Calculator 1

Injectable Gross Margin Calculator

Enter your monthly injectable revenue and vendor product costs. See your real gross margin after Allergan, Galderma, and Merz COGS — not the inflated number QuickBooks shows by default.

Your inputs

Monthly injectable service revenue Total neurotoxin + filler revenue from your booking system

$

Allergan invoices (month) Total paid to Allergan for Botox, Juvederm, Kybella

$

Galderma invoices (month) Restylane, Sculptra, Dysport

$

Other vendor invoices (month) Merz, Evolus, Revance, any other injectable vendor

$

Your results

Enter your revenue and vendor costs above.

Benchmark: 60–70% is healthy. Below 55% indicates a pricing, waste, or vendor cost problem. Above 75% usually means vendor invoices are incomplete.

Calculator 2

Device ROI & Break-Even Calculator

Enter your device lease payment, average treatment price, and weekly treatment volume. See exactly how many treatments per week you need to break even — and whether you are above or below that line.

Your inputs

Monthly lease payment Your fixed monthly payment for the device (Morpheus8, CoolSculpting, Sciton HALO, etc.)

$

Average treatment price (net) What you charge per session, minus consumables (tips, gels, handpiece cost per session)

$

Actual sessions per week Average weekly treatment volume for this device over the last 4 weeks

/ wk

Your results

Break-even sessions per week —

Break-even sessions per month —

Monthly treatment revenue (actual) —

Monthly surplus / deficit vs. lease —

Device status

—

Enter your lease payment and treatment price above.

This calculation covers the lease payment only — not provider labor, allocated overhead, or consumables beyond what you entered in the treatment price. Factor in full costs to assess true service-line profitability.

Calculator 3

Revenue Per Provider

Total practice revenue divided by full-time providers shows whether each clinician is producing at benchmark. Below $45k per provider is usually a volume or pricing problem. Above $100k means mature providers or a high-ticket service mix.

Your inputs

Total monthly practice revenue All service revenue across the practice this month

$

Number of providers (FTE) Count nurses, NPs, and MDs as full-time-equivalents. Two part-time = 1 FTE

FTE

Provider-driven share of revenue Percentage of revenue tied to provider services. Exclude memberships, retail, aesthetician-only services

%

Your results

Provider-attributable revenue / month —

Annualized revenue / provider —

Revenue per provider / month

—

Enter your revenue and provider count above.

Benchmark for injectable-led med spas: $50k–$80k per provider per month. High-ticket surgical or membership-heavy practices clear $100k. Use this as a hiring and pricing signal, not a comp formula.

Calculator 4

Revenue Per Treatment Room (per hour)

Treatment rooms are your second largest fixed cost after labor. If a room is generating less than $120 per operating hour, the room is dragging margin. This calc shows what each room earns per hour you keep the lights on.

Your inputs

Monthly revenue from rooms All service revenue produced inside treatment rooms (exclude retail and consults)

$

Number of treatment rooms Rooms used for billable services. Storage and break rooms do not count

rooms

Open hours per week Total hours rooms are available for treatment, not booked hours

hrs/wk

Your results

Revenue per room per month —

Total open hours per month —

Revenue per room / hour

—

Enter your revenue, rooms, and hours above.

Below $120 per hour per room means underutilized capacity or low pricing. $120–$250 is the healthy range for injectable + laser practices. Above $250 indicates premium service mix or exceptional booking density.

Calculator 5

Patient Lifetime Value (LTV)

A new patient is not worth one visit. They are worth every visit they make until they leave. LTV tells you the gross profit a patient produces over their full tenure. Use it to size acquisition spend.

Your inputs

Average ticket per visit Weighted average across injectables, lasers, facials, packages

$

Visits per patient per year 3–6 is typical depending on injectable cadence and membership status

visits

Average patient tenure (years) How long the typical patient remains active. 2–5 years is normal

yrs

Gross margin on services After product COGS and direct labor, before overhead

%

Your results

Lifetime gross revenue per patient —

Annual revenue per patient —

Lifetime gross profit per patient

—

Enter your inputs above.

A healthy med spa LTV is $4,000+. Below $3,000 means short patient tenure or low frequency. Pair this calc with the CAC calc below — sustainable acquisition cost is roughly 25–30% of LTV.

Calculator 6

Marketing Cost Per Acquisition (CAC)

CAC is the total marketing spend it took to land one new patient. Compared against LTV, it tells you whether your acquisition is sustainable or a treadmill. Below 3:1 LTV-to-CAC is a warning sign.

Your inputs

Monthly marketing spend All paid channels plus agency fees, content, software

$

New patients acquired this month First-time patients only. Returning patients do not count

patients

Patient LTV (gross profit) Use the result from the LTV calc above

$

Your results

Cost per acquisition —

LTV-to-CAC ratio —

Acquisition health

—

Enter your spend, new patients, and LTV above.

3:1 LTV-to-CAC is the floor. 4:1 to 6:1 is healthy. Below 3:1 means you are spending too much on acquisition relative to what each patient pays back. Track this monthly to catch channel decay.

Calculator 7

Provider Productivity

Productivity is revenue per billable hour, less direct compensation. It tells you what a provider clears for the practice after their own paycheck. Use it to validate comp structures and spot scheduling drift.

Your inputs

Billable hours per week Hours actually performing services. Subtract admin, breaks, no-shows from clock hours

hrs

Average revenue per billable hour Pull from your booking system. $200–$400 typical for injectables and lasers

$

Provider compensation as % of revenue Total comp including base, commission, benefits. Typical 25–45%

%

Your results

Provider weekly revenue —

Provider monthly revenue —

Provider compensation cost —

Margin per provider / month

—

Enter your hours, rate, and comp above.

Margin per provider should clear $6,000 per month at minimum to cover allocated overhead. Below that, the provider is not pulling their weight against rent and shared cost. Above $15,000 means raise the comp or risk losing them.

Calculator 8

Treatment Mix Profitability

Three service lines, three margins. This calc shows where your gross profit actually comes from, not where revenue comes from. The two are not the same. The highest revenue line is rarely the highest margin line.

Your inputs

Service line 1 revenue (Injectables) Monthly Botox, Dysport, fillers

$

Service line 1 COGS % Vendor product cost as % of revenue. Typical 20–28% for injectables

%

Service line 2 revenue (Devices) Laser, RF microneedling, body contouring

$

Service line 2 COGS % Consumables only — lease is operating expense, not COGS. Typical 8–15%

%

Service line 3 revenue (Other) Facials, microneedling, peels, packages

$

Service line 3 COGS % Product and consumable cost. Typical 15–22% for non-injectable services

Highest-margin service line

—

Enter your service line revenue and COGS above.

Schedule the highest-margin service line first when capacity is constrained. If injectables are 65% of profit but only 40% of revenue, that is where every marketing dollar should go. Devices typically carry the highest margin once paid off.

Calculator 9

Staffing Cost Ratio

Total payroll as a percentage of revenue is the single most important ratio in service businesses. Above 40% and you cannot fund anything else. Below 25% you are usually underinvesting in retention or burning out staff.

Your inputs

Monthly revenue Total practice revenue this month

$

Total monthly payroll cost All wages, benefits, payroll taxes, contractor pay. Owner draw is separate

$

Number of FTE staff All providers, front desk, aestheticians, admin combined

FTE

Your results

Average comp per FTE —

Payroll % of revenue

—

Enter your revenue and payroll above.

Healthy med spa range is 28–35% of revenue on payroll. Surgical or membership-heavy practices run lower. Solo-provider practices run higher. Above 40% = restructure schedule or pricing. Below 22% = quality and retention risk.

Calculator 10

Gross & Net Profit Margins

A full P&L stack from revenue to net profit. Gross margin tells you whether your pricing covers product cost. Net margin tells you whether the business actually keeps money after rent, payroll, marketing, and everything else.

Your inputs

Monthly revenue All service and retail revenue

$

Total COGS Injectable product + device consumables + retail cost

$

Payroll + benefits All compensation including taxes
