What is Unit Economics? The Single Equation That Predicts Your Success

WeWork. Uber. MoviePass. Blue Apron. What killed them wasn't competition or bad products. It was unit economics.

They lost money on every transaction and tried to make it up in volume. Spoiler: That's not how math works.

Unit Economics: Business Success at the Atomic Level

Unit Economics = Revenue per Unit - Cost per Unit

The "unit" is your basic building block:

SaaS: One customer
E-commerce: One order
Marketplace: One transaction
Media: One user
Services: One project

If you make money on each unit, you can scale. If you lose money, scaling kills you faster.

The Unit Economics Reality Check

Three companies, same revenue:

Company A:

Revenue per customer: $100
Cost per customer: $80
Profit per unit: $20
Verdict: Scale aggressively

Company B:

Revenue per order: $50
Cost per order: $48
Profit per unit: $2
Verdict: Fix before scaling

Company C:

Revenue per user: $10
Cost per user: $15
Loss per unit: -$5
Verdict: Pivot or die

Same revenue. Completely different destinies.

The Core Unit Economics Formulas

For Subscription Businesses

Unit Economics = LTV - CAC

Where:
- LTV = Average Revenue per User × Gross Margin × Customer Lifetime
- CAC = Total Sales & Marketing Cost ÷ New Customers

Healthy: LTV:CAC > 3:1
Payback Period < 12 months

For E-commerce

Unit Economics = Average Order Value - (COGS + Fulfillment + Transaction Costs)

Contribution Margin = (AOV - Variable Costs) ÷ AOV

Healthy: Contribution Margin > 30%

For Marketplaces

Unit Economics = Take Rate - Cost to Serve

Net Revenue = Gross Transaction Value × Take Rate
Cost to Serve = CAC + Support + Payment Processing

Healthy: Positive after 6-12 months

For Media/Content

Unit Economics = Revenue per User - Cost per User

Revenue = (Ad Revenue + Subscription Revenue) ÷ Users
Cost = (Content + Tech + Support) ÷ Users

Healthy: Break-even at scale

Why Unit Economics Beats Everything Else

Better Than Revenue Growth

The Trap: "We're growing 300% yearly!" The Reality: Losing $50 on each sale The Future: Bankruptcy

The Trap: "We have 60% market share!" The Reality: In a market where nobody makes money The Future: Industry collapse

Better Than Gross Margins

The Trap: "80% gross margins!" The Reality: CAC is 5x LTV The Future: Can't afford growth

Unit economics tells you if your business model actually works.

The MoviePass Disaster: A Unit Economics Case Study

Their Model:

Customer pays: $9.95/month
Average movies watched: 3/month
Cost per movie ticket: $12
Total cost: $36
Loss per customer: -$26.05/month

Their Strategy: "We'll make it up with data and partnerships!" Reality: Burned $150M in 9 months Lesson: Hope is not a business model

Improving Unit Economics: The Four Levers

Lever 1: Increase Revenue per Unit

Tactics:

Raise prices (test 10-20%)
Upsell/cross-sell (add 20-30%)
Increase usage (drive engagement)
Add premium tiers

Example: Spotify Family Plan increased ARPU by 40%

Lever 2: Decrease Variable Costs

Focus Areas:

Negotiate supplier rates
Improve operational efficiency
Automate repetitive tasks
Reduce payment processing fees

Example: Amazon's fulfillment cost per package dropped 50% over 10 years

Lever 3: Extend Customer Lifetime

Methods:

Better onboarding
Product improvements
Customer success programs
Switching costs

Example: Netflix's recommendation engine extends average lifetime by 18 months

Lever 4: Reduce Acquisition Costs

Approaches:

Improve conversion rates
Build referral programs
Focus on organic growth
Better targeting

Example: Dropbox's referral program reduced CAC by 60%

Unit Economics by Business Stage

Startup Phase

Focus: Prove positive unit economics exist Acceptable: Negative for 6-12 months while learning Red Flag: No path to positive

Growth Phase

Focus: Improve unit economics while scaling Target: 20%+ contribution margin Red Flag: Deteriorating with growth

Scale Phase

Focus: Optimize for maximum profitability Target: Best-in-class for your industry Red Flag: Competition eroding margins

Mature Phase

Focus: Maintain while exploring new units Target: Steady state optimization Red Flag: Declining without innovation

The Cohort Analysis Method

Don't average all customers. Analyze by cohort:

Month 1 Cohort:

CAC: $100
Month 1 revenue: $50
Month 6 cumulative: $250
Month 12 cumulative: $400
Payback: Month 3
12-month LTV:CAC: 4:1

Track each monthly cohort. Look for:

Improving payback periods
Higher LTV:CAC ratios
Better retention curves

Common Unit Economics Mistakes

Mistake 1: Ignoring Support Costs

"Our gross margin is 90%!" Forgets customer support costs 20% of revenue

Mistake 2: Blending All Customers

Enterprise customers: LTV:CAC = 5:1 ✓ SMB customers: LTV:CAC = 0.8:1 ✗ Blended: 2:1 (looks ok, but half your business is dying)

Mistake 3: Excluding Refunds/Returns

Gross revenue per unit: $100 Returns: 30% Net revenue: $70 Many forget this adjustment

Mistake 4: The Scale Fallacy

"Unit economics will improve with scale" Only true if you have:

High fixed costs
Network effects
Economies of scale
