What Numbers Tell You If You're Actually Making Money?
You're checking if the model is profitable: EBITDA must trend positive year-over-year and breakeven should be reached in Year 3 to confirm sustainable unit economics. Revenue growth from $840,000 in Year 1 to Year 3 validates product-market fit, while gross margin expansion should occur as diagnostic lab fees and CGM device costs decline. Compare these signals to operating costs using What Operating Costs Weight Loss Centers Incur? and track revenue per active client and referral conversion rate for scaling evidence.
Profit signals to watch

Revenue: $840,000 → Year 3
Gross margin expansion after diagnostics and CGM
Breakeven achieved in Year 3
Which KPI Predicts Cash Flow Problems Early?
Cash runway versus minimum cash is the single earliest warning for cash flow trouble, so watch it every week and act fast. Compare runway to the $2,671,000 minimum cash and track monthly net cash burn against fixed costs like $15,000 rent, plus accounts receivable aging from corporate partners and referral networks. Monitor sales conversion velocity for high-ticket $8,000-$12,000 annual subscriptions and flag slow conversions immediately. For setup steps tied to these metrics, see How to Start a Weight Loss Center?
Early Cash-Problem Signals
Cash runway vs minimum cash ($2,671,000)
Monthly net cash burn vs $15,000 rent
Accounts receivable aging from partners
Sales conversion velocity for $8,000-$12,000 subs
Which KPI Shows If Marketing Is Paying Off?
Customer Acquisition Cost (CAC) versus first-year revenue per client is the primary KPI to show if marketing pays off, and it should be tracked alongside referral commission rates and corporate lead conversion to see real ROI - read How Profitable is a Weight Loss Center? for context. Also watch marketing spend as a percent of revenue from Year 1 to Year 5 to spot efficiency gains. Track CAC by channel (corporate, referrals, digital) and compare to first-year revenue to judge payback. Finally, include referral commissions in CAC and monitor corporate partner lead-to-paid conversion for recurring subscriptions.
What KPI Do Most New Owners Ignore Until It's Too Late?
You're often focused on signups, but the thing that kills weight loss center KPIs fastest is cash planning-so read on. Track the minimum cash threshold of $2,671,000, client lifetime value versus program delivery cost and churn, deferred revenue timing for 12-month subscriptions, and headcount-driven wage costs before hiring more FTEs.

LTV vs cost: compare lifetime value to delivery cost
Revenue per Active Client measures the billed subscription dollars collected from each enrolled client in a given period. It shows whether your program is realizing target price points and helps spot margin leakage when diagnostics or device fees hide inside revenue.
Advantages
Shows price realization versus target $8,000-$12,000
Highlights revenue differences by referral source for ROI
Detects margin leakage when diagnostics and device fees rise
Disadvantages
Can be skewed by one-time diagnostic or device revenue
Hides variance across client segments without cohort split
Misleads if deferred revenue timing isn't aligned
Industry Benchmarks
Use the program's own target price range as the primary benchmark: $8,000-$12,000 per annual subscription. Compare realized revenue to Year 1 reported revenue of $840,000 and Year 3 $5,320,000 to validate whether per-client pricing and volume align with growth milestones.
How To Improve
Separate diagnostics and CGM device fees from subscription revenue
Price-pack upgrades (maintenance/advanced modules) to lift ARPC
Attribute revenue to referral channels and renegotiate low-converting partners
How To Calculate
Revenue per Active Client = Total billed subscription dollars collected in period / Number of active enrolled clients in same period
Example of Calculation
Revenue per Active Client = $840,000 / 105 = $8,000
Tips and Trics
Report subscription and diagnostic/device revenue separately each month
Segment by referral source: medical partners, corporate, direct digital
Track first-year revenue per client versus CAC for payback analysis
Adjust pricing or add modules if realized ARPC sits below $8,000
KPI 2: Customer Acquisition Cost (CAC)
Definition
Customer Acquisition Cost (CAC)
CAC measures the average marketing and referral cost to acquire one paid client. It shows if your marketing and referral channels buy profitable, long‑term subscriptions versus just volume.
Advantages
Shows payback versus first‑year revenue per client
Segments channels to lower cost per paid enrollment
Helps set sustainable marketing budgets tied to subscription prices
Disadvantages
Can hide declining quality if only total CAC tracked
Ignores post‑sale costs (diagnostics, CGM devices) that affect unit profitability
Industry Benchmarks
For subscription health programs, compare CAC to first‑year revenue per client. Target price points for this model are $8,000-$12,000 per client in Year 1, so a CAC under $8,000 preserves full payback within year one; CAC nearer to $12,000 requires strong retention or LTV to be viable.
How To Improve
Include referral commissions and marketing spend in monthly CAC
Segment CAC by channel: corporate, referrals, direct digital
Optimize referral conversion rate from medical partners to reduce paid acquisition costs
How To Calculate
Customer Acquisition Cost (CAC) = (Total marketing spend + Referral commissions) ÷ Number of new paid clients
Compare CAC each month to first‑year revenue per client $8,000-$12,000
Track CAC trend as marketing percent of revenue falls between Year 1 and Year 5
Break out CAC by channel and stop spend on channels with low referral conversion
Include deferred revenue timing and referral payables when forecasting CAC payback
KPI 3: Client Retention and Cohort Retention Rate
Definition
Client Retention and Cohort Retention Rate measure the share of enrolled clients who stay active through the mandatory 12‑month program and beyond. These metrics show whether your weight loss center keeps clients long enough to deliver outcomes, drive maintenance revenue starting in Year 2, and hit revenue milestones like $840,000 in Year 1 and $5,320,000 in Year 3.
Advantages
Shows program effectiveness tied to 12‑month outcomes
Predicts post‑program maintenance revenue from Year 2 onward
Helps prioritize retention over one‑time signups to protect LTV
Disadvantages
Lagging metric - shows problems after they happen
Can hide quality issues if you only track overall retention
Doesn't reflect biometric improvements or module completion directly
Industry Benchmarks
Track monthly cohort retention across the 12‑month program and then measure maintenance uptake in Year 2. Use retention trends to test the revenue path from $840,000 (Year 1) toward $5,320,000 (Year 3); improving cohort retention materially explains margin and LTV gains.
How To Improve
Tie retention to biometric milestones and module completion
Segment cohorts by referral source to boost high‑quality enrollments
Offer low‑friction maintenance options to convert post‑program
How To Calculate
Client Retention Rate = (Number of clients active at period end ÷ Number of clients at period start) × 100
Example of Calculation
Client Retention Rate = (150 ÷ 200) × 100 = 75%
Tips and Trics
Measure retention monthly per cohort, not just overall
Correlate retention with biometric improvements and completion rates
Attribute retention to referral source to optimize CAC tradeoffs
Forecast Year‑2 maintenance revenue from cohort retention curves
KPI 4: Gross Margin (%)
Definition
Gross Margin (%) measures the share of revenue left after direct program costs-primarily diagnostic lab fees and CGM device costs-are paid. It shows whether your pricing covers clinical delivery and whether margins improve as device and diagnostic spend fall over time.
Advantages
Separates direct care cost from operating overhead
Signals pricing adequacy across $8,000-$12,000 subscriptions
Helps spot high-cost clients needing alternate care
Disadvantages
Misleading if diagnostics are billed pass-through variably
Ignores indirect costs like clinician admin time
Sensitive to one-off device purchases and timing
Industry Benchmarks
For subscription-based medical programs, a healthy gross margin typically sits above 50% when diagnostics and devices are managed efficiently. Higher-margin telehealth and software-led programs can reach 60-80%, while device-heavy clinic models often fall in the 30-50% range.
How To Improve
Negotiate lab and CGM pricing to lower unit COGS
Shift care to software/remote coaching to raise leverage
Bundle diagnostics or pass-through fees transparently
Track diagnostics and CGM spend per client, monthly
Report gross margin by referral source and cohort
Model margin impact of shifting diagnostics to partners
Use software to reduce clinician time per client
KPI 5: Cash Runway and Minimum Cash Position
Definition
Cash Runway and Minimum Cash Position measures how many months the weight loss center can operate before running out of usable cash, and the minimum cash buffer of $2,671,000 management needs to hold to avoid a liquidity crisis. It shows whether deferred revenue from 12‑month subscriptions, capex timing like the $75,000 RMR purchase, and monthly burn align with targets such as the critical month Jan-28.
Advantages
Detects liquidity gaps before the critical month Jan-28
Aligns hiring and capex to confirmed revenue milestones
Integrates deferred revenue timing from 12‑month subscriptions
Disadvantages
Overstated if accounts receivable from partners are delayed
Hidden costs like diagnostic lab fees and CGM device costs can shorten runway
Depends on accurate monthly net cash burn inputs, often underestimated
Industry Benchmarks
For subscription health programs, best practice is to maintain a cash buffer covering 12-18 months of net cash burn. Private clinics often target a minimum cash equal to 12 months of fixed costs plus a capex reserve-this model cites a specific minimum of $2,671,000, which should be compared to actual monthly burn to assess sufficiency.
How To Improve
Collect upfront or stagger payments to match cash outflows
Negotiate payment terms with diagnostic labs and device suppliers
Delay non‑essential capex (e.g., RMR equipment) until revenue milestones hit
Focus first on revenue per active client, CAC, retention, gross margin, and cash runway Track 5 core KPIs and measure progress monthly across the 12-month program phases Compare Year 1 revenue of $840,000 to Year 3 revenue of $5,320,000 to validate trajectory and adjust spend accordingly
Review operational KPIs weekly and financial KPIs monthly for accurate decision-making Weekly checks catch sales and referral issues while monthly reviews align to accounting and cash flow Use quarterly strategy reviews tied to revenue milestones like Year 2 $2,570,000 and Year 3 $5,320,000 for course correction
Aim to retain a majority of enrolled clients through the 12-month program, then convert a meaningful portion to maintenance Track cohort retention across 3 phases and aim to materially improve Year-over-Year retention by Year 3 when revenue scales toward $5,320,000
Yes, plan to hold a minimum cash buffer to cover operations and growth needs this model cites a minimum cash of $2,671,000 Align runway planning to the critical month Jan-28 and include planned capex like $75,000 RMR equipment to avoid liquidity gaps
Measure marketing ROI by CAC, conversion rate, and revenue attributed per channel versus marketing spend percentage of revenue Track marketing percent trends from Year 1 to Year 5 and tie results to revenue milestones such as $840,000 in Year 1 and $11,180,000 in Year 5
