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
- Vanity Metrics — Focus on actionable metrics, not total users or page views
- Too Many Metrics — Track 5-7 core metrics intensely, not 50 loosely
- Ignoring Unit Economics — CAC and LTV matter even at seed stage
- Not Segmenting — Break down by customer segment, channel, cohort
- Gaming Metrics — Optimize for real business outcomes, not dashboards
NEVER Do
- NEVER ignore unit economics at any stage — CAC and LTV are always critical
- NEVER track vanity metrics (total users, page views) without retention context
- NEVER report growth rates without absolute numbers — 100% growth from $1K is different from $1M
- NEVER skip segmentation — aggregate metrics hide important patterns
- NEVER confuse correlation with causation — investigate before concluding
- NEVER set targets without understanding your stage benchmarks
- NEVER present metrics without trend context — current value + growth rate + benchmark
- NEVER optimize for the metric instead of the underlying business outcome
