Startup Metrics Framework

Comprehensive guide to tracking, calculating, and optimizing key performance metrics for different startup business models from seed through Series A.

Overview

Track the right metrics at the right stage. Focus on unit economics, growth efficiency, and cash management metrics that matter for fundraising and operational excellence.

Universal Startup Metrics

Revenue Metrics

MRR (Monthly Recurring Revenue)

MRR = Σ (Active Subscriptions × Monthly Price)

ARR (Annual Recurring Revenue)

ARR = MRR × 12

Growth Rate

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

Target Benchmarks:

Seed stage: 15-20% MoM growth
Series A: 10-15% MoM growth, 3-5x YoY
Series B+: 100%+ YoY (Rule of 40)

Unit Economics

CAC (Customer Acquisition Cost)

CAC = Total S&M Spend / New Customers Acquired

Include: Sales salaries, marketing spend, tools, overhead

LTV (Lifetime Value)

LTV = ARPU × Gross Margin% × (1 / Churn Rate)

Simplified:

LTV = ARPU × Average Customer Lifetime × Gross Margin%

LTV:CAC Ratio

LTV:CAC = LTV / CAC

Benchmarks:

LTV:CAC > 3.0 = Healthy
LTV:CAC 1.0-3.0 = Needs improvement
LTV:CAC < 1.0 = Unsustainable

CAC Payback Period

CAC Payback = CAC / (ARPU × Gross Margin%)

Benchmarks:

< 12 months = Excellent
12-18 months = Good
24 months = Concerning

Cash Efficiency Metrics

Burn Rate

Monthly Burn = Monthly Revenue - Monthly Expenses

Negative burn = losing money (typical early-stage)

Runway

Runway (months) = Cash Balance / Monthly Burn Rate

Target: Always maintain 12-18 months runway

Burn Multiple

Burn Multiple = Net Burn / Net New ARR

Benchmarks:

< 1.0 = Exceptional efficiency
1.0-1.5 = Good
1.5-2.0 = Acceptable
2.0 = Inefficient

Lower is better (spending less to generate ARR)

SaaS Metrics

Revenue Composition

New MRR New customers × ARPU

Expansion MRR Upsells and cross-sells from existing customers

Contraction MRR Downgrades from existing customers

Churned MRR Lost customers

Net New MRR Formula:

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

Retention Metrics

Logo Retention

Logo Retention = (Customers End - New Customers) / Customers Start

Dollar Retention (NDR - Net Dollar Retention)

NDR = (ARR Start + Expansion - Contraction - Churn) / ARR Start

Benchmarks:

NDR > 120% = Best-in-class
NDR 100-120% = Good
NDR < 100% = Needs work

Gross Retention

Gross Retention = (ARR Start - Churn - Contraction) / ARR Start

Benchmarks:

90% = Excellent
85-90% = Good
< 85% = Concerning

SaaS-Specific Metrics

Magic Number

Magic Number = Net New ARR (quarter) / S&M Spend (prior quarter)

Benchmarks:

0.75 = Efficient, ready to scale
0.5-0.75 = Moderate efficiency
< 0.5 = Inefficient, don't scale yet

Rule of 40

Rule of 40 = Revenue Growth Rate% + Profit Margin%

Benchmarks:

40% = Excellent
20-40% = Acceptable
< 20% = Needs improvement

Example: 50% growth + (10%) margin = 40% ✓

Quick Ratio

Quick Ratio = (New MRR + Expansion MRR) / (Churned MRR + Contraction MRR)

Benchmarks:

4.0 = Healthy growth
2.0-4.0 = Moderate
< 2.0 = Churn problem

Marketplace Metrics

GMV (Gross Merchandise Value)

Total Transaction Volume:

GMV = Σ (Transaction Value)

Growth Rate:

GMV Growth Rate = (Current Period GMV - Prior Period GMV) / Prior Period GMV

Target: 20%+ MoM early-stage

Take Rate

Take Rate = Net Revenue / GMV

Typical Ranges:

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

Marketplace Liquidity

Time to Transaction How long from listing to sale/match?

Fill Rate % of requests that result in transaction

Repeat Rate % of users who transact multiple times

Benchmarks:

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

Marketplace Balance

Supply/Demand Ratio: Track relative growth of supply and demand sides.

Warning Signs:

Too much supply: Low fill rates, frustrated suppliers
Too much demand: Long wait times, frustrated customers

Goal: Balanced growth (1:1 ratio ideal, but varies by model)

Consumer/Mobile Metrics

Engagement Metrics

DAU (Daily Active Users) Unique users active each day

MAU (Monthly Active Users) Unique users active each month

DAU/MAU Ratio

DAU/MAU = DAU / MAU

Benchmarks:

50% = Exceptional (daily habit)
20-50% = Good
< 20% = Weak engagement

Session Frequency Average sessions per user per day/week

Session Duration Average time spent per session

Retention Curves

Day 1 Retention: % users who return next day Day 7 Retention: % users active 7 days after signup Day 30 Retention: % users active 30 days after signup

Benchmarks (Day 30):

40% = Excellent
25-40% = Good
< 25% = Weak

Retention Curve Shape:

Flattening curve = good (users becoming habitual)
Steep decline = poor product-market fit

Viral Coefficient (K-Factor)

K-Factor = Invites per User × Invite Conversion Rate

Example: 10 invites/user × 20% conversion = 2.0 K-factor

Benchmarks:

K > 1.0 = Viral growth
K = 0.5-1.0 = Strong referrals
K < 0.5 = Weak virality

B2B Metrics

Sales Efficiency

Win Rate

Win Rate = Deals Won / Total Opportunities

Target: 20-30% for new sales team, 30-40% mature

Sales Cycle Length Average days from opportunity to close

Shorter is better:

SMB: 30-60 days
Mid-market: 60-120 days
Enterprise: 120-270 days

Average Contract Value (ACV)

ACV = Total Contract Value / Contract Length (years)

Pipeline Metrics

Pipeline Coverage

Pipeline Coverage = Total Pipeline Value / Quota

Target: 3-5x coverage (3-5x pipeline needed to hit quota)

Conversion Rates by Stage:

Lead → Opportunity: 10-20%
Opportunity → Demo: 50-70%
Demo → Proposal: 30-50%
Proposal → Close: 20-40%

Metrics by Stage

Pre-Seed (Product-Market Fit)

Focus Metrics:

Active users growth
User retention (Day 7, Day 30)
Core engagement (sessions, features used)
Qualitative feedback (NPS, interviews)

Don't worry about:

Revenue (may be zero)
CAC (not optimizing yet)
Unit economics

Seed ($500K-$2M ARR)

Focus Metrics:

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

Start tracking:

Sales efficiency
Burn rate and runway

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

Focus Metrics:

ARR growth (3-5x YoY)
Unit economics (LTV:CAC > 3, payback < 18 months)
Net dollar retention (> 100%)
Burn multiple (< 2.0)
Magic number (> 0.5)

Mature tracking:

Rule of 40
Sales efficiency
Pipeline coverage

Metric Tracking Best Practices

Data Infrastructure

Requirements:

Single source of truth (analytics platform)
Real-time or daily updates
Automated calculations
Historical tracking

Tools:

Mixpanel, Amplitude (product analytics)
ChartMogul, Baremetrics (SaaS metrics)
Looker, Tableau (BI dashboards)

Reporting Cadence

Daily:

MRR, active users
Sign-ups, conversions

Weekly:

Growth rates
Retention cohorts
Sales pipeline

Monthly:

Full metric suite
Board reporting
Investor updates

Quarterly:

Trend analysis
Benchmarking
Strategy review

Common Mistakes

Mistake 1: Vanity Metrics Don't focus on:

Total users (without retention)
Page views (without engagement)
Downloads (without activation)

Focus on actionable metrics tied to value.

Mistake 2: Too Many Metrics Track 5-7 core metrics intensely, not 50 loosely.

Mistake 3: Ignoring Unit Economics CAC and LTV are critical even at seed stage.

Mistake 4: Not Segmenting Break down metrics by customer segment, channel, cohort.

Mistake 5: Gaming Metrics Optimize for real business outcomes, not dashboard numbers.
