What Are Unit Economics (And Why Should You Care?)

Unit economics is a fancy term for understanding how much profit you make on every sale or customer, after all your costs.
It’s about answering one simple question:

“For every new patient or client I get, do I actually make money?”

If you run ads on Google, Instagram, or anywhere else, and you don’t know your unit economics, you’re flying blind.

Unit economics is the hidden engine behind why some medspas dominate Google or Meta ads, while others get zero traction.

Why Does This Matter for Clinics?

In cosmetics, customer value, margins, and acquisition costs vary a lot between services like Botox, fillers, facials, laser hair removal, and packages. You can’t afford guesswork.

Great unit economics means you can outbid competitors, scale your campaigns, and grow profitably—without burning through your cash.

 

The Real Reason Your Marketing Might Be Stuck

You’ve probably wondered:

  • Why are some clinics at the top of Google ads all year, while I can’t break into the top 3?
  • Why are my leads expensive—or my campaigns unprofitable, even when my ads look great?
  • Why is scaling my spend so hard—every extra dollar seems to bring less in return?

It often comes down to this:

Their unit economics are stronger than yours—or they just know their numbers better.

A quick story from my own experience:

When I first started helping medspas with digital marketing, I was shocked.

Sometimes, even with amazing ad copy, landing pages, and targeting, the campaigns still lost money.

It wasn’t the ads. It was the math underneath:

  • Low margins on popular treatments
  • Expensive customer acquisition
  • Weak follow-up or poor conversion

When we fixed the unit economics, everything else fell into place.

3. Breaking Down Unit Economics for Clinics

Let’s keep this simple and practical. Here’s how unit economics looks for your clinic:

Key concepts:

  • Average Order Value (AOV): What does the typical client spend per visit or transaction?
  • Gross Margin: How much profit is left after you pay your suppliers, staff, and costs?
  • Customer Acquisition Cost (CAC): How much do you spend on marketing to bring in a single paying client?
  • Lifetime Value (LTV): How much does a client spend with you over their relationship with your clinic?
  • Conversion Rates: What % of inquiries or leads actually become paying clients?

Each metric tells you something vital about whether your business can thrive, scale, and win in today’s competitive market.

The Simple Math

Gross Profit per Client = AOV x Gross Margin (%)

Net Profit per Client = Gross Profit – CAC

If Net Profit per Client is positive, your campaigns are scalable. If not, you need to adjust—fast!

 

Essential Metrics: The Numbers That Matter Most

Let’s break these down with formulas, examples, and benchmarks relevant to clinics and medspas.

A. Average Order Value (AOV)

How much does a client spend on an average visit?

Formula:

AOV = Total Revenue / Number of Transactions

Example:

Last month, you generated $32,000 from 200 transactions:

  • AOV = $32,000 / 200 = $160

Why It Matters:
A higher AOV gives you more margin to spend on marketing. If AOV is low (e.g., from single low-cost treatments), your marketing gets squeezed.

B. Gross Margin (%)

How much profit do you keep after direct costs?

Formula:

Gross Margin = (Revenue – Cost of Goods Sold) / Revenue

Example:

  • Revenue: $160 (from above)
  • Cost of treatment supplies, staff time, disposables: $100
  • Gross Margin = ($160 – $100) / $160 = 37.5%

Benchmark:
Most medspas should target 50–70% gross margin depending on service mix.

If you’re below 40%, it’s hard to grow profitably, especially with paid ads.


C. Customer Acquisition Cost (CAC)

How much does it cost to bring in a new paying client?

Formula:
CAC = Total Marketing Spend / Number of New Clients Acquired

Example:

  • You spend $2,400 on Google Ads in a month
  • 24 new, first-time clients book and show up
  • CAC = $2,400 / 24 = $100

Reality Check:
If your average profit per client is $60, but it costs $100 to get them in the door, you’re losing $40 per client (before overheads). Ouch.


D. Lifetime Value (LTV)

How much will a typical client spend with you over their relationship with your clinic?

Formula:
LTV = AOV x Number of Visits per Year x Average Years as a Client x Gross Margin (%)

Example:

  • AOV = $160
  • Clients visit 3 times per year
  • Stay on average 2 years
  • Gross Margin = 37.5%
  • LTV = $160 x 3 x 2 x 0.375 = $360

Tip:
Many clinics underestimate LTV by only looking at the first transaction. Loyal clients are worth way more.


E. Conversion Rate

What percentage of leads become paying clients?

Formula:
Conversion Rate = Number of Booked Appointments / Number of Leads x 100

Example:

  • 40 booked appointments from 100 inquiries = 40% conversion rate

Industry Reality:

  • Average is around 20-40%—but top-performing clinics can achieve 50%+ by focusing on fast follow-up and strong sales scripts.


F. Break-even ROAS (Return on Ad Spend)

How much revenue do you need for every dollar spent on ads, just to break even?

Formula:
Break-even ROAS = 1 / Gross Margin (%)

Example:

  • If gross margin is 37.5%, Break-even ROAS = 1 / 0.375 = 2.67x (or 267%)

You need $2.67 in revenue for every $1 in ad spend, just to cover direct costs. Profit requires even higher ROAS!


Let’s pause and recap:

If you don’t know these numbers, you’re guessing. But once you do, you’ll see exactly how much you can afford to spend to acquire new clients—and where you might be leaving profit on the table.


How Unit Economics Drive Campaign Success or Failure

Let’s connect the dots: unit economics decides if your ads work.

Scenario A: Healthy Unit Economics

  • High AOV (thanks to packages or upsells)
  • Strong gross margins (well-managed costs)
  • Reasonable CAC (smart, targeted marketing)
  • Solid client retention (good LTV)

Result:
You can bid higher for keywords, attract more clients, out-market the competition, and grow profitably.


Scenario B: Poor Unit Economics

  • Low AOV (single low-margin treatments)
  • High cost of service (expensive products or labor)
  • High CAC (inefficient ads, low conversion)
  • Weak follow-up (poor retention or rebooking)

Result:
Campaigns are unscalable—raising your budget just loses more money. Your best competitors can afford to outbid you, and your team gets frustrated.


Real Numbers Example 

Let’s take this straight from the real-world numbers:

  • AOV: $100
  • Gross Margin: 40%
  • Gross Margin per Client: $40
  • CAC (Cost to Acquire a Client): Needs to be below $40 for profitability
  • Break-even ROAS: 2.5x (250%)—for every $1 spent on ads, you must get $2.50 in revenue

If your cost per booked client is $50, but your gross profit per client is only $40, every client you acquire loses you $10 before you even pay rent or staff.

This is why having a solid Google Ads strategy for medspas matters – you need campaigns that attract high-value clients, not just cheap clicks.


Table: How Changes Affect Profitability

Metric Strong Clinic Struggling Clinic
Average Order Value $250 $80
Gross Margin (%) 60% 25%
Gross Margin per Client $150 $20
CAC $80 $60
Net Profit per Client $70 -$40
Break-even ROAS 1.67x 4x

As you can see, a high-margin, high-ticket clinic can outbid, out-market, and outlast weaker competitors—every single time.


Case Study: Medspa Google Ads—From Struggle to Scale

Let’s get practical. Here’s a real example (numbers slightly changed for privacy, but based on true client cases):

Background

  • Clinic spent $3,300/month on Google Ads
  • Revenue from those ads: $40,200/month
  • Gross Margin: 12% (very low, due to heavy discounts and high staff costs)

Result:

  • Gross Profit: $4,824
  • Subtract ad spend: Net Profit = $1,524
  • Contribution Margin: Only 4%!

Despite big revenues, the actual take-home from ads was minimal—one rough month and they’d be in the red.

Why?

  • Over-discounting services
  • High cost of supplies and labor
  • Not enough upselling or cross-selling
  • No focus on retaining clients for repeat visits


What Turned It Around?

We worked with them to:

  • Raise prices on core treatments
  • Create high-margin packages and memberships
  • Upskill the front desk to rebook clients before they leave
  • Focus on Google Ads for higher-ticket services only

Three months later:

  • Gross margin improved to 30%
  • CAC dropped by 25% (better targeting and follow-up)
  • Break-even ROAS went from 8.3x (!) to a much more realistic 3x

Revenue grew, but profit grew much faster.


Fixing Common Problems: Real Solutions

Problem #1: Low Gross Margins

Common Causes:

  • Deep discounts on popular treatments
  • Over-staffing or inefficient scheduling
  • High product or supply costs

Solutions:

  • Focus on high-margin services or combine treatments into profitable packages
  • Review supplier contracts and negotiate better deals
  • Invest in staff training for efficiency


Problem #2: High Customer Acquisition Cost (CAC)

Common Causes:

  • Broad, untargeted ads
  • Slow or weak lead follow-up
  • Low conversion from inquiry to booked appointment

Solutions:


Problem #3: Low Average Order Value (AOV)

Common Causes:

  • Only selling single treatments
  • Missing out on upsells or product sales
  • Not offering packages or memberships

Solutions:

  • Bundle popular services (e.g., Botox + facial + take-home skincare)
  • Train staff to recommend add-ons
  • Implement a membership or loyalty program


Problem #4: Poor Conversion Rate from Leads

Common Causes:

  • Leads not qualified or not contacted quickly
  • Confusing offers or unclear pricing
  • Unskilled front desk or sales team

Solutions:

  • Pre-qualify leads with online forms (budget, needs, timeline)
  • Make pricing clear and transparent
  • Role-play booking calls with your team to boost their skills


Problem #5: Weak Client Retention / LTV

Common Causes:

  • No rebooking at checkout
  • No follow-up for lapsed clients
  • No incentives for repeat visits

Solutions:

  • Always rebook before the client leaves
  • Run reactivation campaigns (texts, emails)
  • Offer packages with built-in future visits or member benefits

Pro Tips: How We Help Our Partners

After working with dozens of clinics and medspas, here are some tried-and-true tips that really move the needle:


Know Your Numbers Cold

Before you spend more on ads, calculate your current:

  • AOV for each core service
  • Gross margin per treatment
  • CAC (monthly and by channel)
  • Conversion rates at each step (lead → consult → booked → paid)
  • Client LTV (segment by service if possible)

Tip: If you need help, ask your agency (that’s us!), your bookkeeper, or just start with a simple spreadsheet.


Fix Your Follow-Up

Speed is everything. We’ve seen clinics double their conversion rate simply by:

  • Calling/texting leads within 5 minutes
  • Using scripts that focus on empathy and value – scripts built from real voice of customer data perform significantly better because they use language your clients actually relate to, rather than industry jargon they don’t understand.
  • Booking directly into the schedule (no “We’ll call you back”)


Focus Ads on High-Margin Services

Not every treatment is worth advertising.

  • Calculate the true profit on each service
  • Run ads for services with high margins and/or high rebooking rates
  • Use packages to raise AOV and lock in repeat business


Leverage Memberships and Packages

Predictable revenue is gold.

  • Offer monthly facials, Botox “banks,” or VIP memberships
  • Bundle in product sales (retail margin can be >50%!)


Report, Refine, Repeat

You can’t improve what you don’t track.

  • Set a time each month to review your numbers—especially CAC, gross margin, and rebooking rates
  • Adjust your ad budget to favour the channels and services delivering the most profit, not just the most bookings. For more on this check out our tracking tips article


Don’t Be Afraid to Raise Prices

If your margins are tight, it’s often a sign you need to:

  • Review your pricing vs. market rates
  • Raise prices on underpriced services, or
  • Focus on services where you can command a premium


Ask for Feedback

Your team (and even your clients) can spot margin killers you might miss.
Regular team huddles often turn up big opportunities.
