WHAT This Skill Does

Provides formulas, benchmarks, and guidance for:

• Revenue metrics (MRR, ARR, growth rates)
• Unit economics (CAC, LTV, payback period)
• Cash efficiency (burn rate, runway, burn multiple)
• SaaS-specific metrics (NDR, magic number, Rule of 40)
• Marketplace and consumer metrics
• Stage-appropriate focus areas

WHEN To Use

• Setting up startup analytics and dashboards
• Calculating CAC, LTV, or unit economics
• Preparing investor updates or pitch materials
• Evaluating business health and efficiency
• Understanding what metrics matter at each stage

Universal Startup Metrics

Revenue Metrics

MRR = Σ (Active Subscriptions × Monthly Price)
ARR = MRR × 12

MoM Growth = (This Month MRR - Last Month MRR) / Last Month MRR
YoY Growth = (This Year ARR - Last Year ARR) / Last Year ARR

Benchmarks:

Stage	Growth Target
Seed	15-20% MoM
Series A	10-15% MoM, 3-5x YoY
Series B+	100%+ YoY (Rule of 40)

Unit Economics

CAC = Total S&M Spend / New Customers Acquired
LTV = ARPU × Gross Margin% × (1 / Churn Rate)
LTV:CAC Ratio = LTV / CAC
CAC Payback = CAC / (ARPU × Gross Margin%)

Benchmarks:

Metric	Excellent	Good	Concerning
LTV:CAC	> 3.0	1.0-3.0	< 1.0
CAC Payback	< 12 months	12-18 months	> 24 months

Cash Efficiency

Monthly Burn = Monthly Revenue - Monthly Expenses
Runway (months) = Cash Balance / Monthly Burn Rate
Burn Multiple = Net Burn / Net New ARR

Burn Multiple Benchmarks:

Score	Assessment
< 1.0	Exceptional efficiency
1.0-1.5	Good
1.5-2.0	Acceptable
> 2.0	Inefficient

Target: Always maintain 12-18 months runway.

SaaS Metrics

Revenue Composition

Net New MRR = New MRR + Expansion MRR - Contraction MRR - Churned MRR

Retention Metrics

NDR (Net Dollar Retention) = (ARR Start + Expansion - Contraction - Churn) / ARR Start
Gross Retention = (ARR Start - Churn - Contraction) / ARR Start
Logo Retention = (Customers End - New Customers) / Customers Start

NDR Benchmarks:

Range	Assessment
> 120%	Best-in-class
100-120%	Good
< 100%	Needs work

Efficiency Metrics

Magic Number = Net New ARR (quarter) / S&M Spend (prior quarter)
Rule of 40 = Revenue Growth Rate% + Profit Margin%
Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)

Magic Number:

• 0.75 = Efficient, ready to scale

• 0.5-0.75 = Moderate efficiency
• < 0.5 = Inefficient, don't scale yet

Marketplace Metrics

GMV = Σ (Transaction Value)
Take Rate = Net Revenue / GMV

Typical Take Rates:

Type	Range
Payment processors	2-3%
E-commerce marketplaces	10-20%
Service marketplaces	15-25%
High-value B2B	5-15%

Liquidity Indicators:

• Fill rate > 80% = Strong liquidity
• Repeat rate > 60% = Strong retention

Consumer/Mobile Metrics

DAU/MAU Ratio = DAU / MAU
K-Factor = Invites per User × Invite Conversion Rate

DAU/MAU Benchmarks:

Ratio	Assessment
> 50%	Exceptional (daily habit)
20-50%	Good
< 20%	Weak engagement

Retention Benchmarks (Day 30):

Rate	Assessment
> 40%	Excellent
25-40%	Good
< 25%	Weak

B2B Sales Metrics

Win Rate = Deals Won / Total Opportunities
Pipeline Coverage = Total Pipeline Value / Quota (target: 3-5x)
ACV = Total Contract Value / Contract Length (years)

Sales Cycle Benchmarks:

Segment	Typical Duration
SMB	30-60 days
Mid-market	60-120 days
Enterprise	120-270 days

Metrics by Stage

Pre-Seed (Product-Market Fit)

Focus: Active users, retention (Day 7/30), engagement, qualitative feedback

Don't worry about: Revenue, CAC, unit economics

Seed ($500K-$2M ARR)

Focus:

• MRR growth rate (15-20% MoM)
• CAC and LTV baselines
• Gross retention (> 85%)
• Core product engagement

Start tracking: Sales efficiency, burn rate, runway

Series A ($2M-$10M ARR)

Focus:

• ARR growth (3-5x YoY)
• LTV:CAC > 3, payback < 18 months
• NDR > 100%
• Burn multiple < 2.0
• Magic number > 0.5

What Investors Want to See

Seed Round

• MRR growth rate
• User retention
• Early unit economics
• Product engagement

Series A

• ARR and growth rate
• CAC payback < 18 months
• LTV:CAC > 3.0
• NDR > 100%
• Burn multiple < 2.0

Series B+

• Rule of 40 > 40%
• Efficient growth (magic number)
• Path to profitability

Dashboard Format:

Current MRR: $250K (↑ 18% MoM)
ARR: $3.0M (↑ 280% YoY)
CAC: $1,200 | LTV: $4,800 | LTV:CAC = 4.0x
NDR: 112% | Logo Retention: 92%
Burn: $180K/mo | Runway: 18 months

Common Mistakes

1. Vanity Metrics — Focus on actionable metrics, not total users or page views
2. Too Many Metrics — Track 5-7 core metrics intensely, not 50 loosely
3. Ignoring Unit Economics — CAC and LTV matter even at seed stage
4. Not Segmenting — Break down by customer segment, channel, cohort
5. Gaming Metrics — Optimize for real business outcomes, not dashboards

NEVER Do

1. NEVER ignore unit economics at any stage — CAC and LTV are always critical
2. NEVER track vanity metrics (total users, page views) without retention context
3. NEVER report growth rates without absolute numbers — 100% growth from $1K is different from $1M
4. NEVER skip segmentation — aggregate metrics hide important patterns
5. NEVER confuse correlation with causation — investigate before concluding
6. NEVER set targets without understanding your stage benchmarks
7. NEVER present metrics without trend context — current value + growth rate + benchmark
8. NEVER optimize for the metric instead of the underlying business outcome
