = (ARPM × gross margin) ÷ monthly churn.
2What is the average MRR of a gym?
It depends on the segment. Boutique studio MX/CO: 120-220 active members × ARPM $1,650-$2,500 = $200K-$550K/month. Big-box Smart Fit / Sports World: 800-2,500 members × ARPM $550-$950 = $450K-$2.3M/month. Independent neighborhood gym: 150-400 members × ARPM $700-$1,100 = $110K-$440K/month.
3What is the churn rate at a gym?
Monthly churn is the percentage of active members who cancel that month. Formula: monthly cancellations ÷ members at the start of the month × 100. It is the most important metric in the model because it operates by compounding: a gym with 300 members and 7% monthly churn loses half its base in ~10 months without acquiring.
4What is a healthy churn rate for a gym?
IHRSA 2024 benchmark: big-box and conventional 4%-6% monthly, boutique 2.5%-4% monthly. Annualized, median US attrition is 28.6%. Above 7% monthly the gym lives in survival mode — all acquisition goes to replace churn instead of growing the base.
5How is member LTV calculated?
LTV = (ARPM × gross margin) ÷ monthly churn. Boutique example with ARPM $1,650, margin 62%, 4% monthly churn: LTV = (1,650 × 0.62) ÷ 0.04 = $25,575. Compare with your CAC (cost of acquisition per member); an LTV/CAC ratio above 3x is healthy.
6How many members do I need for my gym to be profitable?
Break-even members = monthly fixed costs ÷ (ARPM × contribution margin). Boutique HIIT example with $158,000 fixed spend, ARPM $1,950, margin 72%: break-even at 113 active members. Big-box with the same $158,000 but ARPM $750 and 65% margin: break-even at 324 members.
7How do you increase member retention?
The #1 lever is the first-30-days onboarding: members who get PT in the first 4 weeks stay 40% longer (Virtuagym 2024). Other validated interventions: introductory group classes with a dedicated coach, 60- and 90-day follow-up check-ins, community (events, challenges, WhatsApp), limited freezes with a symbolic fee instead of free.
8What percentage of revenue should come from personal training?
IHRSA 2024 benchmark: 12%-18% of total revenue in big-box, 8%-14% in pure boutique group classes, 20%-28% in hybrid boutique that packages PT. Below 8% you leave money on the table; above 30% you cannibalize retention because PT-only members tend to churn after 6-9 months.
9How much does it cost to open a profitable gym?
Boutique studio MX/CO (120-200 m²): initial investment USD $90K-$180K (equipment, build-out, software, 6 months of operation). Smart Fit franchise LatAm: USD $600K-$1.2M. Independent conventional gym 400-700 m²: USD $250K-$500K. Time to break-even: boutique 9-14 months, big-box 18-30 months. Close to 35% of new gyms fail to reach year two (IHRSA).
