Hotworx's FDD reports average gross sales of $330,476. That number is technically accurate. It's also meaningless without context — because gross sales is what comes in the door, not what stays in your pocket.
Between the $330K top line and your actual take-home sits a stack of expenses that most franchise overview sites either ignore or wave away with "varies by location." That's not analysis. That's a shrug.
Here's the actual model, built from disclosed franchise terms, industry benchmarks, and publicly available operating data. We run it at three scenarios: best case, base case, and stressed. If you're modeling this investment, these are the numbers to pressure-test.
The Revenue Assumption
We use $330,476 as the base case annual revenue — the average disclosed in Hotworx's most recent Item 19 financial performance representation. Important caveats apply: this average may exclude newer studios still in ramp-up, and your specific market will vary. See our FDD analysis for the full discussion of what this number includes and excludes.
For modeling purposes:
- Best case: $420,000 (top-quartile estimate based on high-traffic markets)
- Base case: $330,476 (disclosed average)
- Stressed case: $240,000 (bottom-quartile estimate, also a reasonable Year 1 figure for many markets)
Fixed and Semi-Fixed Costs
Royalty Fee: 6% of Gross Sales
This is non-negotiable. Hotworx charges a 6% royalty on gross sales — not net, not collected revenue, gross.
| Scenario | Revenue | Royalty (6%) |
|---|---|---|
| Best | $420,000 | $25,200 |
| Base | $330,476 | $19,829 |
| Stressed | $240,000 | $14,400 |
Advertising Fund: 2% of Gross Sales
The brand advertising fund contribution is 2% of gross sales. This funds national and regional marketing — it does not cover your local marketing spend, which is a separate line item.
| Scenario | Revenue | Ad Fund (2%) |
|---|---|---|
| Best | $420,000 | $8,400 |
| Base | $330,476 | $6,610 |
| Stressed | $240,000 | $4,800 |
Rent
Hotworx studios typically occupy 1,500–2,500 square feet in strip centers or retail pads. Reported lease rates range from $2,500 to $7,000/month depending on market.
| Scenario | Monthly Rent | Annual Rent |
|---|---|---|
| Best (secondary market) | $3,000 | $36,000 |
| Base (mid-market) | $4,500 | $54,000 |
| Stressed (premium market) | $6,500 | $78,000 |
Rent is the single largest fixed cost and the hardest to change once committed. Your site selection process will define your economics more than almost any other decision.
Technology Fee
Hotworx charges a monthly technology fee for its app platform, booking system, and now TrainingTRAX AI coaching. Based on FDD disclosures, estimate $500–$800/month.
| Scenario | Monthly Tech Fee | Annual |
|---|---|---|
| All scenarios | $650 (midpoint) | $7,800 |
Variable and Operating Costs
Staffing
The Hotworx model runs lean — typically 2–3 full-time equivalent employees handling front desk, cleaning, sales, and member management. The 24-hour access model reduces the need for around-the-clock staffing, but operational hours still require coverage.
Based on Indeed salary data and Glassdoor reports, typical compensation runs $15–$22/hour for studio staff, with general managers at the higher end.
| Scenario | FTEs | Avg Hourly | Annual Labor + Taxes (15% burden) |
|---|---|---|---|
| Best (lean) | 2.0 | $17 | $81,328 |
| Base | 2.5 | $18 | $106,470 |
| Stressed (turnover) | 3.0 | $19 | $134,964 |
The stressed scenario reflects higher headcount from turnover churn — when you're perpetually training replacements, you're effectively overstaffed during transitions. Employee reviews on Glassdoor suggest turnover is a real operational challenge for many franchise owners.
Local Marketing
The 2% ad fund covers brand-level marketing. Your local customer acquisition — Google Ads, local SEO, social media, community events, grand opening spend — is on you.
| Scenario | Monthly Local Marketing | Annual |
|---|---|---|
| Best (established) | $800 | $9,600 |
| Base | $1,200 | $14,400 |
| Stressed (ramp-up) | $2,000 | $24,000 |
Insurance
General liability, property, workers' compensation, and business interruption. Fitness studios carry specific risk profiles.
| Scenario | Annual Insurance |
|---|---|
| All scenarios (midpoint) | $10,000 |
Utilities
Infrared saunas are energy-intensive. A 2,000-square-foot studio running multiple sauna units draws significant electricity. Expect utility costs above standard retail.
| Scenario | Monthly Utilities | Annual |
|---|---|---|
| Best | $1,200 | $14,400 |
| Base | $1,500 | $18,000 |
| Stressed | $1,800 | $21,600 |
Equipment Maintenance and Replacement
Infrared sauna units, HVAC systems, flooring, and tech hardware all degrade. Budget for ongoing maintenance and a sinking fund for eventual equipment replacement.
| Scenario | Annual Maintenance/Reserve |
|---|---|
| Best | $6,000 |
| Base | $10,000 |
| Stressed | $15,000 |
Miscellaneous Operating
Cleaning supplies, towels/laundry service, software subscriptions beyond the franchise tech fee, accounting/bookkeeping, legal, point-of-sale supplies.
| Scenario | Annual Misc. |
|---|---|
| Best | $8,000 |
| Base | $12,000 |
| Stressed | $16,000 |

What These Numbers Tell You
The range is wide — and that's the point. The same franchise system produces dramatically different economics depending on three variables:
- Revenue — driven by your market's demographics, competition density, and your ability to acquire and retain members
- Rent — the largest fixed cost and the one most determined by geography
- Staffing efficiency — turnover is expensive, and the lean model only works if retention works
The base case yields roughly $23K in annual owner take-home after debt service. That's not a salary most people can live on — which means either your market needs to significantly outperform the average, or you need to plan for a multi-unit strategy where you spread fixed costs across 2–3 locations.
The stressed case is a cash burn. At $240K revenue in a premium-rent market with staffing churn, you're losing over $130K/year. This is not an unlikely scenario for a Year 1 studio in a competitive market.
The best case is genuinely attractive — $165K take-home is a strong small business income. But it requires above-average revenue, below-average rent, and efficient staffing simultaneously. That alignment doesn't happen by accident.
The Debt Service Assumption
We estimated $48,000/year in SBA debt service based on:
- Total investment of ~$500K (mid-range of Item 7)
- 80% financed via SBA 7(a) ($400K loan)
- 10-year term at 12% effective rate (current 2026 environment)
- Monthly payment of approximately $4,000
Your actual debt service will vary based on your total investment, down payment, interest rate, and loan term. The SBA financing guide on this site walks through the mechanics. If you're exploring SBA options at these investment levels, Lendesca publishes current rate data and lender comparisons that can help you model your specific capital stack.
How to Use This Model
This is a framework, not a forecast. Your job is to:
- Replace our rent assumption with an actual lease quote from your target market
- Replace our staffing assumption with local wage data and your operational plan
- Replace our revenue assumption with your own estimate based on market research and franchisee validation calls
- Stress-test the model at 70% of your base revenue assumption — if it still works, you have margin. If it doesn't, you need a different market or a different deal
The franchise system gives you a brand, a playbook, and a product. It does not give you a guaranteed outcome. The unit economics are your responsibility to validate before you sign.
