A signup is not a retained member-month
Trials, signed future contracts, failed charges, freezes and cancellations can inflate a gross enrollment count without producing the earned recurring revenue used by the model.
The Michigan studio reference earns about $5,037 per mature month at 280 assumed paid active members. At 240, it loses about $506. A Detroit storefront advertises $3,500 monthly base rent plus NNN and names fitness studio as a potential use, but city approval, fit-out and total occupancy remain unconfirmed.

State benchmarks: May / July 2025 · Page prepared September 13, 2026
The Michigan reference crosses its modeled mature-month break-even at about 244 paid active members, assuming $149 collected net yield each. Its $5,037 EBIT at 280 members becomes about -$506 at 240 with staffing and fixed costs unchanged. A named 2,000-square-foot Detroit storefront is advertised as a potential fitness-studio site, and an operating Detroit yoga studio publishes an unlimited tier. They make the lease and price tests concrete but do not demonstrate a new studio's approved use, class capacity or collected revenue.
| Input | Published evidence | Planning use and remaining scope |
|---|---|---|
| Listed membership | Midtown Yoga in Detroit advertises a recurring unlimited-month membership for $130. It is a hot-yoga offer, with a format and timetable that may differ from this proposed group studio. Sources: Midtown Yoga Detroit: prices | The model's $149 is an achieved net yield, not a posted local price. Test the actual mix of memberships, classes, discounts, freezes and collected payments; the $130 listing does not establish what this studio could earn. |
| Premises | A broker advertises 2,000 square feet at 1732 W Bethune St for $21 per square foot per year, or $3,500 monthly base, on NNN terms. Fitness studio is listed among potential uses, explicitly subject to city approval; additional rent is on request. Sources: Encore Real Estate listing: 1732 W Bethune St | The base leaves $4,000 within the $7,500 reference occupancy allowance for NNN and other charges. Obtain the full lease, approved use, class layout and fit-out bids. The listing is not a completed studio quote. |
| Use and opening | Detroit's new-business guide directs applicants to check zoning, construction or change-of-occupancy requirements, inspections and the applicable occupancy or acceptance certificate. Its building-permit guidance says a change of use can require a Certificate of Occupancy. Sources: City of Detroit: quick start guide for new businesses · City of Detroit: building permits | Resolve the legal use of this exact storefront and its building scope with the city before budgeting an opening date. Neither city page prices this project's full work and approval. |
| Member threshold | The public operator tier is $130, while the cited lease gives only base rent and unpriced NNN. Both differ in scope from the model's $149 achieved yield and $7,500 complete occupancy reference. Sources: Midtown Yoga Detroit: prices · Encore Real Estate listing: 1732 W Bethune St | Check a 240-member month in the complete calculator, then replace yield and occupancy together with supported numbers. A low base rent alone cannot defend the $5,037 reference margin. |
Use the complete calculator below to test 240 versus 280 paid active members and change achieved yield and complete occupancy together. The Detroit listing and competing tier are decision evidence, not substituted defaults. Opening cash, reserve and the 60-month schedule update in the same calculator.

The mature reference month has a surplus. 280 assumed paid active member-months per month produce $5,037.19 EBIT and $6,820.52 cash after the modeled maintenance investment. Both include paid work and exclude financing, income taxes and owner distributions. The $326,045.61 opening-funding scenario is separate; a reserve cannot remove an ongoing operating loss.
The May 2025 Michigan Exercise Trainers and Group Fitness Instructors median is $21.88 per hour. Applied to the page’s full paid roster, state occupation benchmarks produce $16,979.08 monthly payroll, $924.68 lower than the same national-wage roster ($17,903.76), including the assumed 18% employer allowance. BLS state May 2025, SOC 39-9031, H_MEDIAN, row 16051. Use this comparison to obtain role-specific hiring terms and employer charges; it does not price rent or demonstrate customer demand.
With the same realized yield, costs and paid roster, 244 full billable member-months in a modeled month produce $48.67 EBIT; 243 leave −$89.90 EBIT. This tests earned full member-months, not leads, trials, signed future contracts or frozen memberships. The separate mature cash-after-maintenance boundary is 231 full billable member-months per month, before financing and income taxes; it does not establish launch payback.
Rounded break-even values elsewhere on this page are estimates. The conditional whole-unit tests here use the full unrounded inputs. EBITDA excludes depreciation and maintenance investment; EBIT includes depreciation; cash after maintenance deducts maintenance investment and is not owner income.
The assumed timetable has 45 classes a week with 16 places each: 3,120 monthly reservation spots on a 52-week annual average. At 8.5 reservations per member-month, 280 billable members need 2,380 spots; the 350-member planning ceiling needs 2,975. Paid instructor coverage is 243.75 hours per month, equivalent to 1.25 hours per scheduled class; operations and member service are paid separately. Check preferred-time access, safe room capacity, setup, reset and substitution. Track billable members by cohort: replace cancellations, freezes and failed collections before counting net growth. The $149 is a realized earned yield; class-pack or drop-in revenue already included in it must not be added again. The post-ramp flat membership line assumes replacement succeeds; it is not evidence of zero churn.
| Change from reference | Monthly EBIT | Held-constant scope |
|---|---|---|
| 20% fewer paid activity units | −$2,722.73 | Assumed activity falls; yield and the paid roster remain unchanged. |
| 25% higher full occupancy cost | $3,162.19 | Complete occupancy changes; refundable opening deposits also change in the full calculator. |
| 10% higher wage rates | $3,339.28 | Every paid role changes together; hours and the employer allowance remain unchanged. |
20% fewer paid activity units gives the lowest EBIT among these three tests: −$2,722.73. These differently sized tests are sensitivities, not a probability range or an exhaustive risk ranking. A result reverses when realized contribution no longer covers the stated paid costs; validate the selling unit and every binding resource before accepting extra volume.
Next validation action: Keep the named city’s rule, list-price and asking-rent examples separate from the retained reference inputs. A cheaper base rent or competitor tier becomes a model input only after its full scope matches this studio. Observed wage and population records keep their source periods; the rent, selling yield, opening allowances, employer load and sales ramp remain disclosed assumptions unless a separately scoped observation says otherwise.

| Evidence family | Published basis | What to confirm locally |
|---|---|---|
| Opening costs | Published planning inputs — replace with local quotes | premises scope, fitout, equipment, installation freight tax, deposits, preopening training, opening inventory, contingency |
| Operating costs | Published planning inputs — replace with local quotes | occupancy, utilities, insurance, materials, payment fees, marketing, software administration, maintenance |
| Paid labor and employer costs | State wage benchmark used — confirm employer costs | paid roster, wages, wage floor overtime, employer taxes, benefits leave, workers compensation, owner role |
| Revenue and collections | Published planning inputs — validate price and demand locally | realized price mix, demand volume, capacity, industry cross check, launch ramp, seasonality, collections |
| Permissions and fees | Confirm for the selected address | activity address jurisdiction, initial fees, recurring fees |
National equipment prices can support the plan where configuration, delivery and taxes match the intended purchase. Confirm rent, selling prices, demand and permissions for the actual location instead of applying a generic state adjustment.
The Census estimate for Michigan is 10,127,884 people. It grew by 27,922 between July 2024 and July 2025 (+0.28%). This statewide movement cannot identify a viable retained membership, usable class-access pattern or realized member value.
Using the same paid roster, Michigan occupational wages produce $16,979 of monthly loaded payroll. That is −5.16% relative to the identical roster priced with national occupation medians ($17,904). Only wage benchmarks change in this comparison; it does not measure a state’s overall business attractiveness.

Leased boutique group fitness studio with one primary class room, a defined weekly timetable, paid instructors, paid studio coordination and recurring monthly memberships. A 2,500-square-foot boutique group fitness studio delivering a defined weekly class timetable through paid instructors, studio operations and member-services coverage.
The authored timetable provides 3,120 bookable class spots per month from 45 whole weekly classes and 16 spots per class. At 8.5 reservations per member-month, the arithmetic supports 367 whole member-months before time-slot preference; the shared model uses a lower 350-member ceiling. Both are planning assumptions rather than observed demand or approved occupancy. Peak-time access, safe layout, equipment, instructor coverage, opening and closing work, cleaning, cancellations and the actual member visit pattern can reduce usable capacity.

Base wages total $14,389 per month. An authored 18% allowance for employer costs adds $2,590, giving $16,979 of loaded payroll. The allowance is a planning shortcut; it is not a state-specific payroll tax calculation or benefits quote for Michigan.
Exercise Trainers and Group Fitness Instructors, First-Line Supervisors of Personal Service Workers and Customer Service Representatives are broad May 2025 occupational wage benchmarks. They do not establish studio-specific hiring quotes, qualifications, lawful scheduling, employer obligations or compensation terms. The model pays all class instruction, operations and member-services hours; it does not use unpaid owner work to create capacity. Every operating role is paid, including management or supervision. If the owner performs a modeled role, their compensation occupies that role once; no additional owner draw is included in operating profit.
The middle 50% wage interval describes the occupation’s observed wage distribution. It is not a confidence interval for this business’s total payroll. Allocate the aggregate hours across an actual roster and check wage rules, overtime, leave and employer obligations for the chosen location.
| Use of funds | Cash paid |
|---|---|
| Design, lease review, permits and professional allowance | $12,000 |
| Tenant improvements, acoustic treatment, HVAC and electrical allowance | $80,000 |
| Resilient flooring, mirrors, storage and signage | $30,000 |
| Functional training equipment package allowance | $45,000 |
| Audio, access control, POS and security setup | $12,000 |
| Furniture, cleaning equipment and opening supplies | $8,000 |

| Refundable deposit (two months of occupancy) | $15,000 |
| Paid pre-opening training | $2,006 |
| Total payments before opening | $232,006 |
The equipment and premises allowances are the same in all 50 states for this operating format. They are a comparison baseline and must be replaced with local scopes and quotes. Training uses 80 aggregate paid hours at the modeled team’s weighted loaded rate. The refundable deposit is cash tied up, not an operating expense.
The cash schedule tests 60 months, with sales ramping through 40%, 55%, 70%, 82%, 90%, 96%, 100% of the volume assumption. Full payroll and fixed costs begin in month one. The reserve covers the deepest cumulative operating deficit plus the stated buffer. A buffer is retained cash, not spending and not part of project payback twice.
The reference assumes member charges are collected without receivable delay for the month in which access is earned. Prepaid terms, deferred service, failed payments, refunds, credits, freezes, chargebacks and taxes collected for government need their own billing and revenue schedule. Asset purchases are depreciated over 60 months for this scenario. No sale or deposit recovery is assumed at the end.
At the assumed 280 paid active member-months per month, the reference scenario produces $5,037 of mature monthly EBIT, a 12.1% operating margin. Its continuous EBIT threshold is approximately 243.6 paid active member-months per month for EBIT break-even. This result depends on unverified selling price, demand and premises inputs.
| Measure | Monthly amount |

| Revenue | $41,720 |
| Variable operating costs | $2,920 |
| Loaded payroll, including management | $16,979 |

| Depreciation | $2,783 |
| Operating profit (EBIT) | $5,037 |
| Maintenance capital expenditure | $1,000 |
| Mature project cash flow | $6,821 |
EBIT break-even revenue is $36,304 per month: $33,762 of fixed costs plus depreciation divided by a 93% contribution margin. At $149.00 per paid active member-month, that is approximately 243.6 paid active member-months per month and 69.6% of the stated capacity.
| Measure | Months 1–12 | Mature month |
|---|---|---|
| Revenue | $430,968 | $41,720 |
| Operating profit (EBIT) | -$4,349 | $5,037 |
| Project cash flow | $17,051 | $6,821 |
Project payback occurs in month 44 in this reference schedule. It measures recovery of actual pre-opening payments from cumulative project cash, with no financing or owner distributions. It does not measure cash paid back to an owner.
Trials, signed future contracts, failed charges, freezes and cancellations can inflate a gross enrollment count without producing the earned recurring revenue used by the model.
Full preferred-time classes and empty off-peak classes can produce a reasonable average while retained members cannot book the service they value.
