Essential Growth Metrics Every Startup Should Track

Tracking the right metrics can make the difference between a thriving startup and one that burns through cash without clear direction. Here's your guide to the essential metrics that actually matter.

Why Metrics Matter

In the startup world, metrics serve multiple critical purposes:

• Investor confidence: VCs want to see data-driven growth
• Strategic decisions: Metrics guide where to focus resources
• Team alignment: Everyone works toward the same goals
• Early warning system: Spot problems before they become critical

Core Financial Metrics

1. Monthly Recurring Revenue (MRR)

For SaaS and subscription businesses, MRR is the north star metric.

// Calculate MRR
const calculateMRR = (subscriptions: Subscription[]) => {
  return subscriptions.reduce((total, sub) => {
    const monthlyValue = sub.billingCycle === 'annual' 
      ? sub.amount / 12 
      : sub.amount;
    return total + monthlyValue;
  }, 0);
};

Why it matters: MRR provides predictable revenue forecasting and shows business momentum.

2. Customer Acquisition Cost (CAC)

How much does it cost to acquire a new customer?

Formula: CAC = Total Sales & Marketing Spend / Number of New Customers

3. Lifetime Value (LTV)

The total revenue you can expect from a customer over their entire relationship.

Formula: LTV = Average Revenue Per User × Gross Margin % × (1 / Churn Rate)

4. LTV:CAC Ratio

The golden ratio that determines if your business model is sustainable.

• < 1: Losing money on every customer
• 1-3: Concerning, may not be sustainable
• 3+: Healthy, sustainable growth
• > 5: May be under-investing in growth

Growth Metrics

1. Monthly Active Users (MAU)

Tracks user engagement and product stickiness.

-- Example SQL for calculating MAU
SELECT 
  DATE_TRUNC('month', activity_date) as month,
  COUNT(DISTINCT user_id) as monthly_active_users
FROM user_activities 
WHERE activity_date >= CURRENT_DATE - INTERVAL '12 months'
GROUP BY month
ORDER BY month;

2. Churn Rate

The percentage of customers who stop using your product.

Monthly Churn Rate: (Customers Lost in Month / Customers at Start of Month) × 100

3. Net Revenue Retention (NRR)

Measures revenue growth from existing customers.

Formula: NRR = (Starting MRR + Expansion - Contraction - Churn) / Starting MRR × 100

• > 100%: Growing revenue from existing customers
• < 100%: Losing revenue from existing customers

Product Metrics

1. Product-Market Fit Indicators

Sean Ellis Test

Survey users: "How would you feel if you could no longer use this product?"

• > 40% "Very disappointed": Strong product-market fit signal

Net Promoter Score (NPS)

"How likely are you to recommend this product to a friend?"

• 0-6: Detractors
• 7-8: Passives
• 9-10: Promoters

NPS = % Promoters - % Detractors

2. Feature Adoption Rate

Tracks how well new features are being adopted.

const calculateFeatureAdoption = (feature: string, timeframe: number) => {
  const totalUsers = getTotalActiveUsers(timeframe);
  const featureUsers = getUsersUsingFeature(feature, timeframe);
  return (featureUsers / totalUsers) * 100;
};

3. Time to Value (TTV)

How quickly do users experience value from your product?

Measure: Time from signup to first "aha moment" or key action

Sales Metrics

1. Sales Velocity

How quickly deals move through your pipeline.

Formula: Sales Velocity = (Number of Opportunities × Average Deal Size × Win Rate) / Sales Cycle Length

2. Pipeline Coverage

Ensures you have enough pipeline to hit revenue targets.

Formula: Pipeline Coverage = Total Pipeline Value / Revenue Target

Benchmark: 3-5x coverage is typically healthy

3. Lead Conversion Rates

Track conversion at each stage of your funnel.

| Stage | Typical B2B SaaS Rate | | --- | --- | | Visitor to Lead | 2-5% | | Lead to Opportunity | 10-15% | | Opportunity to Customer | 15-25% |

Operational Metrics

1. Burn Rate

How quickly you're spending money.

Gross Burn: Total monthly expenses Net Burn: Gross burn minus revenue

2. Runway

How long your money will last.

Formula: Runway = Cash Balance / Monthly Net Burn

3. Cash Efficiency

How effectively you're using cash to drive growth.

Formula: Cash Efficiency = Revenue Growth / Cash Burned

Setting Up Your Metrics Dashboard

Essential Tools

• Analytics: Google Analytics, Mixpanel, Amplitude
• CRM: Salesforce, HubSpot, Pipedrive
• Financial: QuickBooks, Xero, ProfitWell
• Dashboard: Tableau, Looker, Metabase

Dashboard Best Practices

1. Keep it simple: Focus on 5-10 key metrics
2. Real-time data: Update frequently for accurate insights
3. Visual hierarchy: Most important metrics prominently displayed
4. Context matters: Show trends, not just point-in-time data
5. Actionable insights: Include targets and benchmarks

Sample Executive Dashboard

# Executive Dashboard - [Month Year]

## Financial Health
- MRR: $X (+Y% MoM)
- ARR: $X (+Y% YoY)
- Burn Rate: $X/month
- Runway: X months

## Growth
- New Customers: X (+Y% MoM)
- Churn Rate: X% (target: under 5%)
- NRR: X% (target: >110%)
- CAC: $X (target: <$Y)

## Product
- MAU: X (+Y% MoM)
- Feature Adoption: X%
- NPS: X (target: >50)
- Support Tickets: X (-Y% MoM)

Common Metrics Mistakes

1. Vanity Metrics

Metrics that look good but don't drive business decisions:

• Total users (without engagement context)
• Page views (without conversion context)
• Social media followers (without engagement)

2. Too Many Metrics

Tracking everything leads to analysis paralysis. Focus on metrics that:

• Drive specific actions
• Align with business goals
• Can be influenced by your team

3. Ignoring Cohort Analysis

Looking at aggregate data can hide important trends. Always segment by:

• Customer acquisition date
• Customer segment
• Product usage patterns
• Geographic region

Metrics by Business Stage

Pre-Product Market Fit

• User engagement metrics
• Product usage patterns
• Customer feedback scores
• Feature adoption rates

Post-Product Market Fit

• Revenue growth metrics
• Customer acquisition efficiency
• Market expansion indicators
• Operational efficiency metrics

Scale Stage

• Unit economics optimization
• Market share metrics
• Competitive positioning
• Organizational efficiency

Taking Action on Your Metrics

Metrics are only valuable if they drive action:

1. Set clear targets: Every metric needs a goal
2. Regular reviews: Weekly/monthly metric reviews
3. Root cause analysis: Understand why metrics change
4. Experiment and iterate: Use metrics to guide experiments
5. Communicate broadly: Share insights across the organization
